Title:	THE NEW METHOD OF ADAPTIVE CPU SCHEDULING USING FONSECA AND FLEMINGS GENETIC ALGORITHM
Author:	MEHDI NESHAT, MEHDI SARGOLZAEI, ADEL NAJARAN, ALI ADELI

Abstract	The CPU scheduling is one of the most important tasks of the operating system. Many algorithms are designed and used in this regard each having advantages and disadvantages. In this paper a new algorithm for the CPU scheduling is presented using FFGA (Fonseca and Fleming’s Genetic Algorithm) multiobjective optimization. Contrary to the classical algorithms in use, it uses the three parameters of CPU burst time; I/O devices service time, and priority of process instead of using one parameter of CPU burst time. The important point is the adaptation of the algorithm which selects a special process depending on the system situation. The performance of this algorithm was compared with seven classical scheduling algorithms (FCFS, RR (equal, prioritized), SJF (preemptive, non-preemptive, Priority (preemptive, non-preemptive)), and the results showed that the performance of the proposed method is more optimized than other methods. The proposed algorithm optimizes the average waiting time and response time for the processes.

Abstract	A software Radio which exploits unused spectrum spaces without causing much interference to licensed spectrum users and thus optimising the use of available radio frequency is, by its virtue of its intelligence, called Cognitive Radio. By judging the current trends in wireless technologies it can be predicted that Cognitive Radio will be a critical part of many future radio systems and networks. Cognitive Radio uses any of the three techniques – Spectrum Sensing, Spectrum Database and Cognitive Pilot Channel to acquire information about spectrum usage. Spectrum Sensing is the inherent ability of Cognitive Radio to autonomously perform required calculations and detect unused spectrum which can be used for a multitude of purposes. Due to its advantages many studies have been focussed to improve and implement Spectrum Sensing effectively in Cognitive Radio and this lead to development of many spectrum sensing schemes. This paper provides an insight into various Spectrum Sensing technologies and also analyses the advantages and drawbacks of each.

Title:	3G MOBILE TEST ASSET DEVELOPMENT
Author:	DINAH PUNNOOSE, K. CHAKRAPANI, P. SWAMINATHAN
Source:	Journal of Theoretical and Applied Information Technology pp 046 - 051 Vol 37. No. 1 -- 2012
Abstract	As mobile services and applications are becoming more pervasive with the increasing adoption of 3G networks and devices, verifying the different quality attributes in all parts of the system is important. This describes a testing platform for 3G User Equipment (UE) that allows effective testing of UE devices and applications in a laboratory environment. By simulating parts of the network, the platform provides a realistic yet controlled environment for testing. Using this platform, we have executed a number of tests on 3G UEs and applications. Based on our experiences we describe the specific challenges encountered in testing in a 3G network in contrast to testing in a more traditional environment. As the worldwide3G network deployment is scheduled for next upcoming years, mobile testing industry strives to supply test equipment with sufficiently good features to meet the needs .The biggest challenge is not only in customizing the new features quickly but also in making sure of the stability and robustness of the product. The test applications covered in this includes protocol conformance testing. Through practical experience, 3GPP has decided that the most efficient and cost-effective way to reach this goal is to create a certification system for mobile terminals. A certified mobile is tested to an agreed and continuously updated set of test cases. All test cases are developed, maintained and delivered by 3GPPand validated by a certification agreement group, such as the Global Certification Forum (GCF) or the Personal Communication System Type Certification Review Board (PTCRB)… The agreement group has the responsibility to ensure that each test case is performed on a range of commercially available test equipment, providing compatibility between test facilities. This paper describes an Automated Test-Bench Application for Mobile phones.

