  1. 1. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Arieh Cohen; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Abstract : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. READ MORE

  4. 4. 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

  5. 5. 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
