  1. 1. On the On-line Tools for Treatment of Deterioration in Industrial Processes

    University dissertation from Akademin för hållbar samhälls- och teknikutveckling

    Author : Christer Karlsson; Erik Dahlquist; Risto Ritala; [2008]
    Keywords : Deterioration; Industrial Processes; Sensors; Process models; Neural networks; Bayesian networks; Data reconciliation; Steam turbines; Boilers; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : For industrial processes high availability and efficiency are important goals in plant operation. This thesis presents studies and development of tools for on-line treatment of process deterioration and model and sensor errors in order to achieve these goals. READ MORE

  2. 2. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action

    University dissertation from Akademin för hållbar samhälls- och teknikutveckling

    Author : MARTIN ROSENQVIST; [2016-09-14]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenbyggnader; Dammar; Betong; Cement; Vattenabsorption; Vattenmättnadsgrad; Nedbrytning; Frostbeständighet; Spjälkning; Makroskopisk islinsbildning; Urlakning; Synergi; Hydraulic structures; Dams; Concrete; Cement; Water absorption; Degree of saturation; Deterioration; Frost resistance; Spalling; Macroscopic ice lens growth; Leaching; Synergy;

    Abstract : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. READ MORE

  3. 3. In-hospital patient safety - prevention of deterioration and unexpected death by systematic and interprofessional use of early warning scoring

    University dissertation from Anaesthesiology and Intensive Care

    Author : Gitte Bunkenborg; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient safety; Adverse event; Vital parameters; Deterioration; Early warning score; Mortality rate; Unexpected death; Clinical intervention; Adherence; Implementation; association;

    Abstract : Abstract In-hospital patient safety is at times hampered, leaving general ward patients at considerable risk of gradual, even life-threatening, deterioration. In many European clinical settings, inappropriate nursing practice of bedside monitoring and management has recently been addressed as impending to in-hospital patient safety. READ MORE

  4. 4. Non-Invasive Monitoring of Architectural Heritage

    University dissertation from Anaesthesiology and Intensive Care

    Author : Jenny Hällström; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

    Abstract : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning.

  5. 5. Mechanisms of salt frost scaling on portland cement-bound materials: studies and hypothesis

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Sture Lindmark; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deterioration; Durability; Freeze-Thaw; Frost; Salt; Mechanism; Chloride; Diffusion; Adsorption; Building construction; Cement; Concrete; Byggnadsteknik;

    Abstract : A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. READ MORE
