The underground coal mine is dangerous environment with gas1. In long term operation, the insulation resistance of cable decreases, and then leads to leakage. This can result in a threat to human and production safety. The leakage fault signal is weak, and the protection methods have no selectivity. The improvement of the protection method for additional DC source is proposed in this paper. The leakage...
As autonomous or semi-autonomous vehicles are deployed on the roads, they will have to eventually start communicating with each other in order to achieve increased efficiency and safety. Current approaches in the control of collaborative vehicles primarily consider homogeneous simplified vehicle dynamics and usually ignore any communication issues. This raises an important question of how systems...
In regarding to problems existing in the EPC (Electronic Product Code) coding structure model used in food safety traceability, combined with features of food safety traceability, based on host-guest thought improves the design, this paper establishes a traceable safety information coding for beef cattle based on EPC. The coding systematically solves the coding problems of key information in the procedures...
In this paper, a model predictive control approach is proposed for a vehicle convoy traveling on homogeneous highway. Specifically, the lane change behavior of a cut-in vehicle in front of the vehicle convoy is estimated and predicted for the predictive control of the leading vehicle in the convoy. In order to capture state differences of the preceding vehicle in different lane change manners, a cost...
Combination of mobile Agent, Aglet platform and the Java language, this paper presents a security framework of e-commerce based on mobile agents and its implementation. In electronic shopping process, for example, the security issues of a mobile agent encountered in the system was detailed analysis when it migrated, registration, licensing and information exchange, and so on. The security framework...
With the demonstration application and commercialization of electric vehicles (EVs), the collision safety of EVs increasingly becomes the concern of the community. The power source of EVs is battery pack which consists of decades and even hundreds of batteries through serial connection or parallel connection, so the collision safety of EVs is different from the one of traditional vehicles. This paper...
According to industry experience, expertise and indepth research, a type of evaluation index system for undermine production of colliery safety is established. Fuzzy Hierarchy evaluation method is applied to determine the weights and scores of evaluation indexes and the grade of undermine production of colliery safety based on a large amount of statistical data of a stateowned colliery, and then suggestions...
To design and develop anticipatory reasoning-reacting systems with three-dimensional moving objects, it is indispensable to decide the fundamental logic basis to underlie anticipatory reasoning about three-dimensional moving objects. This paper investigates the fundamental logic basis for anticipatory reasoning-reacting systems with three-dimensional moving objects. The paper presents some basic requirements...
System reliability models play an important role in the reliability engineering. In order to meet the application, so far there are more than one hundred models. With the development of modern complex networks, reliability is an important criterion due the fact that failure of these networks affects its users adversely The directed tree network system is one of many network systems which are used...
Steam generator (SG) is one of the key important equipments to safety of nuclear power plant (NPP), its reliability is the one vital weakness of nuclear steam supply system (NSSS), so it is necessary for ageing management (AM) to increase its reliability for safety operation. However the SG AM data has not always been readily available, thus the Ageing Management Database of the Steam Generator of...
In this paper, the cost - quality -time - security model is lead into the projects innovatively; we describe the basic principle of the particle swarm optimization method, and introduce the integer programming as well as the structure of multi-attribute utility function. The discussion on the cost optimization in the construction phase of a substation have confirmed that the PSO method can determine...
Tobacco distribution has the main features of fast-moving, high value, uniform dimension which requires high picking efficiency, accuracy and low labor intensity. In this case, traditional manual picking needs to be replaced by proper automated picking significantly. Complex Automated Picking System (CAPS) is a kind of automated order picking system, composed of the Horizontal Dispenser (HD) and A-frame...
