  1. 11. Optical Methods for Tympanic Membrane Characterisation : Towards Objective Otoscopy in Otitis Media

    Författare :Mikael Sundberg; Tomas Strömberg; Ton van Leeuwen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical Methods; Spectroscopy; Surface Curvature; Monte Carlo; Tympanic Membrane; Otitis Media; Medical engineering; Medicinsk teknik;

    Sammanfattning : Otitis media, which is an upper respiratory tract infection that affect the middle ear, is the second most common disease in childhood, outnumbered in prevalence only by the common cold. Diagnosis of middle ear inflammation is often performed in the primary healthcare where the normal procedure involves anamnesis and physical examination of the tympanic membranes (TM) of the patient, usually be means of otoscopy.

  3. 12. Distance Protection of Transmission Lines with High Levels of Series Compensation : A study on frequency and time domain communication independent distance protection for series compensated lines

    Författare :Md Tanbhir Hoq; Nathaniel Taylor; Jianping Wang; Claus Leth Bak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Series capacitor; Series compensation; Transmission line; Distance protection; Incremental quantity; Lissajous curve; RL model; RLC model; Seriekondensator; Seriekompensation; Transmissionslinje; Distansskydd; Inkrementell kvantitet; Lissajous-kurva; RL-modell; RLC-modell; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Series capacitors are used in electric transmission lines to increase their power transfer capacity. They compensate for the inductive reactance of the line. They offer a useful alternative to building new lines, in view of economic and environmental constraints. LÄS MER

  4. 13. Localization using Distance Geometry : Minimal Solvers and Robust Methods for Sensor Network Self-Calibration

    Författare :Martin Larsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; localization; TDOA; TOA; trilateration; multilateration; distance geometry; registration; sensor network self-calibration;

    Sammanfattning : In this thesis, we focus on the problem of estimating receiver and sender node positions given some form of distance measurements between them. This kind of localization problem has several applications, e.g. LÄS MER

  5. 14. Flexibel utbildning i gymnasieskolan : Utvidgade klassrum och minskad transaktionell distans

    Författare :Rolf Edström; Gunnar Grepperud; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; ICT; transactional distance; flexible education; autonomy; individualized instruction; upper secondary school; Pedagogik; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : During the 1990s radical reforms were effected in the Swedish school, at the same time as computerizing and the use of Internet increased considerably. The thesis discusses the dynamics and uncertainty that arise when changes and new technique appear in school and shall be combined with already ongoing works of change. LÄS MER

  7. 15. Diagnostic Methods for Composite Insulators with Biological Growth

    Författare :Andreas Dernfalk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; algae; composite insulators; Hough transform; biological contamination; outdoor insulation; digital image analysis; laser-induced fluorescence LIF ; fungi; diagnostic methods;

    Sammanfattning : Composite insulators have a number of advantages compared to conventional insulators, but the fact that they are more prone to aging is a major drawback. For instance, biological growths, like algae and fungi, have been found to colonize composite insulators, and possibly effecting the insulation performance. LÄS MER
