  1. 1. Tilting trains : Technology, benefits and motion sickness

    Författare :Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

    Sammanfattning : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. LÄS MER

  3. 2. Tilting trains : Enhanced benefits and strategies for less motion sickness

    Författare :Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; running time; ride comfort; motion sickness; tilt control; Vehicle engineering; Farkostteknik; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget;

    Sammanfattning : Carbody tilting is today a mature and inexpensive technology that allows higher train speeds in horizontal curves, thus shortening travel time. This doctoral thesis considers several subjects important for improving the competitiveness of tilting trains compared to non-tilting ones. LÄS MER

  4. 3. Ride comfort and motion sickness in tilting trains

    Författare :Johan Förstberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tilting train; Ride comfort; Motion sickness; Simulator; Experiments;

    Sammanfattning : This thesis presents a systematic study of human responses to different motions and strategies of car body tilt control regarding ride comfort, working/reading ability and motion sickness on high-speed tilting trains. Experiments with test subjects were performed in a tilting train on curved track as well as in a moving vehicle simulator. LÄS MER

  5. 4. Stratified algebras and classification of tilting modules

    Författare :Elin Persson Westin; Volodymyr Mazorchuk; Aslak Buan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Representation theory; Generalized tilting module; Exceptional sequence; Quasi-hereditary algebra; Standardly stratified algebra; Essential order; Category O; S-subcategory; Projective dimension; Finitistic dimension; Mathematics; Matematik;

    Sammanfattning : This thesis contains three papers in representation theory of algebras. It mainly studies two types of algebras; quasi-hereditary algebras and standardly stratified algebras. LÄS MER

  7. 5. Submerged Transmission in Wave Energy Converters : Full Scale In-Situ Experimental Measurements

    Författare :Erland Strömstedt; Mats Leijon; Hans Bernhoff; Jan-Olov Aidanpää; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; direct drive; submerged transmission; piston rod; seal housing; sealing system; laser triangulation sensor; offshore measurements; relative displacement; vibrations; tilt angle; tilting; wear estimation.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. LÄS MER
