  1. 1. Calibration and evaluation of the secondary sensors for the Mini-EUSO space instrument

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jonah Ekelund; [2018]
    Nyckelord :Mini-EUSO; EUSO; calibration; evaluation; near-infrared light; visible light; camera; phosphorus coating;

    Sammanfattning : The Mini-EUSO (Mini - Extreme Universe Space Observatory) is an instrument for observation of ultra-high energy cosmic rays (UHECR) from space. It is designed to observe Earth from the international space station (ISS) in the ultra-violet (UV), visible (VIS) and near-infrared (NIR) light ranges. LÄS MER

  2. 2. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

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

    Författare :Mariam Andersson; [2017]
    Nyckelord :Lidar; Scheimpflug; Time-of-Flight; Remote sensing; Atmospheric sensing; Physics and Astronomy;

    Sammanfattning : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.

  3. 3. Microsoft Kinect för utrymning i smarta byggnader

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Fredrik Pettersson; Karolina Lundh; [2017]
    Nyckelord :Microsoft Kinect; utrymning; dynamisk vägledning; rörelsemönster; rök; infrarött ljus; riskreduktion; smarta byggnader; evacuation; dynamic way-finding; movement patterns; smoke; infrared light; risk reduction; smart buildings; Technology and Engineering;

    Sammanfattning : In large and/or complex buildings, which can contain a lot of people, it’s important to ensure that evacuation in case of fire or other threats can be performed safely. In this report, the possibility to use Microsoft Kinect v2 for evacuation is examined to determine whether it can be used to provide dynamic crowd management systems and rescue services with information.

  4. 4. Corrosion initiation induced by sodium sulfate and sodium chloride particles on Cu and the golden alloy Cu5Al5Zn at simulated atmospheric conditions

    Master-uppsats, KTH/Materialvetenskap

    Författare :WEIJIE ZHAO; [2017]
    Nyckelord :atmospheric corrosion; sodium sulfate; sodium chloride; Cu5Al5Zn; Cu metal; mixed salt pre-deposition; laboratory exposure; LOM; SEM EDS; ATR-FTIR; cathodic reduction;

    Sammanfattning : Effects of sodium sulfate (Na2SO4) particle deposition on the atmospheric corrosion of copper (Cu) metal and a Cu-based alloy (Cu5Al5Zn) used in architectural applications were investigated at laboratory conditions compared with effects induced by sodium chloride (NaCl) and to some extent ammonium sulfate (NH4)2SO4 induced corrosion. Pre-deposited surfaces were exposed to repeated wet/dry conditions in a climatic chamber and the formation of corrosion products were assessed using light optical microscopy (LOM), scanning electron microscopy with elemental analysis (SEM/EDS), Fourier transform infrared techniques (FTIR microscopy) and cathodic reduction (CR).
