    Abstract : Popular Abstract in Swedish Stärkelse och cellulosa är naturligt förekommande polymerer av glukos. Dessa polymerer har varit viktiga resurser för människan genom historien. Stärkelse är en viktig näringskälla som det finns rikligt av i sädessorter och potatis. Cellulosa är en viktig komponent i byggmaterial (t. READ MORE

  3. 3. Logics of Knowledge and Cryptography Completeness and Expressiveness

    University dissertation from Stockholm : KTH

    Author : Mika Cohen; KTH.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; epistemic logic; first-order logic; formal cryptography; static equivalence; security protocols; BAN logic; multi-agent system; completeness; logical omniscience problem; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : An understanding of cryptographic protocols requires that we examine the knowledge of protocol participants and adversaries: When a participant receives a message, does she know who sent it? Does she know that the message is fresh, and not merely a replay of some old message? Does a network spy know who is talking to whom? This thesis studies logics of knowledge and cryptography. Specifically, the thesis addresses the problem of how to make the concept of knowledge reflect feasible computability within a Kripke-style semantics. READ MORE

  4. 4. Compactifying locally Cohen-Macaulay projective curves

    University dissertation from Stockholm : KTH

    Author : Morten Hønsen; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cohen-Macaulay compactification; curves; algebraic space; MATHEMATICS Algebra; geometry and mathematical analysis Algebra and geometry; MATEMATIK Algebra; geometri och analys Algebra och geometri;

    Abstract : We define a moduli functor parametrizing finite maps from a projective (locally) Cohen-Macaulay curve to a fixed projective space. The definition of the functor includes a number of technical conditions, but the most important is that the map is almost everywhere an isomorphism onto its image. READ MORE

  5. 5. Knowledge Closure and Knowledge Openness : A Study of Epistemic Closure Principles

    University dissertation from Stockholm : Department of Philosophy, Stockholm University

    Author : Levi Spectre; Stockholms universitet.; [2009]
    Keywords : HUMANIORA; HUMANITIES; knowledge; principle of epistemic closure; knowledge openness; evidence; epistemic principles; skepticism; fallibilism; principles of evidence; evidence openness; dogmatism; safety; chance; Bayesianism; Carnap; Cohen; Dretske; Hawthorne; Hempel; Kripke; Nozick; Pagin; Vogel; Williamson; HUMANITIES and RELIGION History and philosophy subjects Philosophy subjects Theoretical philosophy; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Filosofiämnen Teoretisk filosofi; Theoretical Philosophy; teoretisk filosofi;

    Abstract : The principle of epistemic closure is the claim that what is known to follow from knowledge is known to be true. This intuitively plausible idea is endorsed by a vast majority of knowledge theorists. There are significant problems, however, that have to be addressed if epistemic closure – closed knowledge – is endorsed. READ MORE
