Since tubes have numerous industrial applications, different attempts are focused on the Severe Plastic Deformation (SPD) processes of tubes. As an illustration, Tube Channel Pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of greater s...

This paper presents a new algorithm for conductivity imaging. Our idea is to extract more information about the conductivity distribution from data that have been enriched by coupling impedance electrical measurements to localized elastic perturbations. Using asymtotics of the elds in the presence of small volume inclusions, we relate the pointwise values of the energy density to the measured d...

We present a method for recognizing gesture motions based on elastic deformable shapes and curvature templates. Gestures are modeled using a spline curve representation that is enhanced with elastic properties: the entire spline or any of its parts may stretch or bend. The energy required to transform a gesture into a given template gives an estimation of the similarity between the two. We demo...

A novel method is proposed for elastic matching of two data volumes. A combination of mutual information, gradient information and smoothness of transformation is used to guide the deformation of another of the volumes. The deformation is accomplished in a multiresolution process by spheres containing a vector field. Position and radius of the spheres are varied. The feasibility of the method i...

The aim of the present study was to prepare an oral tablet from liquid yogurt by reforming the physical properties for easy transportation, long-term storage and also as a complementary dairy product in case of nutrient deficiency. The liquid fresh yogurt was lyophilized at -40°C and 0.03 mTor pressure. The dry powder was homogenized by a 12 mesh size sieve. Some tests such as Carr’s compressib...

The parameters of localization patterns emerging at the linear stage of work hardening are discussed in the frame of autowave concept. The stress-strain diagrams have been plotted for the test samples of metals exposed to active loading. It is found that the product of phase autowave velocity and length has the same order of magnitude as the product of elastic wave rate and the lattice constant...

ゼリーのような柔らかいもの(もしくは弾性体)の物理 ベースな変形シミュレーションは, 動画やテレビゲームなど の分野において重要である. これまで, コンピューターグラ フィックスの分野において, 弾性体の変形に関する非常に多 くの研究がなされてきた. 質量バネモデルや粒子ベースモ デル [19, 11, 1]は, テレビゲームのようなインタラクティブ なアプリケーションに用いられ, より正確な, すなわち連続 体力学に基づいた FEM(Finite Element Method, 有限要素 法)ベースのシミュレーション手法は, 主に正確さが要求さ れる動画に用いられている. FEM ベースのモデルは, 計算 コストが高いことが知られており, アダプティブ分割法など の多重解像度手法が提案されている [4, 8]. 一般的に多重解像度のアプローチを用いる FEM ベース の手法では,...
