  1. 16. Optimizing Massive MIMO : Precoder Design and Power Allocation

    Författare :Hei Victor Cheng; Erik G. Larsson; Marius Pesavento; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The past decades have seen a rapid growth of mobile data traffic,both in terms of connected devices and data rate. To satisfy the evergrowing data traffic demand in wireless communication systems, thecurrent cellular systems have to be redesigned to increase both spectralefficiency and energy efficiency. LÄS MER

  3. 17. Anomaly and Topology : On the axial anomaly, domain wall dynamics, and local topological markers in quantum matter

    Författare :Julia D. Hannukainen; Jens H. Bardarson; Adolfo G. Grushin; Teemu Ojanen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chiral anomaly; axial anomaly; topological phases of matter; Weyl semimetals; magnetic domain walls; local topological markers;

    Sammanfattning : Chiral anomalies and topological phases of matter form the basis of the research presented in this dissertation. The chiral anomaly is considered both in the context of magnetic Weyl semimetals and in the context of non-Hermitian Dirac actions. LÄS MER

  5. 19. Skew-symmetric matrix pencils : stratification theory and tools

    Författare :Andrii Dmytryshyn; Bo Kågström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Investigating the properties, explaining, and predicting the behaviour of a physical system described by a system (matrix) pencil often require the understanding of how canonical structure information of the system pencil may change, e.g., how eigenvalues coalesce or split apart, due to perturbations in the matrix pencil elements.

  7. 20. Structure and Interactions of the Extracellular Matrix Protein PRELP

    Författare :Eva Bengtsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reumatologi; muskelsystem; Skelett; extracellular matrix; PRELP; heparin; heparan sulfate; perlecan; collagen; cell-binding; Skeleton; rheumatology locomotion; muscle system; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : This thesis describes the structure and interactions of a novel extracellular matrix protein - PRELP (proline arginine-rich end leucine-rich repeat protein). The amino acid sequence of PRELP showed that it belonged to the leucine-rich repeat (LRR) protein family in connective tissues. LÄS MER
