Breathless Reaction Paper Essay

Katherine Paler- Rivera According to the many articles and film history that I read, this is the first feature film directed by Jean- Luc Godard who was considered the influencial director that started the French New Wave. And based on our lectures, what makes the French New Wave famous was the technique like jumpcuts, shooting on location, using handheld cameras, loose narrative form or improvised dialogue. Godard also uses the history of cinema art and music. He also includes pictures in posters of famous artists like Picasso and Renoir women. The music in the soundtrack also includes Mozart’s clarinet concerto and French pop radio. The entire story started when the character of Michel Poiccard which Jean Paul Belmondo portrays, has stolen a car. While he was driving he passed by two hitch hikers and decides to decline for the thought they were far too ugly for him. Then suddenly, he realized that the cops was behind him. He hid on the side of the street. Thinking he got away he feels relieved. But suddenly a cop found him. He was shocked and unconsciously because of his instinct killed the cop. It was not shown how he shot the cop, it was suggested because the next scene, the cop falls down in the bushes. Then he runs away in an open field. In Paris, he called up somebody on the phone but no one is answering. Then he bought a newspaper from a boy in a bicyle, browse it a bit then head to an apartment employee asking for that somebody. He just took the keys when the man was not looking. Next scene he was inside the room. He just had a quick time in the wash room to freshen up. He was looking for money in the drawer but he was disappointed. He took a newspaper, read a bit then rubs in in his shoes. Then a some girl opens the door and let him in. The room was full of posters of girls. He was asking for money. While the girl was changing, Michel easily took the money in her wallet. Then in the next scene he was on the streets looking for a girl. It was Patricia Franchini who was portrayed by Jean Seberg. She was studying journalism whom he had met in Nice a few weeks earlier. She was selling New York Herald Tribune. Michel was having a conversation with him about what had happen in their stay in Nice, his women and their plans. He asks for a copy of the newspaper but return it once he realized it had no horoscope. They were planning to see each other on the same same street when the day ends. When they parted, he saw a newspaper stand, bought a copy. Patricia rushed through him and gave him a quick smack on the cheek. Right then and there I observed that these two were an item. In the building where he got inside, he was looking for a guy friend named Tolmachov.. They talked about certain guys common to them. Then his friend handed him an envelope which he was not please. He was given a certain phone number that he called. Then he bid goodbye. Two gentlemen came inside the building, the bigger man I knew was an inspector. He was asking for Michel or a certain other name. At first Tomalchov denied he saw Michel but they were busted when a girl passed by and the detective asked her if he saw Tomalchov with a man 5 minutes ago. He was also reminded that accessory of a murder is a crime. I find Michel’s character rude, proud, dishonest and self centered. He likes to have everything easy without trying to work on it. Examples are the cars he stolen, the man he beat up in the comfort room so he can have money. I don’t think the respect Patricia. He â€Å"uses† people and loves to use the word â€Å"louse†. He almost always has a cigarette on her mouth which makes me annoyed. Some critic said he made it sexy but I don’t find it appealing. As usual he always has a newspaper but I don’t think he paid for it. He wore sunglassed even if its late in the afternoon which I find truly absurd. Patricia’s character gets into my nerve. I hate movies that shows women they are like a â€Å"thing to be used†. I don’t like if someone used bad words to a woman. Good for him that he told the police about Michel. The background music also bores me. They keep on using it again and again. Except for the classical music they played when they were inside Patricia’s room. There was also this scene when Patricia was interviewing a man alongside other journalist. When she asked â€Å"What’s your greatest ambiton? † The man replied, â€Å" To become immortal and then die. † Patricia took off her sunglasses, think deeply and face the camera as if connecting to the viewers. In the scene where he called the cops about Michel, she even talked to him hear to heart. She love him that’s why she gave him away which made him furious. According to Wikipedia, â€Å"Godard envisaged Breathless as a reportage (documentary), and asked the Cinematographer Raoul Coutard to shoot the entire film on a hand- held camera, with next to no lighting. In order to shoot under low light levels, Coutard had to use liford HPS film, which was not available as motion picture film stock at the time. He therefore took 18 metre lengths of HPS film sold for 35mm still cameras and spliced them together to 120 metre rolls. During development he pushed the negative one stop from 400 ASA to 800 ASA. The size of the sprocket holes for motion picture film and the Cameflex camera was the only camera that would work for the film used. † â€Å"The production was filmed on location in Paris during the months of August and September in 1959, using an Eclair Cameflex. Almost the whole film had to be dubbed in post- production because of the noisiness of the Cameflex camera and because the Cameflex was incapable of synchronized sound. † â€Å"Filming began in August 17, 1959. Godard met his crew at the Notre Dame cafe near the Hotel de Suede and shot for two hours until he ran out of ideas. Coutard has stated that the film was virtually improvised on the spot, with Godard writing lines of dialogue in an exercise book that no one else was allowed to look at. Godard would give the lines to Belmondo and Seberg while having a few brief rehearsals on scenes involved, then filming them. No permission was received to shoot the filmin its various locations (mainly the side streets and boulevards of Paris) either, adding the spontaneous feel that Godard was aiming for. However all locations were picked out before shooting began and Assistant Director Pierre Rissient has described the shoot very organized. Actor Richard Balducci has stated that shooting days ranged from 15 minutes to 12 hours, depending on how many ideas Godard had that day. Producer Georges de Beauregard wrote a letter to the entire crew complaining about the erratic shooting schedule. Coutard claims that on a day that Godard had called in sick de Beauregard bumped into the director at a cafe and the two got into a fist fight. † â€Å"Godard shot most of the film chronologically, with the exception of the first sequence which was shot towards the end of the shoot. Filming at the Hotel de Suede for the lengthy bedroom scene between Michel and Patricia included minimal crew and no lights. This location was difficult to secure, but Godard was determined to shoot there after having lives at the hotel after returning from South America in the early 1950’s. Instead of renting a dolly with complicated and time- consuming tracks to lay, Godard and Coutard rented a wheelchair for the film that Godard often pushed himself. For certain street scenes Coutard would hide in a postal cart with a hole in it for the lens and stamped packages piled on top of Coutard. Shooting lasted 23 days and ended on September 12, 1959. The final scene where Michel is shot in the street was filmed on the rue Campagne- Premiere in Paris. † It left me hanging where Michel was shoot and Patricai catched up with the detective. Their dialogue had me thinking what was the meaning of their conversation especially the word â€Å"louse†. In my research it means a plural of â€Å"lice†, a wingless usually flattened blood sucking insect parasitic on warm- blooded animals or a person who has a nasty or unethical character underserving of respect. Michel for me is the big â€Å"louse†! Frankly speaking I was not really into the film. The very first time I watched it, it was all in French with no subtitles. I tried myself to be interested with it but I just found myself bored. Good thing our teacher shared a copy with subtitle. Being a student I was diligent in all the dialougues and scenes. I was carefully observing the techniques that I’ve learn in French New Wave. I find it fascinating that during that time, Godard was a young director who was thinking outside the box. I love the confidence and the guts he puts into his film. He was even part of the film. So I tried to know him more. His most influential innovations was to design shots that seem astonishingly flat. He is the most widely imitated director of the entire post war era.

Fret and Regret

Case-1 Fret and Regret 1. Explain in detail using concepts from the course what the problem Ian is faced with. Ian has 2 major problems; he doesnt want to use Iphone 4S instead of Galaxy S2 and he doenst want to broke Molly’s heart. First problem is about his personal taste and desires. Ian thinks that with Galaxy S2 he can benefit from extra technological advantages such as 4g, extra storage and computer remote contrale. This shows that in Ian’s opinion Galaxy S2 has better quality rather than Iphone 4S. Another reason about Ian’s preferance is Galaxy S2 has bigger screen.So in his opinion Galaxy S2 is more succesfull than Iphone about designing. In terms of technology and design Galaxy S2 seems more attractive to Ian. The fact is that these two smart phones both have comparative advantages to each other and price is the same. At this point, personal taste becomes important and that is why Ian prefers Galaxy S2. Second problem is about ethics. Molly bought expen sive, usefull and one of the best smart phones; Iphone 4S to make Ian happy. She sacrifised her money and time in order to give perfect present. So if Ian exchanges the phone that would make her sad and her efforts would be in vain. . Should Ian change the phone or keep the phone? Again use as many concepts from the course as are relevant. Ian’s consumer behaviour depends on; brand, his personality, his girlfriend and technology. According to the case if he only considers brand and technology his choice would be Galaxy S2 for sure. But if he considers all of these points and gathers more information, rational choice would be Iphone 4S. For that reason Ian should keep the phone. He didnt give Iphone 4S enough credit and he admitted that he has distaste for apple products; proof of prejudice.Also Ian didnt do enough market research so he has some wrong informations about Iphone 4S’s technology. You can have computer remote apps and extra storage options unlike Ianâ€℠¢s claims. Before buying new products, awareness, interest, evaluation, trial and adoption should be the process. Ian skipped trial and evaluation parts and only paid attention to interest. While purchasing expensive and to be used for a long time products these steps shouldnt skip. Bigger screen and some extra features directed him to want Galaxy S2. But he also stated that these phones are identical in terms of functionality.Ian realised he needs a phone and briefly searched for Galaxy S2. He was in the second step of the buyer decision process. He should have asked his Iphone 4S and Galaxy S2 user friends, get more information and try Galaxy S2 before making final decision. Since there is no time left for evaluating alternatives, he should keep Iphone 4S and doesnt make sad Molly. If he exchanges the phone he might regret from Galaxy S2 and also broke his girlfriends heart. So instead of taking those risks, he should continue with the phone which he started to get used to.

