Tubular channel angular pressing (TCAP) is a recently invented novel severe plastic deformation technique for producing UFG tubes. Plastic deformation analysis using the finite element method (FEM) was carried out to investigate the effects of trapezoidal channel geometry on strain inhomogeneity index (SII), strain level and required load compared to previously used channel geometries. The resu...

Polar codes are one of the best linear block that capacity achieving and incorporating along with it a simplified encoding decoding routines. Successive cancellation (SC) algorithm is predominantly used algorithms due to its low complexity. It has broad scopes for hardware architecture design reformulation. For polar code, trade-off among long latency silicon area SC bottleneck high throughput ...

Abstract A method based on the contour coefficient and image processing technology is proposed to better identify visual elements. This article takes of as recognition feature, summarizes methods target feature extraction, shape representation, similarity studies edge preserving denoising, simplification description methods, matching methods. problem can usually be solved by filling out a form....
