  1. 6. Sharp Bounds for Calderón-Zygmund Operators in a Vector-Valued Setting

    Författare :Andrei Stoica; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Calderón-Zygmund operator; martingale transform; Bellman function; dyadic Haar shift; UMD space; matrix A2 weight; weighted L2-space; Carleson embedding theorem;

    Sammanfattning : In this thesis we extend several classical results about Calderón-Zygmund operators to spaces of vector-valued functions. We first obtain bounds for the norm of dyadic Haar shift operators using a Bellman function technique, and then apply the representation theorem to obtain corresponding results for general Calderón-Zygmund operators.

  2. 7. Module categories, internal bimodules and Tambara modules

    Författare :Mateusz Stroinski; Volodymyr Mazorchuk; Jürgen Fuchs; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning :  We use the theory of Tambara modules to extend and generalize the reconstruction theorem for module categories over a rigid monoidal category to the non-rigid case. We show a biequivalence between the 2-category of cyclic module categories over a monoidal category C and the bicategory of algebra and bimodule objects in the category of Tambara modules on C .

  3. 8. Towards Secure Multipath TCP Communication

    Författare :Zeeshan Afzal; Stefan Lindskog; Anna Brunstrom; Stefan Axelsson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; network security; MPTCP; TCP; IDS; snort; edit-distance; Computer Science; Datavetenskap;

    Sammanfattning : The evolution in networking coupled with an increasing demand to improve user experience has led to different proposals to extend the standard TCP. Multipath TCP (MPTCP) is one such extension that has the potential to overcome few inherent limitations in the standard TCP. LÄS MER

  4. 9. Functional Hodrick-Prescott Filter

    Författare :Hiba Nassar; Astrid Hilbert; Alexander Meister; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inverse problems; adaptive estimation; Hodrick-Prescott filter; smoothing; trend extraction; Gaussian measures on a Hilbert space.; Mathematics; Matematik;

    Sammanfattning : The study of functional data analysis is motivated by their applications in various fields of statistical estimation and statistical inverse problems.In this thesis we propose a functional Hodrick-Prescott filter. This filter is applied to functional data which take values in an infinite dimensional separable Hilbert space. LÄS MER

  5. 10. To work or not to work in an extended working life? Factors in working and retirement decisions

    Författare :Kerstin Nilsson; Avdelningen för arbets- och miljömedicin; Sveriges lantbruksuniversitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ageing; older worker; retirement planning; retirement decision; motivation; meaningful activity; social inclusion; macro; meso; micro; work environment; working life; work ability; work injury; health; public health; diagnosed disease; self-rated health; organisation; basic premises for work; hardware in work; software in work; age; Success and failure factors; folkhälsa; demographic shifts; healthy ageing; healthy work places; retirement; successful ageing; occupational environment; Occupational medicine; work motivation; demografy; men and women;

    Sammanfattning : In most of the industrialised world, the proportion of older and retired people in the population is continuously increasing. This will have budgetary implications for maintaining the welfare state, because the active working section of the population must fund the non-active and old population. LÄS MER
