Abstract	Recently in the classification and diagnosis of cancer nodules, Gene expression profiling by micro array techniques are playing a vital role. Various researchers have proposed a number of machine learning and data mining approaches for identifying cancerous nodule using gene expression data. But, these existing techniques have certain limitations that do not handle the particular needs of gene micro array examination. Initially, micro array data is featured by a high-dimensional feature space repeatedly exceeding the sample space dimensionality by a factor of 100 or higher. Moreover, micro array data consists of a high degree of noise. Most of the conventional approaches do not adequately handle with the limitations like dimensionality and noise. Gene ranking techniques are later proposed to overcome those problems. Some of the widely used Gene ranking techniques are T-Score, ANOVA, etc. But those approaches will sometimes wrongly predict the rank when large database is used. To overcome these issues, this paper proposes an efficient feature selection technique. Wrapper feature selection approach called the GA-SVM approach is used for the effective feature selection of genes. Then, the selected features are given as input to the classifier. The classifier used in the proposed technique is Support Vector Machine (SVM). The experiment is performed on lymphoma data set and the result shows the better accuracy of classification when compared to the standard SVM with T-Score method.

Title:	A FRAMEWORK FOR EVALUATING SOA GOVERNANCE FRAMEWORKS
Author:	FAZILAT HOJAJI, MOHAMMAD REZA AYATOLLAHZADEH SHIRAZI

Abstract	While there are several SOA governance frameworks to serve SOA implementation in organizations, no systematic evaluation of these frameworks has been proposed. As a result, it is difficult to select a framework to address SOA governance requirements. Also, there are no methods for determining advantages and weaknesses of each framework. To resolve these problems, we devise a framework for evaluating and comparing SOA governance frameworks. The framework is designed to assess evaluation across the spectrum of substantive fields. It focuses on four major aspects of a SOA governance framework: concepts and properties, qualitative features, SOA governance focus areas, and pragmatics. The evaluation framework ensures that a complete picture of all aspects of SOA governance can be achieved. We demonstrate the usage of the suggested framework by evaluating Open Group framework. This evaluation identifies the strengths and the weaknesses of Open Group, and also exemplifies the capabilities of our framework.

Abstract	Social network Sites (SNS) are the major source for social capital[6], now a day’s dynamic mining [2] is a part of its activity for many organizations. Interestingly on the other end we can see that most of the users are having more than one registration on social networks [6] has been associated with two fold effects in positive and negative shades. Many young users are using these networks for adolescents [10] and for downloading free entertainment stuff, which may leads to lot of fake user registrations. Just receiving invitation to their emails, creates some of the user profiles and it then pulls the userdata of the mail account. The profile created may not be correct and this was copied [11] may lead to false or redundant information on the network domain. This became a common problem for all organizations, websites who are associated with the SNS to find many facts like number of users registered and tracking any person also sometime it may leads to ambiguity problem. As one may contain more than one profile created by her/him intentionally or unknowingly generated by anyone way specified above. Recent issues on SNS says that most of the Popular Indian film actress were defamed with fake user profiles which were created in Twitter by unknown persons and posted some morphing photos and cheap comments. These acts attracted most researchers to concentrate on providing solutions. The best feasible solution is the Centralized database, which may not be feasible for heterogeneous databases. so to overcome this we are proposing a technique in this paper known as URGA(User Registration Gateway Algorithm).

Abstract	SAHARA is a framework proposed by the authors of this paper to integrate Semantic Web and Natural Language Processing tools, to timely collect and disseminate disaster information to stakeholders to help in disaster management. This paper is related with information extraction component of SAHARA and presents a set of rules developed in GATE to extract disaster related information from online text resources. The developed pattern-action rules can be used to extract disaster entities including disaster location, type, magnitude, date and number of dead, injured, lost, homeless and affected people. A corpora is developed for various types of disasters such as earthquakes, hurricanes, floods, tsunami, forest fires, suicide bombing and military operations. The developed rule set is tested against this corpora. We achieved varying results for overall precision, recall and f-measure of extracted entities. The best results were achieved for disaster magnitude and the worst for date and time.

