Hydrologic modeling of semi-arid watersheds is imperative for the development of appropriate water and soil conservation plans. In the current study, the efficiency of Kinematic Runoff and Erosion model-version 2 (K2) model was used to evaluate water discharge and sediment load simulation of Bar watershed, located in the north-eastern part of Iran. The K2 model relies on the kinematic wave appr...

abstract: since the field of micro electromechanical systems (mems) continues to grow, the flow in micro devices have become an area that receives a significant attention. the microscopic flows are usually characterized by the knudsen number (kn). when the characteristic size of the particle decreases down to a value comparable to the mean free path of the molecules, the continuum assumption fa...

Zeno hybrid automata are hybrid systems that can exhibit in nitely many discrete transitions in a nite time interval. Such automata arise due to modeling simplications and may deteriorate simulation e ciency and accuracy considerably. Some basic properties of Zeno hybrid automata are explored. Possible ways to extend a simulation beyond the Zeno time are suggested.

This paper describes the implementation of an OMNeT++-based HiperLAN/2 simulation model. The simulation models the HiperLAN/2 standard with a large degree of accuracy, in particular, in the DLC layer. It is designed to be extendable and flexible and incorporates HiperLAN/2 protocol extensions for multihop relaying. It is publicly available.

Simulation, in this Monte Carlo course, will mean direct simulation. That means producing random objects according to some description. This was supposed to be almost the opposite of Monte Carlo, where the main activity is finding ways to “cheat” – to find different random variables with the same expectation value. This chapter is here for three reasons. One is that the moderately complex rando...
