Abstract	The present paper deals with the 4th wave of the Information Security as a new approach to governance of information security. After introducing the four waves of information security, is focused on the last part which will be part of our thesis. Based on the three waves in the development of Information Security, Information Security development is presently in its Fourth Wave. This wave reflects the development of Information Security Governance as a result of the emphasis on good Corporate Governance. The Fourth Wave of Information Security can therefore be defined as the process of the explicit inclusion of Information Security as an integral part of good Corporate Governance, and the maturing of the concept of Information Security Governance. We as Information Security practitioners must use this development to its optimum to ensure the security of IT systems. In addition, following the PDCA approach (Plan, Do Check, Act), we will establish an inventory of information system with the SoM (Statement of Maturity), a risk assessment of assets, a business continuity plan to ensure a resumption of IT.

Title:	AN APPROACH TO DESIGN INCREMENTAL PARALLEL WEBCRAWLER
Author:	DIVAKAR YADAV, AK SHARMA, SONIA SANCHEZ-CUADRADO, JORGE MORATO

Abstract	World Wide Web (WWW) is a huge repository of interlinked hypertext documents known as web pages. Users access these hypertext documents via Internet. Since its inception in 1990, WWW has become many folds in size, and now it contains more than 50 billion publicly accessible web documents distributed all over the world on thousands of web servers and still growing at exponential rate. It is very difficult to search information from such a huge collection of WWW as the web pages or documents are not organized as books on shelves in a library, nor are web pages completely catalogued at one central location. Search engine is basic information retrieval tool, used to access information from WWW. In response to the search query provided by users, Search engines use their database to search the relevant documents and produce the result after ranking on the basis of relevance. In fact, the Search engine builds its database, with the help of WebCrawlers. To maximize the download rate and to retrieve the whole or significant portion of the Web, search engines run multiple crawlers in parallel. Overlapping of downloaded web documents, quality, network bandwidth and refreshing of web documents are the major challenging problems faced by existing parallel WebCrawlers that are addressed in this work. A Multi Threaded (MT) server based novel architecture for incremental parallel web crawler has been designed that helps to reduce overlapping, quality and network bandwidth problems. Additionally, web page change detection methods have been developed to refresh the web document by detecting the structural, presentation and content level changes in web documents. These change detection methods help to detect whether version of a web page, existing at Search engine side has got changed from the one existing at Web server end or not. If it has got changed, the WebCrawler should replace the existing version at Search engine database side to keep its repository up-to-date

Title:	USING GLOBAL FEATURES ON REFINED IMAGE PARTS FOR LOGO RECOGNITION
Author:	AHMED ZEGGARI, FELLA HACHOUF
Source:	Journal of Theoretical and Applied Information Technology pp 030 - 038 Vol. 43. No. 1 -- 2012
Abstract	In this paper we address the problem of what parts of an image can be used to well perform content-based image retrieval system. Local parts are selected and refined based on the clustering of interest points obtained by Harris corners and minimum bounding box detectors. Global features such as invariant moments and color histograms of the extracted local regions are combined to find similar logos on the database. Several inter-regions distances are compared to perform inter-images similarity based on the minimum average distance of the individual components. Our system is tested on logo and trademark databases; results demonstrate a good retrieval rate and tolerance to logo distortions such as rotation, occlusion and some amount of noise.

Source:	Journal of Theoretical and Applied Information Technology pp 039 - 044 Vol. 43. No. 1 -- 2012
Abstract	Mobile phone is one of the most widely used today in mobile communications. This technology is very useful for communication but this raises several problems in a situation where silence is required such as in libraries, places of worship, classrooms and others. Mobile phone jammer is a device that used to block the incoming signal to a mobile phone from the base station. If the mobile phone jammer is turned on then it can’t form the incoming or outgoing calls even sms. In this research, we designed a Yagi antenna (900MHz) to expand the range of jamming because Yagi has a great gain. Results of impedance by gamma match are 50.16 $\Omega$. Obtained the value of VSWR Yagi is 1.46:1 and jamming distance that can be taken approximately 16 meters, It is different from the jamming distance of helical antenna on a mobile phone jammer itself is about 4 meters.

Source:	Journal of Theoretical and Applied Information Technology pp 045 - 051 Vol. 43. No. 1 -- 2012
Abstract	Organizations with the infrastructure and skills to implement highly virtualized IT operations may consider a private cloud—a multi-tenant, highly scalable and automated infrastructure—part of the enterprise data center’s natural evolution. But before you commit to a private cloud, you need to understand associated costs and tradeoffs. This paper tires to analyze and brief up the costs and the needs for organizations who want to implement private cloud. Since so much of costs are involved in establishing private clouds for organizations, this paper attempts to show the real facts behind the private cloud costs.

