  1. 1. Families of cycles and the Chow scheme

    Författare :David Rydh; Dan Laksov; Martin Olsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Families of cycles; Chow scheme; Hilbert scheme; zero-cycles; divided powers; symmetric tensors; symmetric product; Weil restriction; norm functor; Algebra and geometry; Algebra och geometri;

    Sammanfattning : The objects studied in this thesis are families of cycles on schemes. A space — the Chow variety — parameterizing effective equidimensional cycles was constructed by Chow and van der Waerden in the first half of the twentieth century. Even though cycles are simple objects, the Chow variety is a rather intractable object. LÄS MER

  3. 2. Moisture Buffering in the Indoor Environment

    Författare :Kaisa Svennberg; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; furniture; textiles; moisture buffering; beds; indoor air; indoor environment; sorption isotherms; field measurements; definition scheme; Technological sciences;

    Sammanfattning : Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g. LÄS MER

  4. 3. Temporalitet och social ordning : en tidssociologisk diskussion utifrån vårdpersonals uppfattningar om handlingsmöjligheter i arbetet

    Författare :Anna-Liisa Närvänen; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biographical scheme; career; care work; organizational time; scope of action; socialization; social memoty; sociology of time; temporal order; temporal orientation; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The primary aim of the thesis is to develop a theoretical frame of reference concerning the significance of temporality for social order, how it is created, maintained and how it can be changed in interaction. The theoretical frame of reference is developed gradually and is considered as heuristic. Emphasis is placed on temporal orientation, i.e. LÄS MER

  7. 5. Electronic Cash and Hierarchical Group Signatures

    Författare :Mårten Trolin; Johan Håstad; Helger Lipmaa; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : I denna avhandling presenteras resultat inom två områden – elektroniska betalningar och hierarkiska gruppsignaturer. • En starkare säkerhetsdefinition för digitala pengar presenteras med syfte att användare inte ska behöva lita på banken i samma utsträckning som för äldre definitioner.
