Subscriber records and application software programs are located within the processing elements to avoid having to send message traffic over the network requesting such information and to avoid the use of a centralized database server. In one advantageous embodiment of the invention, the processing element unit is a visitor location register.

The invention relates to a micro-nano particle reinforced aluminum-based composite material and a preparation method thereof. The aluminum-based composite material takes aluminum or an aluminum alloy as a substrate material; micron-scale silicon carbide particles and nano alumina particles are uniformly dispersed in the substrate material; and the nano alumina particles are generated by undergoing a thermit reaction on nano copper oxide particles and a substrate alloy on the surfaces of the silicon carbide particles, so that a micron silicon carbide / nano alumina reinforced aluminum-based composite material is formed. The preparation method of the aluminum-based composite material comprises the following steps of: undergoing a reaction on micron-scale silicon carbide powder and soluble copper salt in an alkaline solution; filtering, baking and grinding to obtain silicon carbide / copper oxide composite powder; and undergoing a thermit reaction on the composite powder and an aluminum melt, and casting and molding to obtain a target product. By adopting the method, composite reinforcement of the substrate is realized by particles of multiple scales and multiple types, the obtained aluminum-based composite material has the advantages of high intensity, high wear resistance and the like, the bending resistance and Brinell hardness of the aluminum-based composite material are increased by over 50 percent and 73 percent compared with those of the conventional aluminum alloy respectively, and the friction coefficient is lowered by over 25 percent.

This invention provides a method for carrying out advertisement detection to a video signal and a related system, In the video signals provided by broadcast and TV media, some broadcast segments are inserted between normal programs which makes the adjacent pictures discontinuous at the insertion is replayed after the advertisement is finished. This invention firstly detects if the picture between two adjacent frame is continuous in the video signals and scarches for frame with similar pictures frame, if so, it can evaluate frames covering advertisement between the two frame to realize the detection.

The invention discloses a velocity modeling method based on RTM imaging. The velocity modeling method includes the following steps that based on collected seismic data, a first depth-velocity model of a sedimentary strata is established with log data as constraint information; based on the first depth-velocity model, chromatography velocity modeling is performed with the log data as the constraint information so that a second depth-velocity model can be established, and RTM imaging can be performed; based on a result of RTM imaging, the second depth-velocity model is corrected with the log data as the constraint information so that a final depth-velocity model and a final RTM imaging result can be obtained. While high-precision chromatography velocity modeling is kept, the log data and other prior information are effectively added, the precision of velocity modeling is improved for complex fault blocks, and the quality of RTM imaging is improved.
