The Serial Peripheral Interphase - 533 Words

The Serial Peripheral Interface (SPI) is a synchronous bi-directional (full duplex) serial data protocol used by microcontrollers to enable communication between one or more peripheral devices that are all of short distances to one another. Furthermore, it can also be used for communication between two microcontrollers; with particular interest between Arduino boards and Multiwii flight controllers. In general, an SPI data link consists of one master; typically a microcontroller which controls one or more peripheral devices known as slaves. Both the master and the slaves share three common lines which include; MISO (Master In Slave Out) which is responsible for transferring data from the slave to the master; MOSI (Master Out Slave In) which is responsible for transferring data from the master to the slaves; and SCK (Serial Clock) which is created by the master and is responsible for synchronising the transmission of data between master and slave in respect clock pulses. There is also SS (Slave Select) line that is specific to a pin on each slave device and in which the master can use to enable and disable specific slave devices. In the case a slave devices SS pin is low, communication is enabled with the master. However in the case it is high, communication is disabled with the master. This allows multiple devices using SPI to share common MISO, MOSI, and CLK lines. Full duplex data transmission occurs during each clock cycle generated by the master in which the masterShow MoreRelatedProject Managment Case Studies214937 Words   |  860 PagesDivision, which manufactures disk drives, the Lampco Division, which is responsible for Department of Defense (DoD) contracts such as for military application, satellites, and so on, and the Ridge Division, which is the primary research center for peripherals and terminals. CONTINENTAL COMPUTER CORPORATION According to Ed White: Our major problems first began to surface during the early nineties.

Little Tsukiji The Market Industry Profile Essay

The Market Industry Profile Little Tsukiji is a Japanese restaurant serving sushi, sashimi and teppanyaki. Japanese food is very much popular in Singapore. In Singapore, it is very common for office workers to eat out for lunch. â€Å"As of 2001, there are more than a hundred Japanese restaurants in Singapore, of which about one-third are sushi restaurants. The rest include family restaurants, izakaya, teppanyaki, ramen and fast food restaurants. And in many Japanese restaurants, sushi and/or sashimi is a must on the menu.† (Ng, 2001, Pages 8 – 9) Therefore, the choice of a restaurant specialising in teppanyaki, as it is not as common in Singapore and there is a lot of opportunity to make a mark with differentiation in products. Competition for teppanyaki is not as strong as it is with sushi restaurants as there are not as many teppanyaki restaurants around Singapore. Additionally, where there are a group of restaurants, a few are bound to be Japenese restaurants serving different types of Japanese food. Within the neighbourhood of Tanjong Pagar (targeted location for setting up the restaurant), the Japanese restaurants in the area are that of sushi, sashimi, ramen, gyoza restaurants. There are other Asian cuisine restaurants around the area such as Korean BBQ and Vietnamese food. More details about the competition will be discussed in the next section, â€Å"Competition†. Japanese food is a huge trend in Singapore that is still growing. In Singapore, there are Japanese

Journalism Developments and Debates

Question: Discuss about theJournalismfor Developments and Debates. Answer: Reason for Wanting to Study Journalism Since a long time, I have been cherishing the dream of studying journalism. In todays world, journalism is a dynamic profession. It is not because I will be able to travel various places while collecting news, but because it will allow me to understand the world and the humans. I always had a knack for collecting news and writing it down. However, I want to study the subject to learn professional skills, and theories and practices of journalism from past to the present. As a subject journalism covers a lot of areas. Starting from politics, art and literature, cinema, television, to international relationship, business, science, economics; journalistic writing is applied in all these sectors. After completion of my course, I will be able to choose the area I wish to write about and then explore it with my own capability. Journalism, as a profession, is gaining not only popularity but validity with time. People are hungry for news. They want to know in detail what is happening around the world. They want to know all interesting news. It is the responsibility of the journalists to aware them about every situation. Journalists are bound to find all interesting news and cater them to the public. Even in some cases, their presentation makes the story interesting. I am willing to know how they work and what they focus on. It s also seen how journalism as a profession have undergone changes with the advent of digitization. Now we avail news from internet. Various social media websites are working as a communication platform for the journalists. After doing my course, I will be able to explore my profession with the help of technology. Understanding of Changes in Contemporary Media and the Impact on Journalism In an age of globalization, media has undergone a complete change. Starting from the communication platform to the type of news catered to the public, journalism as profession has become a more dynamic one. Newspaper, radio and television were the main communication media. However, with the technological explosion and development of internet, media has started using these platforms as well. Nielsen et al (2013) opined, Digitization has made the communication easy. It is a fact that we want to get the news as fast as possible. According to Neumayer (2013), in earlier days, newspaper was the only medium. One had to wait for the next day to get the news of the previous day. Then television and radio came. It made the availability of news faster than newspaper. However, these media platforms started become old when internet established itself as the fastest of all. As discussed by Franklin (2012), now, people dont have to wait at all. Every incident of every single moment is catered to people through internet. Such changes have made journalism more challenging than before. With the explosion of news, now we dont want to wait. Even, people do not waste their energy much on same news story because of the availability of bunch of news stories within a short period. Therefore, news stories are having less longevity. Neveu (2016) discussed, it is estimated that between 2007 and 2015, CNN has edited their news packages into half of their original length . It is the challenge of the journalists to make every news story interesting. Otherwise, it will not sustain. Sometimes, it has resulting into yellow journalism which is not acceptable. Kammer (2013) explained that as a negative impact, the journalists serve invalid and not so valuable news stories in some cases to retain public interest. Sometimes, it crosses the limits of libel. However, journalism is not a profession where the journalists can write anything that happens. It is about making the authentic and accurate story and serving it to those who need them. To talk about positive impact of journalism, it is needless to say that it has given birth to personal blogs and websites in large numbers. The aspiring writers are enjoying the freedom of speech. According to Picard (2014), the bloggers do not belong to any specific media banner. Therefore, they are able to exercise their own point of view through blog writing. They are true to their own emotional outcomes and do not depend on any media house. Surely, the profession is earning them both money and job satisfaction. The readers are also exercising their choices. They are given thousands of stories from which they select the ones they prefer to read. Surely the change has made journalism a challenging profession.

Domestic Violence Essays (1704 words) - Domestic Violence, Abuse

Domestic Violence Domestic Violence in America Introduction: Today in American society we have many social ills. Perhaps one of the most upsetting, at least to me personally, is domestic violence. Domestic violence can come in many shapes and forms and affects many different people. Reasons vary for spousal/child abuse, but none are justified. Police/community programs have recently had a more pro-active role in domestic violence, but that is not a solution to our problem at large. On the micro level, the ultimate responsibility of elimination of violence rests on the victim. On the macro level, we must look at our society critically and analyze why we have such an immense problem and how we can help correct it. In the following sections I will discuss domestic violence issues and attempt to offer some solutions. I will frequently use anecdotal evidence, as well as statistical figures. I assign genders to the abuser and victim using he and she or husband and wife frequently?this is for simplification. Although most victimization is male agains t female, I am generalizing for simplicity. Discussion: Domestic violence is a prevalent issue in the United States. There is much controversy as too how much violence actually exists in America (much of it takes place behind closed doors and is difficult to identify), but assuredly we have a problem with the issue as it is reported that almost 4% of American families experienced severe physical violence of a degree that had the probability of inflicting injury or death upon the victim (stabbed, gun used, beat up, punched) (www.silcom.com/paladin/madv/faq-dv.html). This 4% may seem like a small figure, but it equates to four million victims (and that only includes the major injury-inflicting violence). Another source states that 1 in 3 women will be assaulted by a domestic partner in her lifetime (www.npcts.edu/uo/handson/domviol/statfact.html). Another source indicates that 63% of parents have engaged in violent acts towards their children (Assaults Against Women and Children, p. 219). Truly this issue is unacceptable in a civil society such as ours. Domestic violence, when most people hear that term, think of husbands assaulting wives. This is an unfair generalization. Violence is more likely against women than men but nevertheless women are sometimes the perpetrators. Another fact left in the corner when discussing domestic violence is how much occurs between high school boyfriends/girlfriends. Figures indicate that 1 in 10 high school students has experienced physical violence in dating. The figure rises to 22% for college students (www.npcts.edu/uo/handson/domviol/statfact.html). Perhaps most importantly and tragically, children can be affected by domestic violence in both direct and indirect ways. A clear estimate of abuse is difficult to determine due to data collection methods and a precise definition of violence against children, but statistics indicate that up to 3 million children are abused/neglected each year Of this number, a mere 150,000 cases are reported. (Don't Call it Child Abuse, It's Really Poverty, p. 260). This number is astronomical and totally unacceptable. Even if children are not directly abused, many witness their parents abuse each other. As a child I witnessed domestic violence (fortunately mostly verbal) nightly when I was young. I didn't understand why they fought so much and so often. I couldn't imagine the way I would have felt had my parents truly injured each other. Most of the time they broke stuff and yelled and screamed. I remember the only way I could interpret the situation (like many other kids) was to blame myself. The emotional stress violence places on kids (even if not directed at them) is a very serious issue. There are many reasons that spouses choose to beat their wives/children. One explanation that is popular is that of frustration. The (often) male authoritarian figure in the household in today's society is often threatened by a burden of responsibilities. Even if the wife does work, often the male feels responsible to be the ?breadwinner.? If he is unable to fulfill his role, or if he feels that the role is threatened, (job problems or wife earning more), he is likely to become disgruntled. This stressful situation leaves the person feeling powerless and without control. The one place where he (again, most of the time it is a male) can have total power and control is

