Abstract: To overcome the shortcomings of Particle Swarm Optimization (PSO), an Adaptive Mutative Scale Chaos Particles Swarm Optimization (ACPSO) based on Logistic Mapping was proposed. The chaos method was used to initialize the particles. The adjustment method of the inertia weight depended on the particle’s fitness; it could avoid premature convergence for the particles. When the particles fell into the local optimum, mutative scale chaos optimization strategy was adopted to adjust the optimal particles. To test the effectiveness of the algorithm, three representative algorithms were compared with. The results show that the algorithm has high convergence speed and high precision.26Jag8879环亚手机|首页主页

Abstract: It is already proved that the traditional fixed time step lattice Monte Carlo (LMC) algorithm can reproduce both the mean and the variance of the particle displacement exactly. However, there is always a non-zero skewness when there is a drift. To further improve the accuracy, a new LMC algorithm of biased diffusion model with five transition probabilities has been devised, which indeed reproduces the first three moments exactly. The valid scope of lattice step and time step can be determined numerically once the drift and the diffusivity are given. A new measurement is introduced to study the accuracy characteristics of the new algorithm. As a result, a particular lattice step can be discovered in which case the first step error is the maximum error in the simulation tests. Then, given the particular lattice step, the optimal time step can also be found to minimize the maximum error.26Jag8879环亚手机|首页主页

摘要:已证实传统定时间步长LMC算法,能准确复现粒子分布的均值和方差。而存在漂移时,总产生非零的偏度。为进一步提高精度,设计了具有5个转移概率的新LMC有偏扩散模型算法,且新算法能准确地复现分布的前三阶矩。一旦给定漂移速度和扩散率,有效网格和时间步长的范围就能够数值计算出来。引入了一种新的度量方法来研究新算法的精度特性。从而发现了一个特殊的网格步长,能让算法仿真的首步误差是最大误差。在该网格步长下,也能发现最优时间步长,使得最大误差达到最小。26Jag8879环亚手机|首页主页

Abstract: A method was proposed to reconstruct high-dimensional full-body motion sequences from low-dimensional control data collected by sparse inertial sensors. The approach solved the mapping problem from low dimension to high dimension. A numerical similarity- geometrical similarity-time continuity model was setup to ensure the reconstructed motion candidates in numerical-logical similarity. The gap between angle and angular acceleration was eliminated by acceleration reconstruction. An energy function was introduced to optimize the reconstructed results which guaranteed the accuracy. The analysis and comparison experiments show that the proposed method can reconstruct nature and credible motions in real-time and can be applied in low-cost full-body motion capture by using few inertial sensors.26Jag8879环亚手机|首页主页

Abstract: To analyze the vibration performance of the ball screw drive system, the finite element model (FEM) of the simplified system by Ansys/Workbench was given to acquire the vibration mode and shape. Based on the vibration shape calculated from FEM, a set of hybrid basis function was used to generate the new Ritz series for building the system motion equation of the axial and torsional vibration. The pitch of the ball screw was considered in the method. A mathematical model which was easy to design the controller was developed. Through the numerical simulation, the modal characteristics and shape of system under the circumstance of different worktable locations were given. The results reveal that the location of the worktable has a large influence on the axial mode and less effect on the torsional vibration. The experiment result shows that the proposed modeling method can accurately predict the vibration characteristics for the ball screw drive system.26Jag8879环亚手机|首页主页

Abstract: In the view of problem in lack of information sharing mechanisms at the semantic level among processes, a business process modeling algorithm based on ontology language using concept hierarchy as background knowledge was proposed. The business process modeling by traditional business process languages can be transferred to ontology language (OWL) description so as to realize the semantic sharing of business process. The approach has two main advantages compared with traditional methods: (1) accelerating the building process, minimizing the conversion cost; (2) background knowledge guides the extraction of knowledge resided in database. As a way of validating the approach, part of the sales order process adopted from SAP reference process models was used to construct business process ontology, to validate the method. The gold standard experiments show that this method can correct and effectively construct process ontology.26Jag8879环亚手机|首页主页

Abstract: Travel time prediction of urban road is a significant support for urban intelligent transportation system. Four types of LSTM neural network architecture were selected to predict the urban road travel time. The number of nodes in the LSTM hidden layer was fixed to determine the optimal input length of the model. The input length of the model was fixed and the predictive performance of the four LSTM models under different hidden layer nodes and considering spatial correlation were tested respectively. The performance of spatial LSTM model was compared with four traditional models, for example, BP neural network. The results show that the LSTM model with spatial correlation has better fitting and training ability than the four traditional models.26Jag8879环亚手机|首页主页