Title:	A NEW MAINTENANCE TIME MEASUREMENT METHOD BY VIRTUAL REALITY
Author:	KANG LE , ZHOU DONG, LV CHUAN
Source:	Journal of Theoretical and Applied Information Technology pp 074 - 081 Vol. 43. No. 1 -- 2012
Abstract	Virtual maintenance has emerged as one such technology which has attained maturity and gained acceptance in industry. The key contribution of virtual maintenance is to reduce the design cost and cycle. Currently, virtual maintenance verification focuses on these statically qualitative contents, and there is a big gap between virtual maintenance simulation time and actual maintenance time. This paper divides those causes for the gap into three parts, including integrity, determinacy and verisimilitude. A new virtual maintenance time measurement based on DELMIA has been raised aiming at reducing the effects of the verisimilitude causes. And qualitative and quantitative analysis has been combined together to improve products’ maintainability.

Title:	NEW ALGORITHM FOR COLOR IMAGE ENCRYPTION USING CHAOTIC MAP AND SPATIAL BIT-LEVEL PERMUTATION
Author:	RUI LIU, XIAOPING TIAN
Source:	Journal of Theoretical and Applied Information Technology pp 089 - 093 Vol. 43. No. 1 -- 2012
Abstract	With the fast progression of data exchange in electronic way, information security is becoming more important in data storage and transmission. This paper proposed a new algorithm for color image encryption using chaotic map and spatial bit-level permutation (SBLP). Firstly, use Logistic chaotic sequence to shuffle the positions of image pixels, then transform it into a binary matrix including the red, green and blue components simultaneously, and permute the matrix at bit-level by the scrambling mapping generated by SBLP. Secondly, use another Logistic chaotic sequence rearrangement of the position of the current image pixels. Experiment results and security analysis show that the algorithm can achieve good encryption result and low time complexity, in addition, the key space is large enough to resist against common attack.

Title:	UNSUPERVISED CLUSTERING OF GENE EXPRESSION PROFILES OF MICROARRAY DATA USING LIM AND PCA IN BIOINFORMATICS
Author:	R. SHANMUGAVADIVU, Dr. N. NAGARAJAN
Source:	Journal of Theoretical and Applied Information Technology pp 094 - 102 Vol. 43. No. 1 -- 2012
Abstract	The development of microarray technology produces massive gene expression data sets. A major task for the experimentalist is to understand the structure in the huge data sets. Data generated by a scientific experiment always contain random noise. The situation is worst in the area of biology. Statistical methods must be used to accurately interpret large-scale experimental data. Microarray data is represented as a matrix with rows representing individual genes and columns representing conditions or experiments and very heterogeneous in nature. Because many proteins have unknown functions, and because many genes are active all the time in all kinds of cells, researchers usually use microarrays to make comparisons between similar cell types. As a result, we need to develop our ability to ‘‘see’’ the information in the massive tables of quantitative measurements that these approaches produce. This research addresses a suitable Micro array data clustering Algorithm which can be used to rearrange the gene expression profiles of microarray data for easy observation and knowledge discovery. In this research, a Lorenz Information Measure(LIM) based algorithm will be used to order the microarray data and after ordering the data, Principal Component Analysis(PCA) will be used to find the principal components in that order. Then the data will be clustered using a special kind of neural network called Self Organizing Maps (SOM).The Microarray data displayed after grouping will have some significance. After the clustering, we can see that the genes with similar expression patterns are grouped together under the related set of conditions. The Implementation of the proposed model will be done using Mat lab 6.5 under Windows operating system. The Performance of the system will be tested and evaluated with suitable gene expression data available for such kind of research.

Title:	EVALUATION OF FREQUENT-PATH ADAPTABILITY ASPECT IN ADWEF APPLYING BASIC BUSINESS PROCESSES
Author:	FARAMARZ SAFI ESFAHANI, MASRAH AZRIFAH AZMI MURAD
Source:	Journal of Theoretical and Applied Information Technology pp 103 - 111 Vol. 43. No. 1 -- 2012
Abstract	Centralized business process execution in the Service Oriented Architecture (SOA) suffers from lack of scalability. Decentralization of business processes is introduced as an alternative approach to address this shortcoming. However, decentralization methods do not consider adaptability of created fragments with runtime environment. The Adaptable and Decentralized Workflow Execution Framework (ADWEF) introduces frequent-path and proportional-fragment adaptability aspects along with two architectures Type-1 and Type-2 and two decentralization methods HPD and HIPD. The ADWEF has been tested for several boundary-condition and one complex business processes; nonetheless, the behavior of prominent activities of business processes has not been studied yet. This paper introduces If-process, While-process and Flow-process as three basic business processes to study the behavior of their central activities from frequent-path adaptability point of view in terms of response-time and throughput running on architecture Type-1. Evaluations of the basic processes show that considering the frequent-path adaptability provides a range of improvements in response-time and throughput with variable-request-rate/constant-message-size and constant-request-rate/variable-message-size configurations.

