  2. 16. Organizing Product Development - Formalizing the Informal in Interdependent Knowledge Work

    Author : Mats Lundqvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; task interdependence; product development management; self-organizing work; organizational knowledge creation; efficiency and effectiveness;

    Abstract : This thesis is concerned with organizing product development in the setting of established manufacturing firms. Product development practices have undergone major changes during the past decade. Companies increasingly see product development as a key tool for competitiveness. READ MORE

  4. 17. Optical Phase Conjugation and All-Optical Demultiplexing using Four-Wave Mixing in Dispersion Shifted Fibers

    Author : Per Olof E Hedekvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion compensation; nonlinear fiber optics; high-speed communication; four-wave mixing; parametric amplification; noise figure; wavelength conversion; optical phase conjugation; all-optical demultiplexer; mid-span spectral inversion;

    Abstract : This thesis deals with two applications of four-wave mixing in optical dispersion-shifted fibers; optical phase conjugation and all-optical switching. The work is a part of an effort to study the upgradability of the existing fiber plant, which is of large economic interest. READ MORE

  5. 18. Haemodialysis Treatment Monitored On-line by Ultra Violet Absorbance

    Author : Fredrik Uhlin; Lars-Göran Lindberg; Martin Magnusson; Bernd Stegmayr; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dialysis; Hemodialysis; Proteins; Metabolism; Renal dialysis; Ultraviolet spectrophotometry; Urea; Uremia; Kidney diseases; Njursjukdomar;

    Abstract : This thesis describes and evaluates an optical method utilizing ultra violet (UV) absorbance for on-line monitoring of haemodialysis treatment. Increased efficiency of haemodialysis treatment is considered to correlate to decreased morbidity and mortality when urea clearance (Kt/V) is elevated. READ MORE

  6. 19. In the wake of a bird - Quantifying aerodynamic performance of avian flight

    Author : Marco Klein Heerenbrink; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal flight; flight performance; gliding; powered flight; wing morphology; aerodynamics; biomechanics; birds; jackdaw; Corvus monedula; wind tunnel; PIV;

    Abstract : Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. READ MORE

  7. 20. Mitigation of Rotating Vortex Rope in a Hydro Turbine using a Guide Vane System

    Author : Jesline Joy; Michel Cervantes; Mehrdad Raisee; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Using renewable energy, such as water or wind, to produce electricity has been proven highly effective in Sweden. The ability of these renewable resources to make clean output energy counters the adversities caused by non-renewable resources. Amongst these, hydro turbines are one of the most preferred methods for generating electricity from water. READ MORE
