MOTIVATION The online resources in the life sciences are characterized by a great fragmentation and one of the pressing issues of bioinformatics is making the integration of these resources a smoother and more flexible process than it is currently. Here we present i-cite, a browser extension, which implements a client-side model of integration which improves the navigation within the rapidly in...

In this paper we present a search problem in which mobile agents are searching for static resources. Each agent wants to obtain exactly one resource. Both agents and resources are spatially located on a road network and the movement of the agents is constrained to the road network. This problem applies to various transportation applications including: vehicles (agents) searching for parking (re...

A geo-located evaluation method for the integration of road projects in territories andthe choice of variantsBased on the advanced technique and science in the domains of the geographic informationand the social and environmental indicators, the objective of this thesis is to contribute to thedevelopment of a tool for helping the road variants identification and evaluation.<...

Landscapes will likely become increasingly fragmented for biological organisms and ecological processes as the human population and its demands for resources continue to escalate. Landscape fragmentation results in habitat loss and alterations in the composition and spatial arrangement of landscape elements, consequently affecting population and ecosystem processes. Thus, to protect biodiversit...

Wildlife-vehicle collisions (WVC) have increased and now there is a world-wide problem related to significant mortality of wildlife, habitat fragmentation, change in behavior and even disappearance of local endangered populations. Along with these deleterious effects on wildlife, WVC can also result in injuries and deaths of humans. During the three-year monitoring, a total of 7,495 wildlife-ve...

The long production cycle and huge cost of collecting road network data often leave the data lagging behind the latest real conditions. However, this situation is rapidly changing as the positioning techniques ubiquitously used in mobile devices are gradually being implemented in road network research and applications. Currently, the predominant approaches infer road networks from mobile locati...

EEcient utilization of processing resources in a large, multiuser parallel computer depends on processor allocation algorithms that minimize system fragmentation. We propose three processor allocation algorithms for the k-ary n-cube class of parallel architectures, which includes the hypercube and multidi-mensional torus. The k-ary Partner strategy is a conventional contiguous processor allocat...

Roads threaten animal species through habitat loss, fragmentation and degradation, direct mortality. It is crucial to understand how respond linear infrastructure for effective conservation of communities in fragmented landscapes. We assessed relationships between amphibian abundance roads/ railways fragmentation. examined whether the combined effects loss roads or (accessible habitat) was a be...
