Title:	FULL RELATIONSHIP AMONG E-SATISFACTION, E-TRUST, E-SERVICE QUALITY, AND E-LOYALTY: THE CASE OF IRAN E-BANKING
Author:	SOHEILA GHANE, M. FATHIAN, M. R. GHOLAMIAN
Source:	Journal of Theoretical and Applied Information Technology pp 01 - 06 Vol 33. No. 1 -- 2011
Abstract	Customer e-loyalty is an important issue in the very competitive environment of e-banking. Different studies show that e-loyalty is influenced by e-satisfaction, e-trust and e-service quality. However, little attention has been given in the literature to fully understand the full relationships among them. The purpose of this study is to empirically investigate the impacts of e-satisfaction, e-trust and e-service quality on e-loyalty, in e-banking as an aspect of B2C e-commerce context. Data was collected to test the model from faculties and students of Tehran universities as respondents, and empirical analyses were performed using SEM. The analytical results indicate that although service quality, e-satisfaction, and e-trust have strong direct effect on e-loyalty, impacts of indirect effects (with e-satisfaction and e-trust playing mediating roles) are more significant. Additionally, this study represents a framework that indicates the full relationship among the three factors and their (direct and indirect) effects on e-loyalty, a phenomenon that has not previously been explored.
Keywords	E-Satisfaction, E-Service Quality, E-Loyalty, Relationship, E-Banking, IRAN

Title:	A TASKS ALLOCATION ALGORITHM FOR DISTRIBUTED SYSTEMS
Author:	MOSTAPH ZBAKH, MOHAMED DAFIR EL KETTANI
Source:	Journal of Theoretical and Applied Information Technology pp 15 - 21 Vol 33. No. 1 -- 2011
Abstract	In this paper, we complete and implement the general problem of tasks allocation. The theoretical part of this work is developed in our previous work [14] and here we focus our research on the practical aspect. The problem is modelled as a non-cooperative game between several players. For this game, we adopt the Nash equilibrium structure and on the basis of this structure, we draw a distributed tasks allocation algorithm that can find this equilibrium. We implement this algorithm by using the MPI environment and a system of 10 computer sources that generate the tasks and 10 processing computers. The theoretical and numerical results show that the tasks allocation strategy obtained leads to a good load balancing of computers

Title:	COMPARISON OF PULSED ELECTRIC FIELD GENERATION TECHNIQUES FOR MICROBIAL INACTIVATION APPLICATION
Author:	HANIFAH JAMBARI, NAZIHA AHMAD AZLI, MOHAMED AFENDI MOHAMED PIAH

Abstract	This paper presents a comparative study on various pulsed electric field (PEF) techniques for liquid food sterilization applications. Pulsed Electric Field (PEF) is an alternative method compared to the conventional food pasteurization method in removing harmful bacteria contained in liquid food products. A Cascaded Multilevel Inverter (CHMI) is proposed as a PEF generator to produce a higher output voltage without using a transformer to inactivate microbial in liquid food. It will reduce the power losses of the system while yielding better sterilization effectiveness as well as reduce cost. The CHMI has been simulated using MATLAB/Simulink software to analyze the performance of the circuit. The simulation results demonstrate that the CHMI can produce both bipolar and unipolar square wave output pulses. This in turn contributes to the flexibility of the CHMI in testing the effectiveness of the PEF produced on liquid food sterilization compared to the conventional method and other power electronics circuits that have been used for similar application.

Title:	SHARP-EDGES METHOD IN ARABIC TEXT STEGANOGRAPHY
Author:	NUUR ALIFAH ROSLAN, RAMLAN MAHMOD, NUR IZURA UDZIR
Source:	Journal of Theoretical and Applied Information Technology pp 32 - 41 Vol 33. No. 1 -- 2011
Abstract	One of the issues that arise in the text steganography is the capacity of hiding secret bit. Focusing in Arabic text steganography we propose a sharp-edges method to encounter the issue. This new method will hide the secret bits in the sharp-edges for each character in the Arabic text document. The main processes involved are identifying sharp-edges in the cover-text, secret message preparation to be hidden as a binary string and lastly, the bit hiding process. The experiments show that the capacity percentage used to hide the secret bit was increased up to 37.8%, resolving the capacity issue. The stego-text for this method has high invisibility, and therefore it is possible to be published publicly. We introduce keys to determine the possition of the secret bit randomly. This method utilizes the advantages of the Arabic text for steganography and can also be implemented to the same text scripting of languages such as Jawi, Persian or Urdu.
Keywords	Steganography, Text Steganograpy, Arabic Text Steganography, Arabic Character, Sharp-Edges.

