Essam Al-Daoud. Computer Science Department, Zarka University, Jordan. Abstract- In this study, a modified fuzzy c-means radial basis functions network is proposed. The main purposes of the suggested model are to diagnose the cancer diseases by using fuzzy rules with relatively small number of linguistic labels, reduce the similarity of the membership functions and preserve the meaning of the linguistic labels. The modified model is implemented and compared with adaptive neuro- fuzzy inference system (ANFIS). The both models are applied on "Wisconsin Breast Cancer" data set. Three rules are needed to obtain the classification rate 97% by using the modified model (3 out of 114 is classified wrongly). On the contrary, more rules are needed to get the same accuracy by using ANFIS. Moreover, the results indicate that the new model is more accurate than the state-of-art prediction methods. The suggested neuro-fuzzy inference system can be re-applied to many applications such as data approximation, human behavior representation, forecasting urban water demand and identifying DNA splice sites.   Keywords- fuzzy c-means; radial basis functions; fuzzy-neuro; rules; cancer diagnosis. 2- Geometric Transformation Technique for Total Hip Implant in Digital Medical Images, Download pdf.

Said Ghoniemy, Ashraf Fahmy, Sultan Aljahdali. College of Computers and Information Systems,Taif University, Saudi Arabia.   Abstract- The fields of Learning Management Systems (LMS) and Learning Content Management Systems (LCMS) are full of open source and commercial products including Blackboard, WEB CT, and Moodle. These systems are tutor-oriented, not designed to facilitate personalized learning support for an individual learner. Professors and students, frustrated with current LMS, need a new, innovative, user-friendly alternative to encourage and empower students to take control of their education, and teachers to explore new styles of teaching, depending on their students’ needs. Most of the students in the developing world, specially in the middle east region, suffer from limited English proficiency, in addition to limited computer skills. These obstacles compose a barrier to, and impose limitations on the design and implementation of E-learning systems. This paper introduces a prototype for a simple, dedicated, learner-oriented e-learning system to facilitate the learning process. The proposed system enables the student (even with moderate English level and general IT knowledge) to wander through the system, and register for a specific course to make use of the scientific material available there in. In addition, the design of a computer engineering course conforming SCORM standards is introduced. The proposed prototype is made available for students to examine and evaluate. Feedbacks will be analyzed and enhancements will be proposed.   Keywords- component; e-learning; Learning Management Systems; Content Management Systems; Virtual University.   4- Adaptive System Simulation and Noise Analysis Toolbox (ASSNAT) : The Open-Source Toolbox Developed with Newer Features for Adaptive System Simulation, Download pdf.

Ibrahim Electronics & Communication Eng. Dept, Ain Shams University, Cairo, Egypt.   Abstract- Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management, and data dissemination protocols have been specially designed for WSNs. The focus has been given to the routing protocols which might differ depending on the application and network architecture. In this paper, we propose an energy efficient data forwarding protocol called Energy Aware Geographic Routing Protocol (EAGRP) for wireless sensor networks to extend the life time of the network. In EAGRP, both position information and energy are available at nodes used to route packets from sources to destination. This will prolong the lifetime of the sensor nodes; hence the network life time and thus get higher packet delivery ratio and minimal compromise of energy efficiency. The proposed protocol is an efficient and energy conservative routing technique for multi-hop wireless sensor networks. The routing design of EAGRP is based on two parameters: location and energy levels of nodes. Each node knows the location and energy level of its neighbors. The performance measures have been analyzed with variable number of nodes. Our simulation results indicate that the proposed algorithm gives better performance in terms of higher packet delivery ratio, delay, and energy consumption. Keywords- Wireless Sensor Networks; Energy efficient; Position information; Routing protocol.   7- A Novel Business Intelligence System Framework, Download pdf. Hanumat G.

M. Viju Prakash, Department of Computer Science & Engineering, Sardar Raja College of Engineering. P. Alwin Infant, Department of Computer Science & Engineering, Sardar Raja College of Engineering. S. Jeya Shobana, Department of Computer Science and engineering, Francis Xavier engineering College.   Abstract- Secure network partially depends on user authentication and unfortunately authentication schemes used at present are not utterly secure. Some passwords are not computationally dominant, where brute force attacks on this unprecedented scale became potential. Here we have designed a combined schema of One Time Password (OTP) algorithm concatenated with PassText which makes uncomplicated to commit to memory and is computationally powerful. It can be fairly and rapidly provided to the system, while at the same time remaining impractical to break the brute force attack. OTP algorithm powered with user’s unique identifications like International Mobile Equipment Identification and Subscriber Identification Module; makes a finite alphanumeric token valid for a session and for a single use. PassText is an easy way of system authentication schema which enables the user not obligatory to memorize any difficult passwords or character combinations. Concatenation of these two schemas gives maximum security for authentications and almost impossible to break. We have also proposed a novel measure of security levels of many popular authentication schemas against the one we proposed.   Keywords- Brute force, OTP, PassText, Token, Security.
