This work aims to provide administrators with services for managing permissions in a distributed object system, by connecting business-level tasks to access controls on low level functions. Specifically, the techniques connect abilities (to complete externallyinvoked functions) to the access controls on individual functions, across all servers. Our main results are the problem formalization, pl...

Wireless Sensor Network (WSN) is consisting of independent and distributed sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. However, the limited resources of sensors and hostile environments in which they could be deployed, make this type of networks vulnerable to several types of attacks similar to those occurring in ad hoc networks. The most ...

The Maltese government has instigated its vision of an ‘e’ infrastructure to support the islands’ Small and Medium sized Enterprises (SMEs) in their efforts to meet the challenges of the new unbounded digital economy. This paper takes an early look at the perception of ‘e’ potentials amongst Maltese entrepreneurs. Although the findings depicted a generally positive attitude towards the concept ...

Accessibility of high-throughput genotyping technology makes possible genome-wide association studies for common complex diseases. When dealing with common diseases, it is necessary to search and analyze multiple independent causes resulted from interactions of multiple genes scattered over the entire genome. This becomes computationally challenging since interaction even of pairs gene variatio...

Many object-oriented software applications contain implicit business rules. Although there exist many approaches that advocate the separation of rules, the rules’ connections still crosscut the core application functionality, which impedes reuse, either anticipated or not. Moreover, ultimately business rules are implemented in a programming language, which decreases understandability and access...

The French health care system was ranked number one by the World Health Organization in 2000 due in large part to its high level of population health, degree of freedom for physicians and patients, easy access to health care for most people, absence of waiting lists for treatment and universal coverage. It changed considerably with the Juppé reform of 1996, which shifted power from the health i...

In ad hoc networks, since network division occurs frequently, it is effective to replicate data items. This paper proposes effective replica allocation methods in ad hoc networks where each data item is updated at irregular intervals. The proposed methods allocate replicas based on probability density functions of the update intervals of data items. Also, they invalidate replicas that have been...

Vehicular Sensor Networks (VSNs) are an emerging network paradigm, suitable for various applications in smart-intelligent-vehicular network making use of vehicles’ sensors as data sources and Inter-Vehicle Communication systems for the transmissions. The main issues in VSNs reside in the data harvesting and its dissemination in such a large-scale network, characterized by the frequent topology ...

Before the computer age, games were played in the physical world where players would have to interact with real objects and each other, triggering a series of emotions. Nowadays, the computer games have become one of the most popular forms of entertainment due to their high-level of attraction and accessibility. However, the game industry is always trying to find new ways of making games more i...
