  1. 1. Abdominal aortic aneurysm inception and evolution - A computational model

    Author : Andrii Grytsan; T. Christian Gasser; Martin Kroon; Frans N. van de Vosse; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aorta; Aneurysm; AAA; Blood Flow; Wall Shear Stress; Growth and Remodeling; Mixture Model; Growth Kinematics; Fluid-Solid-Growth; Aorta; Aneurysm; AAA; Blodflöde; Vägg Skjuvspänning; Tillväxt och Strukturförändring; Blandning Modell; Tillväxt Kinematik; Engineering Mechanics; Teknisk mekanik;

    Abstract : Abdominal aortic aneurysm (AAA) is characterized by a bulge in the abdominal aorta. AAA development is mostly asymptomatic, but such a bulge may suddenly rupture, which is associated with a high mortality rate. Unfortunately, there is no medication that can prevent AAA from expanding or rupturing. READ MORE

  2. 2. Double Poling Incross-Country Skiing : Biomechanical and Physiological Analysis of Sitting and Standing Positions

    Author : Marie Lund Ohlsson; Marko Laaksonen; Jonas Danvind; L. Joakim Holmberg; Anders Eriksson; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood lactate concentration; cross-country sit-skiing; impairment; internal kinetics; inverse dynamics simulations; joint reaction forces; kinematics; metabolic rate; musculoskeletal modelling; musculoskeletal efficiency; nordic skiing; oxygen uptake; para-skiing; respiration; skiing efficiency.;

    Abstract : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. READ MORE

  3. 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

  4. 4. Modelling of Delamination Growth in Composite Structures

    Author : Niklas E. Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large deformation; interface; composite materials; 3D-shell; cohesive zone; regularization; shell element; delamination;

    Abstract : Delaminations constitute an important damage and failure mode in polymeric composite laminates. In order to explicitly incorporate and model the delamination progression within a finite element analysis, the meso-modelling concept is applied in the present work. The laminate is thereby represented by separate layers connected with interfaces. READ MORE

  5. 5. Quantification of skeletal, muscular and kinematics parameters in scoliosis : methodological and clinical studies

    Author : Khaled Mohamed Diab; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Idiopathic scoliosis; new methods; scoliotic angle; vertebral body volume; intercostal muscle; ultrasonography; ground reaction force; centre of mass; centre of pressure; motor control;

    Abstract : This dissertation presents new methods derived for precise evaluation of a number of anatomical and functional variables of the complex thoracospinal deformity in scoliosis. By consensus the scoliotic angle at the frontal plane is measured on radiographs using the Cobb method. READ MORE