Abstract	The Internet or distributed computing has evolved from a simple file sharing mechanism to data source sharing and dynamic services. This evolution has made data source sharing an urgent necessity at the present time. Therefore, we should benefit from distributed data sources that are spread across a network and address current data sharing challenges, which include masking the heterogeneity between data sources, and between disparate clients and different communication protocols and formats. In the recent past, efforts have been made by researchers and private companies to propose approaches for accessing remote, heterogeneous and autonomous data sources to share them across a network. Other efforts are looking at these approaches and concepts with the aim of developing applications in both centralized and decentralized environments to provide uniform access to and sharing of data sources. In this paper, we review four data sharing approaches that have been proposed, namely Transaction Processing Monitors, Tuplespace, Resource Description Framework and Data Service Approach. For each approach, we will present its architecture, limitations and problems, as well as applications that have been developed based on its concepts. Moreover, the most important open problems related to datasharing systems are briefly highlighted.
Keywords	Data Sources, Data Sharing Approaches, Transaction Processing Monitor, Tuplespace, Resource Description Framework, Data Service Approach, Open-Source Applications, Proprietary Applications.

Title:	USERS EXPECTATIONS FEEDBACK CONSISTENCY AS A FIRST STEP FOR A BETTER DATA QUALITY
Author:	L. BRADJI , M. BOUFAIDA
Source:	Journal of Theoretical and Applied Information Technology pp 58 - 68 Vol 33. No. 1 -- 2011
Abstract	User feedback is a new direction employed to assist users in building data integration systems and to improve their quality. We claim that the first step to the efficient data quality improvement in a data integration system is the consistency of user’s expectations feedback because user(s) can have multiple expectations of the quality of the value and the content of the query results at the same time. Therefore, in this paper we propose an approach that allows one to detect user’s expectations quality problems, especially inconsistency, and so their improvement before their use for determining the data quality issues at the data sources in the second step. This approach takes a set of queries from the log file and the user’s expectations relative to the results of each query to identify and prioritize the inconsistencies of user’s expectations values. Thus, to accomplish this, three algorithms are proposed. The first algorithm manages the user’s expectations inconsistency related to the same query. The second algorithm divides queries into groups of similar attributes by using the clustering technique of data mining. As the rerun of the queries is time consuming, the approach takes samples of data to determine the queries results interactions. The quality of these samples is determined in advance in order to ensuring the correctness of queries results interactions. The third algorithm takes both the queries results interactions and the user’s expectations to address the inconsistency between the user’s expectations of queries results interactions. To detect the user’s expectations inconsistencies, we have established a set of user’s expectations axioms and inference rules, which are used by the algorithm to deduce an automatic expectation value. This algorithm introduces a solution, which is inspired from the axioms systems of Logic, to solve the inconsistency.

Abstract	Island model deals with a species which is subdivided into a number of discrete finite populations, races or subspecies, between which some migration process occurs. If the number of populations is small, an assumption of equal rates of migration between each pair of populations may be reasonable approximation. In this paper we shown a general solution is given for the process of population divergence under this model following subdivision of a single parental population, expressed in terms of the observed average frequency of cells and explains how to find a zone in an image that is representative and small enough to optimize the later analysis of the image in general whether manual or automatic. This diagnostic method will analyze the behavior of a group of special cells (could be Cancer)

Abstract	Since cutting conditions have an influence on reducing the production cost and time of machining process and also the quality of a final product the prediction of output machining parameters such as surface roughness and tool life criteria for different cutting speed, feed rate, depth of cut and tool geometry is one of vital modules in process planning of metal parts. In this study with use of experimental results on machining of ST-37 and subsequently, ANFIS system, importance of each parameter was studied. These parameters were considered as input in order to predict the surface finish and tool life criteria, two conflicting objectives, as the process performance. In this paper ANFIS system was applied to predict output parameters of machining. Results show that amount of input influence on the outputs parameters. By using ANFIS input parameters entered to ANFIS system then all training data was trained with 300 epochs. After training the value of error which is 1.039e−006 was calculated.

