  1. 1. A Light Booster metro car for the commuting work force : Human Centric Lighting in underground transportation

    University essay from KTH/Ljusdesign

    Author : Anna Wawrzyniak; [2019]
    Keywords : Human Centric Lighting | Circadian lighting | Non-visual effects of light | Short light exposure | Urbanisation | Metro | Subway | Healthy commute | Lighting Design in underground public transportation;

    Abstract : People at northern latitudes lack an effective portion of daylight, especially in winter time, to entrain their circadian rhythm. If one belongs to the group of employees who have no time for daylight exposure and are not supplied by Human Centric Lighting (HCL) in their office, the only chance to get circadian light may be the daily commute.

  2. 2. Analysing Raman spectra of crystalline cellulose degradation by fungi using artificial neural networks

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Sebastian Hutteri; [2019]
    Keywords : Raman spectroscopy; artificial neural networks; saprotrophic fungi; cellulose; Physics and Astronomy;

    Abstract : This thesis investigates the use of artificial neural networks for classifying Raman spectra of partially degraded cellulose samples by fungal species. A multilayer perceptron configuration of 4 hidden layers and 128 hidden nodes was able to classify a set of 60 samples with an overall prediction accuracy of 0.55. READ MORE

  3. 3. Large Eddy Simulation of Turbulent Flow over a Backward-Facing Step

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Edmond Shehadi; [2018]
    Keywords : ;

    Abstract : This work studies the effect of grid resolution and subgrid scale modeling on the predictive accuracy of Large Eddy Simulation. In particular, the problems considered are: turbulent flow over a backward-facing step and fully-developed turbulent channel flow. READ MORE

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

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Meng Li; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. High energy gamma ray emission and multi-wavelength view of the AGN PKS 0537-441

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Linnéuniversitetet/Institutionen för datavetenskap (DV)

    Author : Emma Fransson; [2017]
    Keywords : astrophysics; AGN; PKS 0537-441; jet; accretion; synchrotron self compton; spectral energy distribution;

    Abstract : This thesis describes the analysis of Very High Energy (VHE) emission from the Active Galactic Nucleus PKS 0537-441. It also aims to put the results in a wider context by implementing previous work done on this source. The data chosen for the analysis is provided by the Fermi-LAT satellite and covers the energy range between 300 MeV and 300 GeV. READ MORE
