  2. 21. Light propagation and photonic functionalization of semi-ordered material (transparent wood)

    Author : Adil Baitenov; Sergei Popov; Sergey Ponomarenko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; light scattering; scattering material; hierarchical structure; FEM model; wood modification; random lasers; dye lasers; transparent wood; adsorption; diffusive media; Optics and Photonics; Optik och fotonik;

    Abstract : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. READ MORE

  4. 22. Dynamic Performance and Design Aspects of Compliant Fluid Film Bearings

    Author : Matthew Cha; Sergei Glavatskih; Kyung-Woong Kim; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant bearing; dynamic performance; design aspects; Machine Design; Maskinkonstruktion;

    Abstract : Due to government regulations together with health and safety reasons, there are increasing demands on reducing hazardous polluting chemicals from fossil fuel power plants. Therefore, more efforts are imposed on using renewable resources such as water, wind, solar and tide to produce clean/green electricity. READ MORE

  5. 23. Nonlinear Isoviscous Behaviour of Compliant Journal Bearings

    Author : Matthew Cha; Sergei Glavatskih; Ilmar Santos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant Journal Bearings;

    Abstract : Plans to shut down nuclear power plants in some European countries as well as increased electricity production by wind and solar power will increase the work load on hydroelectric power plants in the future. Also, due to the power grid regulations, hydroelectric power plants undergo more frequent start-ups and shut-downs. READ MORE

  6. 24. Perturbation approach to reconstructions of boundary deformations in waveguide structures

    Author : Mariana Dalarsson; Martin Norgren; Sergei Tretyakov; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse problems; waveguides; microwaves; perturbation theory; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis we develop inverse scattering algorithms towards the ultimate goal of online diagnostic methods. The aim is to detect structural changes inside power transformers and other major power grid components, like generators, shunt reactors etc. READ MORE

  7. 25. Skeleton Programming for Heterogeneous GPU-based Systems

    Author : Usman Dastgeer; Christoph Kessler; Kristian Sandahl; Sergei Gorlatch; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Skeleton programming; GPU programming; SkePU; performance; portability; Computer science; Datavetenskap;

    Abstract : In this thesis, we address issues associated with programming modern heterogeneous systems while focusing on a special kind of heterogeneous systems that include multicore CPUs and one or more GPUs, called GPU-based systems.We consider the skeleton programming approach to achieve high level abstraction for efficient and portable programming of these GPU-based systemsand present our work on SkePU library which is a skeleton library for these systems.
