  1. 21. Methods of self-interference cancellation in full duplex telecommunication systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Henrik Erlandsson; Viktor Sköldheden; [2021]
    Keywords : telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE

  3. 22. Dynamic Modelling of the KTH Roller Rig

    University essay from KTH/Spårfordon

    Author : Daniele Mario Fraschini; [2021]
    Keywords : rail vehicle dynamics; roller rig; scaling; track irregularities; validation; modelling; spårfordons dynamik; rullrigg; nedskalning; spårlägesfel; validering; modellering;

    Abstract : The Rail Vehicle Research group at Kungliga Tekniska Högskolan (KTH) is on the path to design and build a scaled test rig called roller rig for research and educational purposes. A roller rig is a device simulating the track with rollers on which the test subject (a wheelset, bogie or even a full vehicle) canbe placed. READ MORE

  4. 23. Energy and Circadian Assessment of a Combination Between Integrative Lighting and Daylight Harvesting

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Ribhi Attar; Omar Al Mawla; [2021]
    Keywords : ALFA; Circadian Entrainment; Correlated Colour Temperature; Cortisol; Daylighting; Daylight Harvesting; Energy efficiency; Integrative lighting; Intrinsically photosensitive retinal ganglion cells; Melatonin; Melanopic Lux; Photopic Lux; Spectral Power Distribution; Technology and Engineering;

    Abstract : This study deals with the health and wellbeing of humans who work in offices as well as the energy use for the lighting. The focus is on how integrative lighting and daylight harvesting can be combined in an attempt to reduce the energy consumption while still eliciting a circadian response for the workers. READ MORE

  5. 24. Soil organic carbon prediction using Sentinel-2 data and the LUCAS topsoil database

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Philipp Hansen; [2020]
    Keywords : Sentinel-2 LUCAS topsoil database Soil organic carbon mapping Multispectral data; Earth and Environmental Sciences;

    Abstract : Its carbon sink potential as well as soil fertility benefits make organic carbon a soil variable for which reliable quantification methods are sought. This thesis work aims at investigating the possibility of adapting a large soil spectral library to build models for SOC predictions with remotely sensed, multispectral data. READ MORE

  6. 25. Gamma-ray emission and Synchrotron Self-Compton modelling of the macrolensed Quasar PKS 1830-211

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

    Author : Pierre Ohlsson; [2020]
    Keywords : Gamma-ray;

    Abstract : The objective of this thesis is to retrieve Light Curves, Spectral Models, Spectral Maps, and to geta Spectral Energy Distribution (SED) plot, for the source of PKS1830-211. Finally, also to do amodelling of the whole SED coming from the source with the JetSet software. Which will then becompared to a previous modelling done by A. A. READ MORE
