  1. 1. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Nyckelord :high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Sammanfattning : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. LÄS MER

  3. 2. Stilles Design : A pursuit for creating conditions for openness

    Master-uppsats, Konstfack/Industridesign

    Författare :Heinrich Ehnert; [2018]
    Nyckelord :Silence; Stillness; Parametric Design; Sound; Noise; Soundscape; Interaction; Material; Wood; Machine; Device; Contingency; Transience; Frequency; Fourier Transform; Arduino;

    Sammanfattning : The present work represents both: a design proposal and a proposal for design.Today we are exposed to more and louder noise than ever before in all areas of human life, which alters the environment, our health and the quality of social interaction to the worse. LÄS MER

  4. 3. Hur påverkas stammande personers talflyt av förstärkt hörselåterkoppling?

    Magister-uppsats, Logopedi

    Författare :Sara Johansson; Sofia Walker Westerlund; [2010]
    Nyckelord :stuttering; enhanced auditory feedback; frequency altered feedback; stamning; förstärkt hörselåterkoppling; frekvensförändrad hörselåterkoppling;

    Sammanfattning : I denna studie undersöktes effekten av förstärkt hörselåterkoppling (enhanced auditoryfeedback, EAF) på observerbar stamning och upplevd känsla av talflyt hos vuxna personer som stammar. Så vitt vi vet finns inga tidigare studier av effekten av förstärkt hörselåterkoppling vid stamning. LÄS MER
