Abstract

 The existing Harris corner detection algorithm using mostly Gaussian low-pass filter to smooth image, and there are some phenomena about loss of information and location of the corner offset in images, at the same time, the single-scale Harris corner detection algorithm does not have the scale invariance. B-spline function converges to a Gaussian function, therefore we combined B-spline wavelet multi-scale theory and Harris, and proposed multi-scale Harris corner detection method based on B-spline. Firstly, we used B-spline function to smooth filter image at different scales. Secondly image and B-spline convolution template were calculated by convolution operator. Finally,we extracted alternative corner from the different scale images, and searching for the extreme value of scale space as the location and characteristics scale of the feature points within the search window template that has belonged to a fixed size at the center of Harris corner. The experiments show that the proposed method not only maintains the good performance of Harris operator, but also has scale invariance. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4797

Abstract

In this manuscript, a DC-DC converter of modified multilevel sepic model with single switch is proposed here. The designed converter combines the voltage tripler circuit, which improves the voltage gain and reduces the voltage ripple of the system. Another feature of the designed converter is reduces the voltage stress and utilized for PV based applications. The operation of the designed converter in Continuous-Conduction Mode (CCM) is discussed. The converter boosts the PV input voltage of 30 V to 400 V output voltages. The efficiency attained by the designed converter is 94%. The Theoretical analysis of the designed converter is presented and it is done with MATLAB simulink. To analyse the performance of this DC-DC converter a model was developed and tested.  From the experimental results obtained, it is analysed that the converter performs better and suitable for PV based application.

Abstract

Gravitational Search Algorithm (GSA) has recently been explored to develop a novel algorithm for distributed optimization and control. This paper proposes a dual Proportional Integral (PI) controller of Load Frequency Control (LFC) based GSA to enhance the damping of oscillations in a two-area power system. A two-area non-reheat thermal system is considered to be equipped with dual PI controller. GSA is utilized to search for optimal controller parameters by minimizing a time-domain based objective function. The performance of the proposed controller has been evaluated with the performance of the conventional PI controller, and  PI  controller  tuned  by  GSA in  order  to  demonstrate  the  superior efficiency of the proposed dual PI controller tuned by GSA. Simulation results emphasis on the better performance of the optimized dual PI controller based on GSA in compare to optimized PI controller based on GSA and conventional one over wide range of operating conditions, and system parameters variations. DOI: http://dx.doi.org/10.11591/telkomnika.v15i3.8454

Abstract

The reliable transfer in Network on Chip can be guaranteed by crosstalk avoidance and error detection code. In this paper,we propose a joint coding scheme combined with crosstalk avoidance coding with error control coding. The Fibonacci numeral system is applied to satisfy the requirement of crosstalk avoidance coding, and the error detection is achieved by adding parity bits. We also implement the codec in register transfer level. Furthermore, the schemes of codec applying to fault-tolerant router are analyzed. The experimental result shows that "once encode, multiple decode" scheme outperforms other schemes in trade-o_ of delay, area and power. DOI: http://dx.doi.org/10.11591/telkomnika.v11i1.1862

Abstract

On the basis of analyzing the shortcomings of traditional authentication mechanism synthetically, the paper presents a new kind of P2P identity authentication model. In the new P2P Identity authentication model, it authenticates the identity of nodes by using  a new Zero-Knowledge proof identification scheme which combines the advantage of RSA. Besides, during the process of validating nodes’ identity, CA (Center Authentication) doesn’t need to participate in. At last, Simulation results show that the new P2P identity authentication method can improve the safety of network effectively. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.2943

Abstract

This paper presents the effect of cantilever width on the displacement pattern for low power acoustic energy propagation. A single layer cantilever configuration is used to design the harvester with Lead Zirconate Titanate (PZT-5H). The device is designed with 10×(1 to 10)×0.62 mm dimension. The displacements of the cantilever are obtained through the simulation analysis. The maximum displacements are found of 9.80E-28 mm with the smallest width while minimum displacement is found from 5 mm width. From the results, it is obvious that, smaller width can result larger displacements, however, rectangular and square cantilever shape can be advantageous for low power applications.

Surf-riding actions in reliable attractive following oceans for cases with a variety of LCBs and Froude information are mimicked utilizing the numerical model. Comes concerning display that the surf-riding can't be forestalled by the modify of LCB. Be that as it may, it happens with an upper limit momentum when ship's focal point of lightness (COB) is stimulated towards stem contrasted with affecting towards stern, which is for the majority part since the distinctions on wave resistance brought concerning by the changing of LCB.

Abstract

Thanks to its wide bandwidth, pulsed eddy current (PEC) has attracted researchers of various backgrounds in the attempt to exploit its benefits in Non-destructive Testing (NDT). The ability of modelling PEC problems would be a precious tool in this attempt as it would help improve the understanding of the interaction between the transient magnetic field and the specimen, among others. In this work, a Finite Element Modelling (FEM) has been developed and experimental test data have been gathered for its validation. The investigated cases were simulated surface cracks of different sizes and angles. The study involved looking at time-domain PEC signals at different spatial distances from the cracks’ faces, which would particularly be useful for modelling scanning PEC probes. The obtained results show a good agreement between the FEM and experiment, demonstrating that the modelling technique can be used with confidence for solving similar problems.

Abstract

Solar Energy, the most abundant and widely used Renewable Energy is not only reliable, scalable but serves solution to global warming around the world. This energy is used for electricity generation using Photovoltaics (PV) converting Solar Energy into electricity. Photovoltaics (PV) play significant role for future Distributed and Renewable Energy Generation Systems (DG). This study is an effort to visualize simulation tool for solar cell array under rapidly changing solar radiation and temperature by inserting a test signal in the control input. The main objective is to find the parameters of the nonlinear I-V and P-V equation by locating the curve at three points: short circuit current, open circuit voltage and maximum power. Future Smart Grids can be optimized if computerized and designed using mathematical modeling and simulation system at STC. Case study relative to factors including weather and seasonal variations is tested through SIMULINK model. Predicted changes are configured for determination of MPP. The proposed model is based on variations by changing absorption of light with physical inspections for data corresponding to low and high temperatures. DOI: http://dx.doi.org/10.11591/telkomnika.v12i8.6071

Abstract

Distributed Raman sensor offers a number of advantages to the implementation of smart grid, which is aimed to improve reliability and energy efficiency as compared with traditional power grid. However, the fantastic properities of slow light are rarely considered in the former studies on the Raman sensor systems. In this paper, the effects of Raman slow-light on room-temperature single-mode optical fiber sensors are examined by extracting the Raman pulse-delay terms from extended nonlinear Schrodinger equation (NLSE). Numerical study shows that pulse parameters such as pulse position, frequency chirp, and envelope distortion may be greatly affected by slow light. Two important points of pump power are show clearly keeping the Raman pulse zero walk-off or chirp free, respectively. We demonstrate a method based on pump power adjustment for compensating the slow light induced impairment. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2472
