Title:	ELECTRONIC TOLL COLLECTION SYSTEM USING PASSIVE RFID TECHNOLOGY
Author:	KHADIJAH KAMARULAZIZI, DR.WIDAD ISMAIL
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	This paper focuses on an electronic toll collection (ETC) system using radio frequency identification (RFID) technology. Research on ETC has been around since 1992, during which RFID tags began to be widely used in vehicles to automate toll processes [1]. The proposed RFID system uses tags that are mounted on the windshields of vehicles, through which information embedded on the tags are read by RFID readers, The proposed system eliminates the need for motorists and toll authorities to manually perform ticket payments and toll fee collections, respectively. Data information are also easily exchanged between the motorists and and toll authorities, thereby enabling a more efficient toll collection by reducing traffic and eliminating possible human errors.

Title:	CALCULATION OF THE WIENER INDEX FOR SOME PARTICULAR TREES
Author:	M. EL MARRAKI, G. AL HAGRI
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	The wiener index W (G) of a connected graph G is the sum of the distances between all pairs of vertices of G. In this paper, we give theoretical results for calculating the wiener index for some composites trees (chain-trees, path-trees, etc.). In the end we give an application of its results on particular families of trees. These formulas are the part of a future attempt to demonstrate the wiener index conjecture (see introduction)

Title:	ON THE SECURITY OF FIREWALL POLICY DEPLOYMENT
Author:	A. KARTIT, M. EL MARRAKI, A. RADI, B. REGRAGUI
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	Due to the sensitive nature of information transmitted during a policy deployment, the communication between management tool and firewall should be confidential. Confidentiality can be achieved by using encrypted communication protocols such as SSH, SSL and IPSec. Much research has already addressed the specification of policies, conflict detection and optimization, but very little research is devoted to the security of policy deployment. In the previous article [1], we proposed an exact algorithm for the deployment of security policies but in this paper, we will propose an effective solution that will allow us to secure the deployment process of a political target. This solution has the objective to create secure tunnels between the different entities (firewalls)

Title:	CORRELATION COEFFICIENT MEASURE OF MULTIMODAL BRAIN IMAGE REGISTRATION USING FAST WALSH HADAMARD TRANSFORM
Author:	D. SASIKALA, R. NEELAVENI
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	A bundle of image registration procedures have been built up with enormous implication for data analysis in medicine, astrophotography, satellite imaging and little other areas. An approach to the problem of multimodality medical image registration is proposed, with a fundamental concept Correlation Coefficient, as a matching measure. It measures the statistical dependence or information redundancy between the image intensities of corresponding voxels in both images. Maximization of CC is a very broad and dominant norm. As no assumptions are made regarding the nature of this dependence and no limiting constraints are imposed on the image content of the modalities involved. The accuracy of the CC criterion is validated for rigid body registration of computed tomography (CT), and magnetic resonance (MR T1 and T2) images by comparison with the registration solution. Experimental results prove that subvoxel accuracy with the reference solution can be achieved completely automatically without any preprocessing steps that make this process ensemble for medical applications

Title:	SIMULATION: AN EFFECTIVE TOOL FOR BPR
Author:	ASHU GUPTA, PRERNA DOGRA
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	Most organizations implement business process reengineering (BPR) for improving their performances. Increasingly, companies around the world are reengineering their core business processes to be more profitable and to improve customer satisfaction. While the merits and innovative aspects of BPR are open to debate, BPR provides opportunities for management science and operations research professionals to use their skills and tools in helping shape decisions that have great implications for businesses. In exchange, these professionals can enrich BPR by contributing scientific analysis to complement the qualitative thinking currently used in the field. Investigating the business process under study and creating new process designs requires strong modeling skills and good tools. Systems engineering offers many modeling and analysis tools such as simulation, decision theory, queueing theory, optimization, utility theory, and others. The aim of this paper is to highlight the significance of Business Process Reengineering and to discuss the factors that are responsible in its successful implementation

Title:	FREQUENCY DOMAIN TECHNIQUE FOR FAULT DIAGNOSIS IN ANALOG CIRCUITS-SOFTWARE AND HARDWARE IMPLEMENTATION
Author:	V.PRASANNAMOORTHY, N. DEVARAJAN
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	In this paper, we present a fault diagnosis system for analog circuit testing based on the Simulation Before Test (SBT) approach. The circuit under test is subjected to a frequency response analysis, from which parameters are extracted such that they give unique values for every configuration of the circuit. This uniqueness makes them ideally suitable for utilization as signatures that may be used to characterize the state of the circuit. Software implementation has been done using MATLAB and SIMULINK, whereas, for the hardware implementation of the system, we have chosen the NI ELVIS platform. In both cases, signatures have been extracted from the frequency response of the circuit (Sallen-Key band pass filter). As most signature values obtained are unique, successful classification of faults is made feasible
Keywords	Circuit Under Test (CUT), Sallen-Key Band Pass Filter, Bode Plot, Peak Gain

Title:	QOS FORMAL SPECIFICATION OF ENGINEERING LANGUAGE

Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 2 -- 2010
Abstract	Distributed systems can be very large and complex and the many different considerations which influence their design can result in a substantial body of specification, which needs a structuring framework if it is to be managed successfully. The purpose of the RM-ODP is to define such a framework. The Reference Model for Open Distributed Processing (RM-ODP) provides a framework within which support of distribution, inter-working and portability can be integrated. It defines: an object model, architectural concepts and architecture for the development of ODP systems in terms of five viewpoints. Each viewpoint language defines concepts and rules for specifying ODP systems from the corresponding viewpoint. These viewpoints include an Engineering viewpoint, which focuses on the concepts for describing the infrastructure required to support selective distribution transparent interactions between objects. QoS-ODP management is now an important research topic for many universities, institutes and industrial organizations. Several approaches are being used in the ﬁeld of the formalization of QoS-ODP. The use of formal methods in the design process of ODP systems is explicitly required. An important point to take into account is the incorporation of the many proofs which have to be performed in order to be sure that the ﬁnal system will be indeed ”correct by construction”. The Event-B method is being deﬁned as a formal notation. In this paper, we explore the benefits provided by using the proof construction approach to deﬁne the protocol of negotiating QoS requirements When engineering objects in different clusters interact. In this context, we investigate the support for the specification of Quality of Service (QoS) in Event-B when modelling open distributed System in the Engineering viewpoint.

Title:	UNIVERSITY COURSE SCHEDULING USING PARALLEL MULTI-OBJECTIVE EVOLUTIONARY ALGORITHMS

Abstract	Evolutionary Algorithm (EA) provides a mechanism that can achieve efficient exploration for design spaces. Thus, it constitutes an efficient tool for identifying the best alternatives to implement the solution of a certain problem. In this work, EA is implemented to solve the university course scheduling problem and a real data from Palestine Polytechnic University (PPU) databases is used for testing. Sequential implementation of such a complex problem will suffer a long execution time to find sub-optimal solution. On the other hand, using single objective optimization model soft and hard constraints could not be well satisfied. In this work, we have implemented the EA using parallel programming techniques. This permits the execution of the program in a cluster computer to reduce the execution time. Also, many soft constraints can be considered along with the hard constraints in order to get better solutions. Results show that, after redrafting the algorithm to be multi-objective, soft cost could be reduced to the minimum when using enough individuals and iterations, at the same time, hard constraints are still satisfied. After distributing the algorithm on 7 machines with 11 processors the obtained speedup is around 6 on average and the quality of the obtained solution has improved considerably.
Keywords	Parallel Evolutionary Algorithms, Multi-objective Optimization, University Course Scheduling
