  1. 1. Indoor VLC behaviour  with RGB spectral power distribution using simulation.

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Siva Babu Ajjapu; Sasank Reddy Lokireddy; [2021]
    Keywords : ;

    Abstract : n recent years visible light communication (VLC) has been one of the technologies overgrowing in this competitive world and breaking through the wireless transmission of future mobile communications. This VLC replaces radio frequency (RF), which has several important features like large bandwidth, low cost, unlicensed spectrum. READ MORE

  3. 2. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Jaime Marco Rider; [2019]
    Keywords : optical communications; underwater wireless; robot communications;

    Abstract : Eelume AS is a norwegian company that develops autonomous underwater vehicles. Their flagship model is an underwater snake robot that performs inspection, maintenance and repair operations. For the time being, Eelume has been using acoustic communications between their AUV's and the docking station, but it has a big drawback: bandwidth. READ MORE

  4. 3. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

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

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

    Abstract : 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.

  5. 4. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel

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

    Author : Daniel Söderström; [2016]
    Keywords : neutron detection; neutron; 10B; boron-10; nuclear physics; boron; neutron detector; scintillator; boron carbide; B4C; nuclear fuel; repository; SKB; Physics and Astronomy; Technology and Engineering;

    Abstract : The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. READ MORE

  6. 5. Performance Evaluation and Comparison of Coherent and Incoherent Receivers under Atmospheric Turbulence

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Mohamed Kazaludeen Akbar; [2014]
    Keywords : Free-Space Optical Communication FSO ; Signal to Noise Ratio SNR ; Avalanche Photodiode APD ; Probability Density Function PDF ; Cumulative Distribution Function CDF ; Bit Error Rate BER ;

    Abstract : Optical free space communication system faces the major challenge because of the atmospheric condition. Signals receive in the ground station using two different types of receivers (Coherent detection and Intensity Modulation and Direct Detection (IM/DD)). READ MORE