Cultural Competence in Health Care Professional Practice Essay

Cultural Competence in Health Care Professional Practice - Essay Example Australia is an example of such a country that has experienced cultural diversity which has had immense impact on both professional and personal lives of healthcare professionals, critically affecting service delivery. In order for podiatrists, and indeed all the healthcare professionals in general, to deliver healthcare to the desired levels, cultural diversity should be put into consideration in practice, promoting a culturally safe environment and acquire cultural competence. In basic terms, culture describes an assortment of beliefs and behaviours to which a particular group ascribes and passes on from one generation to another. Adler (2004) defines equity as trait of fairness and impartiality; diversity as an array of various things; and competence as a suitable application of attributes and knowledge through the actions and behaviours of an individual. As such, cultural competence could be defined as the possession of attributes and knowledge that foster understanding of a wide array of beliefs and behaviours of diverse groups of people and applying it equitably. For healthcare professionals, including podiatrists, to attain cultural competence, Betancourt (2002) argues that they would have to exhibit attributes and behaviours that would promote their ability to effectively work with people from diverse cultures. i. Value diversity and accept cultural differences - The element of valuing diversity and accepting cultural differences requires one to keep an open mind to the environment and view each situations without bias. It should be appreciated that in any given environment, each person is different and would therefore have unique values and beliefs. ii. Possess cultural self-assessment capacity and an understanding of own culture – Cultural self-assessment capacity and understanding own culture implies the need to be able to critically comprehend one’s belief system. This requires unbiased approach

English literature - Essay Example The company has over five hundred employees, including well known designers in the region. Mr. Denzel Lawrence is the owner of that clothing line. The C.E.O of the company is Ian Beam. He is a brown and extremely tall Swedish gentleman, in addition to being down to earth. He cooperates well with all employees in that company. He owns a large mansion in New York City, where he lives happily with his cute wife, Diana. On this particular morning, he had several meetings with the designers in the company, to review some of the designs they had created that week. The meetings went extremely well, and Mr Ian was happy with the designs in place. Thus, he gave them a go ahead of putting those designs into clothes. As soon as the last meeting was over, his wife called and said, â€Å"Honey, I hope you are having a fantastic day at work. I just missed you and wished to hear your sexy voice again.† One could tell from the tone of her voice that they were madly in love. At the middle of t heir conversation, his secretary cut him short telling him that the boss, Mr. Denzel, wanted to speak with him. Therefore, he hurriedly wished his wife a fantastic day and rushed to find out what the boss wanted. Apparently, Mr. Denzel was equally a people’s person. He loved cracking jokes here and there to keep his conversations jovial. In addition, he was so in love with statues. His office was covered with a lot of statues of all shapes and sizes. One could think he was worshipping them. Later on in the afternoon, Mr Ian was scheduled to hold another meeting with other investors in the company. However, they called on time to cancel the meeting to the relief of the CEO. Therefore, he decided to take that golden opportunity to rush home early and surprise his wife. On his way home, he stopped near a flower shop to buy a bouquet of roses for his wife. Apparently, he was a frequent customer in that flower shop. This is because he loved giving his wife some flowers each time h e had that opportunity. He drove home smiling all the way, listening to some cool music. All through, he was fantasizing about the happy moments they would spend with his wife that afternoon. He anxiously opened the door to his luxurious mansion and went ahead to the kitchen first to take a cup of water. Surprisingly, he was very anxious to meet his wife that early. He laughed at himself quietly thinking aloud, ‘she is my wife for crying out loud and not a girl I just met and have a crush on hahaha.’ He was madly in love with his wife, so he tried to calm himself down by saying that probably that was the reason behind the anxious feeling he had. Some strange noises in the bedroom cut his thoughts short. He picked up some kitchen knife and tiptoed towards the bedroom. What he saw upon opening the bedroom door almost made him drop dead in disappointment: There was his wife in bed with another man! He thought: â€Å"What the hell? You mean Diana has been cheating on me al l through, and I have never suspected. Oh God, why was I so stupid and blinded by her sweet words?† He closed the door without uttering a single word and left quietly with painful tears on his eyes. On his way out, he saw a key holder with the name of his boss written on it. This made him even more confused. â€Å"Of all other people, why did she have to cheat on me with my own boss? Oh God, I thought my boss was my friend.† He just got into his car and drove carelessly with no direction in his mind. He was just driving to get as far away from his house as

Sampling and Data Collection - Assignment Example A research problem where probability sampling is appropriate is in a study of effects of brand modification on a product’s popularity. The research problem targets a diversified population by such factors as age, income, levels of education, and area of residence. Significance of sub-populations, within the factors, may further vary and a representative sample that also factors relative significance of the sub-populations requires a stratified random sampling approach. The population is in the case divided into the subgroups and each group allocated a probability of sampling a participant. Random sampling is a method of obtaining a sample, based on unrestricted probability sampling approach, while random selection is an approach to allocating sampled research participants to different groups in a study (Black, 1999; Christensen, Johnson, and Turner, 2011). Random assignment is important in experimental research situations in which participants are to be assigned to treatment and control

Analysis - Case Study Example The problem occurred because of a combination of issues, which range from managerial to personal experiences. First, the team leader failed to understand that his team had differing abilities and that he had more experience than the rest. His misunderstanding resulted in him setting almost unrealistic goals. He wanted the team to attain their objective at a pace that was not comfortable for all the members. He considerably had more experience because he had worked in the field longer than the rest of the members. During their working period, there are instances of lack of cohesion in the team, which resulted in one of the team members feeling less motivated to remain a member of the team. At the project completion, some of the members quit the company and signified their demotivation to work. The type of conflict was a relation conflict because it involved Parker holding prejudiced opinion of Millar. An analysis of the case reveals that Parker combined a number of leadership theories. His appointment to the leadership role was on a basis of competence, and not leadership qualities. The company, as a result, used the competence model during his selection to project the manager position (McShane & Steen 1995). He only failed to fulfill one out of the eight leadership competencies, which is emotional intelligence. Despite his cognitive and practical intelligence, knowledge of the duty, leadership motivation, integrity, and the rest, he failed to motivate Millar. Parker found himself yelling at Millar for upon realizing that he was slowing down the group. Parker proved a limitation of the competency model that leadership is within the person and not their relations with others. Parker failed to focus on the people-oriented behaviors by, not showing concern for the welfare of the employees. He only focused on the task-oriented behaviors by expecting the workers to

Further, it refers to the act or practice of being hospitable, that is, the reception and entertainment of guests, visitors, or strangers, with liberality and goodwill. To dispense our generous warm welcome and comfort ability we need adequate infrastructural support that helps to maintain sanitation, hygienist and safety of the precinct. Hospitality frequently refers to the hospitality industry jobs for hotels, restaurants, casinos, catering, resorts, clubs and any other service position that deals with tourists. As an Executive Housekeeper, I would like to forward my professional views in the development of the interiors and exteriors of the proposed extensions of the new floors in the resort. As our resort is located in the moderate climate, the weather being sub tropical with warm summer and mild winters it is highly recommended to have wide ventilation in order to receive adequate sunshine in the arcades. Moreover, since most of our customers have keen interests in the aquatic sports in the ocean in the precinct, I recommend cane furniture on the first floor to shelter the guests during winter for recreation. The resort estate has two large swimming pools and the guests practice many water-sports at the nearby oceanfront. As a result, people staying at the resort often go to the front desk and concierge areas dripping water from their wet bath suits. Sometimes they even go to the coffee shop counter in wet bathing suits. In order to meet the adverse effect of the movements of the guest it is highly advisable to have carpet floorings to prevent the floor from moist as well as to prevent the guests to fall victim of accidents to slip on the mosaic floor. FLOORING SPECIFICATION Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Often used to mean parquetry wood flooring, it can also refer to various other materials like carpet or linoleum. structural and aesthetic considerations should be entirely subject to functionality to meet with both popularity and skepticism, it had the effect of introducing the concept of functional perception and enjoyment of a building, not only practical but also aesthetic, psychological and cultural.

