A stage hypothesis for information centers (ICs) is proposed and 26 critical success factors (CSFs) for IC managers are investigated. Based on 311 responses from IC managers, support is found for the proposed stages and information is provided about the importance of the CSFs. A principal components analysis is performed on the 26 CSFs which identifies five composite CSFs: (1) commitment to the...

End-user programming becomes increasingly important for context-aware computing since the system behavior of existing context-aware systems does not reflect the situation the end-user intended. In this paper, we present a general proposed framework, which enables end-users to program, customize and control context-aware system behavior in a simple way. We discuss the building prototypes and con...

In this paper we present the FolksoDriven Cloud (FDC) built on Cloud and on Semantic technologies. Cloud computing has emerged in these recent years as the new paradigm for the provision of on-demand distributed computing resources. Semantic Web can be used for relationship between different data and descriptions of services to annotate provenance of repositories on ontologies. The FDC service ...

Cloud computing permits the end user to access the required software or hardware structures on demand. This will reduce the cost of installation and maintenance. Mobile Cloud Computing (MCC) is introduced to increase the experience of end user by providing them the services at best. The development of cloud computing and virtualization techniques, enables smart phones to overcome the resource l...

The new era of computing called Cloud Computing allows the user to access the cloud services dynamically over the Internet wherever and whenever needed. Cloud consists of data and resources; and the cloud services include the delivery of software, infrastructure, applications, and storage over the Internet based on user demand through Internet. In short, cloud computing is a business and econom...

The end user service development known as the user-centric SOA emerged as a new approach that allows giving the end user the ability to create on the fly his own applications that meet a situational need. In fact, the classical SOA was designed for developers and is characterized by a heavy technical stack which is out of reach of end users. The user-centric SOA approach brings great added valu...

In the platform age, copyright protected contents are primarily disseminated over internet. This model poses various challenges to regime that was mainly designed in and for analogue age. One of these is related fair balance between interests rightholders other members society. Copyright norms try guarantee this by granting a high level protection preserving some flexibility end-users. The pres...

The purpose of this study is to revise and revalidate the End-User Computing Satisfaction (EUCS) instrument to measure satisfaction with a Web site from a usability perspective. This study is especially important given the increased significance of the Web and the uniqueness of the Web as a computing environment. A total of 176 students participated in a lab simulation that involved a usability...

This paper describes an approach for enabling remote database access from heterogeneous thin clients. DataX is a proxy-based architecture that supports disconnected operation by replicating a subset of the database on the mobile client, using a weak consistency criterion. It adapts data replication to device characteristics, link attributes and user preferences. It employs a per-device renderer...

Embedded systems that require high performance hardware for signal processing, optimization, and control have historically relied on optimized fixed-point algorithms deployed on low-power microprocessors and/or digital signal processors. However, the sensing and actuation interfaces in such systems increasingly rely on oversampled, single-bit sigma-deltamodulated (SDM) representations of data i...
