The development of an efficient compression scheme to process the Arabic language represents a difficult task. This paper employs the dynamic Huffman coding on data compression with variable length bit coding, on the Arabic language. Experimental tests have been performed on both Arabic and English text. A comparison is made to measure the efficiency of compressing data results on both Arabic a...

The compression chamber of a hermetic reciprocating compressor is, normally, formed by a cylinder and a piston which present a constant clearance during the piston displacement inside the compression chamber. This configuration has the advantage of a good sealing, however, during the most part of compression, the pressure difference between compression chamber and internal compressor ambient is...

In this work, the simulation results from a program developed for the three-dimensional analysis of compression molding of thermoset composites were compared to the experimental results of an actual molded thermoset sample. The program predicts the flow pattern, fiber orientation, fiber length distribution, curing of the resin and mechanical properties. The comparison between simulation and exp...

Sewage sludge proves to be difficult to dewater due to its composition and biological nature, and it is unsuitable for disposal with high moisture content. In the present work, sewage sludge is dewatered by the thermal compression, which shows unique separation advantages of various materials, and the effects of applied temperature and pressure on the dewatering performance are investigated. Th...

Stored process data in the form of high fidelity time trends are a resource for data-driven process analyses such as statistical monitoring, minimum variance control loop benchmarking, fault detection, data reconciliation and development of inferential sensors. However, many commercial data historians compress the data before archiving it and a question therefore arises of how useful the compre...

ION AS A NATURAL PROCESS OF MENTAL COMPRESSION Eddie Gray & David Tall Mathematics Education Research Centre University of Warwick, Coventry, CV4 7AL, UK

Data has a fairly important meaning, because it contains the information needed. Besides being important, process of data exchange and storage certainly requires space high costs. For this reason, compression is an interesting topic for continuous research. The success previous research in obtaining optimal compression, will be more interesting, if tested on Lossless Lossy Compression Methods, ...

Work had always been under process to design efficient algorithms for image compression based on various conventional and soft computing methodologies. This paper aims at exploring the application of multi layered perceptron (MLP) feed forward neural networks (FFNN), wavelet transforms and their combination architectures for image compression. Initially two neural network architectures for imag...

a newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. the main fuel would be natural gas and diesel oil as pilot injection. the importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...

Delta compression is the process of comparing two files to produce a set of instructions that will convert one file into the other. Storing or transmitting a delta file rather than the entire new file can offer significant efficiency gains. However, the different aspects of delta compression efficiency, like many problems in computer science, can rest at different ends of a balance. There does ...
