Abstract

Recent studies have shown that the wearing of soft lens may lead to performance degradation with the increase of false reject rate. However, detecting the presence of soft lens is a non-trivial task as its texture that almost indiscernible. In this work, we proposed a classification method to identify the existence of soft lens in iris image. Our proposed method starts with segmenting the lens boundary on top of the sclera region. Then, the segmented boundary is used as features and extracted by local descriptors. These features are then trained and classified using Support Vector Machines. This method was tested on Notre Dame Cosmetic Contact Lens 2013 database. Experiment showed that the proposed method performed better than state of the art methods.

Abstract

The information security is one of the most important issues in the design of any communication network.One of the most common encryption algorithms is the advanced encryption standard (AES).The main problem facing the AES algorithm is the high time consumption due to the large number of rounds used for performing the encryption operation. The more time the encryption system consumes to encrypt the data, the more chances the hackers have to break the system.This paper presents two effective algorithms that can be used to solve the mentioned problem and to achieve an effective processing time reduction using pipelined and parallel techniques to perform the encryption steps. These algorithms are based on using certain techniques to make the system able to encrypt many different states (the data will be encrypted) in the same time with no necessity to wait for the previous encryption operation to be completed. These two algorithms are very effective especially for big data size. This paper describes in detail the AES encryption system algorithm and a detailed explanation for the proposed algorithms. Moreover, the research shows the implementation of the three algorithms: the traditional, the pipelined, and the parallel algorithms, and finally a comparison between them.

Abstract

This paper presents a Flower Pollination Algorithm (FPA) to solve Dynamic Economic Load Dispatch (DELD) problem with valve-point effects and piecewise fuel options. DELD aims to find out optimum generation schedule of the committed generating units over a certain timing period, sustaining practical constraints and power demands in each interval. Due to the valve-point effect and piecewise fuel options DELD becomes as complex problem, hence in order to achieve the cost reduction and satisfying the dynamic behaviour of the generating units proposed algorithm presented.  The practicality of the proposed method is evaluated by performing simulations on standard 10-unit and 19-unit Indian utility systems for a 24 h time schedule at various load patterns. The simulation results attained by the FPA are related with other previous published techniques of the biography. These results clearly show that the proficiency and robustness of the proposed FPA method for resolving the non-linear constrained DELD problem.

Abstract

The integration of the fixed wired network and wireless mobile ad hoc network can be used to eliminate dead zones in the wireless network, and can also be used to extend the coverage of wireless networks. The integration of wired and wireless networks also known as hybrid networks, is gaining popularity due to its usefulness and practical use. Real time applications in hybrid network need some suitable quality of service. The quality thresholds are imposed on parameters like delay, jitter, packet loss and throughput. This paper utilizes the Extended AODV routing protocol for communication between MANET and fixed wired network and IEEE 802.11e MAC function HCF Controlled Channel Access (HCCA) to support quality of service in hybrid network. The performance of extended AODV, with HCCA (IEEE 802.11e) and without HCCA (IEEE802.11) is compared using simulation for real time voice over IP traffic. The extensive set of simulations shows that extended AODV with HCCA provides the drastic reduction in jitter compare to without HCCA.

Abstract

Due to the rapid scaling of Complementary Metal-Oxide-Semiconductor (CMOS), the structure of the planar MOSFET approaches the scaling limits when the short channel effects (SCEs) become the main problem. The Double-Gate and Gate-all-Around nanowire MOSFETs are said to be the promising candidate to replace the planar MOSFET in order to pursue CMOS scaling. Therefore, this paper present the result of device simulation using Silvaco TCAD tools for Double-Gate and Gate-All-Around nanowire MOSFETs. The purpose of this simulation work is to compare the performance of GAA nanowire and DG MOSFET and then study the effect of physical parameter on electrical behavior for both devices. The result of the simulated model of Gate-All-Around nanowire is compared with published data.  It was found that when the gate length of DG was scaled from 80nm to 10nm, the subthreshold slope is increasing from 62mV/dec to 162.7mV/dec. While for GAA, the subthreshold slope is increasing from 65.8mV/dec to 127mV/dec. The threshold voltage in DG and GAA at Lg=80nm are 0.40646V and -0.17505V respectively. Even though heavy doping was good for suppressing SCE, the lower doping concentration is desirable as the DG and GAA nanowire had higher on-state currents with 1.42x10-3Aand 3.23x10-4A respectively. It also showed that the threshold voltage of DG and GAA nanowire increase from -0.0734V to 0.2312V and -0.0319V to 0.2232V respectively when the channel doping is varies from lower to higher concentration.

