Increasing urban green and blue structure is often pointed out to be critical for sustainable development and climate change adaptation, which has led to the rapid expansion of greening activities in cities throughout the world. This process is likely to have a direct impact on the citizens' quality of life and public health. However, alongside numerous benefits, green and blue infrastructure a...

Data from the 2010 Learners' Perceptions Survey (LPS) administered through the Office of Academic Affiliations, Department of Veterans Affairs (VA) were analyzed to identify factors associated with dental residents' satisfaction with the VA as a clinical training environment. Satisfaction scores were linked to clinic workloads, dental procedure complexity levels, staffing patterns, and facility...

Activity-based accessibility measures, describing the level of access to spatially distributed activities, are not put to the same use in land use and/or transport policy evaluations as are infrastructure-based accessibility measures, which describe congestion levels or the average speed on the motorway network. In this paper we attempt to improve the current evaluation practice by the applicat...

Application-level peer-to-peer (P2P) network overlays are an emerging paradigm that facilitates decentralization and flexibility in the scalable deployment of applications such as group communication, content delivery, and data sharing. However the construction of the overlay graph topology optimized for low latency, low link and node stress and lookup performance is still an open problem. We p...

Trajectory data are normally generated as sample points, which are very difficult to understand and to analyze because they are often collected with no semantic information. Several studies have been developed for trajectory data analysis. Recently, a new model was designed to reason over trajectories as stops and moves, where stops are the important parts of trajectories. Based on this work, d...

As the disfunctions of the information society and social development progress, intrusion problems such as malicious replies, spam mail, private information leakage, phishing, and pharming, and side effects such as the spread of unwholesome information and privacy invasion are becoming serious social problems. Illegal access to information is also becoming a problem as the exchange and sharing ...

This paper reports on current work within our project MONTANA which is a digital media archive for teaching and research. We show how to model structures and describe metadata by the use of XML. We combine the Resource Description Framework, which is an application of XML, with the Dublin Core to provide broad interoperability and data reuse. Our approach models metadata of single objects as we...

TRENCADIS is a Grid infrastructure to store and to process large amounts of medical images and its associated data in DICOM objects. This system enables radiologists to effectively group, search and manipulate images and structured reports in order to relate clinical findings and to be of practical value in the diagnosis and treatment of diseases. The paper presents a new platform for the deplo...
