How an iPod works Essay Example | Topics and Well Written Essays - 500 words

How an iPod works - Essay Example You want to know more about this Ipod, but are overwhelmed by the technical jargon of MP3 and DMZ protocol. Yet, under that veil of secrecy lies a simple device that requires only a simple understanding. The Ipod is a three-step process of getting an input, looking for some human interface, and giving an output. Long before you listen to a song on your Ipod, a studio somewhere on the West Coast had disassembled the song and broken into small pieces waiting to be purchased. They take these pieces and squeeze them down and compress them into small packets called the MP3 format. When you order this song it is quickly thrown into a delivery system called a download. The packets come through the Internet, into your computer, out to your Ipod, and are stored in a box called memory. The squeezed packets, under great pressure, will sit and wait until their next calling. The song that was broken up only moments ago has buried itself deep within your machine through a step called input. The input sits in the box and waits for the human interface. In the world of Ipod, the output is the small brain, the human is the big brain, and the input is no brain at all. Here in the 2nd step the Ipod waits for human control. The big brain kicks in and presses the right buttons, it locates the mood, and navigates to the proper memory box. The big brain sets the tone, volume, and play list.

Women and Film Essay Example | Topics and Well Written Essays - 1500 words

Women and Film - Essay Example In fact she is shooting at the strictures that life has posed for her and Thelma, and the rest of the film shows them breaking out of them. Thelma and Louise starts with two shots that portrays women in a very ordinary, subservient roles. Thus "LOUISE is a waitress in a coffee shop . . . she is in her early thirties, but too old to be doing this", while "THELMA is a housewife . . . slamming coffee cups from the breakfast table into the kitchen sink, which is full of dirty breakfast dishes and some stuff left from last night's dinner. . . "1 They are both, at this stage at least, apparent caricatures of the controlled and limited lives that women are forced to lead. Most telling here is the fact that Thelma must ask her husband if she can go, rather than merely informing him that she is going on a trip with a friend. Louise's reaction is also very revealing as she, while the apparently more independent of the two, at least legitimizes the idea that her friend should have to gain permission from her husband. She immediately expands it to the "husband or father" comment, but her initial (and thus perhaps instinctive) reaction is to annoyed because they are just about to leave and Thelma hasn't gained permission. The first The first sign of rebellion in these early minutes of the film comes with the screeenwriter's note that Thelma "decides not to tell him" (her husband) that she is going on the trip. Her husband, along with nearly all the men portrayed in the film is vain and arrogant, without having the goods to back up either tendency. Men are shown in the same two-dimensional light that women are normally portrayed as in films. Thus all the men are vain, violent and/or stupid in the same way that women are often seen as money-grabbing, mothers or whores in most films. Thelma and Louise must break away from these two-dimensional caricatures in order to find themselves. The hint that violence may be at least a possibility occurs when Thelma surprisingly puts a gun into her bag along with a box of ammunition, with the rather cryptic comment "psycho killers". Whether she is referring to potentially violent men or whether this is perhaps a foreshadowing of the crime spree that she and her friend are just about to stumble into is unclear. The lack of clarity as to why what is about to occur does actually happen has perhaps contributed to the varied critical opinion of this movie. Thus while Nick Schager, in Slant, argues that the film's "feminist call to arms winds up sounding woefully simple-minded"3, Matt Brunson disagrees, saying "this beautifully realized picture remains a trenchant, almost mystical slice of Americana"4 Most critics seem to have fallen somewhere between the two, suggesting that the apparent glorification of casual violence that the film portrays is in fact a reflection of a certain segment of American society. As Wesley Lovell writes, Thelma and Louise is "a

Cosco Case Study Example | Topics and Well Written Essays - 750 words

Cosco - Case Study Example al., 2008, p. C-3). While this business model has been entirely successful thus far, the provision of limited choices can be problematic in the long-term. With globalization consumers are increasingly confronted with a variety of choices. Therefore shopping in an environment with limited choices may go against what modern consumers have come to expect and prefer. Costco’s business model has nevertheless been successful so far. For example in 2006, total sales in Costco’s 496 stores worldwide amounted to US$ 59 billion. Membership included 26 million private members and 5.2 million business members which amounted to US$1.2 billion in fees for Costco membership. Each of Costco’s stores realize sales each year at an average of US$128 million while its closest competitor Sam’s Club realizes only US$67 million annually (Thompson, et. al., 2008). However, since Costco and Sam’s Club are based on the same business model, the disparity in sales might be a m atter of concern. Costco can expect that at some stage Sam’s Club will attempt to take some of Costco’s market shares and the sales’ positions can be reversed. ... For example, operating costs increased progressively from US$1,037 million in 2000 to US$1,626 in 2006. However, net sales and membership fees together increased from US$32,164 million in 2000 to US$60,151 million in 2006 showing progressive increases from year to year. At the end of 2000, Costco had 313 stores operating worldwide and by the end of 2006, Costco had 458 stores. Membership has also followed a similar pattern, increasing each year from 2000-2006 (Thompson, et. al., 2008). Although membership is a big part of the business model it is a more significant marketing strategy and will be critiqued in the next section. The successful business model of offering quality goods at low prices is enabled by the warehouse membership set-up. By taking this approach, Costco is able to save the cost involved in in-store decorum and in-store customer service. In fact, Costco’s various warehouses typically display bare cement floors and shopping is designed like a â€Å"treasure h unt† experience (Thompson, et. al., 2008, p. C-6). Moreover, Costco offers limited products in volumes to lower the cost of inventory and floor management. For example, a typical supermarket or supercenter such as Wal-Mart or SuperTarget will offer between 40, 000 and 150,000 items while Costco offers only 4,000 items (Thompson, et. al., 2008). Thus far, Costco’s business model has been successful, however increasing competition indicates that Costco might have to consider revamping its business model. For instance, Costco’s largest business rival, Sam’s Club and BJ’s both use a similar business model. Both Sam’s Club and BJ’s have similar in-store lay-outs, offer about 4,000 items and feature the treasure hunt experience in which luxury goods are available at lower

