  2. 1. Output feedback control : Some methods and applications

    Author : Johannes Nygren; Kristiaan Pelckmans; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : This thesis studies some output feedback control laws. Particularly, iterative learning control (ILC) and decentralized network based algorithms are studied. Applications to control of wastewater treatment plants are outlined. READ MORE

  4. 2. On H-infinity Control and Large-Scale Systems

    Author : Carolina Bergeling; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity Control; Decentralized Control; Large-Scale Systems; Infinite-Dimensional Systems;

    Abstract : In this thesis, a class of linear time-invariant systems is identified for which a particular type of H-infinity optimal control problem can be solved explicitly. It follows that the synthesized controller can be given on a simple explicit form. READ MORE

  5. 3. Microstructure and liquid mass transport control in nanocomposite materials

    Author : Christoffer Abrahamsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; magnetic alignment; permeability; colloidal gels; microgels; bond water; clay; flow; microstructure; nanocomposites; poly N-isopropylacrylamide ; porous materials; liquid mass transport; diffusion; diffusion NMR; particle aggregation; phase behavior; silica;

    Abstract : Some of the biggest problems currently facing the world are closely tied to unsolved technological challenges in the material sciences. Many materials have a porous microstructure that controls their overall properties. READ MORE

  6. 4. Conceptual and empirical issues of technological change in the health care sector : Innovation and diffusion of hemodialysis and renal transplantation

    Author : Ann Bonair; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Medical technology; innovation; diffusion; determinants of diffusion; ESRD treatment; ESRD costs; regional variations; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The present study focuses on one instance of technological change in medical practice; the innovation and diffusion of hemodialysis and renal transplantation (ESRD treatment)- two therapeutic innovations aimed at the treatment of patients suffering from chronic renal failure. The purpose of the thesis is to study the processes by which medical technology is developed imd disseminated. READ MORE

  7. 5. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels

    Author : Diana Bernin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion; gel; alginate; pulsed field gradient NMR; 19F NMR; cellulose; 1H NMR; dendrimer; biomaterial; mass transport;

    Abstract : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. READ MORE
