In power quality monitoring, the thesis puts forward a method of power quality on-line monitoring system design based on GPS to improve the sampling accuracy of data in different spots. Meanwhile, the micro processor - TMS320LF2407A produced by TI company is chosen as the main control chip to meet the characteristics of the large quantity of data, and it introduces the hardware of working principle,...
A construction project is of dual characteristics which are product nature and process nature. In the study of environmental impact from a construction project, the traditional component approach can only measure the environmental impact of process nature without the one of product nature. A method of ecological footprint for construction project (EFCP) is put forward, including concepts, composition,...
Support vector machine (SVM) is discussed to use for recognizing cucumber leaf diseases in this paper. Considering that it is a small number of samples, a new experimental program has been proposed which takes each spot of leaves as a sample instead of taking each leaf as a sample. In the experiments Radial Basis Function (RBF), polynomial and Sigmoid kernel function were also used to carry out comparative...
This paper proposes a dynamic Probabilistic Priority Adaptive Time-Threshold-based bandwidth allocation Scheme for Multimedia services (PPATTSM) in cellular networks. Because future data service will occupy a large portion of all services in next generation mobile networks and forced termination of an ongoing call is clearly less desirable than blocking of a new call attempt, there is much significance...
Fuzzy preference relationship models based on group decision making are introduced in this paper. Firstly,we discuss the relationship between evaluation models and fuzzy preference relationship models, and give four definitions and four theorems and information fusion method of fuzzy preference relationship models. And then we analyse the Employee performance evaluation model by using fuzzy preference...
Controlling robot manipulator is essential problem to guarantee the robot execute the desired task with minimum error. This paper presents a fuzzy logic controller (FLC) for manipulating 5DOF robot arm based on independent joint control method. The proposed controller design aims to overcome the drawbacks of classical PID controller. The simulation is done using Matlab/ SIMULINK by comparing the performance...
For image-based mapping we need clip, stitching and projection transformation to the images of GE and get accurate registration with other types of geographic information. This paper analysed the layered organizing method of GE images. Through processing the GE images and getting pixel value the transformation of Mercator projection and Gauss projection and the resample method of image pixel are studyed...
To promote a fractal algorithm from being suitable for global optimization only on three dimensional spaces to an n dimensional space, this paper presents a simple and convenient method for dividing an n-dimensional hypercube. A key problem is then solved to develop the fractal algorithm in a high dimensional space so that the fractal algorithm becomes a generalized global optimization algorithm....
The order parameter is the key factor of synergetic pattern recognition. However, the conventional methods of reconstruction of order parameters have some shortcomings which limit the applications in real world. With these reasons, in this paper, a new approach to reconstruction of order parameters is proposed based on orthogonal polynomial, and thus we can make full use of the self-learning ability...
To improve the fault tolerance of the distributed spanning tree (DST) structure, we present an improved DST structure through orderly storing the elements in groups. Further, we give a representative selection rule, and based on which the node arrival and departure algorithms are proposed to balance the distribution of representatives in the structure. The maximal difference of the probabilities of...
The three-Dimensional models of parts are the basis of virtual maintenance. In this paper, a three-Dimensional modeling system based on laser scanning is designed, and a novel calibration method is proposed. In calibration, a standard ball with known dimension is translated linearly and cut by the laser plane. The profile of the laser stripe is detected in subpixel precision. And sufficient accurate...
Econstructing algorithm is able to reconstruct complex fields without any filter. It was named Simple Self-correlative algebraic reconstruction technique (SSART), which is one of nonlinear auto-adapted iterative reconstructing techniques. With numerical simulation, SSART was applied to reconstructing a complex field in order to test its converging capability. For contrast, three current representative...
