BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, t ....etc

Implementation Of Zoom FFT in Ultrasonic Blood Flow Analysis

Introduction
An adequate blood flow supply is necessary for all organs of the body. Analysis of the blood flow finds its importance in the diagnoses of diseases. There are many techniques for analyzing the blood flow. These techniques are not affordable by the poor people because of their high expense. So we have implemented a technique called Zoom-FFT. This technique is simple and affordable to detect the blood clots and other diseases.

Basic Principles of Ultrasonic Testing



basic principles of ultrasonic testing Wave propagation

Longitudinal waves propagate in all kind of materials.
Transverse waves only propagate in solid bodies.
Due to the different type of oscillation, transverse wavestravel at lower speeds.
Sound velocity mainly depends on the density and E-modulus of the material.

Reflection and Transmission


As soon as a sound wave comes to a change in material ....etc

Ultrasonic methods enjoy the great capabilities in solving various problems associated with structural engineering and engineering materials. In this seminars, a host of research works and studies in this field carried out by the speaker will be presented to demonstrate the broad spectrum of their applications in aerospace engineering. Focus will be on nondestructive evaluation (NDE) and characterization of aerospace materials such as composites. Topics to be presented in the seminar include (1) 3-D imaging of damage in composites, (2) echo det ....etc
