  2. 1. Physiological demands of competitive elite cross-country skiing

    Author : Magnus Carlsson; Michail Tonkonogi; Christer Malm; Eva Andersson; Högskolan Dalarna; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Performance capability; maximal oxygen uptake; lactate threshold; lean mass; double poling; power output; maximal speed; sprint skiing; distance skiing.; Hälsa och välfärd; Health and Welfare;

    Abstract : Introduction Researchers have, for decades, contributed to an increased collective understanding of the physiological demands in cross-country skiing; however, almost all of these studies have used either non-elite subjects and/or performances that emulate cross-country skiing. To establish the physiological demands of cross-country skiing, it is important to relate the investigated physiological variables to the competitive performance of elite skiers. READ MORE

  4. 2. Dynamic speed adaptation based on information technology - a theoretical background

    Author : Andras Varhelyi; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; driver acceptance; appropriate speeds; speed behaviour; critical conditions; Social sciences; Samhällsvetenskaper;

    Abstract : Knowledge on the factors influencing driver speed-behaviour, the relationship between speed and traffic safety and means to influence speed behaviour is systematised. Expert judgements and the high proportion of injury accidents show that improved speed adaptation has the largest safety potential in the following situations: - Road surface-, visibility and weather affected situations (e.

  5. 3. Limitations of maximal oxygen uptake during whole-body exercise

    Author : Thibault Brink-Elfegoun; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Oxygen uptake increases linearly with increased running speed or rate of work and finally reaches a maximum beyond which no effort can drive it further. This phenomenon is referred to as the plateau in oxygen uptake . READ MORE

  6. 4. Go with the flow : visually mediated flight control in bumblebees

    Author : Nellie Linander; Funktionell zoologi; []
    Keywords : insect; vision; Bombus terrestris; flight control; optic flow; centring; flight speed; height; viewing angle; learning flight; Insect; vision; Bombus terrestris; flight control; optic flow; centring; flight speed; height; viewing angle; learning flight;

    Abstract : Despite their small brains and tiny eyes, flying insects are capable of detecting and avoiding collisions with moving obstacles, and with remarkable precision they navigate through environments of different complexity. For this thesis, I have investigated how bumblebees use the pattern of apparent image motion that is generated in their eyes as they move through the world (known as optic flow), in order to control flight.

  7. 5. Synthesis and Realization of High-Speed Recursive Digital Filters

    Author : Håkan Johansson; Lars Wanhammar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Recursive digital filters restrict the sample frequency at which an implementation of the filters can operate. This bound is determined by the ratio between the number of delay elements and the operation latency in the recursive loops of the filters. READ MORE