Abstract: Under small world network structure, this research constructed a contagion model of cooperative behavior based on behavioral characteristics such as homogeneity gathering, two degrees of separation, influence paradox, attenuation nature, etc. and used Netlogo platform to run the simulation. The results indicate the contagion of cooperative behavior has hysteresis, emergent and progressive properties; the average path length constrains the contagion completion; the strong ties are prone to spread cooperative behavior; the distribution level of node degree of network significantly impacts the contagion time. The discoveries afford guidance for enhancing cooperation performance in small groups, by adjusting relationship links among members, shortening average path, strengthening critical relationship ties, and fostering the cooperative behavior emergence and the systematic cooperative characteristics.26Jag8879环亚手机|首页主页

Abstract: 3D data intuitively reflects the full view of the target or scene. Time of Flight (ToF) camera is a range imaging sensor that can provide 3D geometric information of targets immediately, thus it is widely applied in the robot positioning and navigation, 3D reconstruction and other aspects etc. Due to the operational principle of the camera itself, there are variety measurement errors of the source data obtained by ToF, resulting in image distortion. The measurement errors in the imaging process of ToF camera were analyzed and summarized, and the cubic spline interpolation method combined with look-up table was proposed to segment the compensation of the nonlinear depth offset to realize the adaptive error compensation process. A data correction model based on the pinhole model was proposed to tackle the data errors appeared during the process of coordinate transformation from Spherical Coordinate System to Cartesian Coordinate System, to restore the real scene more accurately. Experiment results show that the corrected depth data error and offset are effectively improved.26Jag8879环亚手机|首页主页

Abstract: In cognitive radio networks, the energy consumption in the process of spectrum sensing is the hot spot of research. A unified framework for modeling based on Poisson process was developed which could be used even under interference limited to count the energy consumption, thereby obtaining a spectrum sensing energy consumption. Spectrum sensing energy as the function of the number of secondary users in cognitive radio networks, their spatial density and the number of hops, could be modelled as a truncated gamma distribution. This model is used to statistically analyze cognitive users’ energy consumption in the process of spectrum sensing under the circumstance of temporal perception, spatial perception and temporal - spatial joint perception. Simulation and analysis results show that the model is of scientific rationality.26Jag8879环亚手机|首页主页

Abstract: To solve the problems of the narrow-band signal DOA method, such as low resolution and unsuitable for applications with small number of snapshot and array elements, etc, DOA of uniform circular array based on improved smoothed l0 norm was proposed after analysis of the characteristics of UCA model and signal airspace sparse, combining with improved the smooth l0 norm algorithm. For reconstructing the signal, the method used the combined continuous function as the approximation to l0 norm by sparse matrix processing array manifold, which improved the convergence speed. It was also extended to the UCA DOA estimation, which avoided feature decomposition and spectral peak searching process. On the premise of guarantee the estimation precision, the calculation and the number of the array were effectively reduced. The feasibility and effectiveness of the method were verified by the experimental simulation.26Jag8879环亚手机|首页主页

摘要:针对基于SIFT特征匹配的图像检索方法忽略空间位置信息的缺陷,提出了基于空间位置信息加权词汇树的图像检索方法。利用分层词汇树将图像SIFT特征量化为视觉单词,将图像匹配转换成视觉单词权值向量匹配。由于单纯的视觉单词权值向量匹配忽略了视觉单词之间的相互位置影响,生成SIFT点的空间位置影响信息,根据SIFT点与视觉单词之间的从属关系,将SIFT点的空间位置影响信息聚类为视觉单词之间的位置影响,将视觉单词的空间位置信息作为加权系数,加入到视觉单词的权值匹配中去,细化特征之间的匹配得分通过相似度排序检索相似图像。实验结果表明,该算法能有效提高图像检索的精确度。26Jag8879环亚手机|首页主页

Abstract: Aiming at the positional information ignorance problem in image retrieval based on SIFT feature matching, an image retrieval approach using weighted vocabulary tree based on the spatial location information was proposed. The vocabulary tree is used in the method to quantify SIFT features as the visual words, converting the image match into the visual words' weight vector match. Because only visual words’ weight match ignored the mutual position effect, SIFT points’ spatial location information was generated, and was classified into the position effect of visual words according to affiliation between SIFT points and visual words. The spatial location information of the visual words was used as the weighting factor of weight vector matches, refining the matching score between features. Similar images were retrieved by similarity sort. The experimental results show that the algorithm can effectively improve the accuracy of the image retrieval.26Jag8879环亚手机|首页主页

