1. INTRODUCTION TO CRYOGENICS
Cryogenics is the study of how to get to low temperatures and of how materials behave when they get there. Besides the familiar temperature scales of Fahrenheit and Celsius (Centigrade), cryogenicists use other temperature scales, the Kelvin and Rankine temperature scale. Although the apparatus used for spacecraft is specialized, some of the general approaches are the same as used in everyday life. Cryogenics involves the study of low temperatures from about 100 Kelvin to ....etc

Towards Optimal Color Image Coding using Demosaicing
Abstract—We introduce an optimal approach to color image compression using demosaicing. Accordingly, we propose an efficient algorithm for color image coding. In the encoder, a
mosaic of the primary colors is encoded instead of the full color image. This mosaic is considered as four different color channels that are compressed using subband transform coders. In the decoder, a demosaicing algorithm is applied to the decompressed channels to reconstruct the ....etc

Definition
Lyndsay Williams of Microsoft Research's Cambridge UK lab is the inventor of the Smartquill,a pen that can remember the words that it is used to write, and then transform them into computer text . The idea that it would be neat to put all of a handheld-PDA type computer in a pen, came to the inventor in her sleep . It's the pen for the new millennium, she says. Encouraged by Nigel Ballard, a leading consultant to the mobile computer industry, Williams took her prototype to the British Telecommunications Research Lab, where she w ....etc

ABSTRACT
BiCMOS technology is a combination of Bipolar and CMOS technology. CMOS technology offers less power dissipation, smaller noise margins, and higher packing density. Bipolar technology, on the other hand, ensures high switching and I/O speed and good noise performance. It follows that BiCMOS technology accomplishes both - improved speed over CMOS and lower power dissipation than bipolar technology. The main drawback of BiCMOS technology is the higher costs due to the added process complexity. Impurity profiles have ....etc

GSM Based Temperature Monitoring System

ABSTRACT
In recent years industrial automation and control systems are an integral part of an industry and hence the project temperature monitoring system is an important system in this state of affairs.
TMS aims at monitoring the temperature statistics in a factory, room etc, and controlling peripheral systems. It uses embedded technology from Intel Corporation and built for application in highly sensitive and critical systems.
Through the system we try to bring down the overhe ....etc

Abstract”
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed U ....etc
