...Unit 4 Research 1: Using Global Variables Advantages of using Global Variables * Global variable belongs to every function in the program. * Avoid passing frequently-used variables between several functions. * A global variable is accessible in every scope. * A global variable can potentially be modified from anywhere. * It can be accessed from any other files using extern. Disadvantages of using Global Variables * Non-locality -- Source code is easiest to understand when the scope of its individual elements is limited. Global variables can be read or modified by any part of the program, making it difficult to remember or reason about every possible use. * Implicit coupling -- A program with many global variables often has tight couplings between some of those variables, and couplings between variables and functions. Grouping coupled items into cohesive units usually leads to better programs. * Concurrency issues -- if globals can be accessed by multiple threads of execution, synchronization is necessary (and too-often neglected). When dynamically linking modules with globals, the composed system might not be thread-safe even if the two independent modules tested in dozens of different contexts were safe. * Namespace pollution -- Global names are available everywhere. You may unknowingly end up using a global when you think you are using a local (by misspelling or forgetting to declare the local) or vice versa. Also, if you ever have to link...

...Module 3 Position Paper Jerry Wilkins ITT Technical Institute There are many risks both health and environmental that take place when using hormones to genetically engineer food. According to the American Academy of Environmental Medicine (AAEM), several animal studies indicate serious health risks associated with genetically modified (GM) food. The AAEM has asked physicians to advise all patients to avoid GM foods. Numerous health problems increased after GMOs were introduced in 1996. The percentage of Americans with chronic illnesses and food allergies has gone up drastically. Reproductive disorders, autism, and digestive problems have steadily been on the rise as well. Although there is no sufficient research to confirm that genetically engineered foods are a contributing factor to these issues, there is still something about the process of genetically modifying the food that seems immoral and unhealthy. Between 1996 and 2008, US farmers sprayed an extra 383 million pounds of herbicide on GM food producing a "superweeds," which are resistant to the herbicide. This is causing farmers to use even more toxic herbicides every year. Not only does this create environmental harm, GM foods contain higher residues of toxic material. Roundup, for example, is linked with sterility, hormone disruption, birth defects, and cancer. GM crops and their associated herbicides can harm birds, insects, amphibians, marine ecosystems, and soil organisms. They reduce bio-diversity, pollute...

There are no chains or visible mechanical workings. Riders lean forward to move forward and back to move backward. Turning is done mechanically via hand controls. The device is driven by a quiet, nonpolluting electric motor and can travel up to 10 miles per hour. The name "Segway PT" stands for "Segway Personal Transporter. " The Segway was built in secrecy and was unveiled on December 3, 2001 , on the ABC program Good Morning America. [pic] [pic] The initial reaction to the Segway PT was enthusiastic. Venture capitalist John Doerr predicted that it would be as important as the Internet. Apple's Steve Jobs predicted that cities would be built around it. To cope with the expected demand for the product, Segway's factory in Bedford, New Hampshire, was designed to build up to 40,000 units per month.

...Kylie Lewis 4/9/14 Block 3 Segways: Terror Causing Torture Devices Treasured recollections with your best friend scrapbook themselves as terror-and-pain-free moments. Well, they should anyway, but with my best friend Alexis’s and my aptitude for disaster, my most memorable memories with her elicit injury-and-terror-filled life- flashing-before-my-eyes-moments. Thanks to our never-failing clumsiness, the four day trip I took with her and her eccentric family to St. Louis last fall break included slips down staircases, tumbles into rooftop ponds, and an accidental masterpiece resulting from a dropped pumpkin. Despite all of these unfortunate accidents, one escapade trumped all of them: The Great Segway Fiasco. Eerie, early morning fog shrouded our car on the morning it all began as we drove down the St. Louis streets toward the Segway rental place; Alexis’s mom had signed us up for a Segway tour. As we arrived at the Segway place, the tour leader presented us with a very clear set of rules. “Now, since your age of 12 doesn’t reach our city-street age requirement of 16, we’ll be taking you guys in the woods today. This means that the path will be considerably thinner, so you need to ride single file. If your tires bump against anyone else’s, you guys will crash. Remember, Segways are designed to continue moving along even after you get off of them, so make sure to lean your Segway against a tree or rock when you step off.” He barked loudly. After a century of learning how...