Abstract: Distance measure is a basic and crucial notion of set theory. Since the intuitionistic fuzzy sets (IFSs) were put forward, distance between IFSs has been widely concerned by some researchers and many types of measures have been proposed. Most of them have counter-intuitive cases and ignore the characteristics of three parameter properties of IFSs. The concept of fuzzy distance was introduced, which embodied the characteristics of classical distance and highlights the characteristics of hesitance index simultaneously. A new fuzzy distance measure was proposed, and the corresponding proof was included. An artificial benchmark test set of distance measure was constructed based on single-element IFSs, which was applied to compare the proposed distance measure with the widely used distance measures. Results show that the proposed distance does not provide any counter-intuitive cases and the waver that brought from hesitancy degree can be well reflected.26Jag8879环亚手机|首页主页

Abstract: The viewpoint selection is to automatically select one or more approximate optimal viewpoints in the viewpoints of multiple views, at the same time, it is related to the evaluation of the quality of the viewpoint. 3D visualization best viewpoint selection method based on particle swarm optimization algorithm was proposed. The viewpoint quality was evaluated by using the image information entropy and the image edge entropy, and the viewpoint was selected by the multi-objective intelligent optimization method. The basic flow begins with the initial viewpoint set, finding the best viewpoint by means of coding, particle evaluation, and particle update, which is a process of multiple iterations until a satisfactory viewpoint is found or the iterations are maximized. Experiments show that the method is effective and can automatically select the best viewpoint, which can effectively reduce the number of artificial test selection.26Jag8879环亚手机|首页主页

Abstract: The strong coupling of the hypersonic vehicle, the high order of the model, and the perturbation of the aerodynamic parameters make it difficult for the general controller to achieve the desired control effect. The self-disturbing tandem technique can well meet the requirements of the high-order model control.

Abstract: Based on the theory of complex networks, the structure and characteristics of joint operational network information system (JONIS) were analyzed from the perspectives of heterogeneous directional weighted network topology, strong degree and its centralities. It is found that the combat network based on JONIS has characteristics of small-world and scale-free, with a large average weighted aggregation coefficient and a small average weighted path length, showing a similar power-law distribution. In the example network, command centers, satellites, support force, and early warning unit all have larger strong degrees and centralities. These platforms as the center of gravity and fragile nodes in the JONIS should be focused on protection.26Jag8879环亚手机|首页主页

Abstract: Large scale water is an integral part of nature and of high interest for interactive 3D applications, e.g., computer games and virtual environments. Allowing the water to interact with floating objects is essential for applications, but traditional height field interaction methods concentrate on water-to-body effects by letting water flow through the bodies. A novel GPU-based method for rapid simulation of large scale water interacting with objects was proposed. A specially designed simulation grid was used to solve the interactions between dynamic objects and the surrounding environment. The model of rigid body was realized with a pre-rigid body method. The method runs in real time for large areas of water even with a very limited GPU budget.26Jag8879环亚手机|首页主页

Abstract: Lane restriction strategy for trucks is an effective way to improve the capacity of expressways and ease traffic congestion. Microscopic simulation models were employed to assess the impacts of restriction strategies and truck accidents on expressway traffic condition. Parameters were calibrated and validated based on the field data of Jingzang Expressway. Five simulation scenarios with different time setting for trucks’ no passing were established, and evacuation after truck accident was simulated. Simulation results indicate that the most suitable time for trucks’ no passing is from 7:00 to 19:00. The travel time of small passenger cars can be reduced by 10%, and all the trucks can be evacuated from the expressway before 8:00. The other scenarios can lead to trucks’ retention, affecting the traffic conditions in the morning peak hours of the next day. Truck accidents could result in the delayed vehicles’ lining along the expressway.26Jag8879环亚手机|首页主页

