  2. 1. Combinatorics of solvable lattice models with a reflecting end

    Author : Linnea Hietala; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mathematics; mathematical physics; six-vertex model; eight-vertex SOS model; three-color model; reflecting end; domain wall boundary conditions; partition function; determinant formula; XYZ spin chain; alternating sign matrices; special polynomials; positive coefficients;

    Abstract : I den här avhandlingen studerar vi några exakt lösbara, kvantintegrerbara gittermodeller. Izergin bevisade en determinantformel för partitionsfunktionen till sexvertexmodellen på ett gitter av storlek n × n med Korepins domänväggrandvillkor (domain wall boundary conditions – DWBC).

  4. 2. End-of-life care in a Swedish county : patterns of demographic and social conditions, clinical problems and health care use

    Author : Eva Jakobsson; Högskolan i Skövde; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; End-of-life; end-of-life care; demographics; social conditions; health care utilization; places of death; clinical problems; turning point; Nursing; Omvårdnad; Humanities and Social sciences; Humaniora-samhällsvetenskap; end-of-life; end-of-life care; demographics; social conditions; health care utlization; places of death; clinical problems; turning point;

    Abstract : There is broad consensus in both international and national policy statements that care provided at end-of-life should be different from care provided during other periods of life. There is a need for comprehensive knowledge about the broad population of individuals who access the public health care system during the last period of life. READ MORE

  5. 3. A combinatorial description of certain polynomials related to the XYZ spin chain

    Author : Linnea Hietala; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; six-vertex model; eight-vertex SOS model; three-color model; domain wall boundary conditions; reflecting end; partition function; determinant formula; XYZ spin chain; alternating sign matrices; polynomials; positive coefficients;

    Abstract : The aim of this thesis is to study the connection between the three-color model and the polynomials q_n(z) of Bazhanov and Mangazeev. To give some background, we describe some exactly solvable, quantum integrable lattice models and their connections to each other and to other models. READ MORE

  6. 4. Gas exchange with a reflecting system for inhalational anaesthesia

    Author : Louise Walther Sturesson; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anesthetic conserving device; inhalational anaesthesia; carbon dioxide; Gas exchange;

    Abstract : In order to reduce comsumption of inhalational anaesthetsics during high flow anaesthesia a system open in regard to oxygen, nitogen and nitrous oxide, but closed to inhalational anaesthetics, was developed. This was achieved by a reflecting filter for inhalational anaesthetics made of active carbon. READ MORE

  7. 5. Sound field separation with microphone arrays

    Author : Elias Zea; Ines Lopez Arteaga; Mats Åbom; Leif Kari; Jean-Hugh Thomas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound field separation; Microphone arrays; Near-field acoustic holography; Reflecting surfaces; Railway rolling noise; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Sound field analysis is a fundamental tool in the design, manufacturing, testing and diagnosis of machines and transportation means, as well as the legislations that regulate noise levels in order to minimize environmental pollution. Customary solutions to the problem of sound field analysis are microphone array technologies such as near-field acoustic holography (NAH) and beamforming. READ MORE
