In the study "Building a 3D information model for underground coal mines" a 3D information model for a mine is built using BIM. The Industry Foundation Classes (IFC) standard is used to define the mining information model. Point clouds collected by Terrestrial laser scanning (TLS) provide geometric and attributive information for building BIM models. This information model was applied to the NUI BEO underground coal mine. The information model was built for important structures of the mine, including the mine shaft and tunnels.

The research "Detection of land surface temperature change in coal mining area using remote sensing and GIS techniques - A case study in Quang Ninh province, Vietnam" explores Land Surface Temperature (LST), which represents the energy exchange between the land surface and the atmosphere, as well as with the biosphere. Variations in surface temperature can lead to the formation of heat islands characterized by higher temperatures compared to surrounding areas.

The autoplaque or autolysis of bacterial cell influences the evolutionary potential of clinically important bacteria. It serves as a selection pressure on a bacterial community and provides social goods (nutrients, secondary metabolites, free DNA) in environment. Therefore, it has a major impact on the ecological fitness of microbial communities; however its prevalence in microbial communities of degraded ecosystems is not known.

We aim to automatically extract species names of bacteria and their locations from webpages. This task is important for exploiting the vast amount of biological knowledge which is expressed in diverse natural language texts and putting this knowledge in databases for easy access by biologists.

I promised I would come, Now I have been awaken; Soon to creep through this land, Taking what I am owed. You have something of mine, I have come to collect; You can gently submit, Or have it ripped from you. I am now your father, Bow before me faithful child; Do not hesitate, For you chose your own path.

Spatial or territorial organization is one of effective tools for sustainable land use. Spatial organization of land use and environmental protection by functional sub-areas is performed on the basis of comprehensive and integrated research on characteristics and differentiation laws of natural components and landscapes, socio-economic factors, the present status and trend of environmental changes as well as the structures and functions of sub-areas. Uong Bi is a national center for tourism, coal mining and thermal power production.

The biological sciences have become more quantitative and information-driven since emerging computational and mathematical tools facilitate collection and analysis of vast amounts of biological data. Complexity analysis of biological systems provides biological knowledge for the organization, management, and mining of biological data by using advanced computational tools. The biological data are inherently complex, nonuniform, and collected at multiple temporal and spatial scales.
