Abstract	In recent years, permanent magnet synchronous motors (PMSM) have gained variety industrial applications, because of simple structures, high efficiency and ease of maintenance. But these motors have a nonlinear mathematical model. To resolve this problem several studies have suggested the application of vector control (VC) and direct torque control (DTC) with soft-computing (SC) technique. This paper presents neuro direct torque control (NDTC) of PMSM using genetic algorithm (GA) speed controller. The proposed method effectiveness has been verified by computer simulations using Matlab/Simulink®. These results are compared with the ones obtained with a classical DTC using PI speed controller.
Keywords	Permanent Magnet Synchronous Motor, Neuro Direct Torque Control, Genetic Algorithm

Abstract	Adult classification of images and videos is one of the major tasks for semantic analysis of visual content. A modern approach to this problem is introducing a mechanism to prevent objectionable access to this type of content. In this paper, we propose a real-time system that can classify input videos into adult or non-adult videos. First, vidéos were filtered by skin color model using threshold technique. Then, the output videos are classified by neural network for taken the decision. We notice that the detection of an adult video is based on the detection of the adult images that compose the considered video. The simulation shows that this system achieved 90% of the true rate.

Title:	TARGET COVERAGE MANAGEMENT PROTOCOL FOR WIRELESS SENSOR NETWORK
Author:	PURNIMA KHUNTIA, PRASANT KUMAR PATTNAIK

Abstract	One of the major challenges of Wireless Sensor Network is Target Coverage Problem which is concerned with random deployment of sensor nodes for monitoring the specific targets for maximum duration. These small sized sensor nodes have limited resources in terms of energy, memory, computational speed and bandwidth; and can’t withstand extreme environmental conditions. Therefore, more number of sensor nodes are deployed than the specific requirements in order to improve fault tolerance of the sensor network. However, this high redundancy of sensor nodes can lead to excessive energy wastage. Since the nodes have limited energy resources and each sensor node requires a specific amount of energy to monitor a target, judicious energy management becomes an important concern of the Target Coverage Problem. In this paper we propose a protocol for Target Coverage Management with the aim to minimize consumption of energy.

Title:	NONLINEAR MPPT CONTROL OF SQUIRREL CAGE INDUCTION GENERATOR-WIND TURBINE
Author:	M. BENCHAGRA, M. MAAROUFI. M. OUASSAID
Source:	Journal of Theoretical and Applied Information Technology pp 026 - 033 Vol 35. No. 1 -- 2012
Abstract	This paper presents a nonlinear control method to track the maximum power point of wind turbine equipped with Squirrel Cage Induction Generator (SCIG). Since the mechanical power of wind turbine is function of its shaft speed at a given wind velocity, the proposed controller provides the desired voltage at the output of Voltage Source Converter (VSC) so as to control the generator speed and then extracting maximum power from wind. The controllers exploit the backstepping scheme to calculate the required converter’s control to eliminate the instantaneous errors of mechanical speed and flux. The proposed control laws are derived from the Lyapunov approach which is well suited for this nonlinear system. Finally, the simulation results verify the stability and effectiveness of the control strategy proposed.

Abstract	The end-of-course grades assigned by lecturers are intended to convey the level of achievement of each student in the class. These grades are used to make a multitude of decisions. Unless a sufficiently accurate and efficient method is used for the grading, the grades are apt to convey misinformation and lead the decision-maker astray. In itself, the processing of results is found to be rather tedious, especially when carried out manually, and when the number of students is large. It is time-consuming and error prone. The process, however, becomes a lot easier and much more accurate when carried out with a computer running a suitable software application. To find a sufficiently fast and accurate method of carrying out this processing is a problem that is both challenging and interesting. In this work, a computer software application was developed to facilitate the automated processing of the results. The software was developed in Java programming language in the form of a database, employing MYSQL Relational Database Management System. The developed software performed well and produced expected results on completion. With it, it was possible to compute Grade Point Average and Cumulative Grade Point Average for each student based on examination scores entered.

Abstract	A flexible and versatile solution to voltage quality problems is offered by active power filters. Currently they are based on PWM converters and used to connect to low and medium voltage distribution system in shunt or in series. Active power filters can perform one or more of the functions required to compensate power systems in improving power quality. Hybrid Filter, which is a combination ofan active series filter and passive shunt filter is quite popular because the solid-state devices used in the active series part can be of reduced size and cost (about 5% of the load size) and the major part of the hybrid filter is made of the passive shunt L-C filter used to eliminate lower order harmonics. It has the capability of reducing voltage and current harmonics at a reasonable cost. To provide high power quality at the Point of Common Coupling (PCC) of power distribution systems, elimination of the harmonics is indispensably necessary. The power quality and allowable Harmonic levels in power system are defined by International standards (like IEEE-519-1992, IEC-61000). Hence, it is invariably necessary to design filters meeting the said International standards. Harmonics in hybrid filters can be reduced by using multilevel inverter. A seven level cascaded multilevel is used in the present work to mitigate the harmonics in Hybrid filter. The simulation results of the same are presented in this paper for a distribution system of voltage 11KV.

