2. 1. Assessment of predicting blood flow and atherosclerosis in the aorta and renal arteries

   Author : Alexander Fuchs; Lisa Prahl Wittberg; Örjan Smedby; Chunliang Wang; Anders Persson; Elazer Edelman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blodflödessimulering; Åderförkalkning; Väggskjuvspänning; Blodrehologiska modeller; Engineering Mechanics; Teknisk mekanik;

   Abstract : Cardiovascular diseases (CVD) are the most common cause of death in large parts of the world. Atherosclerosis (AS) has a major part in most CVDs. AS is a slowly developingdisease which is dependent on multiple factors such as genetics and life style (food, smoking, and physical activities). READ MORE

4. 2. Combined Digital Holography and Speckle Correlation for Rapid Shape Evaluation

   Author : Davood Khodadad; Anna Runnemalm; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik; Maskinteknik;

   Abstract : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing thecontrolled parts. READ MORE

5. 3. Long freight trains and long-term rail surface damage

   Author : Visakh V Krishna; Sebastian Stichel; Mats Berg; Carlos Casanueva; João Pombo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track friendliness; rail surface damage; multi-body simulation; longitudinal train dynamics; track maintenance; rolling contact fatigue; wear; Engineering Mechanics; Teknisk mekanik; Vehicle and Maritime Engineering; Farkostteknik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

   Abstract : Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. READ MORE

6. 4. Constrained Optimization for Prediction of Posture

   Author : Erik J. Dijkstra; Elena M. Gutierrez-Farewik; Anders Eriksson; Mikael Skipper Andersen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Static optimization; Multibody system; Musculoskeletal model; Engineering Mechanics; Teknisk mekanik;

   Abstract : The ability to stand still in one place is important in a variety of activities of daily living. For persons with motion disorders, orthopaedic treatment, which changes geometric or biomechanical properties, can improve the individual'sposture and walking ability. READ MORE

7. 5. Inflation and Instabilities of Hyperelastic Membranes

   Author : Amit Patil; Anders Eriksson; Arne Nordmark; Peter Hansbo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Constrained inflation; Energy release rate; Adhesive contact condition; Limit point; Bifurcation point; Wrinkling; Tension field theory; Pressure induced instability.; Teknisk mekanik; Engineering Mechanics;

   Abstract : The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours.
