In railways systems the timetable is typically represented as a weighted digraph on which itinerary queries are answered by shortest path algorithms, usually running Dijkstra’s algorithm. Due to the continuously growing size of real-world graphs, there is a constant need for faster algorithms and many techniques have been devised to heuristically speed up Dijkstra’s algorithm. One of these tech...
content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....
Remote sensing and GIS approaches have provided valuable information on modeling water resources, particularly in arid regions. The Sahara of North Africa, which is one the driest regions Earth, experienced several pluvial conditions past that could stored significant amounts groundwater. Thus, harvesting by revealing groundwater prospective zones (GWPZs) highly important to security management...
Water shortage is a common phenomenon in many parts of Kenya the dry season, including Kapseret Sub-County. However, water harvesting has seldom been practised, despite its high potential to alleviate shortages season. This largely influenced by lack access dams and pans. The objective this study was identify dam sites for Sub County, Uasin Gishu Kenya. Multiple criteria analysis weighted overl...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
BACKGROUND AND AIMS Extracted-overlay fusion imaging is a novel computed tomography/magnetic resonance-ultrasonography (CT/MR-US) imaging technique in which a target tumor with a virtual ablative margin is extracted from CT/MR volume data and synchronously overlaid on US images. We investigated the applicability of the technique to intraoperative evaluation of radiofrequency ablation (RFA) for ...
The standard MR protocol of the spine included sagittal T1weighted and T2-weighted fast spin echo. Volume measurements are made by using a transparent template to overlay a grid of regularly spaced points over MRI scans of randomly selected patients (Figure 1). This point is counted as the full contact of the counter. Counts are made three times. The double or middle number is used. The volume ...
Skull-face overlay is the most time-consuming and error-prone stage in craniofacial superimposition, an important skeleton-based forensic identification technique. This task focuses on achieving the best possible overlay of an unknown skull found and a single ante-mortem image of a candidate missing person. The process is influenced by some sources of uncertainty since two objects of different ...