Abstract	The omnipresence of the computer system tools intensified every year in all companies. They integrate equipments, data and services that constitute a wealth to protect. Lot of mechanisms have been developed to assure the computer systems security. Conventional intrusions detection systems “IDS” have shown their insufficiencies and limits. To improve computer systems security approach, in our previous articles, we have proposed an exact algorithm for the deployment of security policies for single computer systems [1] and an enhanced three levels security policy for complex computer systems [2], However, manual analysis of the huge volume of data generated, audit data, is usually impractical. To overcome this problem and evaluate our system proposed in [2], we use Support Vector Machines (SVM) which becomes one of the most important techniques for anomaly intrusion detection due to their good generalization nature and the ability to overcome the curse of dimensionality [3, 4] with applications involve large number of events as well as large number of features. Experimental analysis and comparison shows that our proposed system in [2] outperformed other recent systems [5, 6] in precision, computation time, false positive and false negative rate.

Abstract	Effectiveness and accurate results from an algorithm has always been a basic reference for every step taken in the use and utilization of algorithm, which is expected to achieve optimal results both in quality and quantity. In order to realize the level of accuracy and effectiveness from the program, it would require an algorithm that can minimize error and faster in data processing rate compared with existing algorithm In this paper, we have compared two algorithms, namely Affinity Propagation and K-Means, at data student based on GPA and Duration of Bachelor-Thesis Completion. The results show that Affinity propagation gives the result of data cluster more accurate and effective than K-Means, it can be seen from the testing table which showing that the value of affinity propagation exemplar has not changed at all after five trials. While K-Means, gives values of its centroid are different after five trials. And at the data students itself, it show that there is a relationship between GPA and Duration of Bachelor-Thesis completion in Gunadarma University students, it can be seen from the results of data clustering, that is for student who have GPA above 3 to 4 have a tendency to finish their Bachelor-Thesis faster, which is less than 1 until 2 semesters. While other students who have GPA less than 3 have a longer time to finish their Bachelor-Thesis, within a period of 2 until more than 4 semesters.

Abstract	The success of mobile communication, shows that the interest in users to access the Internet or their official networks on the move. This mobility support may be needed for a single user or group of nodes called as movable sub networks. Network Mobility (NEMO) protocol developed by IETF enables the mobile nodes and networks to maintain connectivity to their network or Internet by change their point of attachment to from one access network to another. NEMO is an extension of Mobile IPv6, this works based on tunneling the data from home agent to mobile router. The Quality of Service provided by the NEMO is measured based on the routing mechanism it operates, hand off latency and the way of secured data transfer. Though the tunneling process ensures the security of data, the various nodes involved in NEMO are vulnerable as the network is wireless without a proper infrastructure. This article presents a survey on possible threats and solutions for NEMO protocol and its extensions.

Abstract	Distributed generation (DG) systems have attracted increased interest due to ever increasing energy consumption, rising public awareness of environmental protection, and steady progress in power deregulation. Different renewable energy sources in the distribution system are integrated through an AC bus. Dynamic models for the main system components, namely, wind energy conversion system (WECS), PV energy conversion system (PVECS), fuel cell, electrolyzer, power electronic interfacing circuits, battery, hydrogen storage tank, gas compressor and gas pressure regulator, are developed earlier. Based on the dynamic component models, a simulation model for the proposed hybrid energy system has been developed using HOMER (Hybrid Optimisation Model for Electric Renewables). The overall energy management strategy for coordinating the power flows among the different energy sources is presented with cost-effective approach.

Author:	CHUNWEI CHEN
Source:	Journal of Theoretical and Applied Information Technology pp 092 - 099 Vol 35. No. 1 -- 2012
Abstract	The purpose of this study is to test the feasibility of applying an interpretive structural modeling (ISM) method for case hosts to develop verity design solution of case host preference-based products. In the early design concept stage of the product development, designers often need to create many ideas as the case of products for the main idea of what case the host wants. Hence, a conversion approach that can provide multiple design solutions meet case host’s requirements is needed. This study presents an ISM method for developing verity design solution of case host preference-based products. A razor will be used as the test case. The experimental results from this study provide product designers with a new design approach for developing verity design solution of case host preference-based product.

Author:	SITI NURMAINI
Source:	Journal of Theoretical and Applied Information Technology pp 100 - 111 Vol 35. No. 1 -- 2012
Abstract	This paper presents new hybrid control architecture-based interval type-2 nuro-fuzzy (IT2NF) for embedded mobile robot navigation where event-driven control is used to handle the dynamically changing of the environment. The proposed hybrid control architecture combining behavior-based reactive navigation and model-based environmental classification has been developed. Weightless neural network (WNNs) in charge of environmental classification, this strategy does not only enable the mobile robot to avoid local minimum points but also eliminates the requirement for prior detailed modeling of the environment. Then, IT2FLC based reactive behavior is utilized to perform mobile robot navigation task use environmental pattern classification. The previous study show that embedded controller on low cost microcontroller is difficult to design due to hardware and software constraints. In this paper, the hybrid control architecture uses hierarchical structure of IT2 fuzzy sets (IT2FS) to avoid the huge rule base due to the embedded platform and modular structure of WNNs to reduce the computational cost and increases processing speed of the controller. Technologies to address these limitations are integrated into hybrid controller architecture to be carried out, thus the autonomous mobile robot navigation system can be executed successfully. Flexibility and performance of the proposed control architecture is validated through experiments on the real embedded mobile robot in a variety of environmental condition. The experimental results show that, the proposed architecture-based IT2NF has dealt in real environment with uncertainties present in the changing and unstructured environments can avoid obstacles at the desired safe distance, follow the desired trajectory in smooth movement and produces minimal computational resources.
