  1. 1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Elias Önerud; [2023]
    Keywords : Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Abstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

  3. 2. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adam Andersson; [2023]
    Keywords : Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Abstract : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. READ MORE

  4. 3. Towards reducing bandwidth consumption in publish/subscribe systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yifan Ye; [2020]
    Keywords : pub sub; 5G; MEC; data reduction; IoT.; pub sub; 5G; MEC; datareduktion; IoT.;

    Abstract : Efficient data collection is one of the key research areas for 5G and beyond, since it can reduce the network burden of transferring massive data for various data analytics and machine learning applications. Specifically, 5G offers great support for massive deployment of IoT devices, and the number of IoT devices is exploding. READ MORE

  5. 4. Atypical VRE Variability in Power System Planning and Performance: Illustrated by the case studies of Guinea-Bissau and Turkey

    University essay from KTH/Energiteknik

    Author : Albertine Potter van Loon; [2018]
    Keywords : ;

    Abstract : This study aims to identify and quantify (1) how Typical Meteorological Year (TMY)-based power systems perform when exposed to atypical variability and (2) how TMY-centric power system design differs from full variability design. A simplified least cost power system planning model, including a novel performance analysis formulation, is proposed and tested for Guinea-Bissau and Turkey, covering both main Variable Renewable Energy (VRE) technologies, solar PV and wind turbines.
