Abstract: Forces applied to the implant due to human activity generate dynamic stresses varying in time and resulting in the fatigue failure of implant material. Therefore, it is important to ensure the hip prostheses against static, dynamic and fatigue failure. This study about two types of implants; the Austin Moore, cemented Thompson, and cementless Thompson hip replacements. The three dimensional solid models were built using AutoCAD 2007 software and then transferred to the finite element software (ANSYS Workbench).

Abstract: Photonic technology plays an important role in the development of new medical diagnostic and therapeutic instruments. Readily available compact solid-state lasers and various types of light sources allow one to examine tissues in a clinical environment using new and emerging photonic technologies. The objective of this work is to provide theoretical and experimental procedure of laser optoacoustic imaging to address breast cancer diagnosis using thermo-acoustic imaging principles, where the analytical simulation and experimental results have been represented.

Abstract:The purpose of this thesis is to serve as a general introduction to the blood flow physics and blood flow measuring methods, and as a comparative study and analysis for these methods. Blood flow is an important concept in medical field; it represents the function of the heart and the blood vessels of the body. Any abnormality in the heart or blood vessel will be expressed as change in the blood flow velocity from the assumed normal value.
