  1. 1. Scientizing performance in endurance sports : The emergence of ‘rational training’ in cross-country skiing, 1930-1980

    Författare :Daniel Svensson; Sverker Sörlin; Nina Wormbs; Leif Yttergren; Helena Tolvhed; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; History; environmental history; history of science; history of technology; landscape studies; cross-country skiing; Nordic skiing; endurance physiology; sport history; sportification; scientization; sport physiology; sport science; Sweden; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

    Sammanfattning : Elite athletes of today use specialized, scientific training methods and the increasing role of science in sports is undeniable. Scientific methods and equipment has even found its way into the practice of everyday exercisers, a testament to the impact of sport science. LÄS MER

  3. 2. Objects in Time : Studies of Persistence in B-time

    Författare :Tobias Hansson Wahlberg; Teoretisk filosofi; []
    Nyckelord :HUMANIORA; HUMANITIES; B-time; three-dimensionalism.; stage theory; tenselessness; persistence; perdurance; mereology; four-dimensionalism; dispositions; endurance; B-theory of time; change; temporary intrinsics;

    Sammanfattning : This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. LÄS MER

  4. 3. Models and Methods for Analysis and Improvementof Physical Work Environments

    Författare :Linda Rose; Roland Örtengren; Mats Ericson; Bengt Nordgren; Per Odenrick; Division of Human Factors Engineering Department of Product abd Production Development Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ergonomics; economics; risk management; work-related personal injuries; construction industry; fatigue reactions; EMG; endurance; recovery; modelling.;

    Sammanfattning : The aim of this thesis concerning work-related personal injuries was to obtain knowledge bases for two purposes. The first was to develop a model, the Ergo-Index, for use when comparing work situations regarding ergonomics and time aspects and choosing the most favourable working method. LÄS MER

  5. 4. On the Performance of Long-Range Autonomous Underwater Vehicles : Enhancing the Endurance of AUVs

    Författare :Clemens Deutsch; Jakob Kuttenkeuler; Roger Berg; Martin Ludvigsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous underwater vehicles; Underwater gliders; Propulsion; Fuel cell; Energy management strategies; Autonom undervattensfarkost; Undervattensglidning; Propulsion; Bränslecell; Energy Management Strategies; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to gather environmental data, provide bathymetric images, and perform manipulation tasks. These robots are used not only for scientific, but also for industrial and military purposes. LÄS MER

  7. 5. Elite sprinters, ice hockey players, orienteers and marathon runners : isokinetic leg muscle performance in relation to muscle structure and training

    Författare :Christer Johansson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; endurance; enzyme histocytochemistry; fatigue; ice hockey; isokinetic; muscle contraction; OBLA; orienteering; running;

    Sammanfattning : In male athletes from different sports, isokinetic knee extensor, and in orienteers also plantar flexor peak torque (PT), contractional work (CW) and integrated surface electromyograms (iEMG) were analysed.Single contraction PT, CW and iEMG in sprinters and marathon runners were signi­ficantly correlated to the cross-sectional area (CSA) of m.