Marketing of the financial services has been one of the recent phenomena even in the developed nations of the world. The financial service sector has not been subjected to the market pressure in an attempt to survive and prosper. This sector has operated in the benign market environment in most of the countries and has been managed and controlled by the state itself. The government has helped in the development of the new products as well as in the promotional activities. The strategic marketing planning helps to set the direction for the medium to long-term. In order to complement the strategic marketing plan, it would be best for the companies to have an annual marketing plan in order to achieve the short term marketing objectives (Ennew & Waite, 2007).

Integrations and reflection Essay Example | Topics and Well Written Essays - 500 words - 1

Integrations and reflection - Essay Example My skills and abilities to deal with numbers have also increased and I am now able to interpret figures well. This course has made me more confident in terms of handling statistical tools. During this session I was asked by my teacher to create a project that would encompass all the statistical methods and this would be used to analyze the data of real life organization. I tried my best to fulfill the conditions of the project but somehow I feel that I could have done better by incorporating more of statistical methods and getting them approved by my teacher before applying them on any real time data. I did not understand three topics related to the course that is ANOVA and regression, statistics survey, and probability. These topics I feel were not well explained by my teacher. These topics need further improvement according to me and I feel that it would be more beneficial if more problems are given in the class to be solved (Johnson & Kuby, 2011). These problems should be diverse so that students are able to apply maximum methods to derive solutions and interpret the results. In any course it is very essential to build a strong knowledge base as on it lays the future progress and development. I feel the best way to measure to future progress is by evaluating the level of understanding. If I opt for a career related to statistics then my marks would be a measuring tool for the outcomes of this course. The other factor is that this course would enable me to think towards a direction and choose a career that would help me to explore the skills that I gained through this course. I was able to achieve the outcomes of the course however I feel that I could have been more proficient with the statistical tools and methods. I was able to understand the different approaches in statistics and would be able to deal with problems efficiently in the future. The other learning outcome that I achieved is that of

Why Americans should embrace Alternative fuel vehicles Term Paper

Why Americans should embrace Alternative fuel vehicles - Term Paper Example If this trend is to continue in the future, then very shortly the phenomenon of 'peak oil' would be triggered and global competition of remaining oil will escalate the prices beyond affordability. Moreover, there is the persuasive argument from environment preservation angle. If current energy usage patterns continue for a few more decades then the ecosystems and environments across the world would be damaged beyond repair, putting at risk the long-term survival of our species. (Borowitz, 1999, p.255) The rest of this essay will elaborate on these points and present the reasons why Americans should embrace alternative fuel vehicles. Beyond concerns about peak-oil and issues of sustaining conventional oil supplies, there is the danger posed by environmental pollution. While manufacturing industries play their part in polluting air, water and soil, the chief contributors are motor vehicles. For example, 90% of the carbon monoxide, 50% of the volatile organic compounds, and 40% of the o zone in metropolitan areas come from motor vehicles. (Meotti, 1995, p.27) With car ownership per-capita in America being one of the highest among advanced economies, there is a urgent need for alternative fuels. There is also the option of attempting to reduce car sales and car usage. But since this outcome is highly unlikely, finding substitute fuels for petroleum-based ones is the more plausible option going forward. Soybean oil is another alternative fuel that holds a lot of promise. When oil prices spiked during the first Gulf War in 1991, American farmers put to use the huge surplus of soybean oil stored in tanks across the country. They said that Soybean oil can be refined into bio-diesel, which can be used by vehicles. Already, by this time, bio-diesel was being manufactured in Europe using rapeseed oil. And by following the same procedure, Soybean oil could also be converted into bio-diesel, which would prove to be a cleaner and eco-friendly energy alternative. (Schmidt, 200 7, p.87) Experts and business people have now identified bio-diesel as a key player in the alternative fuels market. It also has the advantage of being produced by both small-scale manufacturers as well as large industries. While bio-diesel cannot completely substitute for petroleum products, it has the capacity to power a wide variety of vehicles. At present 95% of passenger vehicles in America run on gasoline. Bio-diesel can significantly help reduce this percentage. (Schmidt, 2007, p.87) Promoters of bio-diesel also feel that its advantages outweigh its disadvantages. It is not only a sustainable energy option, but also an eco-friendly one. For example, â€Å"Numerous studies show that compared to petrodiesel, B20 emits at least 10% less particulate matter, carbon monoxide, and total hydrocarbons. The relevant data are summarized in a 2006 NREL report titled Effects of Biodiesel Blends on Vehicle Emissions. Unlike fossil fuels--which contain carbon from underground sources--biod iesel contains carbon from plants that were recently alive and drawing carbon from the atmosphere. For that reason, burning it doesn't add more carbon dioxide to the atmosphere than what was already there. What's more, biodiesel contains 11% oxygen by weight, which enhances fuel combustion, and reduces the amount of carcinogenic soot that diesel engines spew into the air.† (Schmidt, 2007, p.87) Diesel-run vehicles, on the other hand, are decisively more polluting. They release a lot of sulphur into the atmosphere, which in turn creates sulfate-based particulates, which in turn
