CHAPTER 1
INTRODUCTION
In certain application fields where image processing is involved, the use of spectral information in the visible (VIS) and near infrared (NIR) range is critical. The systems for spectral measuring can be classified according to their spectral resolution or their spatial resolution. Narrowband hyper spectral systems are usually based on point spectrometers or linear spectrometers. These systems can measure many precise narrow spectral bands of a point light source or a line source, in the VIS and NIR ranges and beyond. O ....etc

B.Tech (CSE)
ABSTRACT
In todayâ„¢s fast world, man is in a situation where he has to compete against machines. Due to this stress of a mechanical life, the human body is subjected to various levels of trauma. The organ most affected is the heart. Heart attacks are becoming so common now a day. The percentage of people affected is increasing by the day. This heart attack is mainly caused due to improper diet with excessive cholesterols and l ....etc

Efficient and Secure Content Processing and Distribution by Cooperative Intermediaries
INTRODUCTION
IN order to enhance the performance of content distribution
networks (CDNs), several approaches have been
developed based on the use of content management services
provided by intermediary proxies. In most of these approaches,
content caching is the main service provided by
proxies , , , . That is, instead of asking a content
server for contents upon each client request, a proxy first
checks if these contents ....etc

Abstract
Organic thin-film transistors OTFTs have received considerable attention recently because they can be fabricated at reduced temperature and potentially reduced cost compared to hydrogenated amorphous silicon thin-film transistors. Low fabrication temperature allows a wide range of substrate possibilities and makes OTFTs an attractive technology for many low-cost electronics applications, particularly those that require or may benefit from flexible polymeric substrates such as rf identification tags, smart cards ....etc

Abstract:
Haptic technology, or haptics, is a feedback technology which takes advantage of a user's sense of touch by applying forces, vibrations, and/or motions upon the user. This mechanical stimulation may be used to assist in the creation of virtual objects (objects existing only in a computer simulation), for control of such virtual objects, and for the enhancement of the remote control of machines and devices (teleoperators). It has been described as (doing) for the sense of touch what computer graphics does for vision . how ever comp ....etc

Human power generation in space Rutgers symposium on lunar settlement

Introduction

Assuming 40% of a 2000 Calorie/day diet is used for physical activity, 
3.35 MJ of energy/day is used to perform activities.
Approximate mechanical energy performed during some physical activities:
Walking/Running (0.49 J/kg*step)
Stair climbing (1.96 J/kg*step)
Cycling (88.2 J/rev)
Lifting (9.8 J/kg*m) ....etc

CHAPTER 1.
INTRODUCTION
¢ This section provides a brief introduction to needs of implementing IP based 4G network.
Virtually all papers with the title ˜Beyond 3G Mobile Networks™ consider IP as the final means of integrating access networks from any technology”wireless or fixed” and the, equally IP-based, core network. This migration from traditional circuit-switched networks toward a packet based IP network infrastructure adds considerably to the pressure to provide commercialized services in this network. Although ....etc

This system is mainly used for security purpose in offices and industries. Nowadays in some companies anybody can enter inside the company in the name of other employee. Because the company canâ„¢t check the person photo at every time. After that person entered inside the company, if he does any unwanted activities ad the person came outside the company, nobody can find out that person. We solved this problem in our project by using RF proximity card and video camera. Whenever the person enters to the campus he has swipe the ID card. That t ....etc

AUTOMATIC TRANSMISSION IN CARS
ABSTRACT
The modern automatic transmission is by far, the most complicated mechanical component in today's automobile. Automatic transmissions contain mechanical systems, hydraulic systems, electrical systems and computer controls, all working together in perfect harmony which goes virtually unnoticed until there is a problem. This article will help you understand the basic of the transmission, about automatic transmission, differences between manual and automatic transmission, the concept ....etc
