Simulation on the shock attenuation behavior of coupled RHA and sandwich composite panel under blast loading

This paper presents the shock attenuation behavior of engineering materials namely Rolled Homogenous Armor (RHA) and sandwich composite when subject to blast loadings. Blast loading on sandwich composite structure and monolithic material are investigated using LSDYNA 3D with Arbitrary LagrangianEulerian (ALE) method. Dynamic response in terms of shock was analyzed in order to understand the shock attenuation of monolithic structure and sandwich structures. Based from the results, coupled RHA and sandwich composite structure configuration exhibit highest  attenuation capability of 61.3% respectively. The study can be used as reference tool for the application related to automotive, naval and aeronautical structures, oil and gas industry.Keywords: shock attenuation; composite; survivability; honeycomb

The study of technological prevention method of road accident related to driver and vehicle

Considering the increasing of the number cars on the roads, the rate of road accident has also increased with many people died or sustained serious injuries in a road  accident. Increasing the phenomenon of road accident frequency, a study on the factors that may be associated with the occurrence of the accident was conducted. This paper also discussed about road accident prevention method based on the factors studied. The study of this paper can provide forceful data analysis support for the road traffic safety related research. Keywords: road accident; accident prevention; road safety

Intelligent agent simulator in massive crowd

Crowd simulations have many benefits over real-life research such as in computer games, architecture and entertainment. One of the key elements in this study is to include elements of decision-making into the crowd. The aim of this simulator is to simulate the features of an intelligent agent to escape from crowded environments especially in one-way corridor, two-way corridor and four-way intersection. The addition of the graphical user interface enables intuitive and fast handling in all settings and features of the Intelligent Agent Simulator and allows convenient research in the field of intelligent behaviour in massive crowd. This paper describes the development of a simulator by using the Open Graphics Library (OpenGL), starting from the production of training data, the simulation process, until the simulation results. The Social Force Model (SFM) is used to generate the motion of agents and the Support Vector Machine (SVM) is used to predict the next step for intelligent agent
