  1. 16. 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. 17. Automatic Image Based Positioning System

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Omsri Kumar Aeddula; [2017]
    Nyckelord :Center of Mass; Gradient; Automatic Positioning System; Background Subtraction;

    Sammanfattning : Position of the vehicle is essential to navigate the vehicle along a desired path without any human interference. Global Positioning System (GPS) loses significant power due to signal attenuation caused by construction buildings. A good positioning system should have both good positioning accuracy and reliability. LÄS MER

  4. 18. Flight Pattern Analysis : Prediction of future activity to calculate the possibility of collision between flying objects and structures

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :André bei der Hake; [2016]
    Nyckelord :Motion Detection; Background Subtraction; Image Segmen- tation; Morphology; Blob-Analyse; Statistical Model; Prediction Of Future Activity; Kalman-Filter;

    Sammanfattning : This report shows that a reliable motion detection is needed to make an accurate prediction of future activity. Several experiments are carried out to obtain information about the object ́s behaviour and the best settings for the motion detection. LÄS MER

  5. 19. Measurements of radioactivity in plant and soil samples taken near a nuclear power plant

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Gjertrud Louise Langaas; [2016]
    Nyckelord :;

    Sammanfattning : This project is a study of six soil and vegetation samples taken near the nuclear power plant at Ringhals, Sweden. The purpose was to detect any signs of radioactivity in the soil and vegetation originating from the plant, while simultaneously giving insight on the advantages and limitations of using equipment from the radioecology lab at the Swedish University of Agricultural Sciences.

  7. 20. Increasing Sound Quality using Digital Signal Processing in a Surveillance System

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Gustav Johnsson Henningsson; Patrik Siljeholm; [2016]
    Nyckelord :Digital Signal Processing Noise reduction Equalizer Microphone Spectral subtraction Surveillance Audio Wiener filter; Technology and Engineering;

    Sammanfattning : Hearing is our second most important sense. The main focus of a surveillance camera is obviously the video but the audio shouldn't be neglected. It is possible to hear what the camera can't see and what is said in a conversation can't be showed in a video. Therefore there are good reasons to always try and achieve the best audio possible.
