Surface Mine System Simulation and Safety Risk Management

Modem surface mines, either mono-system or multi-systems, need a large fleet of equipment consisting of excavators, loaders, haulers and auxiliary machines. Presently, the complexity of the system, the interference between sub-systems and the lag in management skills has been a bottle neck for improving productivity of the system. Based on the fact that the traditional tools for safety analysis have been insufficient to evaluate systematically and dynamically the safety risks, this paper tries to create a virtual reality tool consisting of human, machine and mines, using Pro/E and the 3D MAX software in order to evaluate visually the operations of typical mining equipment, such as the bucket wheel excavator （BWE）, the shovel, the truck and the dragline. Within this virtual world, the behavior of the system, such as interaction, interference and potential risk can be replayed and reviewed visually. The objective of the study is to identify the critical safety issues of the system and to provide a convenient and powerful tool for safety training and safety management.

Visualization of flatness pattern recognition based on T-S cloud inference network

Flatness pattern recognition is the key of the flatness control. The accuracy of the present flatness pattern recognition is limited and the shape defects cannot be reflected intuitively. In order to improve it, a novel method via T-S cloud inference network optimized by genetic algorithm(GA) is proposed. T-S cloud inference network is constructed with T-S fuzzy neural network and the cloud model. So, the rapid of fuzzy logic and the uncertainty of cloud model for processing data are both taken into account. What's more, GA possesses good parallel design structure and global optimization characteristics. Compared with the simulation recognition results of traditional BP Algorithm, GA is more accurate and effective. Moreover, virtual reality technology is introduced into the field of shape control by Lab VIEW, MATLAB mixed programming. And virtual flatness pattern recognition interface is designed.Therefore, the data of engineering analysis and the actual model are combined with each other, and the shape defects could be seen more lively and intuitively.

Virtual reality approach for 3D large model browsing on web site

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator’s Garden. Translating building data to the Virtual Reality Modeling Language (VRML) is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-of- detail switching.

The application results show that the method is feasible and effective by simulating the whole construction process for the platform with four bucket foundations.

Solving the Perennial Problems of Inadequate Physical Laboratories in Africa Through the Use of Virtual Reality Technology and Tools

The major restriction for learning in science and engineering education in Africa is the absence of equipped laboratories. Where laboratory is available, there is the problem of obsolete and antiquated materials, which are seldom available for use. In most Universities in Africa, there is inadequate supply of laboratory space and laboratory materials. The laboratories only have the items of equipment that were provided when the universities were established, this has hampered learning. An alternative educational approach is required to address the aforementioned problems and provide a cost-effective solution for education as well as a valuable complementary or learning tool for university students. The alternative approach is the use of Virtual Reality （VR） technology to simulate virtual learning environments such as virtual reality laboratories. This is a one solution to inadequate physical laboratories in Africa.

From the Pictorial Symbols of the Theatre to the Virtual Symbolisation of the Real

In many representative, literary, cinematic, or artistic products of modern civilization, the problem of world＇s reality and the relationship of the subject with it, are seen from different viewpoints, such as the dimension of the utopian perception of a dreamlike or imaginary composition, subconscious creation, but also more complex versions such as computer mediated complete illusion, artificial intelligence, and control of the brain, intrusion, and influence exerted on the thought of the other using modern technology or any combination of all the above. It is thus understood that the issue at hand can be approached from a variety of viewpoints and aspects, such as the philosophical, psychological, psychoanalytical, technological, neurophysiologieal, sociological, literary and so on Our viewpoint is strictly limited to the theatrical dimension and our analysis will prosress based on data comprising the theatrical phenomenon, that is, the illusion, as opposed to virtual reality of modern technology.
