Title:	SOCIAL KNOWLEDGE NETWORK AS AN ENABLING FACTOR FOR ORGANIZATIONAL LEARNING
Author:	ADEL AL-HASHEM, AMIN SHAQRAH
Source:	Journal of Theoretical and Applied Information Technology pp 001 - 008 Vol. 40. No. 1 -- 2012
Abstract	Organizational learning is a set of processes by which organizations improve their performance. Learning processes furthermore require that the organization anticipates and attends to feedback, creates knowledge from that feedback, and takes action based on that knowledge. The relationships among people can be modeled as social knowledge networks in which network nodes represent people and network graph represent relationships for sharing opinions, experiences, insights, perceptions, and various media, including photos, videos, and music, with each other. Social knowledge networks play supportive role for collaborative knowledge management phases -creation, capture, codify, communicate, and capitalize knowledge.

Title:	MINING DATA TO REDUCE SHRINKAGE IN ORGANIZED RETAIL
Author:	G.PAVITHRA, R.S.SARANYA, P.S.RAMESH

Abstract	Shrinkage is a reduction in inventory due to shoplifting, employee theft, paper work errors and supplier fraud. If the shrinkage amount is large for a company obviously it will result in the net profit deterioration. In this paper we propose a model to reduce shrinkage in a retail industry using data mining. The barcode of a product is taken as the primary key. The access to this key should be with one trusted party and the remaining database can be accessed by anyone. Maintaining barcode for the product types such as stationery, groceries will solve this problem. This is done by using the data mining tool and presented in a pictorial representation. For instance, in the observed pattern if the quantity of the barcoded product exceeds the quantity of the product available, it can be identified as a shoplifted item. Using the tool the data pattern extracted from the dataset will contain the information of that particular item. Thus the theft can be identified and prevented. The reliability of our model lies in the trust of the administrator who can access the primary key.

Abstract	Fault in induction motor is crucial problem in industrial processes. This paper presents the system for electrical fault detection in induction motor fed by inverter. Current spectrum with different frequency is used to fault monitoring. Faults observed includes variation of frequency, unbalance voltage, and inter turn short circuits. Through an experiment, the fault was fired and the current spectrum recorded at steady state condition. Preprocessing is performed before the identification process. It includes noise reduction using wavelet analysis and feature extraction with Principal Component Analysis (PCA). Both processes are intended to eliminate the noise, reducing the dimension of feature, and retrieve components of the optimal features for classification. Strength of identification capability using Support Vector Machine (SVM) is 83.51%. Based on the ROC (Receiver Operating Characteristic) analysis, the SVM classifier has a good enough performance. This is indicated by the sensitivity is 74.31%, specificity is 47.30% and G-Mean is 1.1028.
Keywords	Electrical Fault Detection, Induction Motor, Principal Component Analysis (PCA), Receiver Operating Characteristic (ROC), Support Vector Machine (SVM).

Abstract	This research seeks to look into a design process of the development of a model for teaching and learning traditional craft courseware called CDTC model. Specifically, this research focuses on analysis and design phase. The model was developed according to an established methodology and it is relied upon a conceptual framework consisting of four development phases starting from Analysis, Design, Development and Evaluation. The research begins with the preliminary analysis to look into the problems in conventional traditional apprenticeship method for teaching and learning traditional craft by looking at students and craft instructors' perceptions. Various weaknesses were identified in acquiring the craft skills taught to students especially when instructors need to teach a group of students. The results of analysis helps to suggest and determine a practical way to map out the suitable teaching environment and strategy that would best serve for teaching and learning traditional craft. As a result from initial analysis, the proposed CDTC model for educational courseware development for teaching and learning traditional craft was developed consisting of two main components. In Design phase, the proposed CDTC model's components was evaluated by selected craft instructors through initial validation process in order to verify its' components. The results from initial validation among instructors help in establishing and designing a preliminary version of the model.

Abstract	WEP (Wired Equivalent Protocol) is a wireless security protocol ratified by IEEE (The Institute of Electrical and Electronics Engineers) in 1999. Since then, WEP is widely used in telecommunication field. In daily usage, it had been phased-out by IEEE since 2005 to be replaced by WPA/WPA2 (Wi-Fi Protected Access). WEP encryption algorithm can be easily cracked because of its widely documented weaknesses. Nevertheless, WEP is still has been used extensively as a research topic in the academic field. Certain enterprises still using WEP due to lack of security consciousness, economical constraint or because it is difficult to replace the legacy communication devices in which WEP is already bulged. In this paper, we give a review on WEP wireless security protocol in terms of its history, weaknesses, improvements, and current alternative approaches to overcome its weaknesses regarding the protocol in ICT (Information and Communication Technology) field. This research aims to address WEP protocol in its current versions and to give a spirit future direction research to enhance its security mechanism.

Title:	STUDY OF ONTOLOGY OR THESAURUS BASED DOCUMENT CLUSTERING AND INFORMATION RETRIEVAL
Author:	G.BHARATHI, D.VENKATESAN

Abstract	Document clustering generates clusters from the whole document collection automatically and is used in many fields, including data mining and information retrieval. Clustering text data faces a number of new challenges. Among others, the volume of text data, dimensionality, sparsity and complex semantics are the most important ones. These characteristics of text data require clustering techniques to be scalable to large and high dimensional data, and able to handle sparsity and semantics. In the traditional vector space model, the unique words occurring in the document set are used as the features. But because of the synonym problem and the polysemous problem, such a bag of original words cannot represent the content of a document precisely. Most of the existing text clustering methods use clustering techniques which depend only on term strength and document frequency where single terms are used as features for representing the documents and they are treated independently which can be easily applied to non-ontological clustering. To overcome the above issues, this paper makes a survey of recent research done on ontology or thesaurus based document clustering.

