هدف: طی سال‌های اخیر دولت کارآفرین با تأکید بر بازآفرینی به‌‌عنوان یکی از رویکردهای مدیریت دولتی نوین در بسیاری کشورهای جهان مطرح شده است که این موضوع نیاز به شناسایی عوامل مؤثر ایجاد و توسعه شکل دارد. بنابراین، پژوهش حاضر هدف پیشران‌های انجام است.طراحی/ روش‌شناسی/ رویکرد: راهبرد تحلیل محتوای کیفی رویکرد قیاسی چارچوب پژوهشی اسنادی استفاده همچنین، تدوین کدگذاری مناسب برای اجرای روش فراترکیب است....

Interactive web-based computer simulations are needed by the medical community to replicate the experience of surgical procedures as closely and realistically as possible without the need to practice on corpses, animals and/or plastic models. In this paper, we offer a review on current state of the research on simulations of surgical threads, identify future needs and present our proposed plans...

The macroscopic modelling of in-plane elastic behaviour of composite solids made with regular orthotropic texture is the object of the present study. At the macro-scale, the effect of heterogeneity can be included by adopting an homogenisation toward a generalised continuum on which specific finite element codes are based. As an alternative, a specific rigid element approach has been recently p...

This article addresses the dynamic modeling of geometrically exact sliding Cosserat rods. Such systems need to consider non-material time-varying domains which Lagrangian view point solid mechanics is inappropriate. In here presented, we use model inextensible Kirchhoff rods along a domain whose time variations are not necessarily imposed but governed by dynamics, i.e. depend on configuration r...

We generalize substructuring methods to problems for functions f : Ω → M , where Ω is a domain in R and M is a Riemannian manifold. Examples for such functions include configurations of liquid crystals, ferromagnets, and deformations of Cosserat materials. We show that a substructuring theory can be developed for such problems. While the theory looks very similar to the linear theory on a forma...
