Without using electricity, there are many ways to illuminate a parking lot. First, I can decorate the ceilings and walls of the parking lot with glow sticks (light sticks). This method of producing light is called chemiluminescence. Chemiluminescence is the direct production of light as the result of a chemical reaction with little or no heat produced. The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices are hydrogen peroxide and phenol oxalate ester. The hydrogen peroxide is kept in a thin small glass vial in the middle of the stick, and the second chemical phenol oxalate ester is in the main body of the light stick. Bending the light stick in the middle causes the small glass vial of hydrogen …show more content…
Bioluminescence is the production of light in living organisms as the result of a chemical reaction with little or no heat produced. By placing/releasing illuminative fungi, fish, and other organisms such as fireflies, glow-worms, and anglerfish in the parking lot, I can illuminate the space. Organisms can produce light by chemical reactions involving luciferin, and luciferase or photo-protein. Organisms absorb these chemicals from food or in a symbiotic relationship (bacteria with luciferin that lives in an organism). As a result of the chemical reaction of theses chemicals, a bioluminescent colour (green, blue, or yellow) is produced as a result of the change in arrangement of luciferin …show more content…
This problem occurs because the eye cannot refract well enough to form an image on the retina. It usually occurs because the distance between the lens and the retina is too small or because the cornea-lens combination of the eye is too weak, resulting light from nearby objects to be focused behind the retina. Thus, a converging (concave) lens/contact lens/positive meniscus with the middle part of the lens thicker than the edges help refract light rays to converge and converge again at the cornea-lens combination to help focus light on the retina to see a focused, sharp

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...

Unit 1 Pt1420

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...

The Birth and Evolution of Transistors and Impact on the Transport Industry

...Electronics rely heavily on electronic switching and amplification to generate and capture the various signals which allow them to operate. A controllable valve that allows a small signal to control a much larger signal does this, and could be related to a controllable valve used in the control of water flow. This was once done by a device known as vacuum tube but was later brought down to a much lower production scale for a variety of industrial, economical and business related reasons. Bell Laboratories, the research arm of telecommunications company American Telephone and Telegraph’s (AT&T) director Mervin Kelly put together the first team of researchers and scientists placed on the task of research and development of a solid state-semiconductor later called a transistor that would supersede vacuum tubes and provide numerous advantages. The success of this development would prove to change the computing, electronics and telecommunications systems altogether. Up until the invention of the transistor a vacuum tube was used in the control, amplification and generation of electrical signals. Vacuum tubes are tubes usually made from glass and designed in an airtight manner as to keep the flow of “cathode rays” from external disturbance as they pass from each terminal and laid the foundation for numerous technical innovations, such as the light bulb discovered by Thomas Edison (fig. 1). Joseph John Thomson further made a vacuum tube and placed a third terminal to attain a grasp...

...Blogging is popular among the people in today’s society, especially amongst teenagers. In fact, the number of blogs is exploding, with about 14 million existing blogs. On average, the number of blogs is doubling every five months. There are many advantages of blogging. Firstly, people can use as an online dairy, using it to share the day’s happening in her life with other visitors on the net. Furthermore, if the blogger (author of the blog) has met up with certain incidents in her life, he can share it on the blog and others can console or praise him, by giving comments or leaving a message in the blog’s tag board, depending on the incident. Blogging can also be a good way to relieve stress as some way wants to use their blog to vent out their frustration or pour out their woes when stress becomes too much for them. Some bloggers even use their blogs to flaunt their literati skills by posting poems about themselves or things around them. Secondly, bloggers can also use their blogs to inform others on a certain topic which happens to be his niche, thus allowing others who are interested in the topic to learn some tricks from the blog, they are also post questions to the blogger if they meet up with problems.

Fortune 500

...As the old saying goes “Only the strong survives,” seems to be true in this struggling economy, and this statement is true when referring to AT&T which is among the strongest company’s listed in the Fortune 500. AT&T’s success is garnered by a willingness to function well as an organization, and also by being leaders in innovation. For a company to be successful there has to be proper planning, organizing, leading, and controlling on their part,  coupled by the awareness of internal, and external factors, and how they affect the company.       According to "AT&T" (2012), "We're recognized as one of the leading worldwide providers of IP-based communications services to businesses. We also have the nation's largest 4G network – covering 275 million people, and 2,000 more 4G cities and towns than Verizon, and the largest international coverage of any U.S.” That statement alone says that AT&T has a well defined business plan, and economical external factors, such as their competition will not stand in their way. AT&T has not allowed internal factors like having to find qualified people for the jobs, and then training them affect their “bottom line,” and they understand that the quality of their employees affect their customer satisfaction, and customer satisfaction is key when dealing with a competitive market. One of the main components of the four function of management is leading. Leading in this sense is, stimulating the employees to achieve their goals and perform...

...college of business were our focal point. Surveys were given to students with questions regarding financial hardships caused by laptop requirement and their opinions of the policy among others. Faculty was interviewed on their thoughts and how the policy helped with the classroom. Administration helped with the reasoning behind implementing the policy and some hints to phase outs of the computer labs located in the college of business. We found that students believed that the policy is not effective, but should be enforced. For faculty, some believe that the policy is helpful for learning and welcome laptops in the classroom while others feel that laptops can be a distraction to everyone. The administration implemented the policy because they want students to have the ability to work anywhere at any time with the specialized tools/software needed for courses taken. They also feel laptops are necessary for non-traditional students who may be full time professionals and have the option to complete courses online. Rumors that the laptop requirement was put into place because of possible computer lab phase outs are false, null, and void. To improve the effectiveness of the laptop requirement in the college of business, we recommend the following: * Making sure students/faculty are aware of the laptop requirement * Enforcing consequences for those who don’t have a laptop Thank you for welcoming our concerns and suggestions through this project.

...Alcatel-Lucent is a global telecommunications corporation located in Paris, France. It has, under its wing, Bell Laboratories aka Bell Labs. They were previously known as AT&T Bell Laboratories and Bell Telephone Laboratories is now the research and development subsidiary of the French-owned Alcatel-Lucent. Over the past eight decades, Bell Labs R&D gave birth to new technologies and seminal scientific discoveries. (Alcatel Lucent, para 1) Elisha Grey and Enos N. Barton formed Western Electric Company in 1869. Both of them started a small manufacturing firm based in Cleveland, Ohio which was to become the largest electrical manufacturing company in America. In 1881, Alexander Graham Bell, an extraordinary leader of American Telephone & Telegraph (AT&T), purchased a controlling interest in Western Electric and made it the exclusive developer and manufacturer of all equipments for the Bell telephone companies. Now, the Bell system has provided much telephone services and support to America and Canada in the 1877 to 1984. It was then led by AT&T. In 1898, Compagnie Générale d'Electricité (CGE) was born, founded by a French engineer named Pierre Azaria. It was involved in business with several industries in Germany. Mainly it dabbled in electricity, transportation, electronics and telecommunications. CGE then rose up the ranks and became a leader in digital communications and would be known as well to produce train à grande vitesse – high speed trains in France. In...
