For the problem that poor quality of particle and large amount of computation, a particle filter tracking method based on adaptive optimization is presented by using color clue of object. In our method, 24-bit color pixels are used to establish a kernel histogram of object model, and then adaptive models are built according to Bhattacharyya coefficient of object model in previous frame. In addition,...
This paper deals with chaos of nonlinear dynamical system of the Permanent Magnet Linear Synchronous Motors (PMLS -M),and a new chaotic simulation model is proposed by mathematical transformation. Under certain conditions,chaos of Permanent Magnet Linear Synchronous Motors appears by simulation,which provide an important research basis for the control and further analysis of chaotic behavior of Permanent...
In order to increase the flexibility of control for stepper motor, a pulse generator based on FPGA is proposed in this paper. Draw State transition diagram by analysis the Principle of pulse generator, and realized in FPGA using Very High-speed Integrated Circuit Hardware Description Language (VHDL). The simulate results show that pulse output in FPGA is consistent with the requirements. The module...
In this paper, the spatial six-DOF(degree of freedom) parallel manipulator is described as a rigid body, and in many cases, this simplification is adequate for describing the properties of the whole mechanical system, especially with large and heavy motion system. By using Kane approach the explicitly forward dynamic equations with six variables are gained straightly and readily. Under identical conditions,...

It's control device, with 8 bit single chip computer STC89LE516AD as its core, assisted by data acquisition circuit, data storage circuit, and data communication circuit, performs the function of collection, storage and communication of the driving information. Furthermore, with the help of visual...
In this paper, a bipartite scientific collaboration network is constructed to identify the vital researchers in a scientific research group. There are two kinds of vertices in the network, where one kind of vertices represent the researchers and the other ones illustrate the papers. The edges are connected to the vertices which belong to two different classes. Through the bipartite network, a model...
The experience is everything, and we have never had so much experience to try. Mobile internet experience has become one of the new experiences in life. Firstly, this article describes the use intention of mobile Internet in China which both quantity of Chinese mobile internet users and using frequency are low. Secondly, based on TAM and flow experience theory this article builds a model of the mobile...
In this paper, the numerical simulation and experimental study are both used to solve the issue about the A2/O activated sludge process of one wastewater treatment plant. By the application of the standard model and moving-mesh method of the FLUENT, the velocity maps were got finally. The optimum scheme was found by the comparison of the maps in different scheme. The experimental model was set on...
Most of the inventory models under delay in payments only considered the relationship between the manufacturer and the retailer. However, in practice, the retailer also provides the customer with the credit period to stimulate demand. A three-echelon supply chain system with one manufacturer, one retailer and one customer is presented in this paper. From the perspective of the retailer, fuzzy inventory...
Multi-sensor information fusion (MSIF) is an emerging technology, which has received great attention. A recent achievement about the MSIF-based filtering and control is summarized, which includes the MSIF filter and MSIF control. The filtering algorithm, the linear and nonlinear fusion control, and economic system control are extensively reviewed. Some typical application results of MSIF are given,...
For the system of macro micro-feed table, deformed guide rail joints is designed using of flexible hinge. The 2D stiffness matrix is derived from principle of minimum potential. And the stiffness matrix is applied to micro-feed table which contains deformed guide rail joints. The simplifying computation model of the micro-feed table is obtained. The results of simplifying model are compared with finite...
In order to solve engineering measures can not stop the decreasing water resources, proposed a method of hydrological impact of based on water rights under the conditions of conversion. A basin is modeled using a water balance approach for each of the primary water use areas within the basin, employing a yearly time step. The basin hydrologic planning model was developed to aid in understanding how...
Competitiveness measurement of ports should consider all internal and external factors. In this paper, we use a number of quantitative measurement indicators to evaluate the actual situation of Shenzhen port. By using factor analysis model, a small number of common factors are extracted to represent the large number of measurement indicators. Furthermore, this paper computes the evaluation scores...
Efficient concept lattice generation algorithm is a major problem for the applied research of formal concept analysis. Based on the basic property of concept, this paper put forwards and proves a theorem about the relationship of concepts, and then proposes an incremental concept lattice algorithm based on basic concepts. An example shows that the algorithm is feasible and effective.
The environment of information dissemination is represented by complex network. The information here can represent viruses in the network, advertisements, hot topics, public opinions , rumors and so on. A new mathematical model describing the propagation process of information in the complex network is proposed using multi-agent simulation and discrete event simulation methods. The model is developed...
An integrated strategy coupling GIS with two-dimension hydrodynamic model is explored to simulate the flooding inundation in the upper reaches of Huangpu River. DEM data, hydraulic engineering map and other available geospatial data are used and aid to generate the computational grid, while, some treatments of interior and exterior boundary conditions, and calculations of variable resistance terms...
The wind load is an important role in structure of dynamic loads. Transmission tower be often broken down with effect of the wind load, the design must consider the wind load precisely the influence. This article elaborated the wind basic characteristic foundation and inferred the linear filter method to simulate transmission tower structure turbulent wind load theory, and used the turbulence along...
The complexity of contemporary business organizations has caused the audit profession to radically alter their audit process over the past decade. Because of the impact of e-business partnerships, outsourcing and co-sourcing relationships, and co-dependence with business partners on the extending of the business risk faced by a client, auditors have to alter their procedures in accordance with this...
Given the generally low quality of Production Development schedule baseline definition, an evaluation method of project schedule risk quantification based on Monte Carlo simulation under the conditions of resource constraints is proposed. Firstly, considering the resource constraints on the progress, an activity duration sampling method under resource constraints is proposed. Secondly, to study the...
The multi-scale laser scanning technology is used to obtain the Three-dimensional (3D) data of a large pump. This technology is more accurate and faster than the traditional measurement methods when obtaining the data of complex shape entities. The data obtained from multi-scale laser scanning technology can be used in reverse engineering CAD modeling of pump. They can also be used to get the model...
