This paper describes attribute extraction, attribute classification and data cleaning process in tourism emergency, builds a widely applicable decision table, and uses the attribute reduction algorithm based on the importance of Pawlak property. The results proves that the decision table after reduction is more beneficial to obtain useful decision rules, on the premise of maintaining constant dependence...
The rules of traffic accidents and their hazards in China are studied by virtue of MATLAB and the method of fuzzy mathematics. First, the general trend of linear increase and fluctuant character of the traffic accidents are found by observing the scatter graph of statistical data of traffic accidents in China, which represent a complex nonlinear combinatorial feature. Second, these data are processed...
This paper introduces BlastSim - physics based stationary multi-agent simulation of blast waves and its impact on human body. The agents are constrained by physical characteristics and mechanics of blast wave. The simulation is capable of assessing the impact of crowd formation patterns on the magnitude of injury and number of casualties during a suicide bombing attack. It also examines variables...
Suicidal attempts have a very significant effect on the society, and they also reflect on the efforts of the supporting health care and counseling facilities and the therapist involved. The impact of suicide is further magnified by the needs of persons who attempt suicide multiple times, requiring emergency health care and rehabilitation. Preventing such activities becomes a major task for the support...
According to the characteristics of atmospheric pollutants diffusion, some mathematical models were developed to evaluate the risk and consequence of chemical pollutants diffused into atmosphere. Introducing the GIS (geographic information system), the models were simulated and realized a real-time evaluation for monitoring the concentration of chemical pollutants dynamic diffusion process. Integrating...
The adjustment of county's energy strategy, environment protect requirement and the continuous progress of the automobile technology, more and more automobiles were designed on the CNG as their fuel and corresponding CNG stations were increasing at the same time. But the consequential accident such as the leakage of the gas and the fire disaster made the security of the CNG station became a serious...
Traumatic brain injury (TBI) is caused by in response to mechanical loading of the head. An extended biological cascade is initiated by the deformation and results in delayed cell death and dysfunction. Using an in vitro model of TBI based on organotypic brain slice cultures, we have quantitatively studied the relationship between tissue deformation and outcome. In the current study, we asked the...
This paper presents a Monte-Carlo simulation tool based on stationary multi-agent system. The agents are constrained by physical characteristics and mechanics of blast waves. The proposed tool examines the impact of blast waves in an event of suicide bombing on human body. The tool is capable of assessing the impact of crowd formation patterns and their densities on the magnitude of injury and number...
This paper presents the science of suicide bombing under the framework of agent based simulation. It also explains the physics, explosive models, mathematics and the assumptions we need to create such a simulation. The work also describes human shields available in the crowd with partial and full coverage in both two dimensional and three dimensional environments. A virtual simulation tool has been...
This work is set to implement, test, analyze and measure agentspsila behavior and its consequences under extreme conditions like suicide bombing. The goals are to determine optimal crowd formations and architectural and geometrical recommendations which (when followed) will reduce the number of deaths and injuries in the crowd. Results indicate that the worst crowd formation is street, with 44% crowd...
Suicide bombing has become one of the most lethal and favorite modus-operandi of terrorist organizations around the world. While various attempts have been made to assess the impact of crowd density on suicide bomber effectiveness, the specifics of the actual crowd formation and orientation of the bomber with respect to the crowd has not been examined. A virtual simulation tool has been developed...
Critical national infrastructures for power, emergency services, finance, and other basic industries rely heavily on information and telecommunications networks (voice, data, Internet) to provide services and conduct business. While todaypsilas legacy networks tend to be highly reliable, tomorrowpsilas converged networks may be less reliable and outages can have cascading effects to other infrastructures...
Some of the elements of the criminal justice system are expressed in mathematical terms. The function of the criminal justice system is postulated to be the minimization of all the losses to society resulting from crime. Losses considered include the direct and indirect loss due to a crime, the loss to the convicted criminal due to the punishment he receives, and the net cost of imposing the punishment...
