Skullcandy need to produce headphones of better quality, thus, the also create a housing for the speakers that will automatiically fit comfortably on the clients ear. Such headphones can…

“Who has read a Harry Potter book by J. K. Rowling?” My Seventh grade language arts teacher Ms. Edwards would ask the class. Most of the students would raise their hands. Some with glee as they read the whole series, others having only read one, maybe two books simply raised their hands. There I was, not raising my hand and feeling embarrassed, feeling like I didn 't belong like I was an outsider for not reading a book. Class would go on as usual but I was stuck on that one question, pondering…

PURPOSE/QUESTION The question that we will answer using this laboratory report is, “How is the rate of dissolving sugar affected by changing the temperature of the water, changing the rate of stirring, and changing the size of the crystal?” The independent variable of each laboratory experiment is different, however they are all being changed to get consistent and effective results for one dependent variable. The three independent variables are the temperature of water, rate of stirring and size…

The mathematical genius Alan Turing is famously known for proposing that if a machine behaves as intelligently as a human being, then it is as intelligent as a human being. This assertion was widely unsupported in the mid twentieth century when it was first declared by Turing. At this point in time intelligent machines and computer science were new inventions, recognised by very few individuals, and understood by fewer. Since the invention of computer processors, their speeds have been…

Salmonella infection in food is the one of the major causes of foodborne illnesses including fever, abdominal pain, diarrhea, and nausea. Thus, early detection of Salmonella contamination is important for our healthy life. Conventional detection methods for the food contamination have limitations in sensitivity and rapidity, thus the early phase detection has been difficult. Herein, we developed a bioelectronic nose using a carbon nanotube (CNT) field-effect transistor (FET) functionalized with…

CHAPTER 1 INTRODUCTION 1.1 BACKGROUND The catalytic converter was invented by Eugene Houdry, a French mechanical engineer and skilled in catalytic oil refining who lived in the United States around 1950. The invention of catalytic converter has a major role in controlling harmful emissions. When the paper of smog in Los Angeles was published, Houdry became anxious about the role of smoke stack and automobile exhaust in air pollution and established a company, Oxy-Catalyst. Houdry primary…
