  1. 1. A study of vehicle fatigue damage predictions based on state estimations

    Författare :Ulrika Lagerblad; Artem Kulachenko; Henrik Wentzel; Costas Papadimitriou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; State estimations; Fatigue damage; Damage predictions; Fixed-lag Kalman Smoother; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Individual health monitoring of heavy vehicles is one of the keystones on which an optimized utility of a vehicle fleet is based. For many components mounted on the chassis of a heavy vehicle, failures due to fatigue is a major concern. LÄS MER

  3. 2. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

    Författare :Anton Albinsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; state estimation; vehicle dynamics; parameter estimation; tyre-road friction estimation; active safety;

    Sammanfattning : Electric vehicles have the potential to significantly reduce energy consumption and emissions for personal and commercial road transport and number of electric vehicles is likely to increase in the future due to stricter emission legislations. In order to accelerate market penetration, the competiveness of electric vehicles should increase in comparison to conventional vehicles. LÄS MER

  4. 3. Shear cracks in concrete structures subjected to in-plane stresses

    Författare :Richard Malm; Håkan Sundquist; Kent Gylltoft; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shear; plane state stress; crack width; FE analysis; design standards; serviceability state; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : After only two years of service, extensive cracking was found in the webs of two light-rail commuter line bridges in Stockholm, the Gröndal and Alvik bridges. Due to this incident it was found necessary to study the means available for analysing shear cracking in concrete structures subjected to in-plane stresses. LÄS MER

  5. 4. Anchoring biases in estimations of age, weight and height

    Författare :Linda Langeborg; Mårten Eriksson; Peter Juslin; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; anchoring; anchor effects; own-anchor effect; assimilation; contrast; age estimation; weight estimation; height estimation; social judgments;

    Sammanfattning : The main purpose of this thesis was to study the circumstances under which anchoring biases occur for estimation of age, weight and height. Paper I investigated accuracy and biases in age estimates made by salespersons with experience in age estimation, compared to a control group without any similar experience. LÄS MER

  7. 5. Data-Driven Approaches for Traffic State and Emission Estimation

    Författare :Nikolaos Tsanakas; Jan Lundgren; Joakim Ekström; Johan Olstam; David Gundlegård; J.W.C. van Lint; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Traffic congestion is one of the most severe problems in modern urban areas. Besides the amplified travel times, traffic congestion intensifies the amount of emitted pollutants impacting human health and the environment. LÄS MER