Spectrum Sensing and Spectrum Sensing Techniques

Spectrum Sensing and Spectrum Sensing Techniques Chapter 1.Introduction In recent years there has been an enormous growth in wireless communication devices and wireless users. The ever increasing demand for higher speed and reliability made researchers think about intelligent radios like Cognitive Radios (CR). But major amount of spectrum is available for licensed users. There are various communication bodies like the International Telecommunication Union (ITU), European Conference of Postal and Telecommunications Administrations (CEPT) also European Telecommunications Standards Institute (ETSI) who works on standards of communication that defines the use of spectrum for licensed and unlicensed users. 1.1 Background Spectrum is a valuable resource in communication. Over the past few years as the use of various wireless technology is increasing rapidly so we either need more spectrum or make efficient use of current spectrum to satisfy their needs. One way of making efficient use of spectrum is employing spectrum sharing technique. There are many spectrum sharing techniques available like energy detection, cyclostationary feature detector, and matched filter. Of the above technique matched filter and cyclostationary gives more accurate result but they are bit complex and computationally harder as compared to energy detection technique. Energy detection is the simplest of above three and computationally less complex. 1.2 Motivation Survey has shown that at any given time only portion of spectrum is utilized. According to a report published by FCC (Federal Communications Commission America) in 2003 has set a set of rule for efficient use of spectrum for licensed and unlicensed users. Also OFCOM (Office of Communications United Kingdom) has noticed the underutilization of spectrum. At any given time only portion of spectrum is utilized. Even if the system says there are no frequencies available, there is still some frequency available. These available frequencies are known as spectrum holes or white spaces. Some of the bands are completely occupied by users while some bands go unutilized. And that is inefficient use of spectrum. We must have noticed that in cases of emergencies like the train bomb blast in July 2006 in Mumbai, India cellular network actually failed to support huge amount of customer at the same time, this was also the case during 9/11 in USA. If we were having cognitive radios at that time peop les would have been able to talk to their families and inform about their safety. As we are moving from 3G (Third generation) to 4G (Fourth Generation) we need to make certain changes in our wireless technologies. Below shown is the measurement of 0 GHz to 6 GHz at Berkley Wireless Research Center (BWRC). 1.3 Aim and Objective This thesis emphasises on understanding Cognitive radios, the importance of spectrum sensing for todays world, the issues regarding the same. A simplified Matlab code is used to support our thesis. As the thesis follows you will find more about cognitive radios and spectrum sensing with a technique to generate white space at a specific frequency. The main objective of the thesis is to do survey on spectrum sensing and spectrum sensing techniques. Then do plan a model for the same. A model can be supported by a Matlab code. And after all this we need to analyse the model we suggested and further improvements that can be done in that. 1.4 Thesis Organisation Our thesis is organised as follows: Chapter.2 Literature Review This chapter begins with a brief history about cognitive radios .Which is followed by a detail explanation of Cognitive radios and spectrum sensing and some of the spectrum sensing techniques used. At the end of this chapter a business model for spectrum sensing and multi resolution of CR is given. Chapter.3 System Description This chapter basically deals with sampling and its importance to us. Also you will find technique to get your spectrum at specific center frequency under â€Å"generation of White Spaces†. Chapter.4 Simulation/Design Analysis As the name suggests, this chapter deals with simulation model and detail explanation of the code used for spectrum sensing using energy detection. In this chapter we have shown the output of the simulation used. Chapter.6 Future Work This chapter suggests some of the future work to be done with this thesis which could be useful for further research in this field. Chapter.7 Conclusion This gives the concluding part of the thesis. Chapter 2 Literature Review In this chapter we are going to discuss about the cognitive radios, like what are they and why are they so important to us. The chapter begins with a short history of cognitive radios, which is followed by a general discussion on OFDM, some of the challenges faced by cognitive radios in real environment, and also some of the applications of cognitive radios. We have tried to explain spectrum sensing in brief and the techniques used for spectrum sensing in todays world. Finally a business model for spectrum sensing is showed which is preceded by multi-resolution of Cognitive radios. 2.1 History of cognitive radios Dr. Joseph Mitola III was the first to introduce or propose the theory of Cognitive radios in 1999. According to Dr. Joseph Mitola Cognitive radios will be the radios that are smart and intelligent enough to find the available bandwidth in a spectrum. It will also have knowledge of right information that has to be passed to the user. And user does not have to take some extra effort for that. It is supposed to do this automatically. He has also mentioned in his PhD dissertation that CR is natural extensions of software defined radios. In 2002 the FCC published a report prepared by Spectrum Policy Task Force [SPTF] which says that majority of spectrum is underutilized. And there is actually is not shortage of spectrum but rather we need to make efficient use of the current spectrum. Also in same year 2002 Professor Cave from UK presented a report which speaks of the possibility of selling bandwidth to the user depending on their requirement. But it would not be fair to give unlicensed user allow to use licensed spectrum. So in December 2002 FCC issued a Notice of Enquiry (NOI) to see TV channel bands can be made available to unlicensed users. Then in 2003 FCC forms a set of rules and proposed interference temperature model for keep track of interference. Later in the same year Notice of Proposed Rulemaking (NPRM) tried to see into issues related to cognitive radio technology where it also pointed out Cognitive radios is a advanced technology which could help efficient use of spectrum by licensed users in own network and by sharing spectrum and with unlicensed users by negotiating when required. This encouraged many researchers in the field of cognitive radios. Major progress in cognitive radios took place in the year 2004, where FCC published NRPM which showed possibility of allowing secondary users to use licensed spectrum. FCC opened three bands for unlicensed users which are 6525 to 6700 MHz, 12.75 to 13.15 GHz and 13.2125-13.25 GHz. This allowed cognitive dev ices to transmit six times more. Also IEEE standards are working parallel to the FCCs. Spectrum pooling system by Professor Timo A Weiss from Karlsruhe University Germany), OFDM based Cognitive radios by professor Ian F Akyildiz et al from GIT (USA) are some of the promising works in Cognitive radios. there are many researches are done, many still going on in Europe, Asia, and America, exploring various aspects of cognitive radios. In Jan 2010 first call over a CR network was made in university of Oulu using CRAMNET (Cognitive Radio Assisted Mobile Ad Hoc Network). 2.2 Cognitive radio With the development of wireless communication devices and technologies in WLAN and WAN spectrum is becoming scarcer. Low frequency bands which are near few GHz are very scarce and highly congested. In current wireless system we are using fixed spectrum allocation scheme. In fixed spectrum allocation scheme a part of spectrum is owned by an operator. Unlicensed users are not allowed to use that spectrum. This leads to the problem of spectrum scarcity. Survey has shown that more than 50% of the spectrum is underutilized. This is where Cognitive Radio (CR) is comes into picture. CR is introduced to solve the problem of spectrum sharing. Cognitive Radios actually scans the spectrum and during scanning it looks for spectrum holes. The main objective of the cognitive radios is to look for opportunities or white spaces in spectrum band as quickly and as much as possible. And when we say opportunity, opportunity could be in time or frequency domain. Also when we locate this spectrum holes opportunistically we also need to vacant the occupied spectrum as soon as primary user comes back. Here primary user means the users whose spectrum we are using (licensed user) and secondary means the unlicensed users. Cognitive radio is a pattern for wireless communication technology in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. These altered parameters are associated with the active monitoring of several factors in the external and internal radio environment e.g. radio frequency spectrum, user behaviour. Cognitive radio can be said as next generation of software defined radio (SDR). They are flexible in terms of their transmission characteristics in terms of frequency, bandwidth, ISP which makes smart decisions to configure the SDR at any point in time to achieve a particular goal. By combining these two technologies makes a radio intelligent and flexible and which helps to adapt it to the variations in the environment, user requirements as per the other radio users. Adaptation to changes and requirements should lead to highly reliable communication whenever and wherever required, while making efficient use of spectrum. Good cognitive radio uses analysis done for long period to know about the environment and also his own behaviour. There are various parameters taken into account to decide transmission and reception changes, we can distinguish certain types of cognitive radio. The main two are as follow: Full Cognitive Radio : It is also known as Mitola radio in which every possible parameter which can be observed by a wireless node is taken into consideration to take decision Spectrum Sensing Cognitive Radio: It is the