Abstract — The objective of this work is to establish an information system which would facilitate decision making for the exploitation of a model consisting of the main university stakeholders (teachers, students and administrators). This system is based on the relationship between actors (players) on the one hand and their activities and their aggregations in a graduate level on the other. It aims to make available to managers of the university a set of dashboards that can improve the quality of education. Meanwhile, ontology is now at the heart of the work of engineering knowledge and demonstrated in several areas. An ontology dedicated to the design of SD is a model of organization of knowledge for a given domain. It represents the multidimensional concepts of a domain and their multidimensional relationship (LDR) and semantic. After recalling our ontology construction method decision, we will detail in this paper the optimization phase of RMD after the enrichment of the ontology. This phase is governed by rules that we define optimization.

Abstract — Taking advantage of today’s hyper connected world, many institutions of higher education have already implemented online education programs, while many others are currently investigating online education models for use in the near future. As colleges and universities gradually explore the feasibility of including distance education programs, privacy protection and securing computer networks remains a primary concern for them. Privacy concerns when using online education models increase as most of the communication among students, faculty, and administration occurs electronically. This paper analyzes privacy policies in three institutions that represent different education models: established face-to-face, established online and prospective online models. The paper addresses privacy laws related to institutions of higher education in general and offers recommendations for those institutions of higher education that are considering expanding their face-to-face offerings to include online education models.

Abstract — In recent years, the various processes and with different aspects were created in order to response the needs of producing secure software. As a result of secure methodologies production to develop software, their evaluation is difficult to select a methodology for a specific project. Due to This need, a framework for evaluation and measurement methodology plays an important role. Evaluation must consider the various parameters of the software project and pay attention to the similarities, differences, features and application of available methodologies. So there is need for measures to cover these requirements. Despite the researches in the analysis and evaluation of secure methodologies for software production in various aspects, the lack of an overall framework for evaluating these methodologies is seen. In this paper, we offer an extended framework for evaluating the secure methodologies that cover different aspects of a software development methodology. This framework will be considered the needs of project managers and method engineers in order to choosing an appropriate secure methodology in the desired project.

Abstract - One of the most challenging in eXtreme Programming is composing the entire team member and customer onsite. This problem will become seriously when the entire team member unavailable in the same place or the customer cannot give representation person for the development team. This situation will make information imperfectly for both customer and team member. In this research, we solve the problem by implementing computer support cooperative work (CSCW) as a tool to improve eXtreme Programming method. By joining these two concepts, we get 15% productivity improvement as a ratio between XP projects with CSCW and without CSCW.

Abstract — Most signature−based antivirus products are effective to detect known malwares but not unknown malwares or malwares' variants, which make them often lag behind malwares. Also most antivirus approaches are complex for two reasons. First, lots of malicious and benign codes as training dataset are difficult to collect. Second, they would consume lots of times when training classifiers. Immunity PE Malware Detection System (IPEMDS) was designed to give computer systems PE homeostatic capabilities analogous to those of the human immune system. Because the constraints of living and computational systems are very different, however, we cannot create a useful computer security mechanism by merely imitating biology. IPEMDS approach has been first to choose a set of requirements similar to those of the immune system. It then created abstractions that captured some of the important characteristics of biological homeostatic systems and then used these abstractions to guide the design of two levels of defense called them IPEMDS. The goals of IPEMDS are to obtain high detection rate and a very low false positive. IPEMDS enter in a challenge to a chief this goal from depending only on a finite numbers of benign files to classify between a new benign and malware executable files, and both of them unseen before by IPEMDS.

Abstract - Image Compression is just used everywhere. All the images you get on the Internet and web pages are compressed, typically in the JPEG or GIF formats, most modems use compression, HDTV will be compressed using MPEG-2 and several file systems automatically compress files when stored and the rest of us do it by hand. Compression is that the algorithms used in the real world make heavy use of a wide set of algorithmic tools, hash tables, including sorting, dictionary and FFTs. Furthermore, algorithms with strong theoretical foundations and implementation play a critical role in real-time applications because many of compression algorithmic models available, where in some of the algorithms will only be standing in the field. In this paper we are concentrating about zero tree wavelet method and proposed an enhancing approach in zero tree wavelet method.

Abstract - This research work is motivated by the need to achieve low latency in an input-queued centrally-scheduled cell switch for high-performance computing applications; specifically, the aim is to reduce the latency incurred between a request and response arrival of the corresponding grant. The minimum latency in switches with centralized scheduling comprises two components, namely, the control-path latency and the data-path latency, which in a practical high-capacity, distributed switch implementation can be far greater than the cell duration. We introduce a speculative transmission scheme to significantly reduce the average control-path latency by allowing cells to proceed without waiting for a grant, under certain conditions. It operates in conjunction with any centralized matching algorithm to achieve a high maximum utilization. Using this model, performance measures such as the mean delay and the rate of successful speculative transmissions are derived.

