  1. 6. Problems in the Classification Theory of Non-Associative Simple Algebras

    Författare :Erik Darpö; Ernst Dieterich; Karl-Heinz Fieseler; William Crawley-Boevey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Division algebra; flexible algebra; normal form; composition algebra; absolute valued algebra; vector product; rotation.; MATHEMATICS; MATEMATIK;

    Sammanfattning : In spite of its 150 years history, the problem of classifying all finite-dimensional division algebras over a field k is still unsolved whenever k is not algebraically closed. The present thesis concerns some different aspects of this problem, and the related problems of classifying all composition and absolute valued algebras. LÄS MER

  3. 7. Att få syn på avgörande skillnader : Lärares kunskap om lärandeobjektet

    Författare :Pernilla Mårtensson; Ulla Runesson; Ference Marton; Astrid Pettersson; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; teachers of mathematics; mathematics learning; pedagogical content knowledge; mathematical knowledge for teaching; learning study; variation theory; division; decimal numbers; equation of the straight line;

    Sammanfattning : Lärare som undervisar i matematik förväntas kunna mer avancerad matematik än vad de undervisar om. Men formell matematikkunskap anses inte vara tillräckligt för att lärare ska kunna undervisa så att ämnesinnehållet blir begripligt för eleverna, de behöver även pedagogical content knowledge (PCK).

  4. 8. Channel Related Optimization of Wireless Communication Systems

    Författare :Fredrik Tufvesson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time division duplex; multicarrier; Radio communication; orthogonal frequency division multiplex; channel estimation; pilot symbol assisted modulation; sub-channel spacing; sub-channel bandwidth; interchannel interference; cyclic prefix; intersymbol interference; Rayleigh fading; precoding; pre-compensation;

    Sammanfattning : This thesis deals with different optimization problems in the design of wireless communication systems. It is mainly directed to the design of systems based on multicarrier techniques and orthogonal frequency division multiplex, OFDM, but some of the problems apply to single carrier systems as well.

  5. 9. Another Modernism? Form, Content and Meanings of the New Housing Architecture of Hanoi

    Författare :Hoai Anh Tran; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vietnam; tradition; The West; Third World; identity; modernity; modernisation; modernism; modern architecture; house design; housing architecture; Architecture; Hanoi; interior design; Arkitektur; inredningsarkitektur;

    Sammanfattning : The study deals with the issue of how to understand and assess modern architecture in a non-Western context. Is there a non-Western modern architecture in its own right and with meanings connected to the local context or is it mere copy of Western modern architecture? At the primary level the study discusses the meanings and directions of contemporary architecture in a modernising society such as Vietnam, using a number of new private houses of Hanoi as case studies.

  7. 10. The role of gamma-tubulin in cell division and cancer

    Författare :Greta Eklund; Malmö Molekylär patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although cancer is a heterogeneous disease, a common theme in tumor cells is the deregulation of cell division, which renders tumor progression independent of otherwise necessary internal or external growth cues. This may provide cancer cells with the ability to divide indefinitely, posing a threat to the rest of the organism. LÄS MER
