Cloud Computing has become mainstream technology offering a commoditized approach to software, platform and infrastructure as a service over the Internet on a global scale. This raises important new security issues beyond traditional perimeter based approaches. This paper attempts to identify these issues and their corresponding challenges, proposing to use risk and Service Level...

When scientists or engineers are looking for information in document collections, or on the web, they generally have a precise ob jec- tive in mind. Instead of looking for documents ”about a topic T ”, they rather try to answer specific needs such as finding the definition of a con- cept, finding results for a particular problem, checking whether an idea has already been tested, or...

Models, which represent in 3 dimensions the geometric elements of a city, are called 3D city models. Those models are used for an intended wide range of applications beyond mere visualization. Such uses are made possible by enriching the geometrical aspects with urban or environmental data that cannot be perceptible to a user without a visual abstraction. Using such models implies...

Background: Mental health has long been a neglected problem in global healthcare. The social and economic impacts of conditions affecting the mind are still underestimated. However, in recent years it is becoming more apparent that mental disorders are a growing global concern and there is a necessity of developing novel services and researching effective means of providing...

In this paper, based on the Mobile Data Challenge data obtained from the Lausanne data collection campaign, our research aims first to derive network connectivity (e.g., WLAN, 3G) and its Quality of Service (QoS) and mobility patterns of the mobile users, as this connectivity and QoS relate to the user's application activity. Second, we aim to understand how these patterns...

Mobile (smart)phones prevail in our daily life activities, and in our research we aim for it to provide pervasive services for wellness. Therefore, we assess the phone's feasibility to unobtrusively, continuously and in real-time track its user's physical activity and the resulting energy expenditure (EE). Activity Level Estimator (ALE) is an Android OS application...
