THE IMPACT OF TRANSPORTATION CONTROL MEASURES ON EMISSION CONTROL DURING THE OLYMPIC GAMES IN BEIJING

1. INTRODUCTION
1.1 GENERAL

Emissions from vehicles come from the by-products of the combustion process which takes place inside the vehicle when it moves. In addition to this, volatile organic compounds (VOC) also escape through fuel evaporation. As vehicle exhaust systems have improved, evaporative emissions have become a larger component of total vehicle VOC emissions

Home Security System
A Cornell University ECE 476 Final Project
by
Chun-Pai Jimmy Hsieh & Yang Cao

I n t r o d u c t i o n
This is a digital home security system with voice feature which can monitor room temperature, smoke, motion, and
windows & doors.
The goal of this project is to utilize the after-market parts and build an integrated home security system. Besides
traditional magnetic switch equipped on doors and windows, we have also incorporated temperature sensor, smoke
detectors, and motion sensor. Hence the ....etc

ENERGY AUDIT FOR BUILDINGS.
ABSTRACT
This topic provides an overview of the energy audit procedure suitable for commercial and industrial buildings. Energy audit has a vital role in the implementation of energy conservation measures. This enables them to meet the Energy Efficiency Standards.
There are several types of energy audits that are commonly performed by energy service engineers with various degrees of complexity. The key aspects of a detailed energy audit procedure and a systematic approach t ....etc

Emission Control Techniques
1. INTRODUCTION
The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons, carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants that could be emitted from an ....etc

ABSTRACT
Satellite crosslinks generally require narrower bandwidths for increased power concentration. We can increase the power concentration by increasing the cross page link frequency with the same size antenna. But the source technology and the modulation hardware required at these higher frequency bands are still in the development stage. Use of optical frequencies will help to overcome this problem with the availability of feasible light sources and the existence of eff ....etc

ABSTRACT
Fuel in any engine is burnt with air. Air is a mixture of gases and it contains approximately 78% nitrogen and 21% oxygen. Some of the oxygen is used to burn the fuel during the combustion process and the rest is supposed to just pass through unreacted. But when the peak temperatures are high enough for long periods of time, the nitrogen and oxygen combine to form a class of compounds called nitrogen oxides, collectively referred to as NOx. These compounds are one of the chie ....etc

Introduction
A Low-Cost Turbidity Meter for Underdeveloped Countries
Our project is a collaboration with an independent research project being conducted by senior civil and environmental engineering student James Berg.
� The goal of this project is to create a low cost turbidity meter for use in under developed countries.
� Real laboratory turbidity meters can cost over $1000.
� Our goal is to create a meter that costs between $50 and $75.
� Because we are using less expensive sensors, the accuracy of ou ....etc

ABSTRACT
The rapid development of electronic systems in automotive vehicles has been driven for decades
by constantly growing requirements of legislation for environmental protection, as well as rising
demands of the end-user to improve fuel economy, safety, driving comfort and driving
excitement. The manufacturers of mobile work machines also see themselves increasingly
confronted with these requirements. Can Robert Bosch GmbH use the technical experiences
from automobiles also in this area to efficiently dev ....etc
