This paper presents a numerical investigation of the laminar mixed convection flow of a radiating gas in an inclined lid-driven cavity. The fluid is treated as a gray, absorbing, emitting, and scattering medium. The governing differential equations including continuity, momentum and energy are solved numerically by the computational fluid dynamics techniques (CFD) to obtain the velocity and tem...

Because of the difficulty of simulating large complex systems with traditional tools, new approaches have and are being developed. One group of interrelated approaches attempts to simultaneously make simulation modeling and analysis easier while at the same time providing enough power to handle more complex problems. This group includes the following important (overlapping) approaches: integrat...

This paper addresses the problem of goal-driven simulation. Goal-driven simulation is a task frequently performed by users of simulation systems. It consists in determining, when possible, an assignment of one or several decision variable(s) in order to obtain a particular value for a specific goal variable. This task is poorly supported in simulation systems because of lack of appropriate algo...

The acceptance of the right project which leads to the realization of the set objectives is one of the most important issues in project-oriented companies. Therefore, corporate managers prefer to work on those projects which ensures the achievement of goals such as increasing financial profits or being the top brands in their rivals market. The present  research aimed at introducing  a systemat...

This paper describes an eecient execution-driven technique for the simulation of shared-memory multiprocessors driven by real programs. Our simulator ooers substantial advantages in terms of reduced time and space overheads when compared to instruction-driven or trace-driven simulation techniques, without signiicant loss of accuracy. The technique produces correctly interleaved address traces a...

Traditionally, event-driven simulations have been limited to the very restricted class of neuronal models for which the timing of future spikes can be expressed in closed form. Recently, the class of models that is amenable to event-driven simulation has been extended by the development of techniques to accurately calculate firing times for some integrate-and-fire neuron models that do not enab...

We describe how we plan to convert a traditional data collection sensor and ocean model into a DDDAS enabled system for identifying contaminants and then reacting with different models, simulations, and sensing strategies in a symbiotic manner. The sensor is just as useful in water as it would be on Mars for material identification. A successful terrestrial application of the sensor will lead t...

Abstract. This paper describes an experiment in studying coordination in intelligent agent societies in terms of state-variable models. An overview of the modeling framework is first provided. The architectural foundation for the modeling approach is then described. This description is followed by a sample application of the methodology in analyzing a coordination scenario. A simulation of the ...

We propose an event-driven algorithm for the control of simple robot assembly problems based on noncooperative game theory. We examine rigorously the simplest setting — three bodies with one degree of freedom and offer extensive simulations for the 2 DOF extension. The initial analysis and the accompanying simulations suggest that this approach may indeed, offer an attractive means of building ...

In this paper we present a tool for the simulation of fluid models of high-speed telecommunication networks. The aim of such a simulator is to evaluate measures which can not be obtained through standard tools in reasonable time or through analytical approaches. We follow an event-driven approach in which events are associated with rate changes in fluid flows. We show that, under some loose res...
