Distributed simulation is an approach to building large-scale simulation models from a set of independent simulator nodes communicating via a network. The U. S. Army uses distributed simulation systems for both training and analysis. Those systems include both crewed simulators and computer generated forces (CGF) systems; the latter use software, rather than human crews, to generate the behavio...

This paper describes a software tool, LAPSE (Large Application Parallel Simulation Environment), for the simulation of large-scale programs written for the In-tel Paragon, executed on smaller-scale machines. Two timing simulators are themselves parallelized; this paper describes the conservative synchronization algorithm we have developed to synchronize the simulation. We present performance da...

The need has become apparent for real time training and simulation tools. Such tools allow for realistic network planning and training of command personnel on real Command and Control Information Systems (C2IS). Real C2IS hardware and software are connected within the simulation loop, where a tactical radio communication infrastructure is modeled on a virtual terrain. Operators of C2IS systems ...

the overall aim of this study is to calculate some water properties in the single wall carbon naotubes (swcnt) and compare them to the bulk water properties to investigate the deviation of water properties inside the swcnt from those in the bulk. here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (md) ...

one of the main architectural characteristics in the central area of iran is the relation between life and climatic conditions; e.g., the four-seasonal house which is a typical kind of the central-yard house. as the climate of isfahan is more pleasant than other desert regions in the central part of iran, wind towers are replaced with skylights to ventilate the pool area of hoze-khane. so far, ...

In a closed die forging process, it is impossible to form complex shapes in one stage, and thus it becomes necessary to use preform dies. In the present study, Backward Deformation Method and FE simulation via ABAQUS software has been used in order to design preform die of the H-shaped parts. In the Backward Deformation Method, the final shape of the part is considered as a starting point and u...

Genesis proposes a novel approach to scalability and efficiency of parallel network monitoring, modeling and simulation for network management and intrusion detection. The basis of our approach is network decomposition that creates separate network domains. Each domain is independently monitored, modeled and simulated by separate software components. Domain monitoring involves a repository of d...
