Combining the theories of politics of scale from political geography, security theory from international relations, and energy security theory, and putting the scale conversion of energy contention, geographical relationship and geo-structure in geo-setting, and the three properties of safety in consideration, this paper rebuilds a geo-energy security evaluation model and uses the model to quan...

The Gene Expression Omnibus (GEO) repository at the National Center for Biotechnology Information (NCBI) archives and freely disseminates microarray and other forms of high-throughput data generated by the scientific community. The database has a minimum information about a microarray experiment (MIAME)-compliant infrastructure that captures fully annotated raw and processed data. Several data ...

In this paper we present a simulator for GEO or MEObased communication systems. This simulator implements variable delay and bit error rate simulation and can be used to analyze communication scenarios involving one or more GEO/MEO or LEO spacecrafts and ground stations. First the paper gives a short overview over the original LEO simulator design from which the GEO simulator was derived. Then ...

Region Bliskiego Wschodu w historii ludzkości odgrywał istotne znaczenie geopolityczne i geoekonomiczne. Wynikało to z jego położenia geograficznego, co powodowało, że stanowił swego rodzaju „pomost” handlu łączącym Europę Azją Afryką. Współcześnie jednym kluczowym aspektów są znajdujące się na tych obszarach znaczące złoża ropy naftowej, a także zbiegające interesy mocarstw regionalnych global...

the caucasus region is located between the black sea and the caspian sea in south of the russian federation, north west of iran and north east of turkey. geographical situation and strategic significance of the south caucasus, have turned it to one of the most important parts of the world. in an atmosphere of the us -russia geostrategic competition and possibility of waging a cold war between t...

This paper describes a set of experiments for monolingual English retrieval at GEO-CLEF 2005. We evaluate a technique for spatial retrieval based on named entity tagging, toponym resolution, and re-ranking by means of geographic filtering. To this end, we present a series of systematic experiments in the Vector Space paradigm. We investigate plain bag-of-word versus a kind of phrasal retrieval,...

A Geographic Information Retrieval (GIR) model is defined and the architecture of a GIR system, named Geo-Finder, is described. The GIR system is constituted by two main modules. The geo-indexing module applies bipolar criteria to automatically identify the geo-reference focus (footprint) of textual documents. The geo-retrieval module applies a context dependent matching function to evaluate qu...

Geo-registration is the task of assigning geospatial coordinates to the pixels of an image and placing them in a geographic coordinate system. However, the process of geo-registration can impair the quality of the image. This paper studies this topic by applying a comparison methodology to uncorrected and geo-registered airborne hyperspectral images obtained from the RIT SHARE 2012 data set. Th...
