Analysis of Optical Imaging Technologies

PAI is a relatively new imaging modality which displays optical absorption contrast with a high resolution at depths of up to a few centimetres. Tissue is illuminated using short laser pulses and ultrasound waves are generated within the tissue upon optical absorption. An image is formed of the optical absorption contrast based on the arrival […]

Analysis of Safeguarding Measures

CHAPTER 1 INTRODUCTION BACKGROUND OF STUDY Machines are very dangerous to workers and are commonplace in many industries. The safety, health and welfare of workers are of utmost importance, especially where machine and moving parts of machines are involved. The employers have a legal duty to take reasonable care of the safety of the workers […]

Analysis of S-d Exchange Interactions in Dilute Cu-mn Alloys

Share this: Facebook  Twitter  Reddit  LinkedIn  WhatsApp   Phenomenological analysis of the s-d exchange interactions in dilute Cu-Mn alloys at helium temperatures AL-Jalali, M. A. Abstract: The S-d exchange interactions in dilute Cu-Mn alloys was studied on concentration ( C ) varying between 10.5 and 2081.8 ppm of Mn in Cu within the ( 0.03K – 4.2K ) temperature range. Using electrical resistivity […]

Analysis of SIF Intrinsic Dynamics

Abstract. It was recently found that spectral solar incident flux (SIF) as a function of the ultraviolet wavelengths exhibit 1/ftype power-law correlations. In this study, an attempt was made to explore the SIF intrinsic dynamics versus a wider range of wavelengths, from 115.5nm to 629.5nm. It seemed that the intermittency of SIF data set was very […]

An Experiment Determining Lift from Pressure Distributions

Share this: Facebook  Twitter  Reddit  LinkedIn  WhatsApp   Abstract The experiment described in this report used a pressure distribution over a NACA 0012 airfoil to determine the lift and moment coefficient about the quarter-chord on that airfoil. Lift is one of the most important and governing forces acting on a body moving in a fluid. The calculation of lift and drag is at […]

An x-ray machine

How does an X-ray machine work? An X-ray machine is essentially a camera instead of visible light, however, it uses X-rays to expose the film. X-rays are like light in that they are electromagnetic waves, but they are more energetic so they can penetrate many materials to varying degrees. When the X-rays hit the film, […]

Application of Electricity to Transistors

Intro: A transistor is an electronic device that has three terminals where a small current at one terminal is used to control currents at the other terminals. Before transistors were invented by Bardeen and Brattain in 1947, thermionic valves (vacuum tubes) were the devices that were able to amplify current signals within a circuit. The […]

Applications of Engineering Materials in Aerospace

In this project I will discuss in details the applications of engineering materials in Engineering and its many application in the Aerospace and Formula 1. Materials are key in engineering because the correct materials are needed to meet the needed of the environment that they are meant for use in. In aerospace the materials that […]

Applications of Hard X-ray Photoelectron Spectroscopy

Applications of Hard X-ray Photoelectron Spectroscopy to bulk materials Jingru Chi ABSTRACT X-ray Photoelectron Spectroscopy is a powerful, relevant and non-destructive method for studying atoms, molecules and surfaces [1]. However, investigations are limited to atoms, molecules and surfaces since low energy electrons limit the depth resolution, resulting in three-dimensional bulk state cannot be detected. Hard […]

Applications of Ultrasound in Medicine

AB Assessment – Using Waves Introduction Ultrasound is a sound wave with an oscillating pressure wave with frequencies ranging from 20 kHz until approximately 200 MHz. These frequencies are not audible to humans. Ultrasonic devices are used to detect objects and measure the distance between them. Ultrasound has been more frequently used in medical imaging […]
