Navigation geo-database is the foundation and vital component of vehicle navigation system. Now almost geo-database is stored in hardware, such as CD, DVD. But, with the development of urban construction, road networks often change, as well as traffic rules. In order to reflect the changes of reality, direct the uses correctly and timely, it’s necessary to update geographic database on time. Th...

there have been different indices identified for desertification. among these is technogenic desertification index which seems much more efficient. in this study, some of technogenic desertification indices were studied and evaluated. first land use maps of the region were taken from irs-pan satellite image and aerial photos analysis. after evaluating the area of different uses, lands that had ...

this paper reports a survey and case study research outcomes on the application of data envelopment analysis (dea) to the ranking method of european foundation for quality management (efqm) business excellence model in iran’s automotive industry and improving benchmarking process after assessment. following the global trend, the iranian industry leaders have introduced the efqm practice to thei...

Ground target surveillance is getting a more and more important task, for civil as for military applications. Ground targets may be bound to infrastructural constraints, like vehicles moving on roads. Therefore, incorporating road map information into the tracking process is a current topic of research. This paper presents a tracking algorithm, which considers the road information and is based ...

We automate the organization of GPS data to create a visibility map with correctly connected intersections. For our example case study, we use GPS data collected on the Swarthmore College campus. After the data is automatically organized and cleaned, a user is able to select points on a visual map to search for an optimal path between those points. 1 The Problem of Navigation Swarthmore College...

The foundation of thrombolytic therapy for acute stroke rests on the NINDS IV tPA trial published in 1995 [1] and the PROACT II intra-arterial trial published in 1999 [2] . Based on NINDS and PROACT II, virtually all major stroke centers now routinely perform IV and IA thrombolysis in patients with acute ischemic stroke. The early road to thrombolytic stroke therapy had many twists and turns, s...

variety of maps for each country or territory. These will include information about different features, such as geology, climate, population and so on. Integrating information from the different maps allows the reader to appreciate the landscape they are exploring. The same is true for cellular maps that chart genetic, protein or functional interactions within the cell. Now, in Journal of Biolo...

Ultimate pressure of a well-designed vacuum system very much depends on pretreatments, processing and procedures [1, 2]. Until now much attention has been paid to minimizing hydrogen outgassing from the vacuum chamber wall materials, however, procedures and processing deserve further scrutiny. For reducing the gas load, high sensitivity helium leak detection techniques with sensitivities better...

Exosomes, first isolated 30 years ago, are nanoscale vesicles shed by most types of cells. The nucleic acid rich content of these nanoparticles, floating in virtually all bodily fluids, has great potential for non-invasive molecular diagnostics and may represent a novel therapeutic delivery system. However, current isolation techniques such as ultracentrifugation are not convenient and do not r...

The existence of a Broadcast-technology Management Committee (BMC) in the EBU is not to suggest that developments in broadcast technology can be managed by the EBU alone. Although in the past many technical developments were initiated by EBU Members and developed collectively in EBU working groups, the developments in broadcast technology nowadays take place in organizations which extend well o...
