SEMIANR REPORT ON Giant Magnetoresistance Effect



ABSTRACT
The Giant Magnetoresistance Effect was discovered in 1988. It took around 10 years of laborious research for its first fruits to be ripened. But once they were on, they started to cause unprecedented increase in the storage capacity of hard disks. Another area of application is the primary memory. The seminar presents the details of this discovery and the impact it had on the industry. ....etc

Fuel plus air equals motion that's the basic science behind most of the vehicles that travel on land, over sea, or through the sky. Cars, trucks, and buses turn fuel into power by mixing it with air and burning it in metal cylinders inside their engines. Exactly how much fuel and air an engine needs varies from moment to moment, depending on how long it's been running, how fast you're going, and a variety of other factors. Modern engines use an electronically controlled system called fuel injection to regulate the fuel-air mixture so it's exac ....etc

A four-stroke engine (also known as four cycle) is an internal combustion (IC) engine in which the piston completes four separate strokes while turning a crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:

Intake: This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum p ....etc

GMR sensors

Introduction
GMR - Giant Magnetoresistance
Discovered in the late 1980s
Very large resistance changes in materials with magnetic field
The GMR effect states significant decrease in electrical resistance in the presence of a magnetic field.
Size of magnetic field is 10-100 Oe

Features
High sensitivity for low magnetic fields
Measures field parallel to its sensitive axis
Good signal-to-noise ratio
High spatial resolution
Frequency independent sensitivity
Low cost, Less p ....etc

The giant wheel is displayed using circular rings. Rotation effects are provided for giant wheel. The swing action is employed for the Columbus boat. The Roller Coaster moves on a specified track. Tracks are created using the Bezier curve functions with a set of defined control points. The entire scene is placed inside a textured mapped cube called SkyBox. This gives a realistic effect of the sky. The software also includes a first person movement where the viewer can move anywhere in the scene. Mouse drag is support ....etc

The Rankine cycle is a model that is used to predict the performance of steam turbine systems. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work. The heat is supplied externally to a closed loop, which usually uses water as the working fluid. It is named after William John Macquorn Rankine, a Scottish polymath and Glasgow University professor. ....etc
