  1. 1. TOWARDS VALIDATED CATALYTIC REACTOR MODELS

    Författare :Magnus Walander; Chalmers University of Technology; []
    Nyckelord :EATS; scanning electron microscope; Exhaust aftertreatment modelling; gravimetric analysis; effective diffusivity; synthetic catalyst activity test; washcoat; diesel oxidation catalyst;

    Sammanfattning : The use of liquid fuels in the internal combustion engine inherently produces several toxic emissions that need to be removed. This is done through a series of catalytic converters, referred to as the exhaust aftertreatment system (EATS), each catalyst with its own purpose. LÄS MER

  2. 2. Modelling of Catalytic Monolith Reactors for Exhaust Aftertreatment

    Författare :Magnus Walander; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parameter estimation; effective diffusivity; EATS; synthetic catalyst activity test; scanning electron microscope; washcoat; diesel oxidation catalyst; Exhaust aftertreatment modelling; gravimetric analysis;

    Sammanfattning : The incomplete combustion of liquid or gaseous fuels in the internal combustion engine inherently produces several toxic emissions that need to be  removed. This is done through a series of catalytic converters, referred to as the exhaust aftertreatment system (EATS), each catalyst with its own purpose. LÄS MER

  3. 3. Three-dimensional analysis of aeromagnetic and gravimetric data of sedimentary basins from Panama, Central America

    Författare :Luis E. Santamaria Vallejos; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Sammanfattning : The knowledge of the geology of the sedimentary basins from the Gulf of Panama is still quite limited. There is a lack of data from the basin geometry, the thickness, the continuity and connection between the basins, and from the characteristics of the crystalline basement rocks beneath the sedimentary basins.

  4. 4. Contributions of Satellite Geodesy to Post-Glacial Rebound Research

    Författare :Seyed Mehdi Shafiei Joud; Lars E. Sjöberg; Mohammad Bagherbandi; Martin Horwath; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Glacial Isostatic Adjustment GIA ; gravimetric GIA modelling; satellite geodesy; Gravity Recovery And Climate Experiment GRACE ; independent component analysis ICA ; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Glacial Isostatic Adjustment (GIA) is a global and long-term process in the Earth, which began 21.5 millennia ago, according to many ice history modellers. One way to understand the processes of the Earth’s interior, the crustal deformation, and a key correction to estimate the climatological parameters is obtained by studying GIA. LÄS MER

  5. 5. Height determination by GPS : A practical experiment in central Sweden

    Författare :Stig-Göran Mårtensson; Högskolan i Gävle; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Division of Geodesy Reports; Surveying; Lantmäteri;

    Sammanfattning : GPS as a height measuring tool has been widely introduced for solving various tasks within the fields of Geodesy and Engineering Surveying. The obvious advantage of not needing lines of sight when acquiring height differences is, however, darkened by the fact that GPS and traditional spirit levelling have fundamentally different reference systems for heights.
