چکیده در این مقاله، روش حجم محدود-بولتزمن شبکه­ای برای جریان و انتقال حرارت در سیال تراکم ناپذیر توسعه داده شده است. برای حل میدان دما از تابع توزیع دوگانه بولتزمن استفاده شده است. دو ضریب تصحیح مرتبه دو برای محاسبه شار بر اساس فشار و دما در مرز سلول ­ ها در روش بولتزمن شبکه­ای و تلفیق آن با روش حجم محدود ارائه گردیده که به صورت قابل توجهی باعث افزایش سرعت همگرایی و کاهش تعداد تکرار حل عددی شده...

Locally and functionally distributed applications realized on different system architectures demand a universal, portable and intuitive software utility for interprocess communication. Remote Procedure Calling (RPC) fulfills these requirements but suffers unnecessarily strict synchronization and the danger of deadlocks with complex client/server relations. Using message passing to avoid the inh...

We investigated the protective effects of remote postconditioning (RPC) in the lungs of rats with deep hypothermia ischemia/reperfusion (I/R) injury and the role of nuclear factor E2-related factor 2 (Nrf2) signaling in this process. Forty-nine rats were randomly divided into a sham control group, deep hypothermia I/R group, RPC group, I/R+all-trans retinoic acid (ATRA) group, I/R+RPC+ATRA grou...

Background and Purpose—Nuclear erythroid 2 related factor 2 (Nrf2) is an astrocyteenriched transcription factor that has previously been shown to upregulate cellular antioxidant systems in response to ischemia. While resveratrol preconditioning (RPC) has emerged as a potential neuroprotective therapy, the involvement of Nrf2 in RPC-induced neuroprotection and mitochondrial reactive oxygen speci...

رادار هواشناسی برای برآورد بارش از رابطه بازتابش- بارندگی Z=aRbبا ضرایب a,bبهره می‌برد که این ضرایب از بارشی به بارش دیگر متفاوت هستند. این مقادیر در رادار تهران 200 a= و 6/1 b=در نظر گرفته می‌شوند که مناسب بارش‌های ملایم است. این امر موجب بروز خطا در برآورد بارش با رادار در بارندگی‌های گوناگون خواهد شد. هدف از این تحقیق، ارزیابی(تصحیح) برآوردهای رادار هواشناسی تهران از میزان بارش است. ازاین‌ر...

Previous research (Galyean et al., 1997) indicated that daily gain and feed efficiency were improved when finishing beef steers were fed graded levels of ruminally protected choline (RPC; .25, .5, and 1% of dietary DM). Responses were cubic (P < .10) in nature, with an 11% increase in daily gain and a 6.8% improvement in feed efficiency for .25% RPC vs the control diet, but no effect on gain or...

This paper addresses the problem of building reliable computing programs over remote procedure call (RPC) systems by using replication and transaction techniques. We rst establish the computational model: the RPC transactions. Based on this RPC transaction model, we present the design of our system for managing RPC transactions in the replicated-server environment. Finally we present some resul...

The rational polynomial coefficients (RPC) model is a generalized sensor model that is used as an alternative solution for the physical sensor model for IKONOS of the Space Imaging. As the number of sensors increases along with greater complexity, and the standard sensor model is needed, the applicability of the RPC model is increasing. The RPC model has the advantages in being able to substitu...

The performance of reactive powder concrete (RPC) is much higher than that ordinary concrete, and the engineering application gradually increasing. bond failure process slip between RPC reinforcement will show new characteristics. It necessary to study behavior steel bar. direct drawing test was carried out on 36 bonding specimens in order bar concrete. research shows cohesive force consists th...

fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
