3. 12. Optimization methods for vehicle body structures

   Författare :Harald Fredricson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis is concerned with the use of optimization methods in the vehicle industry. Numerical optimization has been used with limited extend in the vehicle industry. However, great potential of using optimization methods has been identified during the development process of vehicle body structures. LÄS MER

4. 13. När kunskap ska styra : Om organisatoriska och professionella villkor för kunskapsstyrning inom missbruksvården

   Författare :Maria Alm; Håkan Jenner; Joakim Krantz; Per-Olof Thång; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; knowledge governance; knowledge management; evidence-based practice; substance abuse treatment; knowledge to practice; ASI; DOC; neo-institutional theory; professional theory; Education; Pedagogik;

   Sammanfattning : This thesis focuses on the changed governance of the public sector and what it can entail for professional work in substance abuse treatment. The point of departure is one of these new forms of governing, namely ‘knowledge governance’, which refers to a policy-driven process for promoting the use of evidence-based practice. LÄS MER

5. 14. The importance of body-mass exponent optimization for evaluation of performance capability in cross-country skiing

   Författare :Tomas Carlsson; Michail Tonkonogi; Christer Malm; Klavs Madsen; Högskolan Dalarna; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allometric scaling; power-function modelling; maximal oxygen uptake; body mass; elite skiers; distance skiing; lactate threshold; double poling; sprint skiing; competition; power output; time trial; Hälsa och välfärd; Health and Welfare;

   Sammanfattning : Introduction Performance in cross-country skiing is influenced by the skier’s ability to continuously produce propelling forces and force magnitude in relation to the net external forces. A surrogate indicator of the “power supply” in cross-country skiing would be a physiological variable that reflects an important performance-related capability, whereas the body mass itself is an indicator of the “power demand” experienced by the skier.

7. 15. Correlation between Track Irregularities and Vehicle Dynamic Response Based on Measurements and Simulations

   Författare :Tomas Karis; Mats Berg; Jens Nielsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track irregularities; vehicle response; wheel–rail force; axle box acceleration; Dynotrain; Gröna Tåget; multi-body system; simulations; spårlägesfel; fordonsrespons; hjul–räl-krafter; axelboxacceleration; Dynotrain; Gröna Tåget; flerkroppssystem system; simuleringar; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Vehicle and Maritime Engineering; Farkostteknik; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Deviations from the design track geometry are called track irregularities, which are a main excitation mechanism in the track–vehicle dynamic system, and very important to monitor and maintain to have trac on a line run safely and comfortably. Especially during vehicle acceptance testing, it is important that a new vehicle behaves close to design predictions and within limit values, thus it is important to be able to describe track irregularities in a consistent way.
