Grid portals typically store user grid credentials in a credential repository. Credential repositories allow users to access Grid portals from any machine having a Web browser, but their usage requires several authentication steps. Current portals require users to explicitly go through these steps, thereby hindering their usability. In this paper we present intuitive and easy to use tools to ma...

Portals providing the modeling of social relations among people became more and more popular. Although the existing FOAF (Friend of the Friend) ontology developed for modeling such social relations was introduced and enjoyed popularity, it is not used in such extent that it can be considered as World Wide Social Network. Such network can bring benefits (e.g., by providing useful analysis) only ...

E-government is a field where oriented practice is considered crucial for its prosperity. Therefore, best practices are considered among the success factors of e-government portals. To this end, e-government maturity models can be used to provide guidance and guidelines to identify those best practices. After an extensive literature review, we have collected both; the e-government portals’ best...

This paper predicts the malicious object prone site from the set of multi business portals of an organization or company. Graph theory is used to solve this problem as the diverted traffic of customers is interdependent among all the business portals. At first the interconnected business portals are represented in the form of a graph and its corresponding adjacency matrix. Later the centrality ...

Direct posterior and posterolateral portals are the standard portals used in posterior elbow arthroscopy. A posteromedial portal in the elbow is not recommended because of its proximity to the ulnar nerve. However, iatrogenic injuries to the ulnar nerve have been reported after elbow arthroscopy using the standard posterior portals, especially in posteromedial elbow joint pathologies. We presen...

In general, portals are regarded as gateways to networked information and services, facilitating access to other related sites. Typically, portals provide transparent one-stop access to functionalities needed in a common context and make these appear as a single integrated application. Although these functionalities are implemented and made available by heterogeneous applications, they are inte...

Behavioral researchers are increasingly using Web-based software such as JavaScript to conduct response time experiments. Although there has been some research on the accuracy and reliability of response time measurements collected using JavaScript, it remains unclear how well this method performs relative to standard laboratory software in psychologically relevant experimental manipulations. H...