Abstract

Technology scaling increases the density and performance of nanometer circuits, resulting in both large dynamic and leakage dissipations. This paper presents power-gating scheme, modeling, and optimization of adiabatic flip-flops operating on near-threshold regions to reduce both dynamic and leakage dissipations. The power-gated logic blocks are realized with complementary pass-transistor adiabatic logic with the dual threshold technique to reduce active leakage dissipations. The improved complementary pass-transistor adiabatic logic circuits are used as the two-phase power-gating switches to reduce the sleep leakage dissipations. The analytical model for power-gating adiabatic sequential circuits was constructed, and the energy overhead of the proposed power-gating scheme was analyzed in detail. Near-threshold computing for a power-gating adiabatic mode-10 counter was verified. The results show that the proposed power-gating technique is suitable for the adiabatic units operating on near-threshold regions. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3378

Abstract

Electric fault is the main challenge in the process of providing continues electric supply. Fault can occur at anytime and anywhere. Due to the fault causes are mainly based on natural disaster or accident. Most fault occurrence hardly predicted nor avoided. Therefore, a quick response fault detection is necessary to ensure that the fault area is maintained to ensure a continuous power supply system. Hence, a system is required to detect and locate the position of the fault in the power system especially in the transmission line and distribution line. This paper will review the type of fault that possibly occurs in an electric power system, the type of fault detection and location technique that are available together with the protection device that can be utilized in the power system to protect the equipment from electric fault.

Abstract

Accurate mine slope surface deformation forecasting can provide reliable guidance for safe mining production and mine construction planning, which is also important for the personnel safety of the mining staffs. The mine slope surface deformation forecasting is a non-linear problem. Generalized regression neural network (GRNN) has been proven to be effective in dealing with the non-linear problems, but it is still a challenge of how to determine the appropriate spread parameter in using the GRNN for deformation forecasting. In this paper, a mine slope surface deformation forecasting model combining artificial bee colony optimization algorithm (ABC) and generalized regression neural network was proposed to solve this problem. The effectiveness of this proposed forecasting model was proved by experiment comparisons. The test results show that the proposed intelligent forecasting model outperforms the BP neural network forecasting model, BP neural network with genetic algorithm optimization (GA-BPNN) and the ordinary linear regression (LR) forecasting models in the mine slope surface deformation forecasting. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4815

Abstract

The use of renewable power sources, like wind power, has been increased recently due to climatic changes caused by fossil fuels and fast depletion of fossil fuels. This has lead to the tremendous increase in the interconnection of wind turbines to power system grid. This interconnection on a large number in to grid causes problems such as power quality, maintaining system voltage, reactive power compensation, control of grid frequency and aspects of power system grid stability. In this proposed scheme, a fuzzy logic based controller is employed for a STATCOM to improve the power quality. The proposed control scheme supplies the required reactive power to the system and thus relieves the source, leading to Unity Power Factor (UPF) at the source and also it injects currents to reduce total harmonic distortion (THD) to satisfy IEC standard. For extracting the reference currents, a power balance theory based control algorithm is employed. To determine the effectiveness of the proposed fuzzy logic controller, a comparative analysis is also performed with a PI controller and the results have been presented.