Abstract	Lots of fourth generation (4G) wireless networks are currently being deployed globally with similar or with dissimilar technologies in various operating bands. In this paper, spectrum sharing and coexistence scenarios of the 4th generation networks in the band (2500-2690) MHz are addressed. Interferences from Long Term Evolution (LTE) to Worldwide Interoperability for Microwave Access (WiMAX) systems and vice versa are carefully investigated. The collocation and coexistence requirements in terms of separation requirements as well as additional isolations are fully addressed. Interference measures of the two systems as functions of adjacent channel interference power ratios are also considered. Finally, the impact of deployment morphologies of the two systems is accounted for by catering for losses due to surrounding clutter.

Title:	FEATURE SELECTION OF FREQUENCY SPECTRUM FOR THE BALL MILL LOAD BASED ON INTERVAL PARTIAL LEAST SQUARES
Author:	LIJIE ZHAO, XUE FENG, DECHENG YUAN, 1 HUI XIAO
Source:	Journal of Theoretical and Applied Information Technology pp 119 - 126 Vol. 43. No. 1 -- 2012
Abstract	Due to highly complex of the grinding mechanism of the ball mill, it is a challenging problem to select the informative frequency spectral features of the response signals. High dimensionality and co-linearity of the frequency spectrum are unfavorable to build the effective mill load model in the wet ball mill. Interval Partial Least-Squares Regression (iPLS) is applied to select the feature frequency bands of the shell vibration signal and acoustical signal, which are closely relevant to the parameters of ball mill load. Redundant or irrelevant frequency spectral variables are removed to improve the complexity of ball mill load model and enhance the comprehension of the grinding process using the frequency spectrum features. The experimental results have demonstrated that the performance of the mill load models based on feature spectrum outperforms the full spectrum model for both the shell vibration signal and acoustical signal.

Title:	A NEW DELAY-DEPENDENT STABILITY CRITERIA FOR NETWORKED CONTROL SYSTEMS
Author:	BING LI, JUNFENG WU
Source:	Journal of Theoretical and Applied Information Technology pp 127 - 132 Vol. 43. No. 1 -- 2012
Abstract	In this paper, the problem of stability for networked control systems (NCSs) is investigated. Considering both the time-varying network-induced delay and data packet dropouts, NCSs are transformed into typical linear systems with interval time-varying delay. Based on the obtained model, a new delay-dependent stability criteria in terms of linear matrix inequalities (LMIs) is provided by constructing a novel time-dependent Lyapunov-Krasovskii functional. The tighter integral inequalities are used to deal with the cross-product terms arose from the time derivative of the Lyapunov-Krasovskii functional for obtaining much less conservative result. Compared with some previous ones, the proposed method introduces fewer matrix variables and has less conservatism. A numerical example is provided to demonstrate the effectiveness and the benefits of the proposed method.

Source:	Journal of Theoretical and Applied Information Technology pp 133 - 140 Vol. 43. No. 1 -- 2012
Abstract	Rough set is a powerful mathematical tool that has been applied widely to extract knowledge from many databases. However, some drawbacks have been detected in rough set, such as inconsistency, lack of flexibility, excessive dependency on discretization of the initial attributes and so on. To overcome these drawbacks, we propose an improved rough set combined with agglomerative clustering. The concept of equivalence class is also incorporated to merge and divide subclass. The experimental results show the better performance of the proposed approach.

Source:	Journal of Theoretical and Applied Information Technology pp 141 - 147 Vol. 43. No. 1 -- 2012
Abstract	On-machine measurement(OMM) based on machine vision has been hot research topic in recent years because coordinate measuring machine(CMM) measurement requires significant resources in operating time and cost. This paper aims to develop an OMM method with a manipulator and industry camera. First, an on-machine calibration method of industry camera based on image sequence is studied. A set of monocular stereo system was established on the NC milling machine. A calibration target was designed to meet the requirements of finding enough and accurate correspondence relationship. Calibration method is illustrated involving taking image sequence, detecting the position of the calibration board and the marking points, finding the marking points’ correspondence with their projection, determining the camera parameters through optimization algorithm. Accuracy of calibration shows that choosing 10 calibration images is appropriate for on-machine calibration. Second, image mosaic method for on-machine measurement of large-scale workpiece is investigated. Image sequences were acquired by controlling the moving of working table. Image mosaic of large-scale workpiece was realized with high precision. Size measurement result proved the effectiveness and high efficiency of this OMM system.
