  2. 1. Efficient Execution Paradigms for Parallel Heterogeneous Architectures

    Author : Konstantinos Koukos; Stefanos Kaxiras; Margaret Martonosi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupled Execution; Performance; Energy; DVFS; Compiler Optimizations; Heterogeneous Coherence; Computer Science; Datavetenskap;

    Abstract : This thesis proposes novel, efficient execution-paradigms for parallel heterogeneous architectures. The end of Dennard scaling is threatening the effectiveness of DVFS in future nodes; therefore, new execution paradigms are required to exploit the non-linear relationship between performance and energy efficiency of memory-bound application-regions.

  4. 2. Study of Multi-Radio Transmission Diversity in Heterogeneous Access Networks

    Author : Georgios Koudouridis; Gunnar Karlsson; Cigdem Sengul; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the advent of multi-radio access (MRA), an integration of differentradio access technologies (RATs) into a heterogeneous radio access network(RAN) becomes feasible. Such integration allows a user to be at any instantof time served by one or multiple radio accesses (RAs) concurrently, where anRA constitutes an independent radio resource, such as a carrier or a channel,implemented by a single RAT.

  5. 3. Essays on Mechanism Design

    Author : Albin Erlanson; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Multi-item auctions; Strategy-proofness; Package assignment;

    Abstract : This thesis makes a contribution to mechanism design: a field of economic theory concerned with constructing and analyzing economic mechanisms. Examples include design of auctions, voting systems, school choice, kidney exchange and many more. The thesis consists of four separate papers. READ MORE

  6. 4. Imaging diffusional variance by MRI [public] : The role of tensor-valued diffusion encoding and tissue heterogeneity

    Author : Filip Szczepankiewicz; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Diffusion MRI provides a non-invasive probe of tissue microstructure. We recently proposed a novel method for diffusion-weighted imaging, so-called q-space trajectory encoding, that facilitates tensor-valued diffusion encoding. READ MORE

  7. 5. Hypersensitivity to electricity : symptoms, risk factors and therapeutic interventions

    Author : Lena Hillert; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Persons reporting nonspecific health complaints attributed to activated electrical equipment have been a growing concern in Sweden in the last decades. The aims of this thesis were to investigate possible risk factors (personal and work-related), symptoms, and complaints associated with reported hypersensitivity to electricity (HE) and to test hypotheses concerning possible biological mechanisms and effective treatments.