type in which only the radio frequency spectrum is considered. And Depending on the parts of the spectrum available for cognitive radio, we can distinguish as: Licensed Band Cognitive Radio: It is the type in which cognitive radio is capable of using bands assigned to licensed users, apart from unlicensed bands, such as U-NII band or ISM band. Unlicensed Band Cognitive Radio: This can only utilize unlicensed parts of radio frequency spectrum only or the bands which are free to use. 2.3 About OFDM OFDM stands for Orthogonal Frequency Division Multiplexing. It is generally a type of Frequency Division Multiplexing (FDM) rather a special case in FDM. What makes it special is its orthogonal behaviour. Now the word orthogonal basically means mutually independence. When we say A is orthogonal to B, we mean that A has no vector in direction of B and vice versa or in other words A and B is mutually independent. Or the integral of two signals over one period is 0. In OFDM a single signal is first multiplexed and modulated independently to create orthogonal signals. This means the signal is first divided into number of smaller streams and then modulated further before transmission. For example imagine a slicing of cheese and grilling or cheese. Slicing is like FDM where whole data is sent in a bunch and grilling is like OFDM where the data to be sent is first divided into smaller data and then processed to transmit further like OFDM. Figure shown below is one more way to understand the concept of OFDM. On the left hand side is a big container which carry whole bunch of data at one time and take it to the destination. And on right hand side is four smaller containers where each carry smaller portion of data and take it to the destination. These smaller containers can be assumed as sub-carriers. And in case of OFDM they are orthogonal sub-carriers. The main advantage over here is that even if some of the cheese is lost during grilling, still we have not lost all the cheese. In OFDM input data with high data rate is first passed thorough serial to parallel converter. This parallel divided data is then modulated on individually. And parallel to serial conversion is done before transmission. This parallel divided data is our sub-carriers. These sub-carriers must be orthogonal. 2.4 Cognition cycle Above figure shows the rough model of Cognition Cycle. It reads the surrounding environment and makes decision accordingly. When we say decision we mean cognitive radio sense the requirement or urgency that may be in terms of changing a channel or churning from one technology to another depending upon the scenario. There are different stages where it observes the environment, learns it and then plans its action make required decision and then execute its plans. It is much like a radio with a power of thinking which was not been able before. The figure below shows the cognitive radio architecture suggested by Dr. Mitola. 2.4.1 Some important terms 2.4.1.1Wireless Environment/Outside world- It refers to a communication environment that includes any communication devices and the frequency bands they are working in. 2.4.1.2 Spectrum sensing- It is the technique used by cognitive radios to sense the spectrum. This action involves finding availability of white spaces or spectrum holes in the spectrum. 2.4.1.3 Spectrum Management- It involves catching the best spectrum available so as to satisfy user communication requirements. Cognitive radios should decide on the best spectrum band so that it can meet the Quality of service required for all available frequency bands, therefore these functions are necessary for Cognitive radios. These management functions can be classified as: Spectrum analysis Spectrum decision Spectrum Mobility: It is defined as the process when a cognitive radio device exchanges its frequency of operation. Cognitive radio networks target to use the spectrum in a dynamic manner by allowing the radio terminals to operate in the best available frequency band, maintaining seamless communication requirements during the transition to better spectrum. Spectrum Sharing: providing the fair spectrum scheduling method. One of the major challenges in open spectrum usage is the spectrum sharing. It can be regarded to be similar to generic media access control MAC problems in existing systems 2.5Cognitive Radio Challenges Three main problems experienced by CR are as follows: Interference (Mainly because of Hidden Nodes). Security. Control. They are described as follows: 2.5.1 Interference and the Hidden Node Problem Ideally while designing a CR we should consider that it does not have any impact on existing radio users, but in practically some impact is expected. If a particular user have non-cognitive radios, it is essential to study and make a note that how they would be affected by the interference of CR, mainly with respect to sharing resources such as spectrum, time, space etc. CR adaptive nature could be difficult to predict and thus making it hard to control the behaviour of a CR which will concern for user who faces CR interference issue. In communication industry the main concern about CR is the hidden node problem. This scenario arises when a CR is not capable to detect an interference with any of non-cognitive radios within its range, not only because of CRs own spectrum sensing is ineffective but also due to some non-cognitive radios are hidden. For example, if a transmitting contemporary user is not in the range from the CR, its transmission power may not be strong enough at the CRs location, it may be reduce than the noise floor which makes it more difficult to get detected. As the CR might not be able to detect a transmission by a contemporary user and similarly unaware of availability of the receiving by a contemporary user. Consequently, if it is confirmed as safe to use the contemporary users frequency and CR starts transmitting, at the contemporary receiving end it will create interference. The CR may have a limited view of spectrum provided from wide spectrum measurements which may cause interference with the receiving user. The localised spectrum view denotes that a CR should be potential to find transmitting user those are communicating below the noise level, since the strength of the received signal is very weak at the CRs location. Similarly a situation can occur where the signal attenuate by distance, thus user transmission is blocked by obstacles such as buildings, towers, hills or mountains. For example consider a CR in a valley would have a limi ted picture of the surrounding radio environment, as compared to that if it were located on top of a hill. 2.5.2 Security Concerns CR may be vulnerable to malicious effect, resulting into unexpected or problematic behaviour of individual CRs or complete networks. This problem springs up from the potential to re-program CRs in an unauthorized way. Hacking or placing a vulnerable code, virus on a network might enable criminals to steal valuable information from a CR through electronically, fool a network operator into charging others for services or achieve potentially widespread denial-of-service. A considerable amount of regulatory work will require to be done to clarify who would be responsible for the various security areas of CR, software developers, manufacturers, network operators and CR users themselves may all have a role to play. The CR security issue is closely related to that of SDR, which already discussed and hence not repeated here. Instead, a brief summary of the issues is given. Downloading software updates over an air interface poses some specific problems for security. Several digital signatures will be required for each piece of downloaded software in order to meet likely regulatory requirements. Exactly who is necessary to authorize software downloads must be standardized before any large scale deployment of over-the-air updates can be realized. 2.5.3 Burden of Control and Regulatory challenges A CR in reality will have some effect on different spectrum users the compliance of these new radios is likely to focus on a Policy module defined within a CR, which will determine the boundaries of CR behaviour. It is important while studying CR; to consider how users would not be affected by interference from CR devices and the exact operation and nature of a proposed CR policy system must be understood carefully. It is likely to include a detail case study of the specifications and characteristics of all the contemporary users for a specific CR or complete network of CRs may share the resources. The effort in controlling CR devices, it is necessary to ensure their behaviour is properly or not, even in the case of faulty or tampered devices, that measures are quickly implemented to intense problems. This will involve policies and standards which are created in a universal digitally interpretable policy, so that all CRs can understand the same. Monitoring techniques and powerful alg orithms are required to enable detection and identification of bad CRs and in this way it provides traceability to find or determine who is responsible for the issue. In addition to these challenges, spectrum regulators and spectrum managers will require providing access to licensed spectrum in such a way that is traceable, transparent and highly dynamic. If CRs are allowed to cover international territory additional effort will be required, due to the necessity to provide and collaborate cooperation with other countries. Assuming that acceptable control of CR policy behaviour is technically possible and feasible, it may turn out to be such a great burden that it will be simply not economically viable and the benefits of CR are outweighed by this burden. 2.6 Important Applications for Cognitive Radio are Downloading of audio and video files on mobile handsets. This application requires moderate data rates and near-ubiquitous coverage. Emergency services communications: It requires interoperability and a moderate data rate with local coverage. Broadband wireless networking: Very high data rate required but CR users have option to accept limited coverage, e.g. hot spots. Multimedia wireless and sensor networking: Broad range of data rates may be required. 