  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

  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. Catalytic Processes Mediated by Metal−Organic Frameworks Reactivity and Mechanistic Studies

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Vlad Pascanu; Belén Martín-Matute; Seth Cohen; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Abstract : The present thesis describes the development of heterogeneous catalytic methodologies using metal−organic frameworks (MOFs) as porous matrices for supporting transition metal catalysts. A wide spectrum of chemical reactions is covered. READ MORE

  5. 5. Aspects of a Constraint Optimisation Problem

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Johan Thapper; Peter Jonsson; David Cohen; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis we study a constraint optimisation problem called the maximum solution problem, henceforth referred to as Max Sol. It is defined as the problem of optimising a linear objective function over a constraint satisfaction problem (Csp) instance on a finite domain. READ MORE