Abstract - An ad hoc wireless network consists of set of mobile nodes connected without any central administration. Path finding processes in on-demand route discovery methods in mobile ad hoc networks (MANETs) use flooding. Source mobile node simply broadcast route request (RREQ) packet to its neighbor node and once again the neighbour node rebroadcast RREQ to its neighbour until unless route to a particular destination is found. The excessive RREQ packet can lead collision problem and consume more bandwidth in the network and decrease network performance. This paper proposed new probabilistic based route discovery method to reduce number of RREQ packet generated by the mobile nodes during the path finding process. In this paper exhibits an Ad Hoc on demand distance vector Routing protocol (AODV)[1] using in simulation based on our new probabilistic method route discovery processes. When we compare the modified AODV with traditional AODV, the simulation results shows significant improvement in the terms of routing overhead and end-to-end delay.

Abstract -- In this paper, a new hybrid intelligent model comprising a cluster allocation and adaptation component is developed for solving classification and pattern recognition problems. Its computation ability has been verified through various benchmark problems and biometric applications. The proposed model consists of two components: cluster distribution and adaptation. In first module, mean patterns are distributed in to the number of clusters based on the evolutionary fuzzy clustering, which is the basis for network structure selection in next module. In second module, training & subsequent generalization is performed by the syndicate neural networks (SNN). The Number of SNNs required in the second module will be same as the number of clusters. Whereas, each network contains as many output neurons as the maximum number of members assigned to each cluster. The proposed novel fusion of evolutionary fuzzy clustering with neural network yields superior performance in classification and pattern recognition problems. Performance evaluation has been carried out over wide spectrum of benchmark problems and real life biometric recognition problems. Experimental results demonstrate the efficacy of the methodology over existing ones.

Abstract — This paper proposes an image watermarking scheme using wavelet tree quantization. The proposed approach embeds a watermark with visual recognizable patterns, such as binary or gray, in images by modifying the frequency part of the images. In the proposed approach, an original image is decomposed into wavelet coefficients. Then, image watermarking scheme based on the Simplified Significant Wavelet Tree (SSWT) is used to achieve the robustness of the watermarking. Unlike other watermarking techniques that use a single casting energy, SSWT adopts adaptive casting energy in different resolutions. The wavelet coefficients of the host image are grouped into wavelet trees and each watermark bit is embedded using trees. The trees are so quantized that they exhibit a large enough statistical difference, which will later be used for watermark extraction. Each watermark bit is embedded in all frequency bands, which renders the mark more resistant to attacks that remove certain frequency components. The performance of the proposed watermarking is robust to a variety of signal distortions, such as image cropping, adding noise, and filtering, and compression attacks.

Abstract — This paper presents a novel method for isolated English word recognition based on transform method. This isolated word recognition method consists of two phases, feature extraction phase and recognition phase. In feature extraction, discrete Fourier transform and discrete cosine transform is used for extracting the features of speech samples and feature vector of different dimensions is obtained. In Recognition phase, Euclidean distance is calculated between test sample feature vector and all reference speech samples. Speech sample with minimum average distance is selected. For testing, 30 different words are used, spoken by male and female both, 25 utterances of each word are recorded. Results are compared with different feature vector dimensions. Experimental results showed that the maximum recognition rate of 94% is obtained.

Abstract - Data Envelopment Analysis (DEA) is a nonparametrical, method for evaluating the efficiency of Decision Making Units (DMU) using mathematical programming. There are several methods for analyzing the efficiency of Decision Making Units, among which are Charnes Cooper Rodes (CCR) and Banker Charnes Cooper (BCC), which compute the efficiency of Decision Making Units using the linear programming or Wang’s method which evaluates the efficiency of Decision Making Units using Ideal Decision Making Unit (IDMU) and Anti-Ideal Decision Making Unit (ADMU) and ultimately performs the ranking of units. All these calculations occur when all data, that is the inputs and the outputs of Decision Making Units, are positive and crisp data. Now this question arises: if the data are Symmetric Triangular Fuzzy Number, how will be the method of computing the efficiency of Decision Making Units? In this article, we will introduce a method for evaluating the efficiency of Decision Making Units and also rank them using Ideal and Anti-ideal Decision-Making Units with Fuzzy Data. Finally, a numerical example is proposed to display the application of this method.

