Abstract: During the period of the republic of China,"JueLanShe" is an emerging art community, and the original aim is through the group practice to introduce and spread western modern painting, becoming the pioneers of the new art movement in China. However, owing to the war and increased domestic environmental degradation, coupled with community art fun mix of poorly organized and community members, the group's artistic achievement is not highlighted, eventually the group gradually weakened with the influence of the four session of exhibition of fine arts and failed. This paper highlighted the introduction of the background, the process of "JueLanShe”, and the main activities and final dissolution, and evaluated its influence.

Keywords: "JueLanShe", modernism, art movement

Abstract: More and more attention goes to energy conservation in traffic system, as on one hand, it can cut down expenses, while on the other hand, it can decrease pollution discharged to the air. Two key links for energy conservation operation are optimization of timetable and optimization of running scheme in traffic system. The former adjusts running time and route between stations, while the latter determines a series of control by traction and brakeage in running. Based on analysis of kinetic model and kinematics model in running of train, the paper utilizes Matlab software to optimize optimization model of objective to optimize design of train's running scheme and decrease train's energy consumption.

Keywords: train, energy conservation, optimization, speed

Abstract: In view of the present situation of water pollution in the Yangtze River Basin, the comprehensive pollution index method is used to judge whether the water quality standard or exceed the standard. We use the size of P to evaluate the water quality of the Yangtze River comprehensively .And use the standard deviation of the proportion of each individual to seek the weight of pollution indicators, and finally analyze the water pollution situation of 17 stations. In this paper, we judge the amount of sewage by using discharge rate. By seeking the upper and lower bounds of the amount of sewage in each section of the Yangtze River, we get the section of the Yangtze River sewage ranking in the largest amount. This solution solves the trouble caused by unknown quantity (the number and the corresponding amount of sewage in a river outfall).

Keywords: Integrated pollution index model, Discharge rate, Water quality category, gray prediction

Abstract: The increasing growth of space junk in the earth orbit has caused concern form various countries’ national space agencies. Currently, there has been more than 4500 tons of space junk in the Earth's orbit. If those junks are not cleared, they will bring great threat to the security of space craft. Aiming at the lowest cost, by using space junk processors released by satellite carriers to remove space junk, we establish a satellite carrier switching orbit model based on the differential systems with Markovian Switching. More precisely, by observing whether the space junk within the each region range of satellite carrier scanning has processing value, we divide orbit switching strategy into two cases: one case is a differential system with Markovian Switching based on the probability transition matrix; the other case is the artificial switching system. To optimize the energy thrust, this paper designs the optimal index function for the optimum feedback controllers. Furthermore, we introduce some matrix   to describe some stochastic failure of thruster, and give some appropriate sufficient conditions to ensure the stochastic stability of switching orbit system. Finally, we do the cost-benefit analysis, and further prove the feasibility of our technology.

Keywords: satellite carrier; Markovian Switching; stochastic failure

Abstract: Space junk refers to what the human abandoned in the space in the space activity, namely the space trash. Therefore, how to clean up space junk, and how to reduce the hazards to the greatest extent, are two widely concerned problems by the international media. More precisely speaking, the problem is considered to be divided into the three stages of orbit determination, optimal control capture and orbit dynamic control, and all stages are modeled and simulated to validate the correctness of models. Taking space junk in low orbit as an example, this paper uses the motion law (including quality, size, location and other relevant data) of the space junk in low orbit (affected by air resistance) to establish the space junk orbit model. To minimize costs and risks, by changing the driving force, we establish the "Recycle Bin" orbit dynamic model, and give the shortest time performance index of the orbit control model. The Gauss pseudo spectral method is introduced to solve the optimal rendezvous points of the capture system, and the effectiveness of the method is verified.

School of Energy and Resource, University of Geosciences (Beijing), Beijing 100083, China

Abstract: For the solution gas drive reservoir, this article utilized multi-segment well model in Eclipse reservoir simulation software, following Cheng’s way to study the inflow performance characteristics of slanted wells with five different deviations. After synthetically considering the reservoir properties as well as the features of wellbore, different slanted well models were established. On the base of them, the factors which influenced inflow performance characteristics were analyzed. Following Vogel’s dimensionless IPR curve method, this study handled with IPR curves of all the models, while a large quantity of nonlinear regression fittings were done by origin software. Then, a new dimensionless IPR curves relationship, which took formation heterogeneity into consideration, was given. The new formula, which is better than Cheng’s, can give a more quick and convenient way to predict the inflow performance of slanted wells.

Color and Fluorescence Fundus Image Registration Method Based on Speed-up Robust Feature

Wan Zhu, Xiaonan Li, Wen Wang*

School of Electronics and Information Engineering, Tianjin Polytechnic University, Tianjin 300387, China

Abstract: Fundus image plays an important role in the diagnosis of eye diseases. In order to have a comprehensive understanding of retinal image, doctors need to take pictures from different sources of the patient's eyes. Because of the movement of the eyes of the patient, there are some differences between the corresponding physiological structures. So it is necessary to carry out registration before information fusion. In this paper, a registration method based on speed-up robust feature is proposed. Firstly, preprocessing is performed on the fundus images. Secondly, vessel segmentation and SURF feature points extraction are operated, and the descriptors are generated. Finally, the spatial transformation of the fundus fluorescein angiography image is carried out. In the test, 120 fundus images of 20 patients are tested, the results show that for different resolutions, angles, and translations, our method can achieve automatic registration, and the average matching rate reaches 93.3%, and precision reaches sub pixel level.

Keywords: color fundus image, fundus fluorescein angiography, registration, vessel segmentation, feature matching
