  1. 1. Method for coupling modulatedscattered light from free flyinginsects to harmonics and theirrelative phases

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk statistik

    Författare :Martin Patricks; Ludvig Anderberg; [2020]
    Nyckelord :frequency estimation; phase estimation; matched phase reassignment; entomologic lidar; modulation spectroscopy; scattered light; Technology and Engineering;

    Sammanfattning : Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. LÄS MER

  2. 2. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Chen Xu; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. LÄS MER

  3. 3. Development of Spectroscopic Measurements for Raman and Thomson Scattering Diagnostics ——Applications in Combustion and Plasma

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Miaoxin Gong; [2019]
    Nyckelord :Raman scattering; Raman spectroscopy; Thomson scattering; stray light suppression; periodic shadowing; high dynamic range imaging; digital micro-mirror device; DMD; laminar flames; combustion; gas discharge; plasma; laser diagnostics; spectrometer; improved spectroscopy; spectroscopy; Physics and Astronomy;

    Sammanfattning : This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. LÄS MER

  4. 4. Implementing an Algorithm for Spectrum Extraction of Circumstellar Objects with High-Dispersion Spectroscopy

    Master-uppsats, Stockholms universitet/Institutionen för astronomi

    Författare :Marcus Karlsson; [2019]
    Nyckelord :Astronomy; Spectroscopy; Exoplanets; Circumstellar Objects; Direct Imaging;

    Sammanfattning : In this thesis project, we study the field of high-dispersion spectroscopy and methods for extracting the spectrum of circumstellar objects such as exoplanets from the combined signal of a stellar system. One of the only techniques for detecting absorption lines in exoplanetary atmospheres is to directly image a planet and record the reflected light. LÄS MER

  5. 5. I arbetet med kulturella barriärer : Utformandet av kulturkompetens i arbetet med funktionsvarierade från olika kulturella bakgrunder, en komparativ litteraturöversikt

    Kandidat-uppsats, Ersta Sköndal Bräcke högskola/Ersta Sköndal högskola/Institutionen för socialvetenskap

    Författare :Ellen Gustafsson; [2019]
    Nyckelord :culture; cultural competence; disability; immigrants; minority culture; majority culture; power; kultur; kulturkompetens; funktionsvariation; invandrare; minoritetskultur; majoritetskultur; makt;

    Sammanfattning : Kultur är något som i vardagen styr hur människor värderar, tänker, tror och tycker. Det påverkar också hur vi tar oss an ett visst problem och handskas med det. Funktionsvariation är något som existerar i hela värden men ändå är det så olikt hur vi människor väljer att bemöta det. LÄS MER