Abstract	Wireless sensor network provides a useful method to acquire and monitor the physiological signals of a patient. Bluetooth has a wide variety of applications in the medical field. Previously in a patient monitoring system, the physiological signals of a patient are transferred by using piconet. And it has some drawbacks such as limited number of nodes and limited communication range. To overcome these drawbacks, we proposed a system using Bluetooth scatternet. In this proposed model three piconets are interconnected to form Scatternet Sensor Network. The first and second piconet consists of one master node (local nurse) and five slaves nodes (patients). The third piconet consists of one master node (Chief nurse) and three slave nodes (Chief Doctors). Chief nurse act as a bridge node, which interconnect three piconets. The patients are at 24×7 critical care. If anything critical occurs, the Chief Doctor receives the data and sends acknowledge to the concerned patient. Furthermore, with the help of this system, medical personnel can take care of a few patients simultaneously, and thus, the personnel expenses can be reduced.

Author:	K.RANJITH KUMAR, S. PALANISWAMI, M.MANIKANDAN
Source:	Journal of Theoretical and Applied Information Technology pp 067 - 077 Vol. 40. No. 1 -- 2012
Abstract	The paper presents a novel secondary reactance control technique in the rotor circuit of a three phase wound rotor induction motor (WRIM). The problem associated with the conventional rotor capacitive reactance control is the demand of exceptionally large capacitance requirement for enhancing the performance of the motor in wide operating range. In the proposed technique, a three phase bridge rectifier with a dynamic capacitor is used in the rotor circuit. The dynamic capacitor is H-bridge circuit with a capacitor in which the duty cycle of switching elements is varied for emulating the capacitance value dynamically and to be used as capacitive reactance control. A TMS320F2407 Digital Signal Processor (DSP) controller is used for delivering Pulse Width Modulation (PWM) pulses for appropriate switches. The performances such as speed, torque, power factor, efficiency, harmonics of the motor are analyzed for different speed and loading conditions. The feasibility of the proposed system is verified by simulation and experimental results.

Abstract	In this paper, we propose a recognition technique for handwritten Indian numbers. Due to the variations in shapes and sizes of handwritten Indian numbers, image representation, smoothing, skeletonization and localization processes are applied to further improve the classification performance. We employ five efficient classifiers RNN, DROP 1, DROP 2, DROP 3 and DROP 4 in our technique. New feature extraction method that divides the image of the handwritten Indian number into 16 sub blocks and 24 partition lines is proposed. For this feature extraction, a vector set is built with 41 attributes representing 16 sub blocks, 24 partition lines and one for the possibility of getting closed loop. Simulation results show that the above classifiers with the new proposed feature extraction improve the recognition accuracy with acceptable subset size. It is noted that DROP 3 method has the highest classification accuracy with good reduced memory size compared to other methods.

Title:	AN AUTOMATIC APPROACH FOR GENERATING TABLES IN SEMANTIC WIKIS
Author:	LULUAH AL-HUSAIN, SAMIR EL-MASRI
Source:	Journal of Theoretical and Applied Information Technology pp 089 - 097 Vol. 40. No. 1 -- 2012
Abstract	Wiki is well-known content management systems. Semantic wikis extends the classical wikis with semantic annotations that made its contents more structured. Tabular representations of information have a considerable value, especially in wikis which are rich in content and contain large amount of information. For this reason, we propose an approach for automatically generating tables for representing the semantic data contained in wiki articles. The proposed approach composed of three steps (1) extract the semantic data of Typed Links and Attributes from the wiki articles and call them Article Properties (2) cluster the collection of wiki articles based on extracted properties from the first step, and (3) construct the table that aggregates the shared properties between articles and present them in two-dimensions. The proposed approach is based on a simple heuristic which is the number of properties that are shared between wiki articles.

Title:	AN IMPROVED APPROACH IN FLOODING WITH PACKET REACHABILITY IN FSR (FISHEYE STATE ROUTING) PROTOCOL USING MANET
Author:	S. NITHYA REKHA, Dr.C.CHANDRASEKAR
Source:	Journal of Theoretical and Applied Information Technology pp 098 - 104 Vol. 40. No. 1 -- 2012
Abstract	Packet Reach ability and Broadcasting in Mobile Ad Hoc Networks (MANETs) is a fundamental data dissemination mechanism with a number of important applications, e.g., route discovery, address resolution. However broadcasting induces what is known as the ‘‘broadcast storm problem’’ which causes severe degradation in network performance due to excessive redundant re- transmission, collision, and contention. Broadcasting in MANETs has traditionally based on ﬂooding, which simply swamps the network with large number of rebroadcast messages in order to reach all network nodes. Although probabilistic ﬂooding has been one of the earliest suggested schemes to broadcasting, there has not been so far any attempt to analyze its performance behavior in a MANET environment. In an effort to fill this gap, this paper investigates using extensive NS-2 simulations the effects of a number of important system parameters in a typical MANET, including node speed, pause time, and node density on the performance of probabilistic ﬂooding. The results reveal that most of these parameters have a critical impact on the reach ability and the number of saved rebroadcast messages achieved by probabilistic flooding

The rapid changes of the behavior of the industry and all new inventions of technologies in different fields, it becomes really challenging to develop and deliver a large software product within time with full customer satisfaction. Over all the industry is getting very spry in nature. On other hand software is something we cannot see unless it is fully working or providing some output. Now human cannot predict the future or plan for uncertain changes in distant future. So to support the flexibility of the market the development process of such project also needs to be more flexible, more agile. Therefore agile software development methodology helps to develop a project in iterative and incremental way and scrum is one of the frameworks which help to implement agile methodology in a software project development.
