  1. 21. Manufacturing of Electric Candle Preparing Industrial Production

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Leonard Hamngren; [2018]
    Nyckelord :Electric candle; manufacturing; injection moulding; surface roughness; brightness; Elektriskt stearinljus; tillverkning; formsprutning; ytjämnhet; ljusstyrka;

    Sammanfattning : Det här examensarbetet är en fortsättning på ett tidigare kandidatexamensarbete vars syfte var att bestämma form och funktion för ett elektriskt stearinljus som skulle se så verklighetstroget ut som möjligt. En prototyp av ljuset byggdes för att testa den nya tekniska lösningen. LÄS MER

  3. 22. Developing a technique for combining light and ultrasound for deep tissue imaging

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

    Författare :Meng Li; [2018]
    Nyckelord :UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Sammanfattning : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. LÄS MER

  4. 23. Detection of glass in RDF using NIR spectroscopy

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Philip Hedlund; [2018]
    Nyckelord :NIR; spectroscopy; RDF; glass; CFB; boiler; performance; losses; NIR; spektroskopi; RDF; glas; CFB; panna; prestanda; förluster;

    Sammanfattning : Purpose of this study was to investigate the possibilities of using Near-infrared (NIR) spectroscopy to detect glass in refuse derived fuel (RDF) as well as what on-line data of glass content could be used for in terms of boiler operation and performance determination. Sample configurations were done with dried RDF (to prevent mass loss due to moisture and spectroscopic disturbance) and increasing concentrations of colored soda-lime glass, total of 100 samples.

  5. 24. Unbiasing entomological kHz Scheimpflug LIDAR data

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

    Författare :Alexandra Andersson; [2018]
    Nyckelord :Entomological LIDAR; Insect detection; Wing-beat frequency; Unbiasing of analysis model; Physics and Astronomy;

    Sammanfattning : Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time. Insect observations can be distinguished from the background signal through adaptive thresholding. LÄS MER

  7. 25. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering

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

    Författare :David Frantz; [2017]
    Nyckelord :scattering media; Structured Illumination; optical Fourier filtering; Modulation Transfer Function; Monte Carlo simulation; Technology and Engineering;

    Sammanfattning : In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. LÄS MER
