Title:	ARABIC TEXT CATEGORIZATION: A COMPARATIVE STUDY OF DIFFERENT REPRESENTATION MODES
Author:	ABIDI KARIMA, ElBERRICHI ZAKARIA, TLILI GUISSA YAMINA
Source:	Journal of Theoretical and Applied Information Technology pp 001 - 005 Vol 38. No. 1 -- 2012
Abstract	The quantity of accessible information on Internet is phenomenal, and its categorization remains one of the most important problems. A lot of work is currently focused on English rightly since; it is the dominant language of the Web. However, a need arises for the other languages, because the Web is each day more multilingual. The need is much more pressing for the Arabic language. Our research is on the categorization of the Arabic texts, its originality relates to the use of a conceptual representation of the text. For that we will use Arabic WordNet (AWN) as a lexical and semantic resource. To comprehend its effect, we incorporate it in a comparative study with the other usual modes of representation (bag of words and Ngrams), and we use different similarity measures. The results show the benefits and advantages of this representation compared to the more conventional methods, and demonstrate that the addition of the semantic dimension is one of the most promising approaches for the automatic categorization of Arabic texts.

Title:	FIELD STUDY BASED ON SOFT COMPUTING TECHNIQUES
Author:	KARTHIGA. N, B. SANTHI
Source:	Journal of Theoretical and Applied Information Technology pp 035 - 040 Vol 38. No. 1 -- 2012
Abstract	Usage of soft computing techniques in field study saves human labor. Field study plays a vital role in the economic importance of agriculture which in turn results in poverty reduction. Farmers guess the solutions to the disease based on the loss of plant life that occurred previously. Technology is used to support farmers and botanist which give precise solution for the vague input information. The human labor used in the existing system is replaced with technology in the proposed system which reduces the time complexity, increases the performance and overcomes the lack of satisfaction. Decision Support System is the computer-based expert information system to predict the output response of field with respect to the input parameters. Fuzzy Control application is programmed in Fuzzy Control Logic (FCL). In fuzzification the value of the input variables are converted into degrees of membership for the membership functions defined on that variable. Fuzzy set is any set that allows its members to have different grades of membership in the interval [0, 1]. Smartness of the fuzzy depends on the rule evaluation. The performance of the fuzzy machine is restricted by the capability of human brain. DSS based fuzzy system provides interactive, flexible and quick decision making. Use of latest technology provides profitable performance to the farmers. The limitations in existing system are overcome by using relational database which is used as database in field study through which large queries can be handled easily. Fuzzy logic is a powerful concept of handling non-linear, time-varying, adaptive systems. The knowledge-driven DSS is created for crop management in proposed system.

Title:	CLOSED LOOP CONTROL OF A NOVEL EFFICIENT THREE OUTPUT PORTS DC-DC CONVERTER WITH ZERO VOLTAGE SWITCHING
Author:	T. NAGESWARA RAO, DR. V.C. VEERA REDDY
Source:	Journal of Theoretical and Applied Information Technology pp 041 - 048 Vol 38. No. 1 -- 2012
Abstract	Multiport converters, a promising concept for alternative energy systems, have attracted increasing research interest recently. Compared with the conventional approach that uses multiple converters, a multiport converter promises cost-effective, flexible and more efficient energy processing by utilizing only a single power stage. This paper presents a three output port single stage converter. To reduce the switching losses and henceforth to improve efficiency of converter system, Zero Voltage Switching (ZVS) is employed. The proposed multi output port converter with soft switching is simple and efficient. The analysis is carried out for both open loop and closed loop control. The simulation results for the same are presented in this paper.
Keywords	Multiport DC-DC converter, Single stage converter, Zero Voltage Switching, Soft Switching, Closed Loop Control of DC-DC Converter.

Title:	FINGERPRINT LOOKUP-AN EFFECTIVE AND EFFICIENT BACKUP USING DEDUPLICATION TECHNIQUE
Author:	VELVIZHI J, BALAJI C G
Source:	Journal of Theoretical and Applied Information Technology pp 049 - 054 Vol 38. No. 1 -- 2012
Abstract	Data deduplication avoids redundant data in the storage of backup operation. Deduplication reduces storage space and overall amount of time. In this system, files that contain data are split into chunks by using context aware chunking and fingerprints lookup to each chunk. Backup storage process is for avoiding duplicate data using fingerprints lookup. In this paper, we compare three methodology of backup systems such as full backup, cumulative incremental backup and differential incremental backup. Full backups contain all data file blocks. Cumulative incremental backups contain blocks from level n-1 or lower. Restoration speed is faster than differential incremental backup but storage space occupy much more. Differential incremental backups contain only modified blocks from level n or lower. The processes of differential incremental backup in which data objects changes made since the last full backups are copied.

Title:	MODELING BIO INSPIRED SYSTEMS: TOWARD A NEW VIEW BASED ON MDA
Author:	SEIF EDDINE MILI , DJAMEL MESLATI
Source:	Journal of Theoretical and Applied Information Technology pp 063 - 073 Vol 38. No. 1 -- 2012
Abstract	Biologically inspired complex systems are increasing. As the abstractions presented by biologically inspired systems, systems architects will be required to include the abstractions in their architecture in order to communicate the design to system implementers. The paper argues that in order to correctly present the architectures of bio inspired system a need of bio inspired views will be required. The paper describes a new formalism based on biology and Model Driven Architecture (MDA) in order to find a new and easy way to design and understand (reverse engineering) a complex bio inspired system. The paper also describes then a set of bio inspired views which are used when describing bio inspired system. Finally we use the proposed approach to model Xor artificial neural network.

