Testing is a very important task to build error free software. As the resources and time to market is limited for a software product, it is impossible to perform exhaustive test i.e., to test all combinations of input data. To reduce the number of test cases in an acceptable level, it is preferable to use higher interaction level (t way, where t = 2). Pairwise (2- way or t = 2) interaction can find most of the software faults. This paper proposes a matrix based calculation for pairwise test data generation algorithm named EasyA to optimize the number of test cases. Java program has been used to test the performance of the algorithm. The performance is better than the existing algorithms/tools in terms of number of generated test cases and time consumption.

The availability of high quality and inexpensive video camera, as well as the increasing need for automated video analysis is leading towards a great deal of interest in numerous applications. However the video tracking systems is still having many open problems. Thus, some of research activities in a video tracking system are still being explored. Generally, most of the researchers are used a static camera in order to track an object motion. However, the use of a static camera system for detecting and tracking the motion of an object is only capable for capturing a limited view. Therefore, to overcome the above mentioned problem in a large view space, researcher may use several cameras to capture images. Thus, the cost will increases with the number of cameras. To overcome the cost increment a mobile camera is employed with the ability to track the wide field of view in an environment. Conversely, mobile camera technologies for tracking applications have faced several problems; simultaneous motion (when an object and camera are concurrently movable), distinguishing objects in occlusion, and dynamic changes in the background during data capture. In this study we propose a new method of Global best Local Neighborhood Oriented Particle Swarm Optimization (GbLN-PSO) to address these problems. The advantages of tracking using GbLN-PSO are demonstrated in experiments for intelligent human and vehicle tracking systems in comparison to a conventional method. The comparative study of the method is provided to evaluate its capabilities at the end of this paper.

Nowadays, the using of intelligent data mining approaches to predict intrusion in local area networks has been increasing rapidly. In this paper, an improved approach for Intrusion Detection System (IDS) based on combining data mining and expert system is presented and implemented in WEKA. The taxonomy consists of a classification of the detection principle as well as certain WEKA aspects of the intrusion detection system such as open-source data mining. The combining methods may give better performance of IDS systems, and make the detection more effective. The result of the evaluation of the new design produced a better result in terms of detection efficiency and false alarm rate from the existing problems. This presents useful information in intrusion detection.

This paper presents a new way of online communications through mobile to web that helps students and lecturers to be always aware of appointments no matter where they are. It contributes to the teaching and learning process, in which communication is made easy using short messaging system (SMS) technology which is called Web-based Student Appointment System with GSM Network (WASGN). It starts with examples of previous success stories of the implementation of SMS in many areas. The objectives of the paper are to discuss about the hardware and software requirement, and integrate them to be measured in terms of functionality. The research method is outlined next, and some discussions over current outcomes of the research are addressed. The prototype of WAS-GN is successfully implemented using SMS technology. Briefly, results show that WAS-GN is able to solve the appointment-making problem.

Service-oriented architectures (SOA) can be considered as an enabling methodology for Cloud Computing and the IT's industrialization, standardization and commodity approach. The efforts to effectively introduce SOA were driven by the evermore increasing complexity and volume of information to be consumed. This paper discusses in this context some major quality characteristics of SOA systems and new measurement approaches, considering complex IT systems and digital ecosystems. This approach is based on growth models related to SOA's reference architecture as well as diversity and entropy. On a field test certain metrics are applied to a real large scale SOA system. As a result some major and important characteristics of the SOA system can be proven and weak structures in services orchestrations exposed.

In this paper we propose a method for using ethnographic field data to substantiate agent-based models for socially-oriented systems. We use the agent paradigm because the ability to represent organisations, individuals, and interactions is ideal for modelling socio-technical systems. We present the results of in-situ use of a domestic application created to encourage engagement between grandparents and grandchildren separated by distance. In such domains, it is essential to consider abstract and complex quality requirements such as showing presence and sharing fun. The success of such domestic technologies is based on the meaningful realisation of these difficult-to-define quality goals. Our method addresses the need to adequately inform these quality goals with field data. We substantiate the quality goals with field data collected by introducing an application into the home of three families. The field data adds an understanding of what sharing fun means when "filled" with concrete activities. The quality goals served as a template to explore and represent the rich field data, while the field data helped to formulate the requirements for a more complex and refined technology. This paper's contribution is twofold. First, we extend the understanding of agent-oriented concepts by applying them to household interactions. Second, we make a methodological contribution by establishing a new method for informing quality goals with field data.

Current research efforts are being directed to commit with the long-term view of self-management properties for wireless telecommunications. Technology has transformed the cell phone from being a mere phone to becoming an indispensable medium for contact, information and entertainment. The new paradigm in mobile services lies in providing a location-based user experience and here lies the tremendous scope for expansion of location-based services (LBS). One of the key approaches that have been recognized as an enabler of such a view is policy-based management, which has been mostly acknowledged as a methodology that provides adaptability and support to automatically assign network resources, control Quality of Service and security, by considering administratively specified rules. The hype of policy-based management was to commit with these features in run-time as a result of changeable network conditions resulting from the interactions of users, applications and existing resources. This paper proposes an adaptive architectural framework which deals with the critical nature of addressing the policy conflict problem. In this framework, policies are used as a mechanism to direct and adapt the behavior of self-adaptive systems. This policy-based framework consists of a set of processes, the self-coordinator process represents as the main process; which coordinates all the framework activities. Furthermore, the paper provides a guideline to avoid static and dynamic policy conflicts of different applications.

Among various available numerical solution techniques, finite element method (FEM) is one of the important methods of those. Usually elements are sub-divided uniformly in FEM which is known as conventional FEM (CFEM) to obtain temperature distribution behavior in a fin or plate for various aerospace and mechanical engineering applications. Hence, extra computational complexity is needed to obtain a fair solution with required accuracy. In this paper, an algorithm is proposed to generate non-uniform sub-elements and then implemented on FEM to obtain optimum FEM (OFEM) solution to reduce the computational complexity. This OFEM is applied for the solution of two-dimensional heat transfer problem in an insulated-tip thin rectangular fin. The obtained results are compared with CFEM. It is found that the OFEM exhibit around 65% more accurate results than CFEM showing its potentiality.
