Title	DETECTING ARABIC SPAM WEB PAGES USING CONTENT ANALYSIS
Authors	RADWAN JARAMH, TALAL SALEH, SHERIF KHATTAB, IBRAHIM FARAG
Abstract	In this paper, we propose a set of new features to enhance the classification of Arabic Web pages into spam and non-spam under different classification algorithms, namely Decision Tree, Naїve Bayes, and LogitBoost. We compare our features, which we call Arabic Content Analysis (ACA) features, to state-of-the-art Content Analysis (CA) features for spam detection in the English Web. We show that augmenting the CA features with our ACA features achieves an increase in detection accuracy of Arabic spam pages compared to CA features alone. When combined, ACA and CA features correctly identified 5,536 pages of the 5,645 Arabic spam pages that we used for testing with a false positive rate of 1.9% using the Decision Tree classifier. We also identified the top-ranked features using the Gain Ratio method.

Title	FUZZY EXTREME LEARNING MACHINE ALGORITHM FOR MATRIX CONVERTER
Authors	VENUGOPAL CHITRA, K.S.RAVICHANDRAN, R.VARADARAJAN
Abstract	This paper is focused on Fuzzy Extreme Learning Machine (ELM) algorithm based field oriented control system for induction motor fed by Matrix Converter drive. The use of fuzzy ELM algorithm based ANN Controllers in the FOC system reduces the computation time. The controller is used to compute the appropriate set of switching voltage vectors for matrix converter to achieve the maximum efficiency for any value of operating torque and motor speed. In this paper, the Matrix Converter with field oriented control system is designed using MATLAB/SIMULINK toolbox. Initially, fuzzy logic controllers are used as current and torque controllers. ELM controller is designed to replace space vector modulation circuit in the conventional field oriented control system. The three inputs to the Fuzzy ELM controller are Va, Vb and Vc* and the outputs of the ELM controller are voltage vectors for appropriate switching of matrix converter. The performance of the induction motor is tested for various reference speed and torque values. The speed and torque curves of the induction motor shows that the use of ELM controller reduces the ripples in torque and reduces the response time in the speed curve due to the fast response time of the ELM Controller

Title	CERTIFICATION IN ELECTRONIC PAYMENT GATEWAY
Authors	NOSHEELA RAZIQ, AIHAB KHAN, M.SIKANDAR HAYAT KHAYAL
Abstract	In this paper main aim is on security problems related to electronic payment gateway. This paper addresses the requirement of certification of users and merchants during the process of online transactions. Security of electronic payments is quite a big issue now a days and there is need of secure transaction process. Authentication of merchant or customer is quite important and certification is a process through which we can first authenticate the customer and merchant and any other parties that are involved in the payment, then payment can be done. On the basis of these requirements, we proposed a system which will provide the facility of providing the certificates to authorities. Experimental results show that cost consumption of database values is directly proportional to the size of database. Memory consumption is also directly proportional to the size of the database. From results it is concluded that efficiency of system depends on values that are stored in database.

Title	ANALYSIS OF COGNITIVE COMPLEX LOAD FACTOR ON VISUAL AID BASED COMPUTER PROGRAMMING LANGUAGE LEARNING
Authors	MUHAMMED YOUSOOF, MOHD SAPIYAN
Abstract	Computer applications are dominant and have become part of day to activities of the human life. These applications are developed by the software developers based on their expertise in domain knowledge and the skills of computer languages. Most of this knowledge of programming has developed from the educational system mainly while learning the computer programming languages at the tertiary educational level such as college education. In general the students are interested and motivated to learn the computer language if provided with effective and user friendly learning tools. The basic fact is that all individuals are different and so their learning capacity differs from one another based on their cognitive ability. This paper addresses the cognitive factors that have the impact during the learning processes and the measurement of cognitive load while the students learn using different computing languages with different tools

Title	CONFIDENTIALITY OF MESSAGES IN A CARDLESS ELECTRONIC PAYMENT SYSTEM
Authors	MISBHA IRUM, AIHAB KHAN, MALIK SIKANDER HAYAT KHIYAL
Abstract	In a cardless electronic payment system messages are used instead of credit or debit cards (plastic money). These messages are passed between different entities in order to do electronic transactions over a network. The security of the cardless electronic payment system is a critical issue. In case of security breaches huge financial damages can be occur. This paper describes the work aiming at the security of a card less payment system. The confidentiality of messages in card less payment system is done. The messages passed between different entities are secured by using hybrid encryption and decryption technique. The Analysis of different pair of encryption/decryption algorithms which are RSA-DES, RSA-AES and RSA-TRPLEDES in the hybrid encryption technique is done and conclusions are drawn on the basis of execution time and memory usage. Experimental results show that RSA-DES executes faster and takes less memory so it is most suitable for hybrid encryption/decryption of messages.

Title	ARTIFICIAL NEURAL NETWORK BASED DIRECT TORQUE CONTROL SYSTEM FOR SELECTING SWITCHING VECTORS IN MATRIX COVERTER DRIVE SYSTEM
Authors	VENUGOPAL CHITRA, K.S.RAVICHANDRAN, R.VARADARAJAN
Abstract	This paper presents Artificial Neural Network (ANN) based Direct Torque control scheme for Matrix Converter fed Induction Motor. Matrix Converter drives have received more attention due to its bidirectional current flow, sinusoidal input current, sinusoidal output voltage and adjustable displacement angle. Direct Torque Control scheme provides direct control of motor torque and flux and hence provides fast torque response and flux control. The DTC technique has the drawback of torque and flux ripple. The drawbacks of DTC technique has been addressed some extent by Fuzzy Logic. The accuracy may be increased by using fuzzy logic, but at the same time it can be used only a static environment. In case of dynamic decision-making, the artificial neural network is used. In this paper, the optimisation of the neural network using fuzzy inputs to estimate the reference voltage vectors using various combinations of flux position, stator flux and torque values is done. Then the ANN controller replaces space vector modulator which generates the appropriate switching states for Matrix Converter. The Lavenberg-Marquardt back propagation technique has been used to train the neural network. The simulation model of the proposed scheme is presented. The speed and torque response of the model is presented for various switching frequencies.