...The segway What has changed witht the invention of the segway? Steve Jobs said it would be bigger than the PC. Today, it used everyday with police departments, security companies, and golf courses. But the segway didnt revolutionize these departments. The Segway PT is a two-wheeled, self-balancing, battery-powered electric vehicle. It was marketed as a balance-sensitive machine that could transport a human at about 13 m.p.h. and last for a day on only 5 cents-worth of electricity. This brought the glamour of the segway, but it do anything new for these departments. People believed we needed it as a faster way to travel around in pedestrian areas, where vehicles were not allowed. This was the first of its kind, and did not replace a product, simply creating its own market. Invented by Dean Kamen, it is produced by Segway Inc. of New Hampshire, USA. This is a new technology, but merely an improvement in transportation. There were a couple problems with why the segway did not revolutionize transportation. Since Segways could go up to 13 m.p.h., they were not allowed on most sidewalks. However, they also went too slow for many roads, leaving customers unsure of where to ride them. Plus, the $4,950 debut price put the machines far out of budget for the average consumer. With such a high price, it could not become an item that everyone had, and why would you spend so much on an item you were unsure of where to ride it. There was also the problem of injury. In 2003, Segway...

...In December 2001, Dean Kamen of Segway LLC unveiled the Human Transporter HT. With lofty ideas of replacing the automobile and unrealized sales forecasts, Kamen's Segway HT has not moved mankind nearly as much as Kamen had expected. With an annual CEO change since start-up, it is apparent that Segway's lack of a stated vision and mission is haunting the organization. The lack of "a way ahead", coupled with a less than well-defined marketing strategy, has caused Segway to fall short of Kamen's expectations. Kamen, while a definite asset to Segway, could be a detour or even a dead end on the company's road to success. Historically, Kamen's successes have been based on his abilities to be innovative in research and design, while at the same time being able to pass the developed product off to a partnering company that is able to take the product to market. Kamen's emotional attachment to Segway is preventing its success. As if these problems were not enough, combined with the fact that there was no pent up demand for such a product, Segway's future success will be dependent on an organizational make-over. Segway Value Chain In order to highlight Segway's situation, I have broken down their value chain into two simple classes. Firstly I will focus on "what is working" and secondly on "what is not working" for Segway. What is working Technology: Segway uses their patented design to produce a socially responsible (green product), environmentally friendly mode of transportation...

...Paul Baptista Critique 2 New Product Planning SEGWAY In this critique I will be analyzing the product failure of the Segway PT a two wheeled (Personal Transportation) device that is battery powered that utilizes self-balancing technology. It is propelled by simply standing on the device and pitching your weight forward or backwards. The technology in the base of the Segway utilized motors and sensors to adapt to the angle or pitch the rider commanded and set forth the speed and direction, turning the Segway worked in the same manner by leaning with the handle bars to turn left or right which changed the speed of the wheels to turn in either direction. Segway was considered to be a game changing innovation in the way the regular person would get around, endorsed by big names like “Steve Jobs” from Apple and “Jeff Bezos” from Amazon, Segway seemed to be the new thing with a Blue Ocean approach in personal transportation market . In this critique I will be elaborating on the missteps taken by Segway’s entry to new transportation market facing regulatory transportation barriers, followed by the shortcomings with the quality of the product, and why the Segway failed to appeal to the market, lastly some suggested improvements. Barriers to Entry Segway had a plan to develop and change the way people moved around from point A to point B by creating a device that would be environmentally friendly and economically useful for everyday use. The problem the firm faced was once introduced...
