Compression is typically used for databases that have grown large enough to create a strain on system storage capacity. We argue here that database compression is attractive from a query processing viewpoint also and should therefore be implemented even when disk storage is plentiful. We study the compression ratio and query processing performance of a variety of compression algorithms, for dii...

A new paradigm is proposed which overcomes certain shortcomings in our current models of performer/computer interaction. The "Standard Model", in which the computer passively waits for performer input can be extended to include closed-loop behavior, both stable and unstable. In the time range typiied by the muscular and auditory subsystems, the existence Cadoz] of approximately linear spatially...

This paper describes a hierarchical algorithm for multi-resolution texture-based image enhancement for segmentation performance. The proposed algorithm is a modification of the steerable pyramid algorithm that has been successftully implemented for research in texture synthesis. ' We investigate in this paper the application of such a multiscale approach for image analysis to the problem of ima...

Carbon Nanotube Field Effect Transistors (CNTFET) are promising nanoscaled devices for implementing high performance, very dense and low power circuits. Most carbon nanotube field-effect transistors (CNTFETs) directly attach metal source/drain contacts to an intrinsic nanotube channel known as SBCNFET. When the gate oxide thickness is reduced, such transistors display strong ambipolar conductio...

Data mining is the procedure of extracting or taking out the information from the huge set of data. Web Mining is an important application of data mining, which is to extract knowledge from Web data including Web documents, hyperlinks, usage logs of web sites, etc. A Web Page contains many blocks such as content blocks, copyrights, privacy notes and advertisements. These blocks like advertiseme...

The IEEE 802.11-based WiFi wireless technology is one of the most promising technologies to provide ubiquitous networking access. The IEEE 802.11 working group has always strived to improve this wireless technology through creating new amendments to the base 802.11 standard. Recently, IEEE 802.11n amendment was created to enhance 802.11 for higher throughput operation. Not only new Physical Lay...

The design of double gate n-channel transistor named as junctionless vertical slit field effect transistor (JL VeSFET) is demonstrated in this paper. JLVeSFET is novel twin gate device which turns on and off depending upon the extension of depletion region from two gates inside the channel. It is observed that it offers very low OFF current with ideal subthreshold slope. JLVeSFET is compared wi...

UNLABELLED Identifying and masking repetitive elements is usually the first step when analyzing vertebrate genomic sequence. Current repeat identification software is sensitive but slow, creating a costly bottleneck in large-scale analyses. We have developed MaskerAid, a software enhancement to RepeatMasker that increased the speed of masking more than 30-fold at the most sensitive setting. A...

ARTICLE INFO In many applications it is required to control a large output load using a relatively low control force. To satisfy such purposes, device like mechanical power amplifier can be used which generally gives very fast response. As per the requirement of the system, power can be instantaneously available from continuously rotating drums of mechanical power amplifier. This project will f...
