Abstract: With the infrastructure construction of China, more and more tunnel projects are constructed. How to finish a tunnel project efficiently and effectively has become a challenge. The advance detection in tunnel geological disasters has a very important position. This paper mainly discussed the basic principle of advance detection and compared different methods according to the advantages and disadvantages. The author also put forward some suggestions on synthesis methods.

Abstract: This paper introduces an integral project about a set of video-based implementations of view interactive landscape, and determines the main technical difficulties in the implementation process and finds out solutions with the help of system architecture design, equipment selection, development of communication protocols, the picture of the acquisition, comparison, flexible timer application steps, particularly in images matching process it raises some unique solutions for the picture area, pixels brightness threshold setting, regional similarity threshold setting, image dithering elimination to achieve a good video stream under landscape light interaction and the project is successfully put into application.

Abstract: In this paper, the authors establish a class of relaxed parallel modulus-based matrix multisplitting iteration methods for large sparse linear complementarity problems, based on the multisplittings of the coefficient matrix. And then, they prove their convergence when the system matrices are H-matrix with positive diagonal elements. These results naturally present convergence conditions for the symmetric positive definite matrices and the M-matrices.
