With the increasing popularity of time-sensitive network applications and gradual integration Tactile Internet into people’s lives, how to ensure ultra-low latency has become a demand challenge for performance. Therefore, it is extremely important analyze performance Internet. In this paper, we propose an analytical model based on deterministic calculus (DNC) quantitatively derive end-to-end bo...

زمینه و هدف: تغییرات ایجاد شده در واحد عملکردی عضله-استخوان در زنان یائسه ی استئوپروتیک، تغییراتی را در استراتژی های کنترلی به همراه خواهد داشت. هدف مطالعه ی حاضر بررسی قدرت عضلات و شاخص های پایداری ایستا، پویا و عملکردی در زنان یائسه ی استئوپروتیک و مقایسه آن با زنان یائسه غیر استئوپروتیک (سالم و استئوپنیک) بود. روش کار: 71 زن یائسه ی داوطلب (48-65 سال) بر حسب score-t به سه گروه سالم، استئوپن...

The concept of configuration of groups which is defined in terms of finite partitions and finite strings of elements of the group is presented by Rosenblatt and Willis. To each set of configurations, a finite system of equations known as configuration equations, is associated. Rosenblatt and Willis proved that a discrete group G is amenable if and only if every possible instance of its configur...

ab initio calculations were employed to investigate nitrogen inversion as a configuration change that can supply an infinitely useful switchable control mechanism for some complex systems. in this paper, design of a new artificial molecular nanohinge is discussed based on nitrogen inversion in which reciprocating motion of substituent in effect of inversion phenomenon, led to an open–close moti...

We studied the configuration and expression of the gene encoding the beta chain of the T cell receptor (TCR beta) in cell lines and primary tumor cells infected by the human T cell leukemia/lymphoma (lymphotrophic) virus type I (HTLV-I). Most of the cell lines and all the primary tumor cells showed rearrangement of the TCR beta gene, and in each case the rearrangement was distinct. The majority...

Pure sulfide CIGS solar cells are interesting candidates for standalone or top in a tandem configuration. To understand the limits and improve power conversion efficiency of these devices, comprehensive approach aimed at composition, interface, process engineering should be employed. Here, latter was explored. Using two-step fabrication technique one-variable-at-a-time methodology, we found fou...

A fully integrated solar-driven water-splitting system comprised of WO3 /FTO/p(+) n Si as the photoanode, Pt/TiO2 /Ti/n(+) p Si as the photocathode, and Nafion as the membrane separator, was simulated, assembled, operated in 1.0 M HClO4 , and evaluated for performance and safety characteristics under dual side illumination. A multi-physics model that accounted for the performance of the photoab...

Analysis of penetration in pre-drilled and damaged concrete targets is the main part of anti-structure tandem warhead researches. In this paper the penetration process of the KE projectiles is investigated in pre-drilled and damaged concrete targets by analytical and numerical method. In this research, it has been tried to modify the teland model for achieving an accurate and efficient analytic...
