Application of base station with array of intelligent antennas in the energy distribution sector
… presented. Such a system receives as inputs the geographic coordinates of network elements and automatically feeds an intelligent Yagi-Uda antenna array with the appropriate parameters, in order to optimize the radiation pattern in the desired directions. The newly presented model uses a …

A Systematic Review of the Viola palmata Species Complex in the Gulf Coastal Plain and Southern Appalachians
… of alleles, and analyzed for population and/or geographic patterns. At each population, soil characteristics including soil texture, pH, percent organic matter, and environmental parameters including slope degree, slope aspect, and geographic coordinates were recorded for analysis. Statistical …

A ocorrência de lagartos marinhos (Mosasauridade: Lepidosauria) e sua associação faunística no cretáceo da bacia Pernambuco - Paraíba, Nordeste do Brasil
… paleontological, and locality information. The geographic coordinates of the outcrops have been obtained using GPS, providing a more precise locality data than the ones available so far in the literature.

Multiscale Study of the Interactions between Climate, Land Use, and Agricultural Productivity in Western Sahel: A Case Study of Chad
… African Republic, Niger, Nigeria, and Sudan. The geographic coordinates of that area are: North 14.403, West 10.815, East 24.219, and South 7.328. Agricultural productivity country summary data for Chad was obtained from the Food and Agriculture Organization (FAO) of the United Nations. Other data …

Computing Two-Dimensional Unambiguous Horizontal Wave Number Spectra From OH Airglow Images
… then mapped onto a 256 x 256 rectilinear grid of geographic coordinates using a 9 x 9 Hamming-weighted sinc interpolation function. In practice, the choice of the image field-of-view (FOV) to be processed depends upon the region of interest in the spectrum. Accurate spectral magnitudes can be …

The Relative Contribution of Hudson River Tributaries to River Herring Spawning Dynamics
… modeling and subsequent population estimation. Geographic coordinates (NAD 1983 UTM Zone 18N) were recorded at sites of egg collection, and kernel density based functions in GIS were used to visualize the spatial distribution and estimated counts of river herring throughout a given system. The …

Where are you talking about? Advances and Challenges of Geographic Analysis of Text with Application to Disease Monitoring
… (called Geotagging) and grounded to their geographic coordinates (called Toponym Resolution). However, our research goes further than any previous work by showing how to distinguish the literal place(s) of the event (Spain, Malaga) from other linguistic types/uses such as nationalities …

An Analytical Study of Air-Sea CO2 Gas Exchange in the Northwest Mississippi Bight Region
… surface water, the wind speed relative to fixed geographic coordinates (Eulerian reference frame) is customarily used. The final hypothesis was surface currents would have an appreciable affect on CO2 flux rates throughout the region. An investigation of CO2 flux rates computed from wind speeds …

Probabilistic models for mobile phone trajectory estimation
… Markov Models to match noisy or sparsely sampled geographic (lat, lon) coordinates to a sequence of road segments on a map. We evaluate VTrack on 800 drive hours of GPS and WiFi localization data collected from 25 taxicabs in Boston. We find that VTrack tolerates significant noise and outages in …

Aplikace pro inteligentní logování polohy z GPS pro zařízení s OS Android
Cílem této práce je vytvořit samostatnou službu, která by zjišťovala, ukládala a přeposílala informace o poloze uživatele s operačním systémem Android. Informace by měli být přeposílány on-line. Ukládání polohy by mělo probíhat přes KML soubor, který by měla aplikace generovat.
