The idea of compressed-air energy storage isn’t new, but cheap and plentiful energy has precluded much research. The low-tech explanation goes like this: excess energy from a power plant is used to run air compressors, which pump air into an underground cave, where it is stored under pressure. When released, the air powers a turbine, creating electricity. The initial energy used to force the air underground can come from wind, solar, nuclear or any source.

The technology could also help utilities meet their peak demand by collecting energ ....etc

Abstract
Sampling is the bottleneck for ultra-wideband (UWB) communication. Our major contribution is to exploit the channel itself as part of compressed sensing, through waveformbased pre-coding at the transmitter. We also have demonstrated a UWB system baseband bandwidth (5 GHz) that would, if with the conventional sampling technology, take decades for the industry to reach. The concept has been demonstrated, through simulation ....etc

Application of BPCS steganography to wavelet compressed video

Abstract: This paper presents a steganography method using lossy compressed video which provides a natural way to send a large amount of secret data. The proposed method is based on wavelet compression for video data and bit-plane complexity segmentation (BPCS) steganography. In wavelet-based video compression methods such as 3-D set partitioning in hierarchical trees (SPIHT) algorithm and motion-JPEG2000, wavelet coefficients in discrete wavelet transformed video are quantized i ....etc

Pumped hydroelectric and compressed air energy storage (CAES) are currently economic for utilities when relying on natural geologic formations and the cheapest, most abundant substances (i.e. elevated water and compressed air). In these situations the cost of energy storage capacity can be very low (<$5/kWh1) Unfortunately the scale and location-specific nature of energy storage in natural formations is likely to render it of limited benefit to small scale distributed renewables. Available pumped hydro and CAES capacities could prove small in r ....etc

CAES (Compressed Air Energy Storage)

What is Compressed Air Energy Storage

CAES refers to the compression of air to be used later as energy source.It can be stored during periods of low energy demand (off-peak),inorder to meet periods of higher demand (peak-load).
The first CAES systems were
constructed by Victor Popp in 19-th
centuary That was in 1870.

Compressed-air engine
abstract

A Compressed-air engine is a pneumatic actuator that creates useful work by expanding compressed air. They have existed in many forms over the past two centuries, ranging in size from hand held turbines up to several hundred horsepower. Some types rely on pistons and cylinders, others use turbines. Many compressed air engines improve their performance by heating the incoming air, or the engine itself. Some took this a stage further and burned fuel in the cylinder or turbine, fo ....etc

Introduction

In computer operating systems, demand paging is an application of virtual memory. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it (i.e., if a page fault occurs). This is an example of lazy loading techniques.

The compressed ROM file system (or cramfs) is a free read-only Linux file system designed for simplicity and space-efficiency. It is mainly used in embedded systems and small-footprint systems. Unlike a compressed image of a ....etc
