Real-Time detecting abnormal formation pressure can not only prevent the happening of drilling hazard, but also effective protect the pollution of reservoir. A detective model can be made from some drilling-logging parameters because these parameters collected by comprehensive logging instrument can indicate the abnormal pressure information existing in the formation. First, a PCA method is used to process six wells from Dongying Depression, China in order to reduce the cross-correlation among parameters and the count. Then a neural net model is trained by the result in the first step. Finally, thirty wells are detected by the model. The correspondence between real data and predicted results is about 84.6%. So this method can be used in the real case.

Coal mine underground drainage system undertakes the important task of draining all the inflow produced during the process of production in underground coalmine, hence it is important equipment in mine production. The design of monitoring and control system of underground drainage pump is thus particularly important. In this paper, according to the practical underground work situations of a mine, a set of monitoring and control system of underground drainage pump based on PLC of Siemens S7–200 series and 10-inch touch screen of Delta DOP-B series (HM1) was designed. This system adopts S7–200 series CPU224PLC and EM231A/D module as its core, collects the operation parameters of underground drainage pump and displays them, automatically controls the startup and shutdown of drainage pump, monitors the water mark of shaft sump, and gives alarms in case of too high water level. It operates reliably and has high cost performance, thus enjoying bright prospect for promotion.

By satisfactory control theory, a design approach of state feedback controllers was proposed for a class of uncertain descriptor systems, such that the closed-loop descriptor system satisfied the consistency of constraint indices of admissibility, H infinity and output-variance. First, a necessary and sufficient condition was presented for the closed-loop descriptor system with admissibility and given H infinity constraints. Then via quasi-Newton approach, the solvability of nonlinear matrix inequality was transformed into the minimization problem of maximum eigenvalue. Controller design method was provided for state feedback control with constraints of admissibility, H infinity and consistency output-variance, and a range was presented for output-variance which was consistent with the given H infinity. Finally a numerical example is given to illustrate the results obtained and the design scheme provided.

In order to improve the segmentation accuracy, reduce under-segmentation and over-segmentation, this paper proposes a new algorithm for detecting moving objects. The method is based on background subtraction algorithm and integrated with fuzzy inference for thresholding and background update. We use 7 fuzzy rules which can effectively model the membership of a pixel in a moving object during the fuzzy inference. The inference algorithm is both pixel-based and region-based. It properly segments the moving object from the stationary background. Moreover, the background model is updated by fuzzy logic with dynamic update rate over time to overcome the noise and illumination changes, which occurs frequently in complex natural environments. So the algorithm is suitable for a long run without losing accuracy. The experiment results show that our method is robust as well as fast in performance.
