As it is widely supported, by compressing the cells that are transmitted over the links of an ATM network, you can significantly increase the effectiveness of the whole network. One of the main problems with networks that are using such low level compression, is that they need a special Connection Admission Control (CAC) Algorithm which will be capable of taking advantage of the increase of the...

Quantum-dot (QD) lasers exhibit many useful properties such as low threshold current, temperature and feedback insensitivity, chirpless behavior, and low linewidth enhancement factor ( H-factor). Although many breakthroughs have been demonstrated, the maximum modulation bandwidth remains limited in QD devices, and a strong damping of the modulation response is usually observed pointing out the ...

Range images (depth maps) are seeing increased usage in a variety of application areas including entertainment, industrial automation, inspection, remote sensing, and military tactical planning. As the corpus of range imagery increases in size and the need to communicate such images over fixed-bandwidth channels increases, the compression of range data deserves investigation. Since the geometry...

Satellite image Compression reduces redundancy in data representation in order to achieve saving in the cost of storage and transmission image compression compensates for the limited on-board resources, in terms of mass memory and downlink bandwidth and thus it provides a solution to the (bandwidth vs. data volume) dilemma of modern spacecraft Thus compression is very important feature in paylo...

Abstract : Bandwidth conservation is an important issue in case of multimedia communication. Uncompressed multimedia (graphical, audio and video) data requires considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds and digital communication system performance, it demands for data storage capacity and data-transmission bandwidth...

This document describes a method to improve the bandwidth utilization of network paths that carry multiple streams in parallel between two endpoints, as in voice trunking. The method combines standard protocols that provide compression, multiplexing, and tunneling over a network path for the purpose of reducing the bandwidth used when multiple streams are carried over that path.

FPGA uses a promising technology for developing high-performance embedded systems. Reconfiguration systems widely uses Field Programmable Gate Arrays and configured using bitstream often loaded from memory. The Bitstream Compression and Decompression technique reduce the size of the bitstream and also limits the memory constraint. The Compression mechanism improves the access bandwidth for comm...

The main process involves in medical image compression algorithms is encoding information using lesser amount of bits than the original representation used. Image compression is useful as it reduces the load of expensive resources and their consumption. These resources include transmission bandwidth, disk space etc. Compression may be lossy or lossless. But we avoided the concept of lossy compr...

Abstract. This paper proposes a new method that combines checkpointing methods with error-controlled lossy compression for large-scale high-performance full-waveform inversion (FWI), an inverse problem commonly used in geophysical exploration. combination can significantly reduce data movement, allowing reduction run time as well peak memory. In the exascale computing era, frequent transfer (e....

Since digital images require a large space on the storage devices and the network bandwidth, many compression methods have been used to solve this problem. Actually, these methods have, more or less, good results in terms of compression ratio and the quality of the reconstructed images. There are two main types of compression: the lossless compression which is based on the scalar quantization a...
