2. 1. Numerical analysis of coalescence-induced jumping droplets on superhydrophobic surfaces

   Author : Konstantinos Konstantinidis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; jumping droplets; immersed boundary; CFD; surfaces; superhydrophobic; contact angle; VOF; coalescence; self-cleaning; wetting; hysteresis;

   Abstract : Bio-inspired superhydrophobic surfaces are used in numerous technological applications due to their self-cleaning ability. One of the several mechanisms reported in literature and responsible for self-cleaning is the phenomenon of coalescence-induced jumping of droplets from such surfaces. READ MORE

4. 2. Sport surfaces in show jumping

   Author : Elin Hernlund; Sveriges lantbruksuniversitet; null; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Properties of sport surfaces influence the occurrence of injuries and the performance of equine athletes. The sports governing body seeks to develop standards for safety and performance of show jumping surfaces. Limited information is available to guide this process. READ MORE

5. 3. Multiscale Modelling of Proximal Femur Growth : Importance of Geometry and Influence of Load

   Author : Priti Yadav; Elena Gutierrez Farewik; Marco Viceconti; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone tissue modeling; deformity; biomechanics; osteogenic index; poroelastic material; octahedral shear stress; hydrostatic stress; fluid velocity; octahedral shear strain; MRI; walking; jumping; sedentation; Engineering Mechanics; Teknisk mekanik;

   Abstract : Longitudinal growth of long bone occurs at growth plates by a process called endochondral ossification. Endochondral ossification is affected by both biological and mechanical factors. READ MORE

6. 4. Dangers in sport parachuting

   Author : Anton Westman; Ulf Björnstig; Inggard Lereim; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sport parachuting; skydiving; BASE jumping; injury; risk factors; epidemiology.; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : Background Sport parachuting is a dangerous recreational activity for which available literature appears unsatisfactory to form a basis for injury prevention. Aim Overall: Explore some risk factors in sport parachuting. Study I: Identify fatal incident and injury mechanisms for skydiving (sport parachuting from aircraft). READ MORE

7. 5. Identification and Control of Systems Subject to Abrupt Changes

   Author : Mille Millnert; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recursive identification; adaptive control; jumping parameters; Markov regime; time varying parameters;

   Abstract : Many different recursive identification methods for time varying systems have been suggested in the literature. An assumption that the variations in the system parameters are slow is common for almost all the methods. READ MORE
