Abstract


An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions, often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, can do many different tasks depending on programming. Embedded systems control many of the common devices in use today.
Since the embedded system is dedicated to specific tasks, design ....etc

Model Calibration and Prediction
abstract
The final project is an exercise in model calibration and prediction. The problem is very loosely based on a field example from the Basin and Range Province in the Western U.S. documented in USGS Professional Paper 1409-E. The project has four steps: model calibration, drawdown prediction, particle tracking, and presentation of results.

Your first task is to calibrate a steady-state model. You will work in groups; each group is asked to work independently. When ....etc

Development of Remote Waste Gas Monitor System
A remote waste gas monitor system is designed here for supervising factory chimney waste gas circumstance. This system has ARM as its core controller and collects the chimney pollutant indexes consisting of exhaust particulate,
sulfur oxides, carbon oxides as well as nitrogen oxides through different gas sensors. Global Positioning System(GPS) is used by the system to accurately obtain the position of the chimney. This information alongwith others is sent to the central control computer v ....etc

INTRODUCTION

What is embedded system?
A special-purpose computer system designed to perform one or a few dedicated functions.
It is a combination of both hardware and software.
The program instructions written for embedded systems are referred to as firmware, and are stored in read-only memory or flash memory chips
Applications such as digital watches ,mp4 players, traffic lights, factory controllers, or the systems controlling nuclear power stations etc.
