In today’s competitive educational environment, the quality of undergraduate education is ever more recognised as a fundamental factor in gaining competitive advantage. The evaluation and improvement of the quality of undergraduate education in higher education is an important issue of on-going concern. The aim of this article is to focus on an automated management and evaluation system to effi...

We introduce hierarchical neighbor graphs, a new topology control mechanism for wireless sensor networks. This mechanism is a randomized one that takes a single parameter, 0 < p < 1, and uses it to build a structure that has the flavor of hierarchical clustering and is fully distributed in the sense that it requires only local knowledge at each node to be formed and repaired, and moreover requi...

one of the great challenges in the processing of materials using equal channel angular pressing (ecap) is the high forming forces required to produce large shear deformation in the material. researchers show that the friction forces between the die and the sample constitute a great part of the total forming forces. recently, ultrasonic vibrations are successfully implemented into the ecap proce...

Parallel computing performance on scalable shared-memory architectures is aaected by the structure of the interconnection networks linking processors to memory modules and on the eeciency of the memory/cache management systems. Cache Coherence Non-Uniform Memory Access (CC-NUMA) and Cache Only Memory Access (COMA) are two eeective memory systems, and the hierarchical ring structure is an eecien...

there are mainly two methods of deep drawing analysis; experimental and analytical/numerical. experimental analysis can be useful in analyzing the process to determine the process parameters that produce a defect free product, and the analytical/numerical modeling can be used to model and analyze the process through all stages of deformation. this approach is less time consuming and more econom...

Title Process analytical technology (PAT) needs and applications in the bioprocess industry Review Abstract Process analytical technologies have been applied to manufacturing processes (pulp and paper, chemical and petroleum) for decades. Recently, the US Food and Drug Administration (FDA) has, however, redefined the phrase and implemented it into an initiative focusing on improving several asp...

In many complex decision-making problems, the decision information provided by the decision makers is often imprecise or uncertain due to time limit, lack of data, or the decision makers’ limited attention and information processing capabilities. Decision-making in a fuzzy environment means a decision process in which the goals and/or the constraints, but not necessarily the system under contro...
