nowadays energy has significant role in socio economic development of counties; any decision on energy sector may affect the broad area in societies. system approach in energy modeling as an efficient method is known by many researchers in management and planning in a country particularly in energy sector. also system dynamics is one of the efficient methods, for reason unique ability at solvin...

This paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (ESPAR). The proposed method is capable of providing better capacity compared to the conventional ESPAR. The termination of each antenna element in this structure comprises a PIN diode in addition to a varactor. Using PIN diode besides the varactor provides more degrees of freed...

Simulation is the research tool of choice for a majority of the mobile ad hoc network (MANET) community. However, while the use of simulation has increased, the credibility of the simulation results has decreased. To determine the state of MANET simulation studies, we surveyed the 2000-2004 proceedings of the ACM International Symposium on Mobile Ad Hoc Networking and Computing (MobiHoc). From ...

Problem statement: Mobile Ad hoc Network (MANET), a type of network with special characteristics, needs a special mechanism to bear with its ad hoc behavior. Approach: The important issue in MANET is routing protocol. Routing protocol is a standard used to determine the route path taken during the transmission of data. Results: In this study we focused on the Ad hoc On demand Distance Vector (A...

Selecting appropriate technology strategy is crucial to those designing ICT-based offering for specific geographical market. The antecedents of adopting particular technology can be used to identify opportunities and barriers of entry, but further information is needed for technology management on how adoption would take place. In this paper, it is argued that deploying a scenario method facili...

Agent based modeling and simulation consider the behavior of agents acting in a system. The agents' interactions result in changing the agent’s behavior, the whole agent based system, and its environment. In this study, the manufacturing, sale, and receiving orders behaviors pertinent to manufacturing and sale agents acting across a pharmaceutical supply chain of an Iranian manufacturing medici...

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...

The last decade has witnessed an explosion of the interest in technologies of large simulation with the rapid growth of both the complexity and the scale of problem domains. Modelling & simulation of crowd is a typical paradigm, especially when dealing with large crowd. On top of a hierarchical Grid simulation infrastructure, a simulation of evacuating tens of thousands of pedestrians in an urb...

An efficient simulation execution engine is crucial for agentbased traffic simulation. Depending on the size of the simulation scenario the execution engine would have to update several thousand agents during a single time step. This update may also include route calculations which are computationally expensive. The ability to dynamically re-calculate the route of agents is a feature often not ...