Title:	MULTI OBJECTIVE FDR PARTICLE SWARM ALGORITHM FOR NETWORK RECONFIGURATION OF DISTRIBUTION SYSTEMS
Author:	K.KIRAN KUMAR, Dr.N.VENKATA RAMANA, Dr.S.KAMAKSHAIAH
Source:	Journal of Theoretical and Applied Information Technology pp 060 - 069 Vol 37. No. 1 -- 2012
Abstract	This paper proposes a novel particle swarm optimization algorithm for Multi-Objective reconfiguration of distribution system named Multi-Objective Fitness Distance Ratio Particle Swarm Optimization Algorithm (MOFDR-PSOA) for minimization of power loss, voltage drop and to maintain better thermal limits of feeders with respect to their loading capabilities. In Conventional PSO all the solutions damps towards local pbest and thoroughly ignore other pbest points due to the convergence criteria and targets mainly on local optima than global optima. The proposed MOFDR-PSOA in contrast, considers local pbest points as well as neighbouring pbest values before arriving to gbest. This method thoroughly avoids premature convergence as well as convergence towards global optima. The effectiveness of the proposed method is demonstrated through IEEE 16 and 32 bus standard test systems.

Abstract	This paper discusses a passive method of suppressing conducted electromagnetic interference (EMI) on various pulse width modulation (PWM) DC/DC converters. Snubbers are circuits which are placed across semi conductor devices for protection and to improve performance. In this paper, passive snubber such as RLD and RCD snubber is experimented and a new combined snubber is proposed. The combined snubber is designed to support the buck, boost, buck boost and cuk converters. The common mode noise (CM) and differential mode noise (DM) is simulated using PSPICE version 9.0 software. The conducted noise is measured for with and without connecting the RLD, RCD and the proposed snubber. The simulated results were compared to recommend low emission converter among the various DC/DC converter topologies.

Title:	RADIOGRAPHIC IMAGES DATA MODEL FOR CONTENT-BASED RETRIEVAL
Author:	LILAC A. E. AL-SAFADI
Source:	Journal of Theoretical and Applied Information Technology pp 080 - 089 Vol 37. No. 1 -- 2012
Abstract	With the advance of multimedia technologies in general and diagnostic images technologies specifically, the number of radiographic images is constantly escalating in the biomedical field. This field demands sophisticated systems for management and effective search and retrieval of the radiographic images produced. This paper presents a semantic content-based radiographic image retrieval system that focuses on the semantic content of radiographic image documents to facilitate semantic-based radiographic image indexing and a retrieval system suitable for the radiographic image-on-demand style applications. The paper addresses a model developed for describing the semantic content of a radiographic image document and providing information about this content. It develops a sophisticated semantic radiographic image model that expresses the underlying semantic structure of radiographic images and retrieves content from different levels of details. The proposed semantic model is an extension of the traditional conceptual model which would be applied to the radiographic image domain. The proposed model would divide a radiographic image document, based on its semantic content, and would be converted into a logical structure or a semantic structure. The logical structure represents the overall organization of information. The semantic structure, which is bound to logical structure, is composed of semantic objects with interrelationships in the various spaces in the radiographic image.

Title:	LOAD BALANCING AS A STRATEGY LEARNING TASK
Author:	K. KUNGUMARAJ, T. RAVICHANDRAN
Source:	Journal of Theoretical and Applied Information Technology pp 090 - 095 Vol 37. No. 1 -- 2012
Abstract	A distributed system consists of independent workstations connected usually by a local area network. Load Balancing system puts forward to a new proposal to balance the server load in the distributed system. The load balancing system is a set of substitute buffer to share the server load, when their load exceeds its limit. The proposed technique gives an effective way to overcome the load balancing problem. Serving to more number of client requests is the main aim of every web server, but due to some unexpected load, the server performance may degrade. To overcome these issues, network provides an efficient way to distribute their work with the sub servers which is also known as proxy servers. Allocating work to the sub server by their response time is the proposed technique. The secure socket layer with Load balancing scheme has been introduced to overcome those server load problems. Storing and serving effectively and securely is more important so that desired algorithm is going to implement for load distribution and security enhancement named as Secure Socket Layer with Load Balancing and RSA Security algorithm respectively. Calculating response time of each request from the clients has been done by sending an empty packet over the networking to all the sub servers and response time for each sub server is calculated using the Queuing theory. In this Load Balancing system, the SSL based load distribution schemes has been introduced for better performance.