Title:	APPLYING ISM AND ANN TECHNIQUES IN THE DEVELOPMENT OF USER EXPECTED COMMAND LOCATION PREDICTING APPROACH
Author:	CHUNWEI CHEN
Source:	Journal of Theoretical and Applied Information Technology pp 93 - 103 Vol 33. No. 1 -- 2011
Abstract	The purpose of this research is to develop a method for obtaining information on user’s expected command location and to verify its effectiveness in improving the inconsistency between the command locations of the software application tools and those expected by the users. This method proposed in this research is called User Expected Command Location Predicting Approach (UECLPA). It is defined as an approach to deconstructing user’s expected idea of the command location and transform it directly to a treelike command element structure. This forecast method for user’s idea of the command location is characterized with real-time modification of the predicting results of user’s command locations. These two features are achieved by Interpretive Structural Modeling (ISM) and Artificial Neural Network (ANN). In terms of command locations, the inconsistency problem between the software application tools and the user’s expectation is quite common in current software application tools. This often causes the users to have bad impressions on the product or even affect the success of the product. The interface designers should pay attention to this problem. In this study, users were invited to operate the old and new interfaces of a software application tool to verify the effectiveness of UECLPA. Results from the experiment indicated that there did exist differences between users and designers in the command location of software application tools. Moreover, UECLPA proposed in this study proved effective in improving the inconsistency problem between user’s expectation and the ready-made command location in the software application tool. Therefore, it is, suggested that before organizing the command locations of software application tools, the interface designers should understand the users’ ideas and demands. Last but not least, the application of UECLPA in the planning of command locations in software application tools will help decrease the inconsistency problem of software application tools.

Abstract	This paper proposes a new method for the detection of glaucoma using fundus image which mainly affects the optic disc by increasing the cup size is proposed. The ratio of the optic cup to disc (CDR) in retinal fundus images is one of the primary physiological parameter for the diagnosis of glaucoma. The K-means clustering technique is recursively applied to extract the optic disc and optic cup region and an elliptical fitting technique is applied to find the CDR values. The blood vessels in the optic disc region are detected by using local entropy thresholding approach. The ratio of area of blood vessels in the inferior-superior side to area of blood vessels in the nasal-temporal side (ISNT) is combined with the CDR for the classification of fundus image as normal or glaucoma by using K-Nearest neighbor , Support Vector Machine and Bayes classifier. A batch of 36 retinal images obtained from the Aravind Eye Hospital, Madurai, Tamilnadu, India is used to assess the performance of the proposed system and a classification rate of 95% is achieved.

Abstract	Wi-Fi, a Wireless Local Area Network technology has solely conquered the arena of short range wireless broadband systems. To support the existing system and to further enhance the measure of performance in multipath fading environment, Wi-Fi technology is intertwined with space diversity technique which is implemented using Alamouti coding and is then introduced with interleaving/scrambling technique to take the benefit of time diversity. Diversity technique has been an essential factor in improving the quality of the wireless system’s operation by providing performance almost equivalent to that of the least distorted path among various multi paths at any given time and thereby accounting for the fading effect caused in corruptive communication channels. This paper discusses the performance of space diversity techniques in Wi-Fi by comparing their Bit Error Rate (BER). Various channel models are taken into account to simulate the real time scenario of a noisy unreliable wireless environment.

Abstract	There has been a significant growth in Internet shopping over the last few years in Iran. However, there is a little awareness of the effective factors which attract consumers to purchase online. It has been predicted that the city of Isfahan in Iran will experience a sharp increase in the Internet usage in the next decade. However, the factors affect the local e- shopping of different types of products and the demographic characteristics of the local Internet consumers have received a little direct research so far. The present study aims to consider the effective factors on consumer e-shopping behavior and the role of each personal characteristic on these factors for different types of products. The data were obtained from 412 volunteers who have had the Internet shopping experience, and were analyzed using MLP neural networks and logistic regression per product. Then, after comparing the accuracy of these methods, the most essential factors which motivate the consumers to buy online were determined by a trained neural network. Finally, a regression analysis was performed to assess the significant difference between variables of each demographic characteristic per factor.
