The distribution and magnitude of the shear stress at interface between grout a compression anchor rod rock are strongly affected by Poisson effect. A new analytical equation influence coefficient effect is proposed to quantitatively evaluate on interfacial stress. When considered, from neutral point bearing plate increases, curve becomes steep. However, far low, smooth. Overall, leads more non...

Probabilistic shaping (PS) has been widely studied and applied to optical fiber communications. The encoder of PS expends the number bit slots controls probability distribution channel input symbols. Not only studies focused on but also most works communications have assumed source uniformity (i.e. equal marks spaces) so far. On other hand, information is in general nonuniform, unless bit-scram...

Recent developments in mesh modelling of images have provided algorithms that can achieve accurate and efficient image representations without the high computational cost associated with earlier optimisationbased methods. Hence non-uniform sampling of images combined with the use of irregular content-based meshing has provided a successful basis for recent developments in image compression tech...

We propose a nonlocal continuum model to describe the size-dependent superelastic effect observed in recent experiments of single crystal Cu-Al-Ni shape memory alloys. The model introduces two length scales, one in the free energy and one in the dissipation, which account for the size-dependent hardening and dissipation in the loading and unloading response of micro- and nanopillars subject to ...

In this paper, the literature published on lossy compression of seismic data using the popular subband coding technique is reviewed. The strong links between subband coding, transform coding, and the more recent discrete wavelet transform coding are described. The performance of seismic data subband coding depends on the proper choice of lter bank and frequency partitioning in the subband domai...

Most image and video compression algorithms that have been proposed to improve picture quality relative to compression efficiency have either been designed based on objective criteria such as signal-to-noise-ratio (SNR) or have been evaluated, post-design, against competing methods using an objective sample measure. However, existing quantitative design criteria and numerical measurements of im...

Constant pressure and temperature molecular dynamics techniques have been employed to investigate the changes in structure and volumes of two globular proteins, superoxide dismutase and lysozyme, under pressure. Compression (the relative changes in the proteins' volumes), computed with the Voronoi technique, is closely related with the so-called protein intrinsic compressibility, estimated by s...

Image compression is a crucial step in image processing area. Image Fourier transforms is the classical algorithm which can convert image from spatial domain to frequency domain. Because of its good concentrative property with transform energy, Fourier transform has been widely applied in image coding, image segmentation, image reconstruction. This paper adopts Radix-4 Fast Fourier transform (R...

We use molecular statics simulations with the tight-binding potential to analyze stress evolution in nanosize square prismatic gold specimens of different aspect ratios (length/width) deformed in either simple tension/compression or tension/compression. In the former case atoms on end faces are displaced axially but are free to move laterally, and in the latter case atoms on end faces are restr...

An accurate nonlinear hygrothermal-electro-elastic (HTEE) buckling analysis of piezoelectric fiber-reinforced composite cylindrical shells subjected to the coupled loading effects axial compression and hydrostatic pressure was established by considering nonuniform prebuckling effect. Nonlinear governing equations were derived based on higher-order shear deformation theory Novozhilov’s shell the...