Abstract: Extreme Learning Machine (ELM) is a novel learning algorithm for Single-Hidden-Layer Feed Forward Neural Networks (SLFN) with much faster learning speed and better generalization performance than traditional gradient-based learning algorithms. However ELM tends to require more neurons in the hidden layer and lead to ill-conditioned problem due to the random selection of input weights and hidden biases. To address these problems, a learning algorithm was proposed which used quantum-behaved particle swarm optimization (QPSO) to select the optimal network parameters including the number of hidden layer neurons according to the both the root mean square error on validation data set and the norm of output weights. Experimental results on benchmark regression and classification problems have verified the performance and effectiveness of the proposed approach.26Jag8879环亚手机|首页主页

Abstract: A Model of 300 MW thermal power unit’s governing system of steam turbine is established to analyze its load fluctuation during main steam valve activity test. The model contains three sub-models; they are the model of turbine’s governor during main steam valve activity test, the model of electric-hydraulic servo actuator, and the model of turbine considering governing valve’s discharge characteristic. The analyses on these models indicate that mismatch among control model, configuration of DEH (Digital Electric Hydraulic Control System) and characteristic of the unit is the cause of load fluctuation. Through simulation, the method for load fluctuation suppression was determined. Result of actual main steam valve activity test based on the method shows that load fluctuation is obviously suppressed after control optimization.26Jag8879环亚手机|首页主页

Abstract: The process and method of model-based system engineering (MBSE) and its implementation in highly complex flight control system were clearly introduced. By comparing with traditional design methods, MBSE applied models as baseline instead of documents to handle the complexity of modern systems. The top-down workflow is more capable of ensuring coherence of design process, completeness of requirements verification and system testability. With the simulation of system model, the integrality of design and verification process, system function behavior simulation, implementation of the failure mode, effect analysis (FMEA) and the decreasing of system risk grade are well achieved.26Jag8879环亚手机|首页主页

Abstract: Zero Crossing Detection (ZCD) and phase locked loop are widely applied in the real-time control. Compared the performances of ZCD, SSRF SPLL and DDSRF SPLLa method named as Single Phase Self Decoupling SPLL (SPSD SPLL) for HSSS(Hybrid Solid State Switch) is proposed and the mathematical method and control methods are given. The control parameters were obtained by analyzing the steady and dynamic performance of SPSD SPLL. By establishing the real-time controlling models based on the above strategies and HSSS model in the MATLAB/Simulink, the simulation and optimization analysis results verified that the SPSD SPLL was well performed under different working conditions, the SPSD strategy could realize the basic functions of HSSS, and the requirement of real-time control could be satisfied.26Jag8879环亚手机|首页主页

Abstract: Low frequency broadband signals have advantages in improving radar target recognition ability. To determine the ground reflectance of broadband signal at low altitude, the ground reflectance of different frequency points of narrowband is used to compose the equivalent ground reflectance of broadband signal based on ground reflection model. The relationship between ground reflectance and ground characteristics (relative dielectric constant, conductivity), grazing angle, and polarization characteristics were discussed in detail. The reflectance in typical environment was verified using the method of antenna pattern test at low altitude. Results show that the reflectance simulation model was effective, and the model provides theoretical basis for broadband radar target detection.26Jag8879环亚手机|首页主页

Abstract: A new method based on fourth-order cumulant and propagator method for the joint estimation of the range and DOA of spatial near-field sources is presented. The fourth-order cumulant matrix is constructed using the received uniform linear array data, the received signal noise subspace is estimated by propagator method; the range and DOA of spatial near-field sources are gotten through the spectrum peak search method after the MUSIC spectrum function construction. Compared with the traditional MUSIC algorithm, the presented algorithm with the propagator method directly estimates the least squares solution of the noise subspace, rather than conventional orthogonal solution of singular value decomposition algorithm. Although the estimation performance of the presented alogorithm is slightly inferior to the traditional singular value decomposition algorithm, it has lower computational complexity. The simulation results show the proposed method is effective.26Jag8879环亚手机|首页主页

Abstract: Due to large scale wind power integration, heat supply units hardly meet the AGC (automatic generation control) requirement by the existed coordinated control system. It is necessary to analyze coupling characteristics of thermal and electric load thoroughly. A transfer function matrix including characteristics of heat supply part was gained by small deviation linearization of a dynamic unit’s model. Coupling characteristics was analyzed based on variable pairings of the existed coordinated control system and decouplers were designed. Relative gain matrix measure and simulation were used to compare the coupling extent before and after decoupling. Simulation experiments show that adding static decouplers to basic boiler-following control scheme can decrease the power load disturbances effectively which are caused by thermal variation.26Jag8879环亚手机|首页主页
