This paper presents a high-speed low-complexity Field Program Gate Array (FPGA) design and implementation of the lossless Lempel-Ziv-Welch (LZW) algorithm on Xilinx Virtex-E device family for selfadapting Radar video echo data acquisition Applications. A multi-channel self-adaptive variable sampling rate data acquisition system based on FPGA and I2C bus is introduced. By writing the frame data ...

paulownia is one of the fast-growing species that was attended to supply industrial requirement in recent years. the application of this species is limited because of low density, so wood modification via compression and densification is an effective method. for this purpose, the paulownia boles were prepared from shastkalateh forest and cut into blocks with 60×20×20 mm dimension. the variable ...

Image compression is dissimilar than compressing other unprocessed binary data. Obviously, general purpose compression techniques deliberated for raw binary data can be used to compress images, but the result is not the finest one, because of the variations in statistical property of image. Statistical properties of image must be completely exploit by encoders to obtained efficient image compre...

In this study, the buckling response of homogeneous circular plates with variable thickness subjected to radial compression based on the first-order shear deformation plate theory in conjunction with von-Karman nonlinear strain-displacement relations is investigated. Furthermore, optimal thickness distribution over the plate with respect to buckling is presented. In order to determine the distr...
