A new approach to generate a pattern for any object of binary image is proposed. One of important compression techniques of any monochrome images without losing the information is chain code encoding principle. It is segmenting the connected component of each region at point of boundary. The boundary is located by selecting the point with coordinates and then transmitted. This continues to reac...

Die corner filling is very important in tube hydroforming process. Definition of the internal pressure path is a key factor in improving the corner filling.  However, the factors that cause improvement of corner filling are still unclear. In this paper, effect of bilinear pressure path on corner filling in hydroforming of tube in box-shape die is studied using both finite element simulation and...

SystemVerilog Assertions (SVA) can be used to implement relatively complex functional coverage models under appropriate circumstances. This paper explores the issues and implementation of such a functional coverage model to demonstrate both the capabilities of SVA coverage and illustrate coding techniques which can also be applied to the more typical use of SVA coverage, which is to specify key...

Single-crystals of CsCeF5 were synthesized hydro-thermally. The crystal under investigation was twinned by pseudo-merohedry with a twofold rotation around the c axis as an additional twinning operation. The crystal structure is built of layers of distorted edge- and corner-sharing CeF8 square-anti-prisms. The Cs(+) cations are located between the layers and exhibit coordination numbers of nine....

A Fourier domain watermark localized near image feature points is presented in an attempt to make an invisible watermark that is robust to common image processing attacks. Finding robust feature points allows for localized watermarking to be detected after attacks. The feature points are found using the Harris corner detector. Points that respond greatest to the Harris corner detector will ofte...

The crack propagation evolution of carbonaceous mudstone under the action dry-wet cycles is an important cause unstable failure this type slope. This paper attempts to reveal mechanism mesocrack and macrocrack in from chemical, physical, mechanical perspectives. Firstly, soaking solution during was extracted for ion concentration test analyze chemical reactions mudstone. Then, CT scans were per...

3D video can be represented by color 2D video sequence accompanied by gray-scale dense depth map (depth image) sequence. In this paper, we describe a novel method for intraframe compression of the depth modality of such representation. Our method takes into account specific features of depth images, i.e. the presence of large smooth regions delineated by sharp discontinuities (edges). For such ...
