Ranking of universities regarding their web-based activities plays a pivotal role in promoting scientific advancement since it motivates the open access accessibility to scientific results. In this study, a new ranking system based on the website quality factors and traffic evaluation was proposed. Since top-ranked universities are usually considered as the standard models for lower ranked ones, the focus of this study was on top-ranked universities. The proposed ranking was compared with well-known Webometrics ranking system. The website traffic and quality assessment were acquired for websites of top-ranked world universities and the correlation between these indices and the Webometrics ranking was evaluated. The summation of the weighted value of obtained measures according to an optimal weight vector obtained by a genetic algorithm framework was used for ranking purposes. The results showed that the website total traffic size was correlated with Webometrics rank (R≈-0.6, p< 0.01). Also, using the weighted value of website quality and traffic measures, the proposed ranking system could predict Webometrics ranking by the accuracy of up to 69%. Even though the method was proposed for universities, it could be applied for ranking other types of centers or companies, provided that the suitable cost function for the genetics algorithm framework was defined.

The problem of image signal processing in the information system with adaptive antenna array based on the inversion of sample estimates of correlation matrix of observations is considered. The example of the maximum signal-to-noise ratio criterion shows the problem, inherent in classical methods of finding the optimal weight vector under a priori uncertainty conditions when detecting correlated image signals. It has been concluded that the dependence of these methods on the inverse of estimation of the correlation matrix of observations leads to the impossibility of separating correlated image signals. As a consequence, the use of classical methods of finding the optimal weight vector in the information system with adaptive antenna array is effective only in the case of image restoration from a single signal source, with the signal received on the set of independent jamming background. A novel method, invariant to the correlation of image signals, has been developed for finding the optimal weight vector without the usage of correlation matrix of observations. An image restoration algorithm invariant to correlation of image signals in the information system with adaptive antenna array is proposed. Statistical models have been constructed for the classical method based on the criterion of maximum signal-to-noise ratio and invariant to correlation method of image restoration in following cases: a single source against the jamming background of two independent sources; two independent sources against the jamming background. Simulation results in the information system with adaptive antenna array are presented, showing to visually assess efficiency of proposed methods of image signal restoration using optimal weight vector. Detailed analysis of the results obtained is carried out.

In this article, it is tried to study the role of IT powerful tools to change in identity of procedure in developmental project management from traditional space to virtual space (conversion of project traditional management to project electronic project) and also it is studied how to enforce electronic methods in managing projects and it’s effect on expense/time and quality factors with modeling a developmental project as a pilot project to exiting systems and procedures in projects. Since in accordance to PMBOK [6] viewpoint, project management process can be defined as management on multiple domains such as Communication, Provisions, Cost, Quality and time. Therefore, in this article, some suggestive algorithms will be introduced to show the feasibility of virtual making and web-based management of one of the domains of project management. (Cost domain)

AbstractOnline shopping has become popular over the years and is a widely used way to purchase goods and services. For online retailers to succeed, it is important that they have a quality website to attract and retain customers. The aim of this study was to investigate the construct validity of three respective measurement instruments related to website quality factors, namely; system, information and service quality factors, which may influence consumers within the online shopping environment in a South African context. Primary data was collected through self-administered questionnaires. The demographic and online shopping profile of the sample are presented and followed by confirmatory and exploratory factors analyses on the three instruments. The confirmatory factor analysis found poor fit for the original hypothesised models for each of the scales; further exploratory factor analyses revealed slightly different dimensionalities underlying the scales, yet these were still somewhat aligned with the theoretical framework from which the original scales were derived. Despite this, the study provides a platform for future revision of the scales and future research into website quality factors within the online shopping environment in a South African context.

Today, manufacturing industry is characterized by globalization, unpredictability and rapid change. To be competitive, companies are globally outsourcing activities that are outside their core competencies. In this context, online marketplaces for manufacturing services have become attractive venues for developing supply chain relationships. Despite their significant growth within last few years, online markets are still in their infancy phase. One of the underdeveloped areas in such markets is supply and demand representation. This paper reflects the result of a survey on the existing online markets in the manufacturing industry. Particular focus of this survey is on identifying the major criteria used by market administrators and users for describing supply and demand. Findings of this survey can provide preliminary data for future efforts in development of standard models for conceptualization and representation of supply and demand in online markets.

Website is a necessity for organizations to enable users worldwide to access their information and gain a competitive edge over others. The diversity of websites makes assessing website quality a difficult task. The aim of this paper is to identify the issues faced in the quality evaluation of university websites, the models and the factors used for evaluating university website quality. Systematic literature review was used to identify and synthesize related scholarly research papers. Findings show that there is a lack of study on university website quality compared to business websites; website designers did not have the appropriate knowledge on the interface design; and the website quality evaluation is complex since there is no specific evaluation model. Webqual 4.0 model was used to evaluate the quality of universities' websites. From 24 studies, initially 79 quality factors were extracted. After performing comparison, filtration and memoing, six quality factors were identified: information quality, specific content, usability, web appearance, service interaction quality, and functionality. This study makes a useful contribution in developing university website quality model by extending the Webqual 4.0 model.

In the future generation, computer science plays prominent role in the scientific research. The development in the field of computers will leads to the research benefits of scientific community for sharing data, service computing, building the frameworks and many more. E-Science is the active extending field in the world by the increase data and tools. The proposed work discusses the use of semantic web applications for identifying the components in the development of scientific workflows. The main objective of the proposed work is to develop the framework which assists the scientific community to test and deploy the scientific experiments with the help of ontologies, service repositories, web services and scientific workflows. The framework which aims to sustenance the scientific results and management of applications related to the specific domain. The overall goal of this research is to automate the use of semantic web services, generate the workflows, manage the search services, manage the ontologies by considering the web service composition.
