  2. 1. Growing into Voting : Election Turnout among Young People and Habit Formation

    Author : Richard Öhrvall; Elin Wihlborg; Gissur Ó Erlingsson; Sven Oskarsson; Jan Teorell; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Voter turnout; political equality; habit formation; youth participation; Valdeltagande; politisk jämlikhet; vaneröstande; ungas deltagande;

    Abstract : This thesis contains an introduction and four essays that together address the issues of turnout and habitual voting. Although voting is less unequal than other forms of political participation, it is still biased in favour of more socially affluent citizens.  One way to achieve more equal participation is to increase the general turnout.

  4. 2. Towards Optimization of Railway Turnouts

    Author : Björn Pålsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic vehicle–track interaction; turnout; switch crossing; wheel and rail wear;

    Abstract : The turnout (Switch & Crossing) is a vital component in railway networks as it provides flexibility to traffic operation by allowing trains to switch between tracks. The flexibility comes at a cost as the common lack of a transition curve in the diverging route together with the variation and discontinuities in rail profiles result in higher rail degradation rates than in regular track.

  5. 3. Mating and Political Inequality

    Author : Moa Frödin Gruneau; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political inequality; Mating; Turnout; Political represenation;

    Abstract : Political equality is one of the cornerstones of a well-functioning democracy. Yet, very few democracies live up to this ideal. In this dissertation, I show that a central part of human behavior, mating, can help us explain why political inequalities are difficult to change. READ MORE

  6. 4. Wheel–Rail Impact Loads and Track Settlement in Railway Crossings

    Author : Xin Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle--track dynamics; wheel--rail contact; track settlement; material modelling of ballast; Switches and crossings; turnout; cyclic loading; Green s functions;

    Abstract : Turnouts (Switches & Crossings, S&C) are critical components of a railway track requiring regular maintenance and generating high life cycle costs. A main driver for the high maintenance costs is the need to repair and replace switch rails and crossings as these components are subjected to a severe load environment. READ MORE

  7. 5. Optimisation of Railway Switches and Crossings

    Author : Björn Pålsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel and rail wear; railway turnout; optimisation; switch crossing; dynamic vehicle-turnout interaction;

    Abstract : Methods for simulation-based optimisation of the design of railway turnouts (switches & crossings, S&C) are developed and demonstrated. Building on knowledge of dynamic wheel–rail interaction in turnouts, it is investigated how rail profile degradation can be reduced by the optimisation of geometry and component stiffness of the track superstructure.
