یکی از راهکارهای افزایش کارایی پردازنده های همه منظوره، استفاده از پردازنده ها با مجموعه دستورالعمل های قابل توسعه است. در این نوع پردازنده ها امکان اضافه کردن دستورالعمل های جدید برای پردازنده وجود دارد. مشکلی که برای توسعه برنامه بر روی این پردازنده وجود دارد، پیچیدگی فرایند طراحی در آنها است. انتخاب خودکار دستورالعمل های سفارشی و تشخیص آنها هزینه بالایی دارد. شناسایی دستوالعمل های سفارشی بر ...
In this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. The linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. To implement the method for the ...
Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...
Background and aims: Hospital personnel are exposed to various occupational hazards because of their job circumstances. The aim of this study is to investigate the ergonomic problems of hospital from the perspective of human-system interface technology and to recommend the strategies for improvement. Methods: In this qualitative study, the conceptual framework of hospital ergonomic problems ...
At present study, effects of wall thickness and porosity on the conjugate free convection heat transfer inside a square cavity have been examined. Continuity, momentum and energy equations for fluid and solid matrix phases are governing equations in present work. Mentioned equations and related boundary conditions have been transformed into their non-dimensional forms. They are solved using fin...
Soil nailing is a popular reinforcement method for stabilizing slopes, excavations, and retaining walls in many countries. The pullout capacity of the soil-nail interface is a critical parameter for the design and safety assessment of soil-nailed systems. In this paper, a three-dimensional (3D) finite element (FE) model is developed using the commercial program ABAQUS to simulate the pullout te...
Work function and surface energy per unit area were calculated in the framework of density functional theory (DFT) with Linearized A ug mented Plane Wave Plus Local Orbital method in full potential for a clean symmetric slab of silicon containing two (top and bottom) surfaces. The surfaces were theoretically modeled using supercell technique by stacking a variety of silicon layers along (111)...
Abstract Background and purpose: The purpose of this study was to analyze the user interface environment of some databases (Science Direct, Springer, Clinical Key, and Wiley online library) from the perspective of users applying Dervin's sense-making theory. Materials and methods: A cross-sectional descriptive study was conducted in 100 PhD students and research-based PhD students in Mazandar...
Background and Aim: Debonding is the most commonly encountered failure in teeth restored with fiber posts that mainly occurs at the weakest interface (dentin-cement interface). Thus, reinforcement of this interface is mandatory. The aim of this study was to evaluate the effect of different root dentin surface treatments after post space preparation on bond strength of fiber posts cemented with ...
In this research, the mechanism of joining three sheets of metals, i.e. brass-steel-brass, by cold roll welding process has been studied. For this purpose, the two surfaces of steel sheets were roughened with stainless steel wire brush by different amounts, then the brass sheets were put on both sides of the steel sheets, before they were subjected to cold roll process. During rolling, peaks of...