Abstract — Tracking is the process explicitly dedicated to estimate the path of the object as it moves along the region of scene in the image plane. In other words it is a strategy to detect and track moving object through a sequence of frames. Here an attempt to enable the Normalized Cross-Correlation strategy for both matching and updating the template for tracking the object in an outdoor environment is made. The proposed method explores to consume extensive bench mark dataset. The evolved system critically exhibits the capability to track an object or multiple objects genuinely under varied illumination conditions. Evidently, the outcome reveals the worthiness of the proposed developed novel system.

Abstract — The main objective of higher education is to provide quality education to students. One way to achieve highest level of quality in higher education system is by discovering knowledge for prediction regarding enrolment of students in a course. This paper presents a data mining project to generate predictive models for student retention management. Given new records of incoming students, these predictive models can produce short accurate prediction lists identifying students who tend to need the support from the student retention program most. This paper examines the quality of the predictive models generated by the machine learning algorithms. The results show that some of the machines learning algorithms are able to establish effective predictive models from the existing student retention data.

Abstract - The health care system in Nigeria is nothing to write home about, this is due to the inadequate availability of medical and human resources. This inadequacy has led to enormous paper work, waste of time, life, and ineffective treatment procedures. This study takes a look at the use of mobile technology devices such Personal Digital Assistants, cell phones, personal laptops, palm top etc for health care delivery in Nigeria. It proposes to look at how healthcare application will improve the healthcare services by providing spatially the link between patient and primary health care .This link will provide easy access to medical information at the points of health-care delivery within health care centers. An E- Health model can be designed to solve this problem, the central idea behind this model is to use web languages to describe a user’s personal health environment and extend the web browser to use this document to support user mobility. This model enables users to access user-defined health environment from anywhere, at anytime and with any kind of Internet-connected computers. With the use Unified Modeling Language, mobile, and Java-based technologies for its development, E-Health is proposed to be a general solution to the current challenges in the health sector in Nigeria.

Abstract — Many nations all over the world have increased their dependency on cyberspace by maximizing the use of Information and Communication Technology (ICT). In this digital age, the concept of cyber terrorism or the use of cyberspace to carry out terrorist activities has emerged. Interestingly, there are many concepts of cyber terrorism provided by researchers, policy makers and individuals. This paper proposes a framework describing the core components of cyber terrorism. The authors have analyzed the data by using a grounded theory approach, in which the framework is drawn. The framework defines cyber terrorism from six perspectives: Target, motivation, method of attack, domain, action by perpetrator, and impact. In addition, the proposed framework provides a dynamic way in defining cyber terrorism as well as describing its influential considerations. Continued research in this area can be further conducted, which may lead to the development of strategic and technological framework to counter cyber terrorism.

Abstract — This survey is based on the introduction, motivation, and proposed system for ecological treatment of self-organizing cooperative cognitive wireless communication. We introduced the application of related literature in the proposed wireless communication scenario. The cooperative cognitive system resembles with the symbiotic ecological model of sharing mutual resources. This philosophy is nature inspired and system evolves with autonomous mutual interaction without any centralized controller. In other words, we can say it as evolutionary game, because of the biological game being played among the analogous biological species. Therefore, an overview of related stuff for ecological modeling for CCWC is introduced as may be implementable in other engineering disciplines.

Abstract - Wireless local-area networks based on IEEE 802.11 a/b/g standards are growing rapidly. WLANs can provide the benefits of network connectivity without the restrictions of being tied to a location or restricted by wires. Despite the convenience of mobility, the performance of a WLAN must be addressed carefully before it can be adopted and deployed in any environment. In our research, we addressed the impact of various key parameters on the actual performance of IEEE 802.11g. We performed series of experiments to assess the performance of IEEE802.11g, in the presence of interferences, and finding the maximum through-put under realistic conditions. In addition the impact of co-channel, adjacent channel interferences and noises on the quality of WLAN speed was also exposed. Overall, we conducted independent set of experiments to measure the IEEE 802.11g’s effective application-level throughput. The analysis results and measurement provided insights into the required provisioning for 802.11g WLAN to ensure that it will provide the needed coverage and capacity for the intended users.

Abstract — This paper analyzes the cooperative cognitive wireless communication (CCWC) model based on biological mutualism (BM). In BM, different types of species help each other for mutual existence in the ecosystem. We tried to formulate our CCWC problem similarly like BM scenario, and examined how the bandwidth resource would be shared with each other for mutual existence, and the number of primary and secondary users which can coexist based on the available bandwidth resource.
