  2. 1. Immobilization and Interaction of Biomolecules at the Solid-Liquid Interface : Applications to Solid-Phase Analytical Techniques

    Author : Ulf Jönsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein immobilization; silica; Immunoglobulins; Protein A; Fibronectin; chemical-vapour deposition; silane; ellipsometry; radiolabeling; contact-angle measurement; solid-phase analytical techniques;

    Abstract : The development of solid-phase-analytical techniques based on surface-concentration-measuring devices requires a stable and reproducible immobilization of biomolecules on well-characterized solid surfaces. This study reports on the immobilization of Immunoglobulin G, Protein A and Fibronectin on chemically modified silica surfaces. READ MORE

  4. 2. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules

    Author : Mats Jönsson; Ulf Lindberg; Bertil Hök; Johan Nilsson; Uppsala universitet; []
    Keywords : Engineering physics; sensor; micro; dielectrophoresis; impedance; electrode; beads; cell; flow; bacteria; microfabrication; biosensor; electrocapture; microfluidic; planar; Lab on chip; µTAS; micro total analysis system; QCM; dispersion; field-flow fractionation; ITO; design; fabrication; Teknisk fysik;

    Abstract : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. READ MORE

  5. 3. Control and Analysis of Pulse-Modulated Systems

    Author : Stefan Almér; Ulf Jönsson; Gilead Tadmor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pulse-width modulation; Periodic systems; Stability analysis; Harmonic analysis; Lyapunov methods; Dynamic phasors; Harmonic transfer function; Switched mode power converters; Sampled data modeling; H-infinity synthesis; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. READ MORE

  6. 4. A Structure Utilizing Inexact : Primal-Dual Interior-Point Method for Analysis of Linear Differential Inclusions

    Author : Janne Harju Johansson; Anders Hansson; Ulf Jönsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Optimization; systems theory; Automatic control; Reglerteknik;

    Abstract : The ability to analyze system properties for large scale systems is an important part of modern engineering. Although computer power increases constantly, there is still need to develop tailored methods that are able to handle large scale systems, since sometimes standard methods cannot handle the large scale problems that occur.
