  1. 1. Analysis and Design of Rateless Codes

    Författare :Iqbal Hussain; Lars Kildehøj Rasmussen; Petar Popovski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The invention of turbo codes and the re-discovery of sparse graph codes constitute a milestone in error-correction codes designed for communication and storage systems. Sparse graph codes such as low-density parity-check codes can offer a performance that approaches the previously elusive Shannon capacity with reasonable practical computational complexity. LÄS MER

  3. 2. Catabolism of Pyrimidines in Yeast

    Författare :Anna Rasmussen; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pyrimidine degradation; catabolism of pyrimidines; nucleic acid precursors; yeast; Lachancea kluyveri; URC pathway;

    Sammanfattning : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. LÄS MER

  4. 3. Feedback control of cerebellar learning

    Författare :Anders Rasmussen; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; Rescorla-Wagner; Anticipation; In vivo Electrophysiology; Purkinje cells; Nucleo-Olivary inhibition; Inferior Olive; Classical Conditioning; Eyeblink Conditioning; Feedback;

    Sammanfattning : The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. LÄS MER

  5. 4. Att kunna lyssna med kroppen : En studie av gestaltande förmåga inom gymnasieskolans estetiska program, inriktning teater

    Författare :Pernilla Ahlstrand; Ingrid Carlgren; Eva Österlind; Bjørn Rasmussen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; theatre education; knowledge; knowing; didactics; tacit knowledge; learning study; upper secondary school; teacher professionalization; utbildningsvetenskap med inriktning mot praktiska kunskapstraditioner; Educational Sciences in Arts and Professions;

    Sammanfattning : Theatre has been a school subject in the Swedish upper secondary school's national arts program since 1992 and has its own syllabus and grading criteria. The National Curriculum in theatre emphasises the development of performative capability, which is the focus of this dissertation. LÄS MER

  7. 5. A Statistical-Physics Approach to the Analysisof Wireless Communication Systems

    Författare :Maksym Girnyk; Lars K. Rasmussen; Giuseppe Caire; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless communications; statistical physics; random matrix theory; large-system analysis; MIMO; 5G; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Multiple antennas at each side of the communication channel seem to be vital for future wireless communication systems. Multi-antenna communication provides throughput gains roughly proportional to the smallest number of antennas at the communicating terminals. LÄS MER
