Risk - Return Relationship & the effect of Diversification

Introduction:

Sometimes your best investments are the ones you don't make. This is a maxim which best explains the complexity of making investments. There are many investment avenues available for investors today. Different people have different motives for investing. For most investors their interest in investment is an expectation of some positive rate of return. But investors cannot overlook the fact that risk is inherent in any in ....etc

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

Among the many environmental problems that offend and concern us perhaps none is as powerful and dramatic as water pollution. It is any undesirable change in physical, biological or chemical characteristics of water quality that adversely affects living organisms or makes water unsuitable for desirable use. Major sources that pollute water are domestic sewage and industrial effluents, acid rain etc. These are discharged into the rivers which in turn results in marine pollution.Marine pollution has been going on unnoticed for a long time by the ....etc

The photoacoustic effect - production of sound from light - may be exploited for detection and localization of gas leaks on the surface of otherwise sealed components. The technique involves filling the test component with a photoactive tracer gas, and irradiating the component to produce photoacoustic sound from any leak site where a tracer gas cloud forms. This presentation describes experiments utilizing 10.6-micron radiation from a carbon-dioxide laser with sulfur hexafluoride as a tracer gas. Here, photoacoustic sounds from a laminar plume ....etc

Chemical Mechanical Planarization (CMP) is an important process in semiconductor chip fabrication. In the CMP process, excess material is removed and the surface is planarized by the action of chemical and mechanical forces. Shallow Trench Isolation (STI) has become a key technology for device isolation in recent times. In this method, a shallow trench is made on the silicon wafer between active devices, silicon dioxide is deposited over the trench as well as the active area and the excess silicon dioxide is removed by CMP. The oxide remaining ....etc
