Title:	SEMANTIC WEB SECURITY AND PRIVACY
Author:	N K PRASANNA ANJANEYULU ANNA, SHAIK NAZEER
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 1 -- 2010
Abstract	The Semantic Web aims at enabling sophisticated and autonomic machine to machine interactions without human intervention, by providing machines not only with data but also with its meaning (semantics). In the Semantic Web, any two strangers can interact with each other automatically and therefore this assumption does not hold. In this setting, traditional security mechanisms are not suitable anymore. Hence, a semantically enriched process is required in order to regulate an automatic access to sensitive information. Policy-based access control provides sophisticated means in order to support protecting sensitive resources and information disclosure. This paper provides an introduction to policy-based security and privacy protection, by analyzing several existing policy languages. Furthermore, it shows how these languages can be used in a number of Semantic Web scenarios.

Title:	APPLICATION OF STRUCTURED QUEUING NETWORKS IN QOS ESTIMITION OF TELECOMMUNICATION SERVICE
Author:	YAROSLAVTSEV A.F., 2Al-THUNEIBAT S.A., 3 AL TAWALBEH N.A
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 1 -- 2010
Abstract	We present the structured queuing network as effective mathematical model of telecommunication sys-tem; this model is oriented on the analysis of delay in telecommunication networks. A set of special com-ponents are identified for providing structurization of such models. QoS parameters: the average delivery time and the utilization coefficient are calculated for MPEG video LAN implementing structured queuing model. In this paper, we propose the use of structured queuing networks to model high speed communication networks, which is more adequate than conventional analytical models, and expends less computational time than simulation models.

Title:	A NOVEL ULTRA WIDE BAND YAGI MICROSTRIP ANTENNA FOR WIRELESS APPLICATIONS
Author:	MAMDOUH GOUDA 2MOHAMMED Y. M. YOUSEF
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 1 -- 2010
Abstract	This paper presents an Ultra Wide Band Microstrip Yagi antenna with very good performance at four main operating frequencies (0.85, 2.4, 3.5 and 5.2) GHz. Numerical simulation results of our design show more than (-20 to -40) dB return loss at the bands of (0.85, 2.4, 3.5, 4.5 and 5.2) GHz and VSWR less than 1.7 at these frequencies. The simulation method based on finite element method (FEM) was applied by using HFSS simulator to obtain the optimized parameters in order to find the best design for this antenna. The antenna bands can be varied to be suitable for various wireless applications. Finally a fabrication to the final design has been implemented, and then a measurement performed to compare the actual results with those simulated. Measured return loss and VSWR of this antenna are presented to validate the results of simulation so that it give (0.85, 2.4, 2.75, 3.6, 4.2 and 5.3) GHz for the measured return loss results and the antenna VSWR ≤ 1.5 at (2.4, 3.5, 4.5 and 5.2) GHz.

Title:	A DECENTRALIZED COALITION FORMATION ALGORITHM AMONG HOMOGENEOUS AGENTS
Author:	LEILA KHALOUZADEH, DR.NASER NEMATBAKHSH, DR.KAMRAN ZAMANIFAR
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 1 -- 2010
Abstract	In a multi-agent environment, the accomplishment of a task may necessitate the co-operation of a number of agents. In order to allocate a task to a group of agents, methods of coalition formation in multi-agent systems can be used. In multi-agents systems, the formation of an optimal coalition is one of the main challenges to be overcome. With increase in the number of agents, the number of possible coalitions potentially capable of carrying out a specific task increases exponentially. Determining the value of each potential coalition in order to choose the best option involves an excess of time and memory usage. Some algorithms have solved the problem by distributing the calculation among the agents. Considering the fact that the agents are mobile the distance between the agents and the task is significant and that certain capabilities are required for any one task to be carried out we have presented a new algorithm for coalition formation. Here, the optimal coalition is determined without having had to ascertain the value of each potential coalition beforehand. Another advantage of this new algorithm is that there is no need for any connection between agents in the coalition formation stage. Moreover, the result of simulation and comparison show that this novel algorithm saves agents transfer time and cost.

Abstract	VNR Vignana Jyothi Institute of Engineering and Technology- have an existing network of outdated equipment purchased on an as-needed basis with limited planning and support. A portion of the outdated equipment was reaching end-of-life (EOL). The network was unmanaged & a lot of its equipment was outdated and underperforming, however, the college�s rapid growth and subsequent increase in network traffic, was creating a demand for more network applications and updated hardware. Before deploying a wireless network, it needed to update its network to boost bandwidth capacity and resiliency and tighten security controls. In addition to supporting its communications and applications. The college�s vision was to build a facility that provided the students, faculty and staff with the most up-to-date IP network that would enable secure delivery of data over Wired as well as Wireless Network.

Title:	INFORMATION EXTRACTION AND AD HOC ANAPHORA ANALYSIS
Author:	A.SURESH BABU, DR P.PREMCHAND, DR A.GOVARDHAN
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 1 -- 2010
Abstract	Anaphora is the prominent linguistic element that defines the contextual coreference. It is very essential to apprehend and reason out large texts for the discovery of summary and forms of knowledge. Methods and Techniques are available for specific contextual elements that frame out as summaries and forms of knowledge. Important information which have keen actionability is sometimes not possible to extract using methods and techniques that are approved from available research. And, this is a task which shall be requisite for text detection and extraction to find out reasonable inferences from a huge corpus of non domain texts. We propose Ad Hoc Anaphora Analysis as the novel method introduced in this work to structure and build the framework that implement for a large non domain text corpus.
Keywords	Linguistic Analysis, Coreference, Anaphora, Ad Hoc Modeling, Uncertainty Models.

Author:	QADEEM KHAN1, SHAHBAZ GHAYYUR
Source:	Journal of Theoretical and Applied Information Technology Vol 22. No. 1 -- 2010
Abstract	The Global Software Development is becoming so much complex and challengeable as the scope of the problem domain of the user increases day by day advancement. In today�s modern world of engineering development, almost all projects suffer from some unwanted threats called risks which can seriously affect the quality, cost and schedule of the projects and hence could have a large negative impact on a project. Even many projects are cancelled due to catastrophic risks so it is very much important for a good project management to identify, monitor, plan and control the potential risks so that it is ensured that the project completes according to the satisfaction of all stakeholders interested in the project. The risks occur in GSD are much more different than those risks that in Local Software Development. Even sometime a tinny risk becomes a serious catastrophic risk in GSD. This paper provides some necessary information regarding the potential risks that can occur in the GSD, their consequences on the projects, and some useful guidelines of handling these risks.
