  2. 1. The drive for change putting the means and ends of sport at stake in the organizing of Swedish voluntary sport

    University dissertation from Umeå : Umeå University

    Author : Cecilia Stenling; Umeå universitet.; [2015]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; organizational institutionalism; institutional logics; community sport clubs; voluntary organizations; civil society; governance; organizational change; public policy; sport policy; policy implementation; popular movements; institutionell teori; institutionella logiker; föreningsidrott; idrottsföreningar; idrottsrörelsen; folkrörelse; organisatorisk förändring; idrottspolitik; policy-implementering; civilsamhället; tredje sektorn; pedagogik; Education;

    Abstract : The aim of this thesis is to create knowledge on processes of change in the contemporary organizing of Swedish voluntary sport and the systems of meaning at work in these processes. The thesis proceeds from the assumption that the contemporary public sport policy climate is characterized by a pressure on organized sport to change in order for sport to better serve as an implementer of non-sport goals.

  4. 2. On Drive Force Distribution and Road Vehicle Handling - A Study of Understeer and Lateral Grip

    University dissertation from Umeå : Umeå University

    Author : Matthijs Klomp; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drive force distribution; drive force; vehicle handling; lateral grip; understeer; acceleration; steady-state cornering; vehicle dynamics; combined slip;

    Abstract : Computer controlled vehicle sub-systems aimed to support drivers in various drivingsituations are rapidly increasing in number and sophistication. These systemshave evolved from anti-lock braking and traction control systems, to electronic stabilitycontrol. READ MORE

  5. 3. Fast wave heating and current drive in tokamaks

    University dissertation from Stockholm : KTH

    Author : Martin Laxåback; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tokamak; JET; ITER; thermonuclear fusion; fast wave; heating; current drive; ion cyclotron resonance; polychromatic; finite orbit widths; RF-induced transport; neutral beam injection; fusion born alpha particles; magnetosonic eigenmodes; parasitic absorption; modelling; weighted Monte Carlo scheme; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : This thesis concerns heating and current drive in tokamak plasmas using the fast magnetosonic wave in the ion cyclotron range of frequencies. Fast wave heating is a versatile heating method for thermonuclear fusion plasmas and can provide both ion and electron heating and non-inductive current drive. READ MORE

  6. 4. Efficiency Analysis of Drive-train for an Electrified Vehicle

    University dissertation from Stockholm : KTH

    Author : Ali Rabiei; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drive cycles; Current vector control; Vehicle applications; Silicon carbide; Power electronics; Energy efficiency; Loss calculation; Electric machines;

    Abstract : In this PhD thesis, various solutions to improve the energy efficiency in the electrical drive-train of an electrified vehicle such as modifications of the propulsioninverter or control of the electric machine, are proposed and their benefits arequantified from an energy efficiency point of view. The efficiency analysis isbased on modeling of a power electronics inverter, an electric machine and a battery in various drive cycles for an electrified vehicle. READ MORE

  7. 5. On the Load Distribution and Design of a Chain Drive

    University dissertation from Machine Elements Division, P.O.Box 118,SE- 22100 Lund,Sweden

    Author : Ingvar Troedsson; Lunds universitet.; Lund University.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE
