Aiming at the tracking failure in dynamic scene with fixed template and drift problem caused by using dynamic model in visual tracking, an improved target tracking algorithm with two-phrase is proposed. Dimension reduction on positive and negative samples is made in high dimension feature space using partial least squares (PLS), and then the appearance model of target is constructed in learned low dimension feature subspace. Target tracking is carried out within the Bayesian inference framework with two-phase: In first phase, the preliminary estimation of target location is achieved by using the principle of particle filter; in second phase, the adaptive benchmark model is adopted to determine the final target location. Experimental results demonstrate the effectiveness of the proposed algorithm. © 2017 IEEE.

Biosorption characteristics of Cr(VI) from aqueous solution by heat-treated Saccharomyces cerevisiae were investigated in a batch system. The influence of solution pH, initial Cr(VI) concentration, biomass concentration, co-existing ions, contact time and temperature on biosorption was explored. The biosorption was highly pH-dependent, and the optimum pH for biosorption was found to be 2.0. Adsorption capacity of Cr(VI) onto biomass decreased with a rise in biosorbent dosage and increased with the increasing initial Cr(VI) concentration. It was indicated that an increase in temperature would be favorable to Cr(VI) adsorption onto Saccharomyces cerevisiae in the range of 20°C–40°C. The biosorption process better followed the pseudo-second-order kinetic model, and the correlation coefficients obtained from the pseudo-second-order model were all higher than 0.99. The Langmuir and Freundlich isotherm models were applied to experimental equilibrium data. The Langmuir model better described the adsorption equilibrium than the Freundlich model. According to the Arrhenius equation, the activation energy of adsorption of chromium(VI) ions was determined as 18.37 kJ/mol. The calculated thermodynamic parameters indicated that Cr(VI) biosorption onto Saccharomyces cerevisiae was spontaneous and endothermic under studied experimental conditions. The results suggest that the biomass of Saccharomyces cerevisiae is a promising biosorbent for removal of chromium(VI) ions from the wastewater. © 2017 Desalination Publications.

In the transmission system of drive axle, the gears' transmission performance of final drive and differential is the key to transmission system. Based on Automatic Dynamic Analysis of Mechanical System (ADAMS), the virtual gear meshing prototype of final drive and differential were established. Based on the Hertz elasticity impact theory, the contact forces between gears were built. The real-time dynamic simulation of gear meshing was achieved. The gears' transmission of final drive and differential in drive axle was simulated under limit conditions by imposing different torque in driving gear of final drive and differential gears. The curves of meshing force and angular speed of differential gears and driving gears of final drive are obtained. The theoretical reference is provided to the study of the dynamic characteristics in gear transmission system.

In this paper, we investigate the multiple attribute decision making (MADM) problems for evaluating the E-commerce system security with uncertain information. Then, based on the traditional grey relational analysis (GRA) method, calculation steps for solving multiple attribute decision-making problems with completely known weight information are given. The degree of grey relation between every alternative and positive ideal solution is calculated. Then, a relative relational degree is defined to determine the ranking order of all alternatives by calculating the degree of grey relation to both the positive-ideal solution (PIS). Finally, an illustrative example is given.


Nanometer calcium titanate immobilized on Aluminum oxide (ACTO) was successfully prepared by the citrate acid sol-gel method and characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The adsorption capability of ACTO for Pb2+, Cd2+and Zn2+ from water was studied. Adsorption and elution were investigated under different conditions. The results show that nanometer calcium titanate could be immobilized on the aluminum oxide firmly, becoming a composite adsorbent. The Pb2+, Cd2+and Zn2+ were retained at pH 5-9, their adsorption capacities of ACTO were 124 mgg-1, 8.58 mgg -1 and 13.86 mgg-1, respectively. The adsorption agent can be regenerated by elution with 2 molL-1 HNO3. The adsorbent has a promising prospect in removal or enriching and separation of heavy metals in water. © (2011) Trans Tech Publications, Switzerland.

In this paper, we investigate the multiple attribute group decision making (MAGDM) problems for evaluating the security of wireless sensor network (WSN) with triangular fuzzy linguistic information. We utilize the triangular fuzzy linguistic weighted geometric (TFLWG) operator to aggregate the triangular fuzzy linguistic information corresponding to each alternative and get the overall value of the computer network systems, then rank the computer network systems and select the most desirable one(s) by using the formula of the degree of possibility for the comparison between two triangular fuzzy linguistic variables. Finally, an illustrative example for evaluating the security of wireless sensor network (WSN) is given to verify the developed approach and to demonstrate its practicality and effectiveness.

This paper addresses the observer-based, dynamic state feedback stabilization problem for networked control systems (NCSs) with limited data rates over noisy communication channels. A dynamic, finite-level logarithmic quantization method is proposed. A lower bound of data rates of noisy channels, above which there exists a quantization, coding and control scheme to stabilize the unstable plant, is derived. An illustrative example is given to demonstrate the effectiveness of the proposed method.© 2011.

Research on human recognition based on vision has got more and more attention recently, which contributes to the theoretical development of computer vision and pattern recognition, and has important meaning. This paper presents a human recognition method that based on sequence silhouette matching. First extracted the silhouette image of action sequence, then using sparse representation method extracted the feature, finally recognized the human using sparse function. Experience is done in WEIZMAN database and results show that the method has a high recognition rate.

In this paper, we investigate the multiple attribute decision making (MADM) problems for software selection with triangular intuitionistic fuzzy information.
