The Hamming Codes based Data Compression (HCDC) algorithm is a lossless data compression algorithm based on the concept of the error-correction Hamming Codes. The HCDC algorithm has been used successfully in a number of text compression applications providing a competitive compression ratio to existing well-known text compression algorithms. This paper describes an enhanced version of the HCDC ...

Fractal image compression uses the property of selfsimilarity in an image and utilizes the partitioned iterated function system to encode it. Fractal image compression is attractive because of high compression ratio, fast decompression and multi-resolution properties. The main drawback of Fractal Image Compression is the high computational cost and is the poor retrieved image qualities. To over...

In this paper, four different nondestructive testing (NDT) methods and static bending tests were done on poplar (Populus ussuriensis Kom.) and birch (Betula platyphylla Suk.) Laminated Veneer Lumber (LVL). The effects of compression ratio on the modulus of elasticity (MOE) and modulus of rupture (MOR) of LVL with vertical load and parallel load were investigated. There were four compression rat...

Database for Online Transaction Processing (OLTP) application is used by almost every corporations that has adopted computerisation to support their operational day to day business. Compression in the storage or file-systems layer has not been widely adopted for OLTP database because of the concern that it might decrease database performance. OLTP compression in the database layer is available ...

BACKGROUND: Agricultural machinery is the main consumer of liquid petroleum-product fuel in countryside Republic Sakha (Yakutia). Even partial transition to biogas would reduce consumption fuel, this regard, first all, it necessary determine compression ratio for agricultural fueling. A number experimental works demanded carry out different compositions.
 AIMS: Determination composition fu...

In the recent period, image data compression is the major component of communication and storage systems where the uncompressed images requires considerable compression technique, which should be capable of reducing the crippling disadvantages of data transmission and image storage. In the research paper, the novel image compression technique is proposed which is based on the spatial domain whi...

To effectively utilize the storage capacity, digital image compression has been applied to numerous science and engineering problems. There are two fundamental image compression techniques, either lossless or lossy. The former employs probabilistic models for lossless storage on a basis of statistical redundancy occurred in digital images. However, it has limitation in the compression ratio and...