2.7 Spectrum Sensing Spectrum sensing is the process performing measurements on the part of spectrum and on the basis of measured data making a decision related spectrum usage. As the requirement and quantity of users is getting increased day by day, it is necessary for ISPs to have large amount of spectrum in order to achieve the QOS (Quality of Service). This leads the interest in unlicensed spectrum access and spectrum sensing is vital concept of this. In a situation where there are licensed user and any unlicensed exists, licensed user (primary user) is to be protected and no unlicensed user can interfere any licensed users operation and such cases Spectrum sensing is also useful to detect the existence or non existence of a primary user. Spectrum sensing is an important concept for exploring spectrum opportunities for the secondary spectrum usage in real-time. It detects the unused spectrum and shares it without any noticeable interference with other users. It is an important requirement of the Cogn itive Radio in order to sense spectrum holes. Detecting primary users is the most efficient way to detect spectrum holes. 2.8 Spectrum Sensing Techniques Available Spectrum sensing plays a vital role in cognitive radios. And the type of spectrum sensing techniques to choose more or less depends upon the spectrum sensing technique. A method such as energy detection proves to be one of the simplest of all, but it doesnt works well at low SNR, varying noise levels, fading. On the other hand technique such as Matched filters shows better performance, but they comes complex receiver design. We are going to discuss some of these techniques as we proceed further. 2.8.1 Matched Filter Technique This is the technique which takes minimum amount of sensing time. In this method of spectrum detection, receiver receives a pilot signal along with the data that is sent by the transmitter. A pilot signal is a single frequency that is used for synchronisation. All the secondarys those are struggling for spectrum should have knowledge of this pilot signal. There should` be tight timing synchronisation between primary and secondary. They are also required to know about the kind of modulation being used, pulse shaping. Also secondarys must have another receiver for every primary. This kind of techniques also fails when there is frequency offset. Examples of this technique are TV signals, CDMA with pilot, also used in OFDM. 2.8.2 Energy Detection technique This is the most simples of all techniques. In this the receiver has no knowledge of the transmitted signal. The receivers need not to have knowledge about the modulation type or any kind of pilot signal. Earlier energy detection was done with the help of a LPF (Low Pass Filter), Digital to Analog converter (D/A), and square law device that used to calculate the energy of the signal. Later it is done by making use of fast Fourier transform (FFT). This is known as periodogram method in energy detection. 2.8.2 Cyclostationary Feature Detection Signals are modulated with sine waves or cyclic prefix as in OFDM. And they are periodic. This periodic property of a signal helps it to be cyclostationary. This technique basically uses this principle of spectral correlation to detect the spectrum. Even if signals have similar PSD (Power Spectral Density) but they have do not have similar spectral correlation. 2.9 Multi-resolution for Cognitive Radio Sensing The concept of multi-resolution for Cognitive Radio can be applied with different methods but, the basic idea is the same. The whole spectrum is first sensed by using a coarse resolution. After this first step fine resolution sensing is done on a part of interested bands. In this way CR avoids itself from sensing the spectrum at one time and thus saving time and power. In this way, the sensing time is reduced and the power also been saved from unrequited computations. Also the multiple antenna architecture helps parallel processing and enables to reduce the sensing time. But, it increases the chip area and consumption of power which is not desirable. Also for coarse resolution sensing the mixer has to produce many frequencies and Also it should switch to one frequency for beginning the fine resolution sensing. If the signal is low pass signal then we can use fine resolution to scan the whole spectrum. Because low pass signal has low center frequencies and its sampling is doable. But for pass band signals it is not feasible to scan the whole spectrum. Because, for example say if we have some signal with center frequency of 850 MHz, it is not practically possible to do sample that signal. As according to Nyquist theorem sampling rate should be at least twice that of center frequency. Therefore it is practically not possible to sample a signal at 1600 Mega Hertz. 2.10 Business Model for Spectrum Sensing So far we have discussed about Cognitive radios and spectrum sensing in details. Since this is telecom, and telecom involves huge capital investment. One of the most costly things in telecom is getting the license itself and then comes the infrastructure and installations etc. Currently most of countries work on static spectrum allocation basis. For spectrum sensing to work we need some kind of regulation or set of rules that all will be ready to work with. A team from Brussels University has suggested a model for the same. The same model is discussed in brief below. This model is divided into four main categories. i. Ownership- Ownership simply means the ownership of license. One who has license is authorized to use particular band of spectrum. And if another licensee wants to share a spectrum then it will depends on parameters discussed below. If the operator is unlicensed then there is now issue of ownership. ii. Exclusivity- Exclusivity means whether or not a particular operator is exclusively assigned a band of spectrum. That will be issue of regulator to decide to exclusively assign a spectrum to a specific user. If it is assigned exclusively then nobody can access that band of frequency, and if not then those bands of frequencies will be available for sharing. iii. Tradability- Tradability means whether or not a terminal is allowed to switch between frequencies from different operators. If tradability is permitted frequency band or bands can be auctioned for sale or given on lease. iv. Neutrality- It is possible that some of frequency bands can be accessed by number of RATs (radio Access Technology) or may be limited to a particular RAT. If frequency bands are not available to number of RATs then that band need to address more issues, such as setting technical conditions to access the band and coordinating the cooperation between multiple technologies. Unlicensed: Unlicensed deals with the band of frequencies which are free to use, like ISM band. Common example for this is Wi-Fi which operates in 2.4GHz. This band of frequency is available to all and there is special condition to access this band. Single RAT Pool: This pool is related to a group of licensees which are not exclusively assigned any band of frequency and using same RAT. Multi RAT Pool: It is similar to Single RAT Pool except that it has multiple RATs. Single RAT Market: In this each operator is assigned with a separate frequency, but that can be accessed by the conditionally secondarys. Multi RAT Market: In this the operator is a licensee and is exclusively assigned with a band of frequency, and also with tradability. Flexible Operator and Static Spectrum: If a particular band of spectrum is exclusively assigned to an operator and without tradability. And if there is only one RAT, then it is known as Static Spectrum else Flexible Operator. 2.11 Survey outcome As per the literature review we concludes to use Energy detection technique for spectrum sensing as it is the fastest spectrum detection technique available and also it is simpler as compared to other techniques. There are many researches done in this field and many are still doing. Because of the survey we get knowledge about various techniques available in market. This led us to do a simulation model with one of the spectrum sensing technique. Now as far as selection of spectrum sensing technique is concerned, we selected Energy detection technique. The same could be seen in next part of the thesis which includes its design and implementation in simulation model. Chapter 3 Simulation Design 3.1 Sampling and Its Importance Sampling is a process of converting the continuous analog signal to a discreet analog signal and the samples signal is the discreet time representation of the original signal. If the message is coming from a digital source, then it is in the form to be processed by digital communication systems. But in real life not every signal is digital, message signal can be analog. In situation like these, we have to first convert the analog signal into discreet time signal, this is sampling. For this process to work well, sampling rate should be selected carefully or in other words it should satisfy Nyquist criterion. And Nyquist Criterion says that the sampling frequency should be at least twice the maximum frequency in signal. Fs ≠¥ 2fmax or T=1/ fmax Where â€Å"Fs† is sampling frequency, fmax is maximum frequency in the signal. T=Sampling period. Sampling is like reading a signal in analog form and taking its value at that instant of time. So more the samples we take better the resolution of the signal and, signal can be recovered more accurately. But if we take less number of samples, then resolution of the signal decreases. If we go on reducing the sampling rate, then times comes when it is difficult to recover the original signal from the sampled signal or in other words original information in the signal is lost. This is also known as aliasing. Aliasing is the effect which takes place if the signal is sampled less than twice the maximum frequency. 3.2 Types of Signal 3.2.1 Time limited signal- It is a signal which exists for only certain duration of time. Out of this duration, signal does not exist. A rectangular pulse of duration â€Å"T† seconds can be considered as time limited signal. x(t)=A †¦ for 0 3.2.2 Band Limited signals- It is a signal which has a frequency spectrum which exists only over a certain range of frequency. The value of signal outside this range of frequency is zero. Mod(X(f))=A †¦.-B 3.3 Sampling Of Low pass and Band Pass signal Low pass sampling theorem states that- a) A band limited signal of finite energy, which has no frequency components higher than W Hertz, is c

