Introduction The American Heart Association has deemed the quantification of cerebral perfusion in stroke to be of paramount importance. Fast, accurate and automated determination of perfusion image maps is essential for analyzing tissue at risk after an ischemic stroke event [1,2]. The need for offline post-processing of Dynamic Susceptibility Contrast (DSC) images can delay the availability o...

BACKGROUND Health professionals and authorities strive to cope with heterogeneous data, services, and statistical models to support decision making on public health. Sophisticated analysis and distributed processing capabilities over geocoded epidemiological data are seen as driving factors to speed up control and decision making in these health risk situations. In this context, recent Web tech...

Map building is one of the most popular classical problems in mobile robotics field and sensor model is the way to interpret raw sensory information in spatial world especially for building map. For mobile robots, working in indoor environment, Ultrasonic Sonar(US) is famous because of its availability, wide angle and long range sensing ability etc, in spite of some problems. Among them, Specul...

Compared to surface water, groundwater resources are the primary source of water supply in arid and semi-arid regions of Iran, hence the importance of the management of these resources .  In this regard, we assessed the effects of landuse changes on the qualitative and quantitative status of groundwater resources in Eshtehard region, Iran. Through processing and analyzing the satellite images, ...

The wealth of satellite imagery [1] available in web mapping service applications such as Google Maps, which now provides high-resolution satellite images from many locations around the Earth, has opened the appealing perspective of performing classification and retrieval tasks via programming libraries such as SwingX-WS. In fact, the introduction of Google’s mapping engine prompted a worldwide...

Forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. Traditional methods such as field surveys are almost time-consuming and cost-intensive. Improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. This research co...

Unitary transformations are the most general input-output maps available in closed quantum systems. Good control protocols have been developed for qubits, but questions remain about the use of optimal control theory to design unitary maps in high-dimensional Hilbert spaces, and about the feasibility of their robust implementation in the laboratory. Here we design and implement unitary maps in a...

This article begins with a brief historical account of our attempts to understand the brain by endlessly mapping out discrete structural and functional territories. These territorial or classical maps are then contrasted with the new metabolic maps, which show brain function and plasticity as it has never been conceptualized or visualized before. The new maps, along with more recent research in...

In this paper we propose utilizing of topic maps as an integration tool for Connexions1 content aiming at creating more subject-oriented, knowledgebased ways of connecting resources in the Connexions repository. We discuss to what extent and how open content, including metadata, may be extracted from Connexions e-learning modules and mapped onto topic maps using XSLT transformations and how thi...
