In recent years energy shortage and environmental impacts due to consuming fossil fuels have led to developing renewable energy sources systems. Since these sources are not reliable and are usually time dependent, an energy storing system like hydrogen production is required. In this regard, PEM electrolyzer can be efficiently used to decompose liquid water into hydrogen and oxygen. Because of ...

Nowadays, 3D mesh animations have been increasingly used in various applications, e.g., in digital entertainment and physically-based simulation. In many applications, it is possible that a surface animation undergoes some lossy operations which can impair its perceptual quality. Since the end users of mesh animations are often human beings, the perceptual quality assessment of 3D dynamic meshe...

Explicit time-stepping methods are commonly used to solve transient, timedependent problems. For problems involving small-scale features, adaptive unstructured mesh refinement can be effective. Unfortunately, using such dynamic strategies on parallel computers can result in difficult load balancing issues because of the relatively high cost of the mesh partitioning to the time-step computation....

We adopt parallel computing and adaptive mesh refinement in a class of iterative inverse solution strategies for tomographic surveys. Due to the algorithmic structure of these inverse solvers, a combination of data parallelism and task parallelism is best suited. Targeting clusters of multicore processor chips, it also justifies to use a mixture of message passing and threads. Moreover, adaptiv...

We present a dynamic and self-organized flow monitoring framework in Wireless Mesh Networks. An algorithmic mechanism that allows for an autonomic organization of the probes plane is investigated, with the goal of monitoring all the flows in the backbone of the mesh network accurately and robustly, while minimizing the overhead introduced by the monitoring architecture. The architecture of the ...

Problem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh network with the mesh routers. Routi...

We describe a software library for dynamic load balancing of finite element codes. The application code has to provide the current distributed mesh and information on the calculation and communication requirements, and receives from the library all necessary information to re-allocate the application data. The library computes a new partitioning, either via direct mesh migration or via parallel...

−Wireless Mesh Networks (WMN’s) are achieving swiftly developing focus in current years, and are commonly recognized as an advanced option for nest era wireless networks. Contrasted with regular wireless and mobile networks, eg. Wi-Fi based wireless networks and mobile IP networks, WMN’s have the advantages of low price, easy implementation, self organization and self healing, and being compati...

we report the cases of two patients diagnosed with morgagni hernia who presented with nonspecific abdominal symptoms. both underwent laparo­scopic surgery that used a dual-sided mesh, polyvinylidene fluoride (pvdf; dynamesh ipom®). the procedures were successful and both patients were discharged with no complications. there was no recurrence in 18 months of follow up. herein is the report of th...

aims: it is very important to detect the coagulase-negative staphylococci, which produce the hospital infections. being one of the most expensive and time-consuming stages before the polymerase chain reaction (pcr), dna extraction is one of the primary stages of pcr. then, it should be noticed that the elimination of the stage might save time and costs. the aim of this study was to compare two ...