College Admissions Essay - The Search for Truth :: College Admissions Essays

College Admissions Essay - The Search for Truth    Whoever said that we were supposed to take everything on faith? Not God, that's for certain. He's always told us to try it for ourselves, and see if it makes our lives better. I'll never forget the day my high school chemistry teacher had a nervous breakdown because he tried to understand a universe where there was no God, whatsoever. (That is true, to my knowledge, by the way.)    I've always been surprised how much faith people put in science, though. Many of the greatest scientists believed in God, and my speculation as to why, is that those scientists knew just how amazing it was that they could discover an equation to measure gravity, or one that made energy and matter that same. People, of course, had no idea what they had on their hands and worship it today as if it were God. Those scientists knew very well, after all their work, that any theory they produced was only awaiting its demise. The values that when put to the test, would prove it wrong. And then they'd find their mistake and fix it.    People have made something of a religion out of science these days. People treat it as a burden, rather than the enlightenment it is, but they also treat those far advanced in it, as infallible and beyond mortal ken. Not so bad as the inquisition days, believe you me! But the Inquisition really only went underground, to explode again as science, this time trying to kill faith instead of logic. Luckily, the new inquisition only condemns people to a life of fear and hate, instead of religious bigotry, or even real religion, like being nice.

Embryonic Stem-cell Research - A True Faustian Bargain :: Argumentative Persuasive Topics

Embryonic Stem-cell Research - A True Faustian Bargain      Ã‚  Ã‚   In the debate over whether the federal government should fund embryonic stem-cell research (ESCR), our country is being offered a true Faustian bargain. In return for a hoped-for potential - it is no more than that - of deriving desperately desired medical breakthroughs in the treatment of such afflictions as Parkinson's disease, paraplegia, and diabetes, we are being asked to give the nation's imprimatur to reducing human life into a mere natural resource to be exploited and commodified.    Given the stakes, our lawmakers owe it to their country to take the time to thoroughly understand the issue before speaking in public and taking sides. Unfortunately, some senator's statements in favor of embryonic research exhibited stunning ignorance regarding the subject about which they opined. Making matters worse, the press quickly leaped upon the statements of these pro-life senators as proof that embryonic research is moral, ethical, and scientifically justified, when the reverse is actually true.    Senator Hatch's attempt to explain his pro ESCR funding position to Chris Matthews on Hardball on June 20, demonstrated that he doesn't know an embryo from a stem cell. Take the following statements:    * "After a long period of study and prayer, I found that pluripotent cells are not full human beings but can be very, very beneficial as used by science to help with all kinds of maladies...." * "It is appropriate to use pluripotent cells but inappropriate to use totipotent cells because a pluripotent cell cannot be made into a full human being. A totipotent cell can actually be replicated into a human being through even cloning." (Totipotent cells are the first to appear after fertilization and can actually develop into a completely new embryo - as occurs during identical twinning. Pluripotent [stem] cells appear a bit later. They are "undifferentiated cells" that can develop into any body part - which is why researchers wish to study them.) * "Life begins in the mother's womb, not in a refrigerator."(Embryonic)    In stating that the feds should fund the study of pluripotent cells but not totipotent cells, Senator Hatch confused several essential points. First, pluripotent cells and totipotent cells are not the same thing as the embryo itself. Rather, these cells are constituent parts of the embryonic whole just as vital organs are parts of born persons.

Three Arthurian Misfits of Gawain and the Green Knight :: Essays Papers

Three Arthurian Misfits of Gawain and the Green Knight "Hevys hys handys one heghte, and to the hevene lokes: 'Qwhythene hade Dryghttyne destaynede at his dere wille That he hade demyd me todaye to dy for yow alle.'" p. 264 Awholly determined and brave commitment, mouthed by a gracious king. The Gawain poet, however approaches Arthur much differently in his tale. In stanza five, he describes the hot-blooded nature of the king, who makes rash demands as a rule before eating. Stanza twelve shows us a king who is overwhelmed in speech by the Green Knight, and who seems to have ignored the challenger's statement of peace completely. Finally, the court is utterly ridiculed, to a point at which Arthur accepts the challenge rashly in stanza fifteen, akin to a child taking a swing at another after so much urging. The usual grace and courtesy with which King Arthur is usually endowed is clearly subverted by these stanzas in Gawain and the Green Knight, seemingly to no purpose other than comedy. Here we shall discuss the elements of the three stanzas described above, with their uncharacterisitic treatment of Arthur, and take a deeper look into their purpose within the poem. Stanza five elaborates on Arthur's desire to hear a marvelous tale before he joins in the feast. He appears to stand - "He stightles stif in stalle;" (104) he is not seated at the head of the feasting table, next to Guinevere as he should be. Instead, he is ready to listen to a tale "Of alderes, of armes, of other aventurus;" (95) or joust with a challenging knight - with the risk of losing his life. The wish of the king for deadly sport seems inappropriate in the Christmas setting of the poem, possibly even irreverent in light of the religious aspects of the holiday. Though the king's demands are childish or "child-gered" (86), he sets the scene for the appearance of the Green Knight, which effectively fulfills the request as Arthur "that aventure byholdes" (250) in stanza twelve. The impression of Arthur delivered by the poet is not a dauntless, seasoned leader, but an impatient, belligerent boy. We already know of his strange pre-dining antics, and we are also told that, "His lif liked hym lyght, he lovied the lasse | Auther too longe lye or too longe sitte," (87-88). He is too restless to stay lying or sitting for long, and thus he stands at the the end of the stanza.

Objectivist Epistemology and Ayn Rand Essay

The starting point of Objectivist Epistemology is the principle, presented by Rand as a direct consequence of the metaphysical axiom that â€Å"Existence is Identity,† that Knowledge is Identification. Objectivist epistemology[9] studies how one can translate perception, i. e. , awareness acquired through the senses, into valid concepts that actually identify the facts of reality. Objectivism states that by the method of reason man can gain knowledge (identification of the facts of reality) and rejects philosophical skepticism. Objectivism also rejects faith and â€Å"feeling† as means of attaining knowledge. Although Rand acknowledged the importance of emotion in humans, she maintained that the existence of emotion was part of our reality, not a separate means of achieving awareness of reality. Rand was neither a classical empiricist (like Hume or the logical positivists) nor a classical rationalist (like Plato, Descartes, or Frege). She disagreed with the empiricists mainly in that she considered perception to be simply sensation extended over time, limiting the scope of perception to automatic, pre-cognitive awareness. Thus, she categorized so-called â€Å"perceptual illusions† as errors in cognitive interpretation due to complexity of perceptual data. She held that objective identification of the values of attributes of existents is obtained by measurement, broadly defined as procedures whose perceptual component, the comparison of the attribute’s value to a standard, is so simple that an error in the resulting identification is not possible given a focused mind. Therefore, according to Rand, knowledge obtained by measurement (the fact that an entity has the measured attribute, and the value of this attribute relative to the standard) is â€Å"contextually certain. † Ayn Rand’s most distinctive contribution in epistemology is her theory that concepts are properly formed by measurement omission. Objectivism distinguishes valid concepts from poorly formed concepts, which Rand calls â€Å"anti-concepts. † While we can know that something exists by perception, we can only identify what exists by measurement and logic, which are necessary to turn percepts into valid concepts. Procedural logic (defined by Rand as â€Å"the art of non-contradictory identification†) specifies that a valid concept is formed by omitting the variable measurements of the values of corresponding attributes of a set of instances or units, but keeping the list of shared attributes – a template with measurements omitted – as the criterion of membership in the conceptual class. When the fact that a unit has all the attributes on this list has been verified by measurement, then that unit is known with contextual certainty to be a unit of the given concept. [9] Because a concept is only known to be valid within the range of the measurements by which it was validated, it is an error to assume that a concept is valid outside this range, which is its (contextual) scope. It is also an error to assume that a proposition is known to be valid outside the scope of its concepts, or that the conclusion of a syllogism is known to be valid outside the scope of its premises. Rand ascribed scope violation errors in logic to epistemological intrinsicism. [9][4] Rand did not consider the analytic-synthetic distinction, including the view that there are â€Å"truths in virtue of meaning,† or that â€Å"necessary truths† and mathematical truths are best understood as â€Å"truths in virtue of meaning,† to have merit. She similarly denied the existence of a priori knowledge. Rand also considered her ideas distinct from foundationalism, naive realism about perception like Aristotle, or representationalism (i. e. , an indirect realist who believes in a â€Å"veil of ideas†) like Descartes or Locke. Objectivist epistemology, like most other philosophical branches of Objectivism, was first presented by Rand in Atlas Shrugged. [5] It is more fully developed in Rand’s 1967 Introduction to Objectivist Epistemology. [9] Rand considered her epistemology and its basis in reason so central to her philosophy that she remarked, â€Å"I am not primarily an advocate of capitalism, but of egoism; and I am not primarily an advocate of egoism, but of reason. If one recognizes the supremacy of reason and applies it consistently, all the rest follows. â€Å"

