The probability hypothesis density (PHD) filter is a promising method for multi-target tracking problem. The Gaussian mixture PHD filter is an analytic solution to the PHD filter for linear Gaussian multi-target models. However, the PHD filter is inapplicable to the multi-target tracking scenario with unknown newborn target intensity. To overcome the problem, an adaptive Gaussian mixture probability hypothesis density algorithm for multiple target tracking is proposed, where the Dirichlet distribution with negative exponent parameters and target maximum velocity constraint-based schemes are introduced to recursively estimate the newborn target intensity at each time step. The simulation results illustrate that the proposed algorithm has better performance under the unknown newborn target intensity in the multi-target tracking systems. © 2016 Elsevier GmbH. Source

Mutation operator is an effective method to solve the premature of particle swarm optimization. According to the characteristic of population diversity, a modified particle swarm optimization based on adaptive mutation probability and hybrid mutation strategy was proposed. Aggregation degree was introduced to adjust the mutation probability of each generation, and a hybrid Gaussian and Cauchy mutation based on the global-best position and an adaptive wavelet mutation based on the worst personal-best position were carried out. The simulation of the comparisons with other particle swarm optimizations with mutation operator on matlab was proposed. The results demonstrate that the proposed algorithm can obtain higher accuracy solution and have better performance. © 2016, The Editorial Board of Journal of System Simulation. All right reserved.

Moisture content uniformity is one of critical parameters to evaluate the quality of dried products and the drying technique. The potential of the hyperspectral imaging technique for evaluating the moisture content uniformity of maize kernels during the drying process was investigated. Predicting models were established using the partial least squares regression method. Two methods, using the prediction value of moisture content to calculate the uniformity (indirect) and predicting the moisture content uniformity directly, were investigated. Better prediction results were achieved using the direct method (with correlation coefficients RP = 0.848 and root-mean-square error of prediction RMSEP = 2.73) than the indirect method (RP = 0.521 and RMSEP = 10.96). The hyperspectral imaging technique showed significant potential in evaluating moisture content uniformity of maize kernels during the drying process. © 2015 Institute of Agrophysics, Polish Academy of Sciences.

This study considers the problem of finite-time H∞ control for a class of discrete-time time-delay Markov jump linear systems governed by deterministic switches. By allowing the stochastic Lyapunov function to increase at every switching instant with a limited increase rate, new results on the stochastic finite-time boundness with given H∞ disturbance attenuation level are derived. Moreover, the coupling relationship among time-delay, average dwell time and given finite-time horizon of the underlying system is obtained through an average dwell-time constraint. Finally, one example is given to demonstrate the validity of the obtained results. © The Institution of Engineering and Technology 2014. Source

A fast tag anti-collision algorithm named Fast Query Tree (FQT) is presented. FQT is an improved technique based on query tree algorithm, the novelty of FQT is that it use a counter and a pointer in each tag for tag transmission arbitration, owing to the counter and pointer, which on the other hand remembered the reader's query history, reader just needs to transmit the last bit of the current prefix. The simulated results show that FQT can achieve a better performance than other conventional tree-based algorithms in terms of communication overhead, identification delay and speed. © 2011 IEEE.
