Sound: A Basic Introduction What is Sound? Sound can be described as variations in density and pressure that expand in an elastic medium which could be a gas, liquid or solid body. The precondition for variations in pressure to be defined as sound is furthermore that in addition to the source of the sound and the transmitting medium, there should...

Abstract – Active street lighting has emerged as an essential factor in strategies for a resource-efficient economy and realization of sustainable growth. In the outdoor area, lights represent approximately 40 % of the total energy consumption at night and have much energy saving potential. If passers-by or vehicles, summarized as traffic elements, are not located near street lamps, it is...

Abstract Our theoretical interpretation shows that the electron density is condensed at 150°orientation and perhaps the reason for the high mobility of electron in graphene. To determine the above result, the constructed monolayer of graphene contains 40 carbon atoms with 48 bonds in between them and 16 hexagonal polyhedra and the bilayer of graphene has 80 atoms with 96 bonds...

Abstract The main aim of the project is to design a circuit which would allow the detection of light by using a photodiode and to critically assess in details how a light sensing circuit using a photodiode works to obtain a desired output. This is achieved by using a transistor Darlington pair, four resistors (2*330, 1k, 4.7k), one LED and...

Abstract Polymers represent a good alternative option for current metallic heat exchangers. That is due to their low weight ,cost, and volumetric-thermal-capacity. Polymers also considered as stable anti-corrosive material. Furthermore, fouling is less likely to stick on polymer surface compared to metals. However, polymers thermal conductivity is way less that metals (more than 100 times). Several researches in the literature...

Introduction What is the speed of light and what affects? This question has been asked for hundreds of years and the answer is simple. The speed of light is approximately 299,792,458 m/s (Las Cumbres Observatory, 2019). This answers the first part of the question, but what about the second part? What affects the speed of light? The purpose of this...

What are the consequences of different approaches to recording sound? Sound can be manipulated by various techniques. In Jack Walker's seminar, a variety of these techniques were explored such as creative microphone placements, processing and textures. He also discusses the effect of changing the equipment and space when recording. I will discuss a few of his approaches when recording. When...

Abstract When a body is in a state of motion, the total momentum is maintained, such that the product of mass and the velocity vector, until that moment when an external force is applied to it. This law is called the conservation of linear momentum, this principle somewhat corroborates the conservation of energy principle which states that energy is neither...

Abstract: Geothermal energy is one of the cleanest non-conventional energy source. A promising application of harnessed geothermal energy are ‘ground source heat pumps(GSHP)’. Ground source heat pumps can be used for both commercial applications as well as domestic applications, the key reason being the fact that they are highly energy efficient, energy saving capabilities and their environment friendliness. The use...

Lab Report 1. Introduction 1.1 Background Information: Newton’s second law of motion states that the acceleration of an object depends on two variables: the net force acting on the object and mass. The acceleration of an object is dependent directly upon the net force acting on the object, and inversely to the mass of the object. Acceleration is the total...

Abstract— Capturing photos in low light conditions is a difficult situation for photographers to get optimal image results. Low light conditions can occur at night, in the forest or in a dark room. The image quality in low light conditions is not good because the objects in the picture are lack of light which makes some objects blur and hard...

It is no secret that early scientific understandings were laden with racism guised as science. From the Valladolid Debates in the mid-16th century to slavery apologists in the 1850s. Even as recently as the late 20th century, scientific racism has been a dark cloud hanging over the scientific community. The concept of scientific racism has always existed, although it manifested...