Pakistan and India over Kashmir Essay

Conflicts between Pakistan and India over Kashmir as well as China over Tibet have been around for decades. Although these conflicts are religion based, this is no longer the case since they currently fight over land control (Stokes, 2010). Whereas India and Pakistan is ever fighting to be in control of Kashmir, this case is the same when it comes to China’s conflict for Tibet. Although Tibet is part of China, it considers itself a nation since it has always been bound by religion, culture as well as linguistics and genetic ties (Stokes, 2010). The study aims to address the religion conflicts existing between China over Tibet as well as India and Pakistan over Kashmir. Pakistan and India over Kashmir According to Hajni (2008), Pakistan was founded after the end of the British rule when the Indian Muslims developed the desire to own an Islamic state. Indian Muslims were the Minority religion and this made them feel insecure. Since they were the minority religion, the Indian Muslims were afraid of losing political representation in addition to maintaining their freedom as well as cultural norms. According to Hajni (2008), regarding the criteria for deciding which of the two dominions a state should join; he quotes Lord Mountbatten who said, â€Å"†¦geographic situation and communal interests and so forth will be factors to be considered†¦Ã¢â‚¬  At the time of partitioning, Jammu and Kashmir was predominantly Muslim. However, Hindu Maharaja Hari Singh who supported the annexation of Kashmir by India ruled the state. According to James and Ozdamar (2005), when the British divided the two states, Kashmir was given the option of joining either one. However, through Maharajah Singh, the current leader of that time, Kashmir opted to become independent. Pakistan and India were not happy with this decision since they started forcing Kashmir to join them. It is due to these debates that later resulted to the outbreak of conflicts between India and Pakistan over Kashmir. Pakistani Muslims initiated insurgent type operations to undermine an annexation by India, which further compelled the Hindu leader to align with India to secure military support to counter the Muslims. According to Hajni (2008), India started by laying claim on Kashmir due to the instrument of accession that was signed by Maharaja in 1947. It is because of this move that prompted Pakistan to follow suit. Just like India, Pakistan also laid claimed to own Kashmir since most of its population were Muslims. This gradually escalated into disputes over Jammu and Kashmir, which is still rife to date. The disputes were quite severe since they escalated into wars in a move to acquire the disputed state. Although religion was the main source of conflict between the three nations, it was primarily triggered by the urge for territorial control. China over Tibet Apart from India and Pakistan, another famous religion conflict is that of China and Tibet. Tibet has been practicing Buddhism for decades to the extent that it currently defines the Tibetan’s way of life (Sperling, 2004). It was because of these cultures that the Tibetans declined to submit themselves to the Chinese rule. China has always strived to control Tibet but the Tibetans have always opposed this attempt. Since 1951, the republic of China through the People’s Liberation Army (PLA) has tried to acquire Tibet by attempting to destroy their national as well as cultural identities (Macalester College, 2007). For instance, the nation tried to acquire Tibet by attempting to lure Tibet’s religious elite into voluntarily agreeing to embrace socialism. According to the Tibetans, this has always been referred to as cultural genocide (Stokes, 2010). Although China had assured Tibet that their Buddhism religion and culture would not be affected by the inauguration, Tibet was not confortable fusing with the Chinese Buddhist Association (CBA). According to the Tibetans, fusing with the CBA posed a threat for the Tibetan’s religion as well as culture. According to Sperling (2004), China is ever attempting to forcefully acquire Tibet. The reason why China is ever wishing to acquire Tibet is that it believes Tibet is located within China’s territory. Since almost all Tibetans practice Buddhism while the Han Chinese does not, the republic of China is ever attempting to ruin this religious culture in a move to ease the acquisition process. However, Tibetans always fight back in order to prevent China from ruining their culture and religion. Through Dalai Lama, Tibet was stable to the extent that even after numerous conflicts, China has never succeeded in acquiring it. It was through Dalai Lama that Tibet was able to fuse religion with politics. By intertwining Politics and religion, Tibet was able to create a solid foundation that made it difficult for the republic of china to acquire (Sperling, 2004). This technique was quite beneficial to the Tibetans since it motivated them into pursuing independence and self-autonomy. To date, the conflict between Tibet and China still exists despite numerous diplomatic interventions. Although Dalai Lama was quite influential in Tibet, he fled to India when he currently resides. Analysis In order to form the foundation of their adherent’s lives, both the Hindu and Buddhist religions ensured that they encouraged one another to fully embrace their religion. For instance, through this motivation, all Tibetans embraced Buddhism. Whereas the conflict between India and Pakistan resulted from the inability of the two nations to align Hindus with India and Muslims with Pakistan, the case was almost similar to that of China and Tibet. The conflict between china and Tibet began because China did not want Tibetans to practice their cultures and religions in a territory they claim was theirs. Additionally, the conflict was also triggered by the fact that Dalai Lama had planned to make Tibet an independent nation (Macalester College, 2007). Conclusion For a long time, India and Pakistan have been engrossed in conflicts. Although these conflicts started on grounds of religion differences, they rapidly escalated to territorial conflicts whereby both nations began fighting over Kashmir, a region located between India and Pakistan. Apart from India and Pakistan, China and Tibet have also been engrossed in conflicts, which have lasted for decades. Just like that of India and Pakistan, this conflict also revolved around religion but gradually grew into territorial conflict. China was not comfortable with Tibet’s Buddhism religion, hence, attempted all measures to disrupt it but Tibet was not ready to allow this to happen. Dalai Lama, a prominent leader in Tibet, was planning to declare Tibet an Independent nation. This idea was never taken lightly by China and it is because of this that the conflict intensified, thus, Dalai Lama was forced to run to seek refuge in India where he resides to date.

