Gallium Nitride (GaN) based semiconductor to produce blue light

Name Instructor Course Date Producing Blue Light from GaN LEDs Introduction: This state of the art report will focus on light emitting diodes LEDs made from Gallium Nitride (GaN) based semiconductors to produce blue light. The light ought to be of 475 nm in wavelength for high performance and low-cost energy necessary for energy saving light bulbs. The problem this design seeks to address is the operational cost of lighting, longevity and durability compared to the tungsten incandescent lamp. The scope of the research behind this report will focus on how LEDs work by using Gallium Nitride based semiconductors to emit energy at wavelengths of 475 nm, which is the basic characteristic of blue light,...

how did i choose my major

Tutor Name Subject Date The reason I chose mechanical engineering as my major As a student, the choice of subjects is often informed by personal goals, ambitions and above all, passion. Choosing to major in a given area of specialization needs a serious deliberation and a great deal of an afterthought. As a student, the basis for choosing a major in mechanical engineering was solely based on my good performance in mathematics and science. As if this was nothing to go by, I had curiosity in design and evaluation of systems used in end product production. “ In some regions, engineers have combined multiple sources of power to fuel growing needs” (page 5) .The compelling desire to use...

Electrical enegineering in the field of Antennas and wave propagation and electromagnetism

Student’s Name Instructor’s Name Course Date Electrical Engineering in the field of antennas, wave propagation and electromagnetism Abstract Communication industry has seen tremendous development in the last decade which continues up to date. The developments partly involve bettering transmission and reception of waves that aid in communication. This means that the knowledge of the phenomena of wave propagation, electromagnetism and antenna design and application is a vital requirement for sustainable development in communication technology. This paper analyzes these phenomena and their application in mobile phones. A greater focus is given to Multi-input Multi-output (MIMO) technique...

If you were given funding for a small engineering project that would make your everyday life better, what would you do?

Name: Tutor: Course: Date: Engineering Project Water is an essential and basic need of every living thing on our planet. The conservation of this resource is thus paramount to make sure that it sustains life. Bathing is among the activities that wastes a lot of water; there is no means of determining the exact amount of water that is adequate. Additionally, the heating systems of water in many households are located far from the faucets. For this reason, it takes time for the water to heat up, and thus some water goes to waste while waiting for it to get warm. The challenge can be solved by installing the heating device directly on the taps or heating the water supplying pipes so that as the water...

engineering and public policy

Name Professor’s name Course Date Engineering and Public Policy Affairs between State and Federal gatherings frequently form environmental policy and laws. States can straight figure federal policy in the methods states, select to impose, or not administer, an environmental guideline. Federal directive of nonpoint basis water contamination is frequently quoted as feeble, in portion because sections often lack the enticement to apply federal principles, and state enforcers do not have the power to revoke state choices. In parts where the federal administration cannot straight intercede, local and state authorities have a very steady hand in determining the everyday result of the federal...

Dissertation Qinhao ShorterVersion 1

Introduction With the reduction in supply of conventional energy resources on this planet, it is critical and necessary to launch an investigation into renewable energy for a sustainable future. The United States Department of Energy (DOE) projects that the U.S. will receive 20 percent of the its energy supply from renewable energy by 2030. This is equivalently to around a 300 GW capacity. Recently in Europe, wind generators have been constructed offshore of Denmark. With the rise of renewable energy, the configuration of power systems will have to change accordingly. Therefore, more advanced control techniques are needed for addressing the issues occurred in a renewable or hybrid power system....

Structual design

Name of the Student Professor’s Name Structural Design Date Summary The main objective of the project was to design a simple bicycle pedal crank taking into account several structural and economical parameters. The structural parameters were related to the yield of pedal based on the rotations after subjected to combined loading and the shear stress generated thereof due to the impact. Given the stress conditions the principle angle derived was 45 degree for both with the Aluminium material and the Steel material. Therefore, the yield subjected to remain the same irrespective of the materials used to manufacture the bicycle crank. The Mohr's cycle represented the likely...

A Formal short Essay to join the IEEE-Eta Kappa Nu (Electrical and Computer Honor Society of the highest caliber)

Name Instructor Course Date A Formal short Essay to join the IEEE-Eta Kappa Nu The chance to become a member of IEE-HKN is very significant and interesting, and I suppose through my strong technical experience and little education experience I got as a junior year student in electrical engineering class, I will attain to a successful competitive candidate for this position. In every grade point average calculated in our class, I have always achieved excellent top grade. My position as a leader in a degree class of electrical engineering helps me to acquire the leadership skills and have a full understand and experience in learning and excelling in leadership. The key strengths that I enjoy...

Are there any difference between environmental ethics for humans and animals?

Name Teacher’s name Course Date Are there any difference between environmental ethics for humans and animals? One of the most fundamental questions that can be asked in Environmental Ethics is if there exists a difference between the environmental ethics for humans and animals. If an individual's answer is that human beings will perish if we do not limit our actions towards the environment, particularly nature, that that line of ethic is as ‘anthropocentric. This theory is interpreted to mean ‘human-centeredness,' and in this sense, this ethics must be regarded as anthropocentric. What this means is that human beings are superior to nature and therefore, as long as anything they are...
