The gas producivity is infuluenced by many factors. In the routine calculation of gas productivity, many factors were negelected for convenience such as the non-Darcy flow, the changes of gas PVT parameters and the deformation of rock media. In order to analysis the effect of these factors on gas productivity, the mathematical model of high speed non-Darcy unstable flow in deformed media gas reservoir, which takes the changes of PVT of real gas with pressure into consideration, has been made in this paper. Numerical difference technology is used to find solution to the mathematical model,in which there is a well in the center of the round closed layer and the well bottom hole pressure is kept as constant in the production. And the effect of the factors on the gas productivity is analyzed. The results show that the influences of porosity changes caused by media deformation to productivity can be neglected, the changes of permeability can lead to the decreasing of productivity in the early period. And the productivity under the conditions of the high-speed non-Darcy flow and the changes of gas PVT is higher than the one when the gas flow is linear and PVT of gas is constant. These research results are meaningful to predict the gas productivity accurately.

with the development of bioinformatics, gene regulatory network research has gained growing more attention. The process of transcription regulation research has played a crucial role in the biomedical research. In a recent research work, the dynamic Bayesian network has become a powerful gene regulatory network modeling tool, which can show the power of the description of the relationship between complex gene regulations. However, because the vast majority of existing works simultaneously use all of the observational data on the reconstruction of the network structure and parameters optimization, so micro-array expression data in the timing characteristics have not been fully tapped. To solve the above problem, in this paper, the particle filter method is introduced into the framework of dynamic Bayesian networks algorithm, learning gene regulatory networks from the micro array expression data in sequential. By the test on brewer's yeast cell cycle microarray expression data, the algorithm is proven to be successful in capturing the dynamic characteristics of expression data. Experimental results show that compared some other works, the algorithm has higher accuracy, and can be more accurately expressed gene regulatory network structure.

A robust and real-time facial detector has been designed using multi-classifier combination method. The new detector composes of three classifiers: Skin color detector, AdaBoost detector based on haar-like features, and eye-mouth detector, a semi-serial architecture is designed to combine the three detectors, which set up the division and cooperation system and draw on each other's merits to implement the quick and efficient facial detection. An illumination independent skin color detector has been designed. Retinex algorithm based on the advanced adaptive smoothing filter is exploited to remove illuminant in color images and then skin color pixels are classified through there color information. This method increase efficiency and ability of skin color detection in images contaminated by illuminant. Besides this, the advanced adaptive smoothing algorithm adopts adaptive windows to replace the iteration, which guarantees real-time performance of skin color detector. Based on the acquirement and conditions of the new facial detector, a simple efficient eye-mouth classifier has been designed to reduce miss detection caused by rotary faces. The detector chooses color feature of eyes and mouth and geometric feature between eyes and mouth. Experimental result proves that the new face detector implements real-time face detection and improves detection robustness.

Timely and specific feedback enhances performance. Specific feedback that is provided throughout the learning task affects learner self-efficacy. In this paper, we introduce experiential learning; then we study Feedback in Experiential Learning; finally, we introduce self-efficacy.