Direct iron ore smelting process development

IntroductionThe smelting decrease ( SR ) of Fe ore is an alternate natural stuffs treating method similar to the blast furnace. It begins with solid natural stuffs such as coal and Fe ore. The concluding merchandise of this procedure is a liquid Fe based stuff known as hot metal, or hog Fe when it is solidified. This terminal merchandise is the same as that generated by blast furnaces. Typical hot metal composings are about 4-4.5 % C, .3-1.5 % Si, .25-2.2 % manganese, .03-.08 % S, and.04-.2 % phosphoric. SR is the new age alternate to pig Fe production with the capableness of uninterrupted operation. The engineerings used in this procedure are similar to those used in both modern blast furnaces and conventional non-ferrous smelting operations. As developments in blast furnaces and non-ferrous smelters were made, such as the innovation of the Cu flash smelting engineering, developments were made in SR of Fe.Smelting Reduction Chemical reactionsThe natural stuffs used in SR are: pulver ized Fe ore which consist of Fe2O3 and Fe3O4 with remainders, powdered coal, limestone ( CaCO3 ) , and dolomitic limestone ( CaMg ( CO3 ) 2 ) . The transition of Fe ore into a liquid hot metal begins with the combustion of coal into C monoxide ( CO ) and H gas ( H2 ) which are the cardinal compounds for Fe decrease, equation 1. The C monoxide and H gas produced from the burning is used to get down the decrease of Fe ore by equation 2. The chemical reaction for regenerating the CO and H2 with coal from equation 2 merchandises is given by equation 3. Full decrease of the Fe ore is so shown by equations 4 and 5. Coal + ?O2 > CO + H2 ( 1 ) 6Fe2O3 + CO +H2 > 4Fe3O4 + H2O + CO2 ( 2 ) 2C + CO2 + H2O > 3CO +H2 ( 3 ) 2 Fe3O4 + CO + H2 > 6FeO + H2O + CO2 ( 4 ) 2FeO + CO + H2 > Fe + H2O + CO2 ( 5 ) These reactions begin in the solid province ; nevertheless, as decrease series begins the reactions become liquid province. The limestone and dolomitic limestone are added as fluxes/slag agents. The adaptability of many of these procedures to utilize a assortment of coal chemical sciences without the coking measure is the most alone belongings of SR fuel over blast furnace fuel. This usage of coal alternatively of coke eliminates the demand for a coking furnace every bit good as the usage of lower class coal.Smelting Decrease FirstsArchaeological finds in Africa show a crude smelting decrease signifier dating back every bit early as 2500BC. These ancient craftsmen would cut down Fe ore utilizing coke by blowing air into a shaft furnace. Martin Wiberg of Sweden every bit good as W. and E. Engell of Denmark began look intoing the smelting decrease procedure in 1938. However, much of the impulse in smelting decrease was lost between the 1950 ‘s and 70 ‘s due to progresss in the solid province decrease procedure known as DRI ( direct reduced Fe ) and in blast furnace engineering. It is of import to observe that without the air separation engineering conceived during the Second World War SR would non be executable. By 1981 the first SR pilot works was constructed in Germany based off the COREX design construct. In 1988 the first all-out SR installation was constructed based off the same pilot works at the site of a old blast furnace.Smelting Reduction Reactor TypesThree chief SR convertor types exist: the shaft convertor procedure, a two phase chemical procedure, and the intercrossed procedure. Both the shaft convertor procedure and the two phase procedure usage chemical energy for the decrease. However, the two phase procedure differs from the shaft procedure by implementing two transition Chamberss, a solid province chamber followed by a liquid province chamber. The intercrossed procedure is the most alone because it gets energy parts from chemical rea ctions and electrical current. Of these three types merely two procedures have been put into operation in all-out installations, the COREX procedure and the HIsmelt procedure. The COREX procedure was the first all-out SR installation as antecedently mentioned. This procedure is a two phase procedure. The first phase in decrease is the solid province reaction and natural stuffs preheating subdivision. Off gas from the 2nd phase is used to cut down and preheat in the first phase. As the ore transforms into a liquid it moves to the 2nd convertor phase where the liquid province decrease is completed. The COREX procedure has three theoretical accounts, the C-1000, 2000, and 3000. Primary differences between the theoretical accounts are the production capablenesss. The C-1000 installed in 1988 has a day-to-day production capableness of 1000 dozenss of hot metal. The C-2000 will bring forth 2000 tons/day ; it presently has 4 operating workss with the first installed in S. Korea, 1995. [ 2 ] The C-3000 is the newest installation with one works located in China. The SR furnace was installed in 2007 and has a day-to-day production capableness of 4000 dozenss of hot metal [ 7 ] . Figure 2 is an image of the C-3000 works. The HIsmelt was the 2nd SR procedure to go full production. Pilot proving of this procedure began in 1982. The procedure is a uninterrupted shaft transition furnace. [ 2 ] HIsmelt implements many engineerings presently used in non-ferrous smelting like uninterrupted stuffs feed by spears into the liquefied bath and H2O cooled furnace panels. [ 5 ] The full graduated table works which was built in 2003 was a 400 million dollar undertaking between RioTinto, Nucor, Mitsubishi, and Shougang coprorations. The works is located in Western Australia. [ 9 ] This procedure can utilize the off gas for multiple applications such as fuel for electrical power coevals or preheating the provender stuff. A elaborate position of the reactor vas. Additional SR procedure which are non presently commercialized include: direct Fe ore smelting ( DIOS, two phase reactor ) , AISI ( two phase reactor ) , and IDI ( intercrossed SR ) . Although SR procedures do non implement coke furnaces the coal demands remain similar holding small consequence on environmental emanations.DecisionSR is an progressing engineering capable of continuously bring forthing hot metal similar to a blast furnace with a wider scope of coal type. This natural stuffs flexibleness is a great advantage to SR. The riddance of the coking furnace lessenings project capital ; although, it has small impact on environmental emanations. SR has many great properties which makes it a competitory option to blare furnaces.Mentions[ 1 ] LIFE. ( n.d. ) . Chinese Premier Wen Jiabao Visits Australia.

Ethnic or Communal Politics in Malaysia Essay

The results for the ethics awareness inventory that I took last week for class revealed that my ethical profile is most related to obligation and least related to equity. Being related mostly to obligation means that my ethical profile is based on a sense of duty to do what is correct or right. Being least related to equity means that my ethical profile is based on absolute standards of right and wrong rather than practical analysis. How this Applies to my Personal and Professional Life In my professional and personal life I personally feel that obligation and a sense of duty to do what is correct or right fits me well. Since I work for a company that deals with national security and background investigations obligation is something that is required. In order to complete a background investigation there are many steps that need to be completed. My job personally is to obtain records on the subject that are required to complete the investigation such as resident, education, employment records and law checks with police departments. In order to complete these records there are certain guidelines that must be met and followed. Therefore, the duty to do what is right and correct is expected. How my Education has Affected my Ethical Thinking. In m y opinion my education has affected my ethical thinking in many different ways some of which I did not even realize. Some of the most important ethics that I have are honesty, time management and respect. Throughout my education at the University of Phoenix there have been many times that these ethics have come up in conversation and I have had the chance to see my classmates points of view on each one. One way that I have used honesty, time management, and respect in my thinking, decision making and potential for conflict is while working in teams throughout my educational experience. It can be very challenging at times depending on others to complete assignments and there is always a potential for conflict when working with other personalities. Therefore honesty with team members about things that are going on to prevent work from being done, time management when completing assignments and respect of others opinions are all ethics I use when working in teams.

Religious Clothing Restrictions Essay Example | Topics and Well Written Essays - 1500 words

Religious Clothing Restrictions - Essay Example In most cases, the wearers of religious symbols such as crosses, crucifixes and prayer beads, hijabs, burqas and niqabs are genuine religious people with a strong and real personal connection with religion. In other minority cases, people do wear religious symbols especially crosses and crucifixes as fashion accessories while some Muslims, Christians, Buddhists, Hindus and Jews wear these attire and symbols due to the politics of identity. However, this discussion proves that, a majority of these people who put on these religious clothing are honest followers of their respective religion. It is important for people to respect other people’s religious beliefs, and consequently abolish the restrictions imposed on the wearing of religious clothing; this is because most people wear religious attire as an expression of their respect for their traditions and religion. Wearing these clothes gives people a religious identity, and gives them a sense of self awareness and awareness of the requirements of their beliefs and traditions. Most of these people believe that wearing this clothes enhances their commitment to spiritual life and that affirming this to the public only strengthens their belief (Grimm). It is the work of the followers of a particular religious belief to decide among themselves what religious dress and symbols are appropriate in light of the teachings of their religion. Criticizing people’s policies and religious belief on clothing and religious symbol is usually received as criticism. of not only the individual, but the religion as well. Making observations in a prejudiced and uncourteous manner about the religious and traditional clothes and symbols of certain members of society would appear to be racial or religious discrimination which is against civil and human rights. In a democratic society, people should be accorded many rights, religion included. The right to religion translates to the right to express ones faith through actions, belief and even dress code. In Britain for example, the Government has expressed its social commitment to religious by promoting a diverse society with different faiths whose followers are universally treated as citizens of t he United Kingdom. In France on the other hand, the government officially banned the wearing of facial veils; this comes at an age where most Muslim women are married to domineering men who force them to wear veils. Some of the

Analyzing ad Essay Example | Topics and Well Written Essays - 750 words

Analyzing ad - Essay Example An advertisement is effective if it has passed on the linguistic message, denoted image and connotation image to the viewer. (Thesis) Here an advertisement printed in 2010 by Monsanto is analyzed for its linguistic message, denoted image and connoted image. The advertisement is of a middle aged African American who is standing with a field and harvester in his background. The advertisement has some texts too. The linguistic message , connoted image and denoted image can be thus further analyzed as follows; The text on the advertisement has some deep messages. The text projected on image directly gives a connotation to the image. There are two texts written on the image. One placed on the farmer’s shoulder and says, â€Å"America’s farmers grow America.† This gives out a connoted message that has been developed non-verbally. The phrase accentuates the farmer for his work and uses agricultural terms. The placement of the text also depicts conciseness. This connotation signifies the consciousness of the farmer. The other â€Å"Thanks a Million. Make that 11 million. Thanks to advanced farming practices, America’s farmers reduced their CO2 emissions 11 million tons in one year. That’s the same amount produced by 1 million SUVs. Few industries have shown such respect for the environment.†Now a new connotation is implied where the farmer is symbol of environmentally sound practices. He is also a symbol of industry. However the ad also gives out a co nnoted image. The connoted message in the advertisement is explicit in nature. According to (Chan) â€Å"Conversely, the connoted message is the culturally-laden text with its appeal to the writing and rhetoric of the photograph†. This ad shows a middle aged African American man standing in forefront with a field as the background. The man is looking to the distance with his head up and has an expression of thoughtfulness on his face. Over his shoulder a piece of machinery which is a harvester is
