1. 16. Functional modelling of the human timing mechanism

   Författare :Guy Madison; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Brain mechanisms; Brownian motion; drift; dynamical systems; fractal; human; Gaussian noise; Hurst exponent; time; time series analysis; timing; Psykologi; Psychology; Psykologi; fysiologi; Physiology;

   Sammanfattning : Behaviour occurs in time, and precise timing in the range of seconds and fractions of seconds is for most living organisms necessary for successful interaction with the environment. Our ability to time discrete actions and to predict events on the basis of prior events indicates the existence of an internal timing mechanism. LÄS MER

3. 17. Cryogenic soil processes in a changing climate

   Författare :Marina Becher; Jonatan Klaminder; Johan Olofsson; Jan Karlsson; Niclas Börlin; Philip Wookey; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-sorted circle; Carbon storage; Soil motion; Terrestrial photogrammetry; Cryoturbation; Carbon fluxes; naturgeografi; Physical Geography;

   Sammanfattning : A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in combination with other cryogenic disturbance processes may play a profound role in controlling the carbon balance of the arctic soil.

4. 18. On Robotic Work-Space Sensing and Control

   Författare :Magnus Linderoth; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; computer vision; color constancy; motion blur; filter initialization; visual tracking; on-line trajectory generation; ball-catching robot; force control; robotic assembly; force estimation; perception-action capabilities.;

   Sammanfattning : Industrial robots are fast and accurate when working with known objects at precise locations in well-structured manufacturing environments, as done in the classical automation setting. In one sense, limited use of sensors leaves robots blind and numb, unaware of what is happening in their surroundings. LÄS MER

5. 19. Towards Safer and Risk-aware Motion Planning and Control for Robotic Systems

   Författare :Fernando S. Barbosa; Jana Tumova; Stephen Smith; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

   Sammanfattning : Safety and risk-awareness are important properties for robotic systems, be it for protecting them from potentially dangerous internal states, or for avoiding collisions with obstacles and environmental hazards in disaster scenarios. Ensuring safety may be the role of more than one algorithmic layer in a system, each with varying assumptions and guarantees. LÄS MER

7. 20. Anterior cruciate ligament injuries : studies on the adverse events and long-term outcomes

   Författare :Osama Omar; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The overall aims of this thesis were to identify the main adverse events after anterior cruciate ligament (ACL) injuries, to study the clinical presentation and the consequences of the adverse event (post-operative septic arthritis), and to report the long-term outcomes of patients who underwent acute anterior cruciate ligament reconstruction (ACLR) and those who underwent delayed ACLR. Study I investigated the reasons behind compensation claims filed to the patient insurance company (Löf) by patients with ACL injuries from 2005 to 2014. LÄS MER
