Identifying the main byproducts of SF6 decomposition proves to be an effective strategy for determining nature and severity internal discharge faults in gas-insulated switchgears (GISs). In this research, it was suggested utilize coordination polymer Zr-MOF-808 as a sensor decomposition. This study examined adsorption its products (CF4, CS2, SO2, SO2F2, SOF2) on Zr-MOF-808, utilizing Gaussian16...

The paper describes environmental project ZmapujTo.cz which is intended to fight against illegal waste dumps in the Czech Republic with using geographic information systems (GISs). The smartphone/tablet GIS reporting application ZmapujTo has been developed. This free available mobile application enables to report illegal dumps and also overloaded containers of municipal waste. The project Zmapu...

With the rapid development in Geographic Information Systems (GISs) and their applications, more and more geo-graphical databases have been developed by different vendors. However, data integration and accessing is still a big problem for the development of GIS applications as no interoperability exists among different spatial databases. In this paper we propose a unified approach for spatial d...

If Geographic Information Systems (GISs) contain multiple representations of the same geographic objects at different levels of detail, it becomes necessary to compare the different representations and assess whether they contradict each other or not. Topological information is generally considered first-class geographic information and as such the preservation of topological relations among ob...

[1] We have analyzed the relationship between surface air temperature (SAT), ground surface temperature (GST), and snow cover (SNC) over the terrestrial Northern Hemisphere based on general circulation model (GCM) simulations using GISS modelE forced with the observed SST and radiative forcing changes from 1951–1998. While SAT is the dominant influence on GST during the warm-season, it explains...

This paper synthesizes lessons learnt from research that aimed to identify land in the dryland regions of eight sub-Saharan African study countries where bioenergy feedstocks production has a low risk of detrimental environmental and socio-economic effects. The methodology involved using geographical information systems (GISs) to interrogate a wide range of datasets, aerial photograph and field...

Although many GIS have been successfully implemented, it has become quite clear that two-dimensional maps with most complex contours and color schema cannot precisely present multidimensional and dynamic spatial phenomena. Most GISs in use today have not been designed to support multimedia data and therefore have very limited capability due to the large data volumes, very rich semantics and ver...

Global positioning systems (GPSs) and geographical information systems (GISs) have been widely used to collect and synthesize spatial data from a variety of sources. New advances in satellite imagery and remote sensing now permit scientists to access spatial data at several different resolutions. The Internet facilitates fast and easy data acquisition. In any one study, several different types ...
