This dissertation investigates algorithmic techniques for temporal process discovery in many domains. Many different formalisms have been proposed for modeling temporal processes such as motifs, dynamic Bayesian networks and partial orders, but the direct inference of such models from data has...

One of the dominant properties of a global computing network is the incomplete information available to principals about each other. This was the motivation of using the notion of probabilistic trust as an approach to security sensitive decision making in modern open and global computing...

The double auction, a highly efficient market mechanism, has been widely used by both traditional and online exchanges. However, with the globalisation of the economy, these marketplaces increasingly need to compete with each other to attract traders and charge suitable fees to make profits. In...

Egypt is investing in e-services as a driver for socioeconomic development. Designing e-services that are conducive to novice users is central to their proliferation. This paper presents a study in an Egyptian government organization to investigate novice user perception of e-services, based on...

The introduction of mobile communications has undoubtedly altered our physical and social world. Like the Internet, it has changed the way we interact with each other allowing for communication using a variety of communication mediums by means of a magnitude of interactive mobile devices. The...

During the last 10 years Internet use has dramatically increased, causing organizations to become increasingly concerned aware both their need to ensure the security of their information and of its vulnerability. At the same time, the fast proliferation of systems and their respective...

This study examines how the infrastructure requirements of cloud computing affect the design of data center network components. The global market for cloud computing is projected to grow by over 20% (CAGR) over the next five years; infrastructure for cloud computing is expected to be a $60B...

Existing constructs for privacy concerns and behaviors do not adequately model deviations between user attitudes and stated user behaviors. While a number of studies have examined supposed deviations from rationality by online users, the true explanations for these stated behaviors may lie in...
