2CONVERGENCERATESIN THESTRONG LAWSOFASYMPTOTICALLY NEGATIVELY ASSOCIATEDRANDOM FIELDS显示文摘In this paper, a notion of negative side ρ \|mixing ( ρ\+- \|mixing) which can be regarded as asymptotic negative association is defined, and some Rosenthal type inequalities for ρ\+- \|mixing random fields are established. The complete convergence and almost sure summability on the convergence rates with respect to the strong law of large numbers are also discussed for ρ\+-\| mixing random fields. The results obtained extend those for negatively associated sequences and ρ\+*\| mixing random fields.Zhang Lixin\ Wang Xiuyun 1999Applied Mathematics(A Journal of Chinese Universities)1999,14,4:52
3A wireless solution for greenhouse monitoring and control system based on ZigBee technology显示文摘With the rapid development of wireless technologies, it is possible for Chinese greenhouses to be equipped with wireless sensor networks due to their low-cost, simplicity and mobility. In the current study, we compared the advantages of ZigBee with other two similar wireless networking protocols, Wi-Fi and Bluetooth, and proposed a wireless solution for green- house monitoring and control system based on ZigBee technology. As an explorative application of ZigBee technology in Chinese greenhouse, it may promote Chinese protected agriculture.ZHANG Qian YANG Xiang-long ZHOU Yi-ming WANG Li-ren GUO Xi-shan 2007Journal of Zhejiang University-Science A(Applied Physics & Engineering)2007,8,10:60

7Model predictive control for adaptive cruise control with multi-objectives: comfort,fuel-economy,safety and car-following显示文摘For automated vehicles,comfortable driving will improve passengers’ satisfaction.Reducing fuel consumption brings economic profits for car owners,decreases the impact on the environment and increases energy sustainability.In addition to comfort and fuel-economy,automated vehicles also have the basic requirements of safety and car-following.For this purpose,an adaptive cruise control (ACC) algorithm with multi-objectives is proposed based on a model predictive control (MPC) framework.In the proposed ACC algorithm,safety is guaranteed by constraining the inter-distance within a safe range; the requirements of comfort and car-following are considered to be the performance criteria and some optimal reference trajectories are introduced to increase fuel-economy.The performances of the proposed ACC algorithm are simulated and analyzed in five representative traffic scenarios and multiple experiments.The results show that not only are safety and car-following objectives satisfied,but also driving comfort and fuel-economy are improved significantly.Li-hua LUO Hong LIU Ping LI Hui WANG 2010Journal of Zhejiang University-Science A(Applied Physics & Engineering)2010,11,3:34

9An efficient enhanced k-means clustering algorithm显示文摘In k-means clustering, we are given a set of n data points in d-dimensional space úd and an integer k and the problem is to determine a set of k points in úd, called centers, so as to minimize the mean squared distance from each data point to its nearest center. In this paper, we present a simple and efficient clustering algorithm based on the k-means algorithm, which we call en- hanced k-means algorithm. This algorithm is easy to implement, requiring a simple data structure to keep some information in each iteration to be used in the next iteration. Our experimental results demonstrated that our scheme can improve the computational speed of the k-means algorithm by the magnitude in the total number of distance calculations and the overall time of computation.FAHIM A.M SALEM A.M TORKEY F.A RAMADAN M.A 2006Journal of Zhejiang University-Science A(Applied Physics & Engineering)2006,7,10:28
10Error estimates of H^1-Galerkin mixed finite element method for Schrdinger equation显示文摘An H1-Galerkin mixed finite element method is discussed for a class of second order Schrdinger equation. Optimal error estimates of semidiscrete schemes are derived for problems in one space dimension. At the same time, optimal error estimates are derived for fully discrete schemes. And it is showed that the H1-Galerkin mixed finite element approximations have the same rate of convergence as in the classical mixed finite element methods without requiring the LBB consistency condition.LIU Yang LI Hong WANG Jin-feng 2009Applied Mathematics(A Journal of Chinese Universities)2009,24,1:28

12Hybrid discrete particle swarm optimization algorithm for capacitated vehicle routing problem显示文摘Capacitated vehicle routing problem (CVRP) is an NP-hard problem. For large-scale problems, it is quite difficult to achieve an optimal solution with traditional optimization methods due to the high computational complexity. A new hybrid ap- proximation algorithm is developed in this work to solve the problem. In the hybrid algorithm, discrete particle swarm optimiza- tion (DPSO) combines global search and local search to search for the optimal results and simulated annealing (SA) uses certain probability to avoid being trapped in a local optimum. The computational study showed that the proposed algorithm is a feasible and effective approach for capacitated vehicle routing problem, especially for large scale problems.CHEN Ai-ling YANG Gen-ke WU Zhi-ming 2006Journal of Zhejiang University-Science A(Applied Physics & Engineering)2006,7,4:26
13Critical review in adsorption kinetic models显示文摘Adsorption is one of the most widely applied techniques for environmental remediation. Its kinetics are of great significance to evaluate the performance of a given adsorbent and gain insight into the underlying mechanisms. There are lots of references available concerning adsorption kinetics, and several mathematic models have been developed to describe adsorption reaction and diffusion processes. However, these models were frequently employed to fit the kinetic data in an unsuitable or improper manner. This is mainly because the boundary conditions of the associated models were, to a considerable extent, ignored for data modeling. Here we reviewed several widely-used adsorption kinetic models and paid more attention to their boundary conditions. We believe that the review is of certain significance and improvement for adsorption kinetic modeling.Hui QIU Lu LV Bing-cai PAN Qing-jian ZHANG Wei-ming ZHANG Quan-xing ZHANG 2009Journal of Zhejiang University-Science A(Applied Physics & Engineering)2009,10,5:26

