  2. 1. Anti-paternalism and Public Health Policy

    Author : Kalle Grill; Sven Ove Hansson; Martin Peterson; David Archard; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Alcohol Interlocks; Altruism; Anti-paternalism; Epistemic paternalism; Group consent; Harm principle; Interference; Invalidation of reasons; Liberalism; Limiting liberty; Private sphere; Product safety regulation; Public health policy; Reason-actions; Self-regarding; Social responsibility; Uncertain information; Withholding of information.; Practical philosophy; Praktisk filosofi;

    Abstract : This thesis is an attempt to constructively interpret and critically evaluate the liberal doctrine that we may not limit a person’s liberty for her own good, and to discuss its implications and alternatives in some concrete areas of public health policy. The thesis starts theoretical and goes ever more practical. READ MORE

  4. 2. Wheel-rail Interaction Analysis

    Author : Tanel Telliskivi; KTH; []
    Keywords : Archard; rolling-sliding; Winkler; wear simulation;

    Abstract : A general approach to numerically simulating wear in rollingand sliding contacts is presented in this thesis. A simulationscheme is developed that calculates the wear at a detailedlevel. READ MORE

  5. 3. Out-of-Round Railway Wheels - Causes and Consequences An Investigation Including Field Tests, Out-of-Roundness Measurements and Numerical Simulations

    Author : Anders Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygonalization; wheel flat; full-scale measurements; wear modelling; impact load detector; railway wheel out-of-roundness; wheel removal criterion; dynamic train-track interaction; corrugation;

    Abstract : Causes and consequences of out-of-round railway wheels are investigated through literature studies, full-scale field experiments, out-of-roundness measurements, and numerical simulations. Both defects around the complete wheel circumference (e.g. polygonal wheels with wavelengths up to one wheel circumference) and local defects (e. READ MORE

  6. 4. Modelling of wear and galling in press hardening simulations

    Author : Liang Deng; Mats Oldenburg; Karl Nielsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Implementation of press hardened parts in automobile responses to the requirement of reduced carbon dioxide emission because the press hardened part has very high ratio of strength to weight. Furthermore, ultra high-strength steels (press hardened parts) increases the vehicle safety. READ MORE

  7. 5. Modelling of wear and tribofilm growth

    Author : Joel Andersson; Rob Bosman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Wear is a consequence of nature which becomes costly if uncontrolled. Basic wear protection is provided by lubrication which will decrease the severity of the contact between asperities. READ MORE
