  1. 11. Value of Information Analysis in Rock Engineering Investigations

    Författare :Miriam Zetterlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Observational Method; Rock mass characterisation; Value of Information;

    Sammanfattning : A challenge in rock engineering is to strike a balance between a reasonable level of investigation and uncertainty in the geological conditions. Value of Information Analysis (VOIA) provides support for decisions about investigation strategies. LÄS MER

  3. 12. Studies of Volcanic Plumes with Spectroscopic Remote Sensing Techniques

    Författare :Santiago Arellano; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Remote Sensing; FTIR; DOAS; Volcanic gas emissions;

    Sammanfattning : Volcanism is a widespread phenomenon on Earth and other planetary bodies. Terrestrial volcanoes are shallow manifestations of deep and complex mechanisms of heat and mass transport and play an important role in the formation and change of the atmosphere and the natural landscape.

  4. 13. Integration of BIM and 3D GIS for sustainable cadastre

    Författare :Jing Sun; Kent Eriksson; Lars Harrie; Jenny Paulsson; Milan Horemuz; Peter van Oosterom; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; BIM; 3D GIS; 3D cadastre; LADM; business ecosystem; cadastre ecosystem; sustainability; Geodesi; Geodesy;

    Sammanfattning : Building Information Modelling (BIM) has prominently innovated and digitalized buildingenvironment through digital representation of buildings, lifecycle process and managementfor involved actors. Rapidly developed from Geographical Information System (GIS) domain,three-dimensionally (3D) GIS provides powerful and comprehensive functions of planning,modelling, visualizing and analyzing 3D geodata in large scale.

  5. 14. Detection and classification of sea ice from spaceborne multi-frequency synthetic aperture radar imagery and radar altimetry

    Författare :Wiebke Aldenhoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beaufort Sea; sea ice classification; sea ice; sea ice concentration; Fram Strait; SAR imaging; radar altimetry;

    Sammanfattning : The sea ice cover in the Arctic is undergoing drastic changes. Since the start of satellite observations by microwave remote sensing in the late 1970's, the maximum summer sea ice extent has been decreasing and thereby causing a generally thinner and younger sea ice cover.

  7. 15. Sea Ice Concentration Estimation and Ice Type Classification from Dual-Frequency Satellite Synthetic Aperture Radar

    Författare :Wiebke Aldenhoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sea ice concentration; sea ice; SAR imaging; sea ice classification; Fram Strait;

    Sammanfattning : The sea ice cover in the Arctic has undergone dramatic changes in recent years. The perennial sea ice extent is decreasing by 12.2 % per decade while annual mean sea ice thickness has decreased by more than 2 m for the central Arctic Basin from 1975 to 2012. LÄS MER
