  1. 6. Weather Influence on LiDAR Signals using the Transient Radiative Transfer and LiDAR Equations

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Marcus Hedlund; [2020]
    Keywords : Radiative transfer; LiDAR; Transient radiative transfer;

    Abstract : The ongoing development of self driving cars requires accurate measuring devices and the objective of this thesis was to investigate how di↵erent weather will affect one of these devices, known as a LiDAR. A LiDAR uses pulsed laser light to measure the distance to an object. READ MORE

  5. 9. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jaka Perovšek; [2018]
    Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

    Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE

  6. 10. Use of Diffuser Fibres in the Treatment of Prostate Cancer by Interstitial Photodynamic Therapy

    University essay from Lunds universitet/Matematik LTH

    Author : Shaineze Afir; [2018]
    Keywords : photodynamic therapy; cancer treatment; matlab; diffuser fibres; biomedical; Mathematics and Statistics;

    Abstract : 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. READ MORE
