  1. 6. Cam Roller Contact

    Författare :Frederic Cabanettes; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification of surfaces; wear test; roller; rough contact model; surface topography; injection cam; manufacturing evaluation;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance andlegislation demands. First order aspects defining the main functions of a component are wellknown and new challenges appear at a lower scale. LÄS MER

  3. 7. Cam Roller Contact : The topographical aspect

    Författare :Frédéric Cabanettes; Bengt Göran Rosén; Peter Hansbo; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; injection cam; roller; surface topography; rough contact model; wear test; classification of surfaces; manufacturing evaluation; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. First order aspects defining the main functions of a component are well known and new challenges appear at a lower scale. LÄS MER

  4. 8. Soil identification by vibration measurements during soil-rock sounding

    Författare :Editha Ehrmanntraut; Stefan Larsson; Jörgen Johansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ground vibrations; dynamic penetration testing; frequency; seismic test; vibration velocity; in-situ tests; markvibrationer; dynamiska sonderingsmetoder; frekvens; seismiska försök; vibrationshastighet; in-situ-försök; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : Dynamic penetration tests are frequently used as geotechnical site investigation methods. In Sweden, the main reason to choose a dynamic penetration method is to investigatedepth to bedrock, strength and deformation properties of soil, compaction, or pilingdepth. LÄS MER

  5. 9. Supporting Decisions on Regression test Scoping in a Software Product Line Context - from Evidence to Practice

    Författare :Emelie Engström; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Large software organizations with a product line development approach face many challenges regarding testing. Test managers need to make tradeoffs along three dimensions of repeated testing (abstraction level, time and product space) and consider a range of goals and constraints. LÄS MER

  7. 10. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Sammanfattning : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. LÄS MER
