  1. 6. Vibration analysis of a fast response brushless excitation system

    University essay from Uppsala universitet/Elektricitetslära

    Author : Emma Pålsson; [2019]
    Keywords : vibrations; frequency analysis; FRBE; controlled rectification; hydropower; exciter; generator; fast response;

    Abstract : The aim of this study is to measure and analyze vibrations on a fast response brushless exciter (FRBE) at a real hydropower plant and identify vibration origins through frequency analysis. Moreover, the observed vibrations are evaluated in relation to generator vibration standards and estimated tangential eigenfrequencies of the studied FRBE. READ MORE

  3. 7. Individualized closed-loop anesthesia through patient model partitioning

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Ylva Wahlquist; [2019]
    Keywords : Technology and Engineering;

    Abstract : This master thesis project proposes methods for individualizing closed-loop controlled anesthesia. One of the largest challenges with closed-loop anesthesia is the variation between patients in the sensitivity to the anesthetic drug, here propofol. READ MORE

  4. 8. Technical Feasibility Study of an IGBT-based Excitation System

    University essay from Uppsala universitet/Elektricitetslära

    Author : Johan Frisk; [2017]
    Keywords : Cabinet design; inverter cabinet; IGBT; excitation system; EMC; electrical connection; Skåpdesign; IGBT; magnetiseringssystem; EMC; elektrisk anslutning;

    Abstract : This thesis aims to design a cabinet to house some of the required hardware to realize a 1000 A IGBT inverter controlled static excitation system. In the thesis practical design considerations are identified and solved. The suggested excitation system requires a cabinet to house the inverters. READ MORE

  5. 9. Hardware Control of a Near Infrared Fluorescence System : LabVIEW Programming and Evaluation

    University essay from Linköpings universitet/Biomedicinsk instrumentteknik

    Author : María Martha de la Paz Velasco Santoscoy; [2016]
    Keywords : Near-infrared; indocyanine green ICG ; biomedical optics; fluorescence; spectroscopy; lasers.;

    Abstract : Indocyanine green (ICG) is a fluorescent dye used as an indicator in medicine and surgery. The maximum absorption wavelength of ICG is at 785 nm, while the maximum emission is around 820 nm. ICG is nontoxic and is rapidly excreted into the bile. READ MORE
