Development of computer technology offers ever more elaborated and some novel mathematical modeling methods for description of materials response to rolling. Research in this field has been undertaken by a number of experts who proposed numerous particular models 1-7 . Using these models can provide detailed information on changes in thermomechanical variables during rolling and enable the pred...

Leukocyte rolling is an important step for the successful recruitment of leukocytes from blood to tissues mediated by a specialized group of glycoproteins termed selectins. Because of the dynamic process of leukocyte rolling, binding of selectins to their respective counter-receptors (selectin ligands) needs to fulfill three major requirements: (1) rapid bond formation, (2) high tensile strengt...

Motivated by rolling adhesion of white blood cells in the vasculature, we study how cells move in linear shear flow above a wall to which they can adhere via specific receptor-ligand bonds. Our computer simulations are based on a Langevin equation accounting for hydrodynamic interactions, thermal fluctuations, and adhesive interactions. In contrast to earlier approaches, our model not only incl...

A methodology based on multi-weights neural network (MWNN) is presented to identify faults of rolling bearing. With considerations of difficulties in analyzing rolling bearing vibration data, we analyzed how to extract time domain feature parameters of faults. Further, the time domain feature parameters extracted from fault signals are utilized to train multi-weights neural network for achievin...

Group therapy is a central treatment modality for behavioral health disorders such as alcohol and other drug use (AOD) and depression. Group therapy is often delivered under a rolling (or open) admissions policy, where new clients are continuously enrolled into a group as space permits. Rolling admissions policies result in a complex correlation structure among client outcomes. Despite the ubiq...

the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on...

ZnTiCu (zinc-titan) sheets with approximately 0,1% Cu and 0,1% Ti content are very widely used in the construction industry for roof covering, gutters, drain pipes, facing linings, connections, window shelves, decorative elements on roofs, art products, etc. Data on the production technology of zinc-titan alloy sheet and on its forming properties are very scarce and unreliable. Therefore they m...

cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. in this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...
