in the present research, implementations of different computational geometry technologies in isogeometric analysis framework for computational fracture mechanics are investigated. nurbs and t-splines are two different computational geometry technologies which are studied in this work. among features of b-spline basis functions the possibility of enhancing a b-spline basis with discontinuities b...

in this paper by using concepts of graph theory, forces method and substructure ing method for analysis of structures, some methods have been introduced for optimal analysis of structures in a large scale, using substructuring method. planar rigid frames assuming linear behavior and small deformations, have been optimal analyzed, by using forces method. thus, a fortran power station computation...

Substructuring in the finite element method is a technique that reduces computational cost and memory usage for analysis of complex structures. The efficiency of this technique depends on the number of substructures in different problems. Some subdivisions increase computational cost, but require little memory usage and vice versa. In the present study, the cost functions of computations and me...

in this article, we propose and analyze a computational method for numerical solution of general two point boundary value problems. method is tested on problems to ensure the computational eciency. we have compared numerical results with results obtained by other method in literature. we conclude that propose method is computationally ecient and eective.

many diseases are related to cerebrospinal .uid (csf) hydrodynamics. therefore, understanding the hydrodynamics of csf .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...

This topic provides a forum for the presentation of research results and practical experience in the development of parallel programs. Advances in algorithmic and programming models, design methods, languages, and interfaces are needed to produce correct, portable parallel software with predictable performance on di↵erent parallel and distributed architectures. The topic emphasizes results that...

This paper presents a stereo active vision system which performs tracking tasks on smoothly moving objects in complex backgrounds. Dynamic control of the vergence angle adapts the horopter geometry to the target position and allows to pick it up easily on the basis of stereoscopic disparity features. We introduce a novel vergence control strategy based on the computation of \virtual horopters" ...