Source:	Journal of Theoretical and Applied Information Technology pp 143 - 146 Vol. 40. No. 2 -- 2012
Abstract	The Wireless Sensor Network (WSN) comprises of the nodes with the low power processors having very limited resources and is deployed in field to sense and analyze the data. The protocols used in the sensor network must be simple. The data collected by the node is transmitted over the sensor network is encapsulated with the IP satisfying the requirements of 6LoWPAN [3]. The computation overhead on the sensor node must be less in order to increase the life of a Sensor Node. The Simple Data Transmission (SDT) Protocol is used to encapsulate the data collected by the node. The SDT protocol has the provision of choosing the type of data to be collected by the node at various instances. The SDT protocol is developed to collect the data from the various sensors on the board to frame the data and to actuate a sensor on the board according to the requirement of the application.

Title:	ADVANCED CONTROL OF ACTIVE RECTIFIER USING SWITCH FUNCTION AND FUZZY LOGIC FOR NONLINEAR BEHAVIOUR COMPENSATION
Author:	SAIDAH, M. HERY PURNOMO, M. ASHARI
Source:	Journal of Theoretical and Applied Information Technology pp 156 - 161 Vol. 40. No. 2 -- 2012
Abstract	Power Semiconductor switches of active rectifier are characterized by highly nonlinear property, resulting in high harmonic distortion and high ripple voltage on the DC side. This paper presents advanced control using switch function and fuzzy logic for compensating nonlinear behaviour. The system applies switch function of time as the input of control strategy, instead of current and voltage in d-q frame. The fuzzy logic controller aims to minimize DC voltage deviation by regulating the line current amplitude. This system uses minimum number of sensors, which is the voltage only to avoid the effect of sensor nonlinearity to the system. This performance is demonstrated and compared with PI-optimized controller. Simulations result have been conducted for variation values of capacitance, inductance and loads. The results show that the harmonic distortion and the ripple voltage on the DC side are 0.036 % compared PI-optimized controller as 5.64 %.

Title:	CEA FRAMEWORK: A SERVICE ORIENTED ENTERPRISE ARCHITECTURE FRAMEWORK (SOEAF)
Author:	ELAHE NAJAFI, AHMAD BARAANI
Source:	Journal of Theoretical and Applied Information Technology pp 162 - 171 Vol. 40. No. 2 -- 2012
Abstract	Enterprise architecture (EA) is a new approach that organizations should practice to align their business strategic objectives with information and communication technology (ICT). Enterprise Architecture encompasses a collection of different views and aspects of the enterprise which constitute a comprehensive overview. Such an overview cannot be well-organized regardless of incorporating a logical structure called Enterprise Architecture Framework (EAF). EAF presents a comprehensive and transparent map of an organization showing how all organization elements (business and IT) work together to achieve defined business objectives. It clarifies the way in which these elements support the business processes of the organization. Several distinctive EAF have been proposed till now, the main challenges any of these EAF faced are (1) defining process is heavy, prolonged and tedious (2) Keeping EA artifacts up-to-date is an awkward work. These challenges make the artifacts of EA useless and unreliable. A number of researchers and practitioners try to eliminate these challenges by using Service Oriented (SO) paradigm with common and famous EAF like Zachman and FEAF. But none of them completely clarify how SO practices with EA concepts combination may be realized and what are the important elements of it, they just show an abstract mapping between these two concepts and state that this combination can be possible. In this article we try to present a service oriented EAF (SOEAF) to eliminate aforementioned challenges and elaborated this framework in details. CEA Framework involves a SO Roadmap that is completely compatible with ITIL and a Classification Schema that cover all aspects of organization, these aspects categorize according to Purpose, Pattern or Practice, Policy, Stakeholder and Resource. We believe that by using the proposed SOEAF referred to as CEA Framework, created enterprise architecture is flexible and agile enough to define rapidly and sense the environment quickly then, adapt and adopt business and information changes appropriately.

