    In order to evaluate the stability of the process of aluminum alloy pulsed Metal Inert Gas(MIG) Arc welding, an approximate entropy analysis has been done on voltage signal in the process of aluminum alloy pulsed MIG welding. The calculation and comparison of the approximate entropy on voltage signal under different welding parameters, such as welding speeds, wire feed speeds, duty cycle and so on, shows that the approximate entropy of voltage can reflect the stability of the process of aluminum alloy pulsed MIG welding. The results show that the smaller the average value of approximate entropy, the more stable the welding process will be. Otherwise, the welding process is unstable while the average value is bigger.

    In this paper, we propose a new protein secondary structure prediction method based on kernel minimum square error (KMSE). KMSE is a supervised pattern classification method, which has been successfully applied to a wide range of pattern recognition problems. The naive KMSE focuses on two-class problem, so it can not be directly applied for protein secondary structure prediction. We design a multi-class classifier based on KMSE for protein secondary structure prediction. The results of our experiments carried out on the rs126 dataset show that the performance of our method is better than that of PCA and LDA. Our method achieves a very high degree of prediction accuracy with simple computation, and we believe it is an effective method for the prediction of the secondary structure of protein.

    In order to improve the accuracy of the satellite orbit prediction, a Doppler/Celestial integrated orbit prediction method based on two-stage filter is proposed. Celestial prediction is a mature and stable navigation for satellite. But the position determination performance is not satisfied due to the low accuracy of horizon sensor. The Doppler prediction utilizes the Doppler radial velocity relative to the Sun as measurement information. However, this method can not obtain all state estimations. For two methods are complementary to each other, the two-stage filter is used here for fusing the prediction data from the Doppler prediction and CNS. Compared to the traditional celestial prediction method, the integrated prediction method can provide better prediction performance. The simulation results demonstrate the feasibility and effectiveness of this integrated prediction. View full abstract»

    Seamless montage for texturing 3D models is very important in 3D video games and computer animations. The goal is to generate an arbitrarily large texture from a small sample image while both the sample texture and the result texture must be perceived by human observers to be the same and there is no obvious seam. This is slightly different from texture synthesis whose main principle is that the result texture must be non-periodical. Since there exist substantial periodical textures in real world, this paper presents a method for seamless montage without seams to form periodical textures. First we apply a quilting algorithm together with Wang Tiles to design the tile for montage, and we make comparison between them in terms of practical maneuverability. Then we employ the tile designed through Wang Tiles for seamless montage to generate a large texture with an arbitrary size. We also consider the montage of 3D surface textures under various illumination directions. View full abstract»

    Examination of the tongue condition is a standard diagnostic method in Traditional Chinese Medicine (TCM) and takes account of a wide variety of features including shape, texture, and color. The terms “warm”, “neutral”, and “cool” are used to refer to a kind of chromatics characteristic of the tongue color and are associated with various health states. In this paper, we propose a semi-supervised (cluster and label) scheme for tongue color analysis on “warm or cool”. In the training part, the proposed scheme makes use of a classical clustering algorithm, Expectation Maximization, to divide all pixels in tongue gamut into 150 clusters. Then we construct two auxiliary images for each cluster and manual labeling endows these clusters with category labels of “warm or cool”. Finally, each trained category on “warm or cool” is set up by sum some clusters approximately. In the testing part, we use a lookup table to divide all pixels in an input image into three distinct categories of “warm or cool”. In experiments conducted on a total of 392 tongue samples, our system achieved an accuracy of 91.1%. View full abstract»

    Although there are many methods or models widely applied to evaluate water resources carrying capacity, the evaluation result is qualitative not quantitative. In order to quantificationally evaluate groundwater carrying capacity in irrigation district, multi-objective evaluation model of groundwater carrying capacity was established, which includes four objectives, i.e., GDP, grain yield, population and COD emissions. The multi-objectives model can factually describe groundwater carrying capacity for social economy subsystem and ecological environment subsystem in irrigation district. The improved Particle Swarm Optimization (PSO) algorithm was built and adopted to solving the groundwater carrying capacity multi-objective model. In the improve PSO algorithm, linear inertia weight and chaos variation operator are employed to improve basic algorithm global searching capacity. The model was applied to quantificationally evaluate groundwater carrying capacity of People's Victory Canal irrigation district in current year and in 2010 level year. View full abstract»

    As the power density of modern chips increases drastically, chips are prone to overheating. Thermal hot spots increase cooling costs, negatively impact reliability and degrade performance. A valid task scheduling can reduce chip's average temperature and temperature variations. We propose a dynamic temperature-aware task scheduling policy based on sliding window model. This scheduling policy calculates the probability of task allocation for each core according to current and historical temperatures of the core, and then the one with the maximal probability is chosen to execute the ready task. If multiple cores have the same probability, the scheduler gives priority to the core that has the minimal average temperature of neighbor units. The experimental results show that this scheduling policy can reduce hot spots, decrease spatial and temporal temperature variations of all units, and thus achieve a relatively lower average temperature and more balanced temperature distribution.