HCA Healthcare Corp Essays - General Electric, Free Essays

Columbia/HCA Healthcare Corp Essays - General Electric, Free Essays Columbia/HCA Healthcare Corp Business Level Strategy The business level strategy of GE in times past has been concentrated on providing heath care equipment to approximately 300 hospitals that were run by Columbia/HCA Healthcare Corp. But GE, run by Welch, has diversified greatly. Moving from a primarily manufacturing firm to becoming a more service oriented firm. One of the first big steps for GE to move into the services market was when Columbia allowed them to service all of their imaging equipment, including those made by GE's rivals. Differentiation The strategy of differentiation for GE is in their vision of improving the quality of their products and services. Welch decided earlier this year to improve GE quality with the expectation of boosting their revenues. Overall Cost Leader GE is already seeing a competitive advantage in streamlining their organizations that reduce operating costs and increasing revenues. In fact, they have done this so well that other organizations have been willing to hire GE as a consultant to show them the tricks of the trade that will increase their bottom lines. GE has been offering flat rate full service contracts for many of its customers that are raising the eye brows of competitors. Focus The focus for Welch has been directed on GE and GE alone. It was stated that he doesn't sit on any outside corporate boards and is devoted to the success of GE. Prospector GE is definitely categorized as a prospecting type of company. As the article outlines, GE is a company that looks for new markets and new growth opportunities and is willing to accept some level of risk. Along with successfully being involved in Medical Systems, Aircraft Engines, Power Generation, and Transportation, GE has been busy working on global computer services that appears to have phenomenal potential for them. Corporate Level Strategy As all of GE's business entities get direction from Welch on a business level strategy, he has come up with a corporate level strategy that has his competitors guessing what next? Welch appears to have enough vision to see what industry is doing as a whole and not just what the manufacturing industry is doing. This vision has driven his company to seek out opportunities that are more service orientated. Concentration The diversification of GE in recent years tends to make one believe that GE does not concentrate on just one thing. But GE has concentrated on manufacturing as its primary task in the business world. But Welch has changed that task to providing services. A company that can effectively provide a product and then turn around and be the sole service provider for that product will seemingly be in a position to where its competitor cannot touch them. Growth Penetration - GE has been able to increase its customer base by providing a complete package that includes products and services at flat or lower cost. Expansion - GE is also expanding into new areas, such as providing services for its existing product line along with the product line of its competitors. GE is also working on becoming a service provider for corporate computer networks around the world. This would put them in direct competition with IBM and EDS, companies that were not seen as competitors in the past. Globalization GE has been very strong in the international market in the past but is positioning itself with a much broader dominance by implementing a variety of services for companies abroad. Horizontal & Vertical Integration Horizontally, GE is not carving away at its competition all that much, but it wants to become much more vertical in different areas of the international business world. For whatever business GE is in, it wants to be able to dominate it from the top down. This vertical expansion goes forward as well as backward. If GE is unable to buy a given reseller or supplier it makes sure that the contract states that its customer must go through them for all aspects of the business. (i.e. products and services)

Waste Water Management Coursework Example | Topics and Well Written Essays - 10000 words

Waste Water Management - Coursework Example It seems impossible that one universal method will be able to satisfy the situation, thus there are several methods and techniques that have been devised to detect and dispose off the organic pollutants. It is important to distinguish the effectiveness and robustness of a technology, while searching for the most efficient one amongst the various water treatment methods available in the market. The need is to overcome the environmental vulnerability, without sacrificing the performance levels of the water treatment techniques. There are several technologies that present effectual solutions for the versatile water treatment issues but at the same time possess considerable flaws. For example, one of the most popularly used water treatment methods is with the help of activated carbon or zeolite surfaces. In this method, the contaminants are separated from the water by transferring them to relatively highly charged surface area of the water sample. The drawback of this method is that the pollutant needs to be disposed after the adsorbent is exhausted and often mixes in the water again. Similarly other methods like, thermal oxidation treatment (extremely energy intensive), biological treatment (which has failed to provide results with high variation of pollutants), have not provided the research community with the desired results. This paper presents a review on the work done on photo catalytic oxidation reactions---a type of Advanced Oxidation Process (AOP's). It presents the option of water treatment by the photo catalytic oxidation process in a UV reactor system to mineralize organic contaminants in water with the help of a semiconductor catalyst TiO2. Thus the paper explores the recovery of water from waste water as an alternative water resource. It also throws light on the different water treatment technologies prevalent today and their comparison with the photo catalytic reactions. Using UV water treatment method for disinfection of waste water dates back to 1915 in the U.S. and since then the costs of the method have depreciated largely, thereby opening news roads and allowing the researchers to develop effective UV methods to disinfect water and wastewater. In these oxidation methods, water is treated with the help of
