The advent of noisy-intermediate scale quantum computers has introduced the exciting possibility achieving speedups in machine learning tasks. These devices, however, are composed a small number qubits, and can faithfully run only short circuits. This puts many proposed approaches for beyond currently available devices. We address problem efficiently compressing loading classical data use on co...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...

Quickly transmitting large datasets in the context of distributed computing on wide area networks can be achieved by compressing data before transmission. However, such an approach is not efficient when dealing with higher speed networks. Indeed, the time to compress a large file and to send it is greater than the time to send the uncompressed file. In this paper, we explore and enhance an algo...

Data compression has important application in the field of file storage and distributed systems. It helps in reducing redundancy in stored or communicated data. This paper studies various compression techniques and analyzes the approaches used in data compression. Furthermore, information theory concepts that relates to aims and evaluation of data compression methods are briefly discussed. A fr...

Sevt,ral methods are presented for adaptive, invertible data complression in the style of Lempel’s and Ziv’s first textual substitution proposal. For the first two methods, the article describes modifications of McCreight’s suffix tree data strut ture that support cyclic maintenance of a window on the most recent source characters. A percolating update i:; used to keep node positions within the...

Three-dimensional visualization techniques are becoming an important tool for medical applications. Computer generated 3D reconstructions of the human skull are used to build stereolithographic models, which can be used to simulate surgery or to create individual implants. Anatomy-based three-dimensional models are used to simulate the physical behaviour of human organs. These 3D models are usu...

A novel data compression scheme is presented. The method is very suitable for black and white images, and it can generate a compression factor of eight; in general the bitmap is optimized for an arbitary number of colors and not only for unused information contained in a conventional bitmap with 2 bits per pixel. This compression method can be incorporated with other compression methods; it is ...

This paper presents LZAC, a new universal lossless data compression algorithm derived from the popular and widely used LZ77 family. The objective of LZAC is to improve the compression ratios of the LZ77 family while still retaining the family’s key characteristics: simple, universal, fast in decoding, and economical in memory consumption. LZAC presents two new ideas: composite fixed-variable-le...
