As the demand for high-performance computing (HPC) resources has increased in field of computational science, an inevitable consideration is service availability large cluster systems such as supercomputers. In particular, factor that most affects supercomputing services job scheduler utilized allocating resources. Consequent to submitting user data through analysis, 25.6% jobs failed because p...

In this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of Exhaust Gas Recirculation (EGR) temperature on destruction of the fuel’s availability due to combustion processes in IDI diesel engine cylinder. To serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

background: in the recent years nanostructured materials have been the focus of researches due to their wide-spread possibilities to provide new shapes and structures for some materials. microemulsions can provide uniform nano-sized droplets for templating. microemulsions are isotropic, thermodynamically-stable systems of oil, water and surfactant with a 20-200 nm droplet size. they can be prep...

exergy analysis of a system is a method for recognizing the value and type of system availability against surrounding environment. it also helps to find how macroscopic properties of the system change during a process. this analysis is based on first and second laws of thermodynamics. by exergy analysis proportion of each process in the internal availability transmission and the places of usefu...

to discover the current situation and characteristics of web citations accessibility, the present study examined the accessibility of 4,253 web citations in six key iranian lis journals published from 2006 to 2010. the proportion percentage of web citations increased from 11% in 2006 to 30% in 2010. the most widely cited top level domains in urls include the .edu and .org with respectively 37% ...

Vision-based traffic flow analysis is getting more attention due to its non-intrusive nature. However, real-time video processing techniques are CPUintensive so accuracy of extracted traffic flow data from such techniques may be sacrificed in practice. Moreover, the traffic measurements extracted from cameras have hardly been validated with real dataset due to the limited availability of real w...

background according to world health organization (who) estimation, more than half of all pharmaceutical products are inappropriately prescribed, distributed, and sold and more than half of all patients use the medicines prescribed for them incorrectly. as more than 40% of therapeutic costs are pharmaceutical costs, this implies a significant waste of health resources in the world. objectives t...

The IPsec protocol suite is widely used for business-critical network traffic. In order to make IPsec deployments highly available, more scalable, and failure-resistant, they are often implemented as IPsec High Availability (HA) clusters. However, there are many issues in IPsec HA clustering, and in particular in Internet Key Exchange Protocol version 2 (IKEv2) clustering. An earlier document, ...
