  1. 6. Physically Based Rendering of Synthetic Objects in Real Environments

    Författare :Joel Kronander; Jonas Unger; Anders Ynnerman; Greg Ward; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents methods for photorealistic rendering of virtual objects so that they can be seamlessly composited into images of the real world. To generate predictable and consistent results, we study physically based methods, which simulate how light propagates in a mathematical model of the augmented scene. LÄS MER

  3. 7. Physically based fibre kinking model for crash of composites

    Författare :Sergio Costa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinking; Crushing; FEA; damage mechanics; friction;

    Sammanfattning : Passenger cars are a major emitter of global warming gases which has led to tighter regulations being imposed on car manufacturers. An efficient way to reduce emissions is to reduce the weight of the cars. LÄS MER

  4. 8. Super duplex stainless steels : Microstructure and propertiesof physically simulated base and weld metal

    Författare :Vahid Hosseini; Leif Karlsson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Super duplex stainless steel; weld metal; physical simulation; phase balance; precipitation; secondary phases; corrosion; nitrogen loss; arc heat treatment; production technology; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : High-temperature processing and application of super duplex stainless steel(SDSS) are associated with the risk of changes in the ferrite/austenite balance and precipitation of secondary phases. This study was therefore aimed at improving knowledge about effects of thermal cycles on the microstructure and properties of SDSS base and weld metal. LÄS MER

  5. 9. Being physically active as an adult with congenital heart disease

    Författare :Annika Bay; Bengt Johansson; Kristina Lämås; Malin Berghammer; Camilla Sandberg; Anna Strömberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult congenital heart disease; congenital heart disease; heart defect; physical activity; exercise self-efficacy; muscle function; quality of life; nursing; interviews; content analysis; prevention; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : Background: Due to advances in medical and surgical care adults with congenital heart disease (CHD) is a growing and aging population, that now outnumbers the children with CHD. In general, adults with CHD have reduced aerobic exercise capacity and nearly half of the patients do not reach current recommendations on physical activity. LÄS MER

  7. 10. Physically based model for plasticity and creep of Ti-6Al-4V

    Författare :Bijish Babu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : Albeit Ti-6Al-4V has numerous salient properties, its usage for certain applications is limited due to the challenges faced during manufacturing. Understanding the dominant deformation mechanisms and numerically modelling the process is the key to overcome this hurdle. This work investigates plastic deformation of the alloy at strain rates from 0. LÄS MER