16Personal Review:Sources of sulfide in waste streams and current biotechnologies for its removal显示文摘Sulfide-containing waste streams are generated by a number of industries. It is emitted into the environment as dis- solved sulfide (S2- and HS-) in wastewaters and as H2S in waste gases. Due to its corrosive nature, biological hydrogen sulfide removal processes are being investigated to overcome the chemical and disposal costs associated with existing chemically based removal processes. The nitrogen and sulfur metabolism interacts at various levels of the wastewater treatment process. Hence, the sulfur cycle offers possibilities to integrate nitrogen removal in the treatment process, which needs to be further optimized by appropriate design of the reactor configuration, optimization of performance parameters, retention of biomass and optimization of biomass growth. The present paper reviews the biotechnological advances to remove sulfides from various environments.MAHMOOD Qaisar ZHENG Ping CAI Jing HAYAT Yousaf HASSAN Muhammad Jaffar WU Dong-lei HU Bao-lan 2007Journal of Zhejiang University-Science A(Applied Physics & Engineering)2007,8,7:22
17Dynamic simulation and optimal control strategy for a parallel hybrid hydraulic excavator显示文摘The primary focus of this study is to investigate the control strategies of a hybrid system used in hydraulic excavators. First, the structure and evaluation target of hybrid hydraulic excavators are analyzed. Then the dynamic system model including batteries, motor and engine is built as the simulation environment to obtain control results. A so-called multi-work-point dynamic control strategy, which has both closed-loop speed PI (proportion integral) control and direct torque control, is proposed and studied in the simulation model. Simulation results indicate that the hybrid system with this strategy can meet the power demand and achieve better system stability and higher fuel efficiency.Xiao LIN Shuang-xia PAN Dong-yun WAN 2008Journal of Zhejiang University-Science A(Applied Physics & Engineering)2008,9,5:23

19Output speed and flow of double-acting double-stator multi-pumps and multi-motors显示文摘The primary focus of this study was to investigate a series of novel motors and pumps,based on a new type of structure called double-stator.The double-stator structure can be used as pump or motor just based on the application requirements.A certain amount of pumps or motors can be formed in one shell,and these sub-pumps or sub-motors can work alone or be combined without influence on each other.So this kind of double-stator pump(motor) is called a multi-pump(multi-motor).Through the analysis of multifarious connection modes of the double-acting double-stator multi-pumps and multi-motors,the mathematical expressions of the output flow rate and the rotational speed are acquired.The results indicate that a quantity of different flow rates can be provided by one fixed-displacement multi-pump under the condition of unalterable driven speed by electromotor.Likewise,when supplied by settled input flow,without complex variable mechanism,the functions of double-speed,multiple-speed,and even differential connection can be obtained by employing the use of a double-stator multi-motor.The novel hydraulic transmission is made of such a double-stator multi-pump and multi-motor,and has broad application prospects.De-sheng WEN Zhi-li WANG Jun GAO Yong ZHANG Shi-jun LV Tetsuhiro TSUKIJI 2011Journal of Zhejiang University-Science A(Applied Physics & Engineering)2011,12,4:23
20Optimal consumption-leisure, portfolio and retirement selection based on α-maxmin expected CES utility with ambiguity显示文摘This article studies optimal consumption-leisure, portfolio and retirement selection of an infinitely lived investor whose preference is formulated by α-maxmin expected CES utility which is to differentiate ambiguity and ambiguity attitude. Adopting the recursive multiple-priors utility and the technique of backward stochastic differential equations (BSDEs), we transform the α-maxmin expected CES utility into a classical expected CES utility under a new probability measure related to the degree of an investor's uncertainty. Our model investigates the optimal consumption-leisure-work selection, the optimal portfolio selection, and the optimal stopping problem. In this model, the investor is able to adjust her supply of labor flexibly above a certain minimum work-hour along with a retirement option. The problem can be analytically solved by using a variational inequality. And the optimal retirement time is given as the first time when her wealth exceeds a certain critical level. The optimal consumption-leisure and portfolio strategies before and after retirement are provided in closed forms. Finally, the distinctions of optimal consumption-leisure, portfolio and critical wealth level under ambiguity from those with no vagueness are discussed.FEI Wei-yin 2012Applied Mathematics(A Journal of Chinese Universities)2012,27,4:23
