In this paper, we propose a flow-level simulator called FSIM (Fluid-based SIMulator) for performance evaluation of large-scale networks, and verify its effectiveness using our FSIM implementation. The notable feature of our flow-level simulator FSIM is fast simulation execution compared with a conventional flow-level simulator. For accelerating simulation execution speed, our flow-level simulat...

AIM The aim of this study was to evaluate how simple it is to build a homemade low-cost simulator using a simple 5-step scheme. METHODS A scheme explaining how to build an endoscopic surgery simulator in 5 easy steps was presented to 26 surgeons. The simulator required a pair of scissors and easy-to-find materials. Its total cost was less than €35. The participants assessed the simulator usin...

abstract land use change, especially natural ecosystems transformation, has high effects on soil physico-chemical as well as biological characteristics and also, has effect on runoff and soil erosion. analysis of runoff and soil erosion dynamics can be useful in improvement of management proposals and quantifying runoff and soil erosion changes. so, this research was carried out to investigate ...

objectives: most studies have performed to identify the affective variables in using mobile phone by drivers based on interview and questionnaire. in this study call answering rate while driving was investigated in a sample of male postgraduate students of a university in tehran by a driving simulator. methods: six driving scenario designed differing in risk of driving. answer rate to mobile ph...