Title:	IMPACT OF INFORMATION TECHNOLOGY ON EMPLOYMENT OF WOMEN IN SAUDI ARABIA
Author:	SULAIMAN A. AL-HUDHAIF, NISAR AHAMAD NALBAND
Source:	Journal of Theoretical and Applied Information Technology pp 172 - 177 Vol. 40. No. 2 -- 2012
Abstract	The world across and in Saudi Arabia, women’s roles, has been traditional. Saudi laws are based on the Shari’a, which besides giving much freedom to women guarantees a right to work as well, but practice stipulates that women should work in a decent, appropriate environment, that is, not mixing with men or being exposed to nuisance. Hence, gender segregation in professional jobs is prominently seen. The focus of this paper is on the use of information and communications technologies (ICT) to generate employment for women, particularly in a country like Saudi Arabia, where cultural barriers are present; attention is paid to explaining about the challenges for women’s employment in Saudi Arabia and the best practice and strategies that can be applied by organizations in tapping a potential resource that is going unnoticed, and the efforts of the government of Saudi Arabia to promote the employment of women.

Title:	NEW CONTROL STRATEGY TO REDUCE THE FLUCTUATIONS OF THE DC BUS OF A WIND TURBINE USING THE DFIG.
Author:	TARIQ RIOUCH, RACHID EL BACHTIRI
Source:	Journal of Theoretical and Applied Information Technology pp 179 - 187 Vol. 40. No. 2 -- 2012
Abstract	The wind turbine based on the doubly-fed induction generator (DFIG) plays an increasingly important role in power generation. This is thanks to the benefits of these generators compared to other machines. In this paper, we present a new control strategy that limits variations and the transient overshoots in the DC bus voltage, which cause problems and sometimes leads to destruction of converters (GSC) and (RSC). Good performance of DFIG depends strongly on the stability of the DC bus. Simulations on Matlab / simulink/ SimPowerSystems validate the effectiveness of our approach.

Title:	CLOUD MONITORING BASED ON SNMP
Author:	J. SWARNA, C. SENTHIL RAJA, DR.K.S.RAVICHANDRAN
Source:	Journal of Theoretical and Applied Information Technology pp 188 - 193 Vol. 40. No. 2 -- 2012
Abstract	With the new trend in the industry being everyone playing the role of a cloud player, lots of pressure has been mounted on them as to how the resources are efficiently managed, thus providing elasticity to the end-user’s demands. When coming to a networked environment with larger hosts, especially in a cloud environment, the monitoring tool should well be capable of handling the load and reproduce the results in quicktime. In lots of cases SNMP based monitoring proves worthy of the effort being put irrespective of the size of the environment. Using SNMP MIBs may prove to be an effective approach for dealing with the underlying information of different hosts in a cloud environment. The monitoring tool is also capable of dealing with the SNMP checks.

Title:	AN OPTIMAL AND COST EFFECTIVE KEY MANAGEMENT SCHEME FOR SECURE MULTICAST COMMUNICATION
Author:	SRIDHAR J K , SENTHIL KUMAR R , ARUN KUMAR S
Source:	Journal of Theoretical and Applied Information Technology pp 202 - 207 Vol. 40. No. 2 -- 2012
Abstract	The recent growth, popularity and extensive need for the deployment of group oriented applications like multiparty video conferencing, multiplayer online gaming and real time push based delivery systems has triggered the demand for secure group communication. These applications require multicast to minimize the volume of network traffic they generate. Multiparty communications have recently become the focus of new developments in the area of applications. The goal of this paper is to establish a secure group communication using multicast key distribution scheme. In general, to meet forward secrecy and backward secrecy, any change in the group membership will induce group rekeying. Here, a novel key management scheme is proposed in which no redistribution of group key (shared key) is required during the group dynamics there by reducing computation and communication complexities considerably.

Title:	ANALYSIS DATA OF STUDENT’S GPA AND TRAVELLING TIME TO CAMPUS USING CLUSTERING ALGORITHM AFFINITY PROPAGATION AND K-MEANS
Author:	S. JATMIKO, R.REFIANTI, A.B. MUTIARA, R. WARYATI
Source:	Journal of Theoretical and Applied Information Technology pp 213 - 217 Vol. 40. No. 2 -- 2012
Abstract	In most of clustering algorithm, the cluster number and member are generated randomly, called common method. Consequently, the result may vary from the same clustering process. K-means algorithm is one example of these common methods. Affinity propagation, called new method, is developed to overcome this drawback by exchange the messages between data points to test the feasibility and accuracy of all data points to become exemplar and using it to select the cluster members. The aim of this research is to compare and analyse both methods by applying these method for clustering the student grade point average (GPA) and travel time to campus data. Both algorithms are implemented using Matlab 7.11.