Title:	A NOVEL CRYPTOGRAPHIC ARCHITECTURE
Author:	R THANUJA, S DILIP KUMAR
Source:	Journal of Theoretical and Applied Information Technology pp 074 - 078 Vol 38. No. 1 -- 2012
Abstract	The goal of cryptography is to make it possible for two people to exchange a message in such a way that other people cannot understand the message. There is no end to the number of ways this can be done, but here we will be concerned with methods of altering the text in such a way that the recipient can undo the alteration and discover the original text. Today the modern cryptography is based on efficient algorithms for encryption that is used to provide better security. Asymmetric and Symmetric are nowadays designed with some complex function or key generations concept to provide security service in better manner. But, still now there are some attacks are reported even on modern cryptographic algorithms. In this paper we are going to propose a Novel Cryptographic architecture that uses IDEA &BLOWFISH algorithm for encryption purposes and using of SHA-I for generating hash value for cipher text in order to provide a strong cryptographic architecture.

Abstract	Security in Wireless Sensor Network plays an important role in the node communication. The significant growth is existed for developing the wireless sensor network applications. The key features of Wireless sensor networks are low power, low-memory, low-energy and having bulky scaled nodes. Due to this various facts the existing security algorithms are not appropriate for current applications. This causes the research to propose the novel security mechanisms which contains minimum resource consumption and maximum security. Many papers have been developed in this field. This paper is to isolate the security issues in layer level, key management and routing framework.

Title:	RETROSPECTION OF SVM CLASSIFIER
Author:	NANDHINI.K, B.SANTHI
Source:	Journal of Theoretical and Applied Information Technology pp 083 - 088 Vol 38. No. 1 -- 2012
Abstract	SVM (Support Vector Machine) is a supervised learning which is a boon in disguise to the field of machine learning. Though a number of classifier seems to exist it gives better result and recognition rates for which it is opted the most. The other brighter side of SVM is that it minimizes the empirical error and maximizes the geometric region. Neural network has weakness such that they converge only to the locally best solutions. Whereas, SVM is far improved. SVM has the capability to select its own support vectors. In case of Back Propagation algorithm, we should know in advance the value of the output and once we receive a value after passing through the neurons, the two values are compared and if there is no match found, backtracking is done as a result of which weights are varied to obtain the exact value. The computational complexity is going to be very great. It proves to be a useful tool when the data is not regular or when the distribution is unknown. SVM gains its flexibility from the kernel which in turn makes it successful. This can provide a unique solution whereas neural networks have multiple solutions for each minima so it does not seem to be robust for different samples. The greater recognition rate and flexibility makes SVM popular. Accuracy, recognition rate is very important for the purpose of classification, only then authentication can be done effectively. This study has been evolved to reveal that SVM gives good accuracy and recognition rate compared to other classifiers and hence it is considered best for gait recognition.

Title:	USING OF LDPC CODES IN STEGANOGRAPHY
Author:	I. DIOP1, S .M FARSSI, M.CHAUMONT, O. KHOUMA, H. B DIOUF, K .TALL, K .SYLLA
Source:	Journal of Theoretical and Applied Information Technology pp 103 - 109 Vol 38. No. 1 -- 2012
Abstract	Steganography is the art of secret communication [1] Since the advent of modern steganography, in the 2000s, many approaches based on error correcting codes (Hamming, BCH, RS ...) have been proposed to reduce the number of changes in the roof while inserting the maximum bit. Jessica Fridrich's works have shown that sparse codes best approach the theoretical limit of efficiency of insertion. Our research works are a continuation of those on low-density codes (LDGM) proposed by T. Filler in 2007. In this paper we propose a new approach to correcting codes using LDPC codes rather than LDGM. The complexity of our approach is much less than that of T. Filler which makes it usable in practice.

Title:	GUIDELINES FOR TACIT KNOWLEDGE ACQUISITION
Author:	ADEL HAMDAN MOHAMMAD, NEDHAL ABDUL MAJIED AL SAIYD
Source:	Journal of Theoretical and Applied Information Technology pp 110 - 118 Vol 38. No. 1 -- 2012
Abstract	Knowledge is mainly divided into two parts explicit and tacit. There are several studies which talk about explicit knowledge, but actually few studies talk about tacit knowledge. Tacit knowledge is an important issue which needs more exploration so authors are recently focusing on. The nature of tacit knowledge makes acquiring and extracting tacit knowledge not an easy task since it is complicated in its nature. As a result this research talks about tacit knowledge. Also authors explain main characteristics of tacit knowledge. Authors think that this research is worth reading because it covers and analyzes most relevant research which talks about tacit knowledge. More over it develops guidelines for acquiring and extracting tacit knowledge. This developed Guideline can be used for almost large organizations with a little adaptation related to job nature of the organizations. Finally, applying our guideline will facilitate acquiring tacit knowledge without wasting a huge amount of cost or effort.
