In the context of an era filled with frequent occurrence of emergencies, it is urgent to carry out effective treatment. The existing studies focus their research on general rule of emergency evolution, ignoring the consideration of concrete composition of scenario, while the formulation of contingency plan based on the real evolution process of the emergency is rare. In this paper, the basic mo...

this study investigates the effects of two policies of reducing profit rate and increasing supply of credits on the growth of production in the economic sectors in iran. to achieve the goal, the orani-g computable general equilibrium model was modified tothe present situation of iranian economy. the model was also extended to accommodate the financial sector of the economy. to use the cge model...

Employment of the multiple-antenna transmitters/receivers in communication systems is known as a promising solution to provide high-data-rate wireless links. In the multiuser environments, the problems of signaling and fairness for multi-antenna systems have emerged as challenging problems. This dissertation deals with these problems in several multi-antenna multi-user scenarios. In part one, a...

This paper summarises some of the main modelling and interface developments made recently in the AIMSUN microscopic traffic simulator to provide a better response to the requirements for the assessment of ITS systems, advanced transport analysis and ATMS. The description addresses two main areas: improvements on the dynamic assignment capabilities, and the embedding of the simulator in the AIMS...

With the exponential growth in the world population and the constant increase in human mobility, the danger of outbreaks of epidemics is raising. Especially in high density urban areas such as public transport and transfer points, where people come in close proximity of each other, we observe a dramatic increase in the transmission of airborne viruses and related pathogens. It is essential to h...

Network security simulator is required for the study on the cyber intrusion and defense as cyber terrors have been increasingly popular. Until now, network security simulation aims at estimation of a small-size network or performance analysis of information protection systems. However, a systematic way to develop network security simulation is needed. In this paper, an ordered UML-based scenari...

Today, one of the new technologies in the modern era is Vehicular Ad-hoc Network which has takenenormous attention in the recent years. Because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called V2V orvehicle to vehicle communication and vehicle to roadside infrastructure, called V2I. Designin...

Biases in people’s judgments of time saved by increasing the speed of an activity have been studied mainly with hypothetical scenarios (Svenson, 2008). The present study asked whether the classic time-saving bias persists as a perceptual bias when we control the speed of an activity and assess the perceived time elapsed at different speeds. Specifically, we investigated the time-saving bias in ...

This paper presents MoSS-CC (Model-based Simulation System for Cost Calculation in wastewater treatment plants), a software tool to optimise wastewater treatment plant design and operation by means of simulation and cost analysis. The scenario analysis procedure is encoded in the software as a VPL (Virtual Product Lifecycle). Roughly, the scenario consists of two phases: the design phase and th...

Although simulations can be useful tools to train dynamic decision making (DDM) skills, studies show that mere practice with simulated environments leads to limited improvements in performance. Simulated environments often show little or no transparency about the underlying structure. Making information about the system and the consequences of decisions available to users has been found to enha...
