Abstract

Mean shift algorithm is widely used in 2D images. In this paper a novel 3D corresponding control points estimation using mean shift algorithm is proposed. This algorithm is not a simple extension from 2D to 3D, but computes the probability density function in each slice of the search region and connects them into a whole density function smoothed by Gaussian function. And then we calculate and compare Bhattacharyya coefficients to determine a new location of the trace point. A cylinder instead of ellipsoid is utilized as the search region to improve tracking accuracy. Also three revising methods different from the direct round-off way are proposed to modify the floating trace point. Experiment demonstrates the feasibility of this 3D mean shift algorithm and the effectiveness of the three revising methods. DOI:http://dx.doi.org/10.11591/telkomnika.v10i5.1286

Abstract

For the lack of real-time performance of browser technology in existing Web-based real-time monitoring system, takes use of SVG (Scalable Vector Graphics) and the Comet to design a new Web-based real-time monitoring system. In this system, JSON (JavaScript Object Notation) is the data transmission carrier, Comet is the key technology for system communication and data transmission, and SVG is a chart drawing tool in the browser side. So this system has a good real-time and is rich in the form of show. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1347

Abstract

In order to study the steady-state electromagnetic forces acting on the stator end-winding in a multi-phase induction machine during the operation, we conducted a 3-D electromagnetic and mechanical sequential coupling analysis to analyze the stress and the deformation. Both of them are done by the finite-element method. Meanwhile, the geometry of the nose portion is modified for the limited computer resources. The result shows the nose part of the coil ends experiences larger displacement, but von Mises stresses are larger in the straight part. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1283

Abstract

When the pathologies are in the close vicinity of the lung wall, the acquisition of the pulmonary nodules depends on accurate segmentation of the lung fields. However, the traditional methods based on pixels intensity can not segment out them correctly. The paper proposes an effective segmentation method based on primary component analysis(PCA) manifold. It used the lung fields relationship in a lung to construct the shape manifold with B-spline interpolation. In the manifold space, according to the position of the affected lung field, a measurement had been used to find an amended position, and it was projected back into the shape space to reconstruct the prior shape. The shape was registered with the affected one and then segmented the original lung section to obtain the correct lung field. The experiment results illustrate that the proposed method has a more correct segmentation ability than the methods based on rolling-ball and pixel intensity. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1266

Abstract

Time-table problem is a classical NP-complete problem. Algorithm of DNA computing for time-table problem was obtained with introducing the technology of AcryditeTM gel separation. Each class period viewed as a graph vertex was mapped into DNA molecules chain. With the probe coding, the gel column was constructed to arrange the order of DNA chain through biological reaction. The problem was solved by gel column that performs the basic core processing and extraction that makes the result visible. The minimum number of cycles of arrangement was the minimum number of class hours. The simulation results show that the algorithm compared with others is very easy and feasible. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1271

Abstract

This paper represents the GSA that can be used to determine the optimal location and rating of FACTS devices. They are devices used to regulate and improve the power flow in the power system. The method used in this study was GSA. FACTS types used were TCSC implemented on 500kV Java-Bali Power System. Load flow results before optimization showed that the active power loss was 297.607MW. While the load flow results after optimization using GSA with 5-TCSC obtained were 287.926MW of active power loss, with 10-TCSC, it was obtained 281.143MW of active power loss. In addition, using 15-TCSC, the active power loss obtained was 279.405MW. GSA methods can be used to minimize power losses and transmission lines as well as to improve the value of the voltage in the range of 0.95+ 1.05pu compared with load flow results before optimization. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1183

Abstract

Traditional genetic algorithm trapped into the local minimum easily. Therefore, based on a simple genetic algorithm and combine the base ideology of orthogonal design method then applied it to the population initialization, using the intergenerational elite mechanism, as well as the introduction of adaptive local search operator to prevent trapped into the local minimum and improve the convergence speed to form a new genetic algorithm. Through the series of numerical experiments, the new algorithm has been proved to be efficiency. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1265

Abstract

A novel discriminative supervised neighborhood preserving embedding (DSNPE) method is proposed for feature extraction in classifying hyperspectral remote sensing imagery. DSNPE can preserve the local manifold structure and the neighborhood structure. What’s more, for each data point, DSNPE aims at pulling the neighboring points with the same class label towards it as near as possible, while simultaneously pushing the neighboring points with different labels apart from it as far as possible. Experimental results on two real hyperspectral image datasets are reported to illustrate the performance of DSNPE and to compare it with a few competing methods. DOI:http://dx.doi.org/10.11591/telkomnika.v10i5.1346

Abstract

Euler-Lagrange (EL) model of voltage source PWM rectifier is set up based on its model in synchronous dq coordinates. Passivity based controller is designed on the basis of passivity and EL model of voltage source PWM rectifier. Three switching function are educed by passivity based controller. A switching function is only realized in engineering consequently. Voltage source PWM rectifier using passivity based controller has many advantages, such as simpler structure, low total harmonic distortion, and good disturbance rejection performance. Passivity based control law is proved feasible by simulink simulation. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1343
