Differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. A numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. Reservoir is modeled using the Eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. Dynamic equilibr...

in today's competitive world, establishıng a proper system of evaluating firms performance is essential. the purpose of this study is to evaluate the financial performance of pharmaceutical, basic metals and automotive parts companies using a new method. the fuzzy ahp is used for weighting the performance evaluation measures and fuzzy topsis and fuzzy vikor is also used to rank the compani...

Monitoring network performance and status is a fundamental task for network operators as it directly impacts the quality of the offered services and hence user satisfaction. For this purpose a consolidated approach, which is largely adopted by network operators, is based on the so-called KPIs (key performance indicators). In this paper, we propose and discuss a set of KPIs to monitor network pe...

background: knowledge production and evaluation are two important functions of health research system (hrs). in this article, we aimed to reveal the correlation between evaluation of health research organizations and health knowledge production promotion. methods: a comprehensive evaluation system was developed to evaluate the academic performance of national medical science universities on an ...

The recent years have seen a considerable increase in the number of cluster systems. These systems provide a very good performance-cost ratio. However, in order to meet the requirements for ever-increasing computing power of present day applications, several SMP cluster systems have emerged. By deploying two or more processors per workstation can increase the performance of a cluster significan...
