  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sara Muminovic; Christina Lindén; [2023]
    Nyckelord :Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Sammanfattning : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. LÄS MER

  3. 2. Use of Diffuser Fibres in the Treatment of Prostate Cancer by Interstitial Photodynamic Therapy

    Master-uppsats, Lunds universitet/Matematik LTH

    Nyckelord :photodynamic therapy; cancer treatment; matlab; diffuser fibres; biomedical; Mathematics and Statistics;

    Sammanfattning : SpectraCure AB is a start-up company aiming at treating internal solid tumours such as prostate tumours with an innovative technology called ‘Interstitial Photodynamic Therapy’. This treatment requires the use of fibres to deliver the amount of light required to activate a drug injected to the patient which leads to the destruction of the tumours. LÄS MER

  4. 3. Spektrumanalys och intensitetsundersökning av ljuskällor

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Lucas Wennerholm; Färm Magnus; [2015]
    Nyckelord :;

    Sammanfattning :  The department of Solid State Electronics develops and manufactures solar cells. Then they need a reliable method for evaluating the performance of the solar cell. One of their rigs use a halogen lamp with a power of 300W. The lamp has gone out of production and needs a replacement. LÄS MER

  7. 5. Simulation and parameter estimation of spectrophotometric instruments 

    Master-uppsats, KTH/Numerisk Analys och Datalogi, NADA

    Författare :Stefanos Avramidis; [2009]
    Nyckelord :DORT2002; Spectrophotometry; Spectrophotometric instruments; Paper optics;

    Sammanfattning : The paper and the graphics industries use two instruments with different optical geometry (d/0 and 45/0) to measure the quality of paper prints. The instruments have been reported to yield incompatible measurements and even rank samples differently in some cases, causing communication problems between these sectors of industry. LÄS MER
