run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
In this paper, we present an experimental work using a MOCAP system and an iterative minimization technique to compute damping parameters and to measure their contribution for the simulation of cloth in free fall movement. Energy damping is an important phenomenon to consider for the 3D simulation of warp and weft materials, since it has a great influence on the animation realism. This phenomen...
Denim jeans, dyed with natural or synthetic indigo, are the most popular garments worn by individuals of all ages and approximately one billion pairs of jeans are produced per annum. Traditionally, denim has been woven with cotton in a warp face twill weave, in which the warp is blue whereas the weft is white. Dyeing is usually performed with pure indigo, or indigo combined with a sulfur dye to...
the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...
this study investigated the functions, types and frequencies of code switching in the teachers and students discourse in elt classrooms. to this end, the participants of this study including two groups of teachers and students were selected. the first group of participants were two efl teachers teaching general english courses (at two different levels of proficiency) in an institutional program...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
Abstract 3D meso-structural composites with three layers were constructed using modeling software Pro/E, and the static anisotropic characteristics of under lateral compression in warp weft directions simulated by finite element analysis ANSYS. The mechanical properties predicted analyzing stress strain distribution fiber resin load. then analyzed. Results showed that property was anisotropic, ...
Natural silk fabric is directly derived from insect produced cocoons containing large volumes of fibroin protein. The fibres secreted by the two glands Bombyx mori are smooth and soft form structural center silk. Sericin a coating with an amorphous structure that bonds strands. It component hardening raw thread. as we know it low mass per unit area. level friction textile materials depends on n...
This article employs a metaphor of weaving in order to analyze, both historically and critically, the art and science of occupational therapy. To spark reflection about where occupational therapy has been, is now, and would like to progress as the new century approaches, the article is thematically organized around the profession's two most fundamental convictions. These convictions are termed ...