Title:	DESIGNING AND IMPLEMENTING INDIVIDUAL IDENTIFICATION SYSTEM BASED ON IRIS COLORS
Author:	A. RAMADONA NILAWATI, SARIFUDDIN MADENDA
Source:	Journal of Theoretical and Applied Information Technology pp 096 - 104 Vol 37. No. 1 -- 2012
Abstract	Currently, a number of biometric identification having been implemented as components of a variety of security system are fingerprint, palm geometry, face, facial thermo-graph, hand vein, signature, speech, eye iris and retina. It has been identified that the iris of the eyes has unique pattern/texture and color characteristics for every single individual, so that it has now been used as a component of a biometric system. A number of iris identification algorithms have been developed and applied in security systems; however, because such algorithms have only been based on the iris pattern characteristics, the results have not yet been optimum. This is caused by the fact that the result of extracting iris patterns is quite susceptible to the changes of light intensity and the movement of position in the process of iris image acquisition. This paper proposed a new model of identifying an iris based on an iris color with the aid of a 3-dimension color bin histogram. The advantage of using iris colors is that they are not quite sensitive to even small changes of light intensity and position. This kind of model has successfully been implemented as a system prototype by integrating a number of algorithms developed in the research. The trial run has been carried out by the use of a database containing 1877 iris images and 322 samples of test images. The analysis result indicates that the accuracy level of the developed system is relatively very good with the error rate of around 8 %.

Source:	Journal of Theoretical and Applied Information Technology pp 112 - 115 Vol 37. No. 1 -- 2012
Abstract	The signals obtained from a system generally contain a number of unwanted information, termed noise, which needs to be removed during the pre-processing of the signals, for further analysis. Unprocessed ultrasonic welding defect signals, which contain noise, are not easily identified for the type and pattern of flaws they contain. Especially with TOFD welding defect signals which is often mixed with noise, distinction between grain noise and small flaws is not always easy. Presence of larger grain noise makes it difficult to interpret the defect result and noise. Thus, it is of great importance to de-noise the ultrasonic welding defect signal before classification of defect is carried out. This paper mainly focuses on the use of wavelet packet method using Stein’s Unbiased Estimation of Risk(SURE) to de-noise the TOFD welding defect signals and the results has been compared with that of Split Spectrum Processing (SSP) with Polarity Thresholding algorithm (PT) for de-noising of the same.

Abstract	Rapid change in business environment have compelled the world class organizations to implement integrated software solution to all their functional processes, the most typical solution is ERP. For this, organizations are striving to hire ERP consultants to line up their resources. However, it is evident from literature that organizations spend a lot of resources on hiring consultants. Likewise, Saudi Companies are also implementing ERP systems for the same purpose and thereby hiring ERP consultants. However, the role of hiring consultants is also crucial in Saudi Companies and they are spending plenty of resources on them. In this paper we have investigated the roles, characteristics, responsibilities, scope of work and identify the reasons for and against hiring ERP consultants specifically in Saudi Arabia. No study has been conducted to investigate the consultants’ roles in such systems in Saudi Arabia.

Abstract	We present a new query formulation interface called FFQI (Fast Formulation Query Interface) which is based on a semantic graph model. The query formulator allows the users with limited IT skills to query and explore the data source easily and efficiently. Here the user inputs are formulated based on the graph search algorithm by using the probabilistic popularity measure. The query ambiguity has been resolved through the ranking technique. We formulated the SELECT-PROJECT-JOIN queries using the aggregate functions. In additional to that we also implemented a formulation technique for image databases. Thus this interface allows user to interact with relational graph-type databases in an effective and easier way.

Abstract	The purpose of this study is to examine information security culture among and to investigate the factors that contribute to the information security culture among ICT librarians. The study uses the quantitative research method to analyze the responses to open-ended questions by 56 ICT librarians in private colleges. An empirical study is presented of an information security culture assessment instrument, which is a questionnaire, thereby providing a valid and reliable tool that can be used by organizations (libraries) to assess the in-house level of the information security culture. The evidence suggests that principles significantly influence the information security culture among ICT librarians. The developed statements in the information security culture assessment instrument are not categorized to be answered by different audiences in an organization. This could be useful as not all employees would, for instance, be in a position to answer management and strategic questions. Practitioners should understand the factors influencing the information security culture in order to develop a good culture and at the same time to protect their information assets in organization.
