Based on the fault activity, geochemical data and predecessor research results on tectonic subsidence and source rock of Bohai Sea Area, this paper took Bohai Sea Area as an example to compare its structural activity factors with its source rock indexes, and then to explore fault activity’s controlling effect on source rock. And the results shows: source rock thickness is mainly controlled by fault throw of boundary fault, but it is also be influenced by others factors in different stages; Fault activity rate, climatic conditions etc. factors are all key factors influencing organic matter percentage in source rock. And the key factors may change in different stages; Present organic matter maturities in different source rock are controlled by their present tectonic subsidence. And the bigger the tectonic subsidence, the higher the maturity; Source rock qualities on different structural belts are influenced by their distances away from the boundary fault, and the closer, the better. But quality on central uplift belt is worse than that on sub-sag belt flank.

Published: September 2014

We present a novel framework for multiple pedestrian tracking using overlapping cameras in which the problems of object detection and data association are solved alternately. In each round of our algorithm, the people are detected by inference on a factor graph model at each time slice. The outputs of the inference, namely the probabilistic occupancy maps, are used to define a cost network model. Data association is achieved by solving a min-cost flow problem on the resulting network model. The outputs of the data association, namely the ground occupancy maps, are used to control the size of factors in graph model in the next round. By alternating between object detection and data association, a desirable compromise between complexity and accuracy is obtained. Our experiments involve challenging, notably distinct datasets and demonstrate that our method is competitive compared with other state-of-art approaches.

Several stress relaxation and creep tests of high temperature material are performed. According to the characteristics of stress relaxations and the superposition equation of diffusion and Maxwell equations of two stages, equivalent relaxation time and equivalent relaxation rate are proposed. Considering equivalent relaxation rate as the creep rate under constant stress, the relaxation-creep conversion model is built up and presented. Then the steady-state creep curve and creep rate are calculated. The results show that the numerical results are in good agreement with the experimental data. It indicates that equivalent relaxation rate can be employed for the analysis of steady-state creep rate. The conversion model and method can be used to design the creep strength and predict the life of the component at high temperature.

Indoor node positioning is a key technology in wireless sensor network but the general indoor nodes positioning algorithm is difficult to meet the precision positioning requirements due to the indoor complex environment such as multilateral positioning algorithm based on RSSI ranging. The weighted multilateral positioning algorithm is proposed based on time reversal ranging to solve the problem. We simulate within 50m*50m area, the experimental results show that the ranging error is less than 1%. The maximum positioning error is less than 0.6m. Compared with general positioning algorithm, it can improve the positioning accuracy greatly in complex environments and has general applicability.

Published: September 2014

The combination problem of complex event model is an important problem in complex event study. Aiming to solve the problem of no well reflecting the spatial-temporal characteristic in current comeplex even models, which are combined by atomic events based on time or space or time and space, a multi-tuple combination method of complex event model based on object, time, space, events and properties is proposed in this paper based on the analysis in existing complex event model.The basic idea of the method is to make use of intrinsic relation existing in multi tuple of event model to combine and express complex event. At a result, our supposed model not only can more comprehensively reflect the spatial-temporal characteristic of event, but also can reflect some dynamic change conditions occurred in the event. Smart home temperature and humidity detection as a case and experimental simulation are used to illustrate and prove the correctness and feasibility of the proposed complex event method based on multiple tuple.
