  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

  4. 3. Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flares

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Sofia Tynelius; [2022]
    Keywords : Solar flares; the Sun; STIX; EUI; alignment; pointing;

    Abstract : Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). READ MORE

  5. 4. Estimation of dissolved organic carbon from inland waters using remote sensing data and machine learning

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lasse Harkort; [2022]
    Keywords : dissolved organic carbon; machine learning; remote sensing; inland waters; water quality; open source data; Earth and Environmental Sciences;

    Abstract : This thesis presents the first attempt to estimate Dissolved Organic Carbon (DOC) in inland waters over a large-scale area using satellite data and machine learning (ML) methods. Four ML approaches, namely Random Forest Regression (RFR), Support Vector Regression (SVR), Gaussian Process Regression (GPR), and a Multilayer Backpropagation Neural Network (MBPNN) were tested to retrieve DOC using a filtered version of the recently published open source AquaSat dataset with more than 16 thousand samples across the continental US matched with satellite data from Landsat 5, 7 and 8 missions.

  6. 5. Comparative Analysis of Real-Time Industrial Ethernet Protocols : ModbusTCP Protocol Implementation

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

    Author : Roshni Maniraj; [2022]
    Keywords : Industrial Ethernet; Communication Protocols; Real-time communication protocols; Modbus TCP; EtherNet IP; PROFINET IO; Ethernet Powerlink; EtherCAT®; CC-Link IE; Sercos III; Industriellt Ethernet; kommunikationsprotokoll; kommunikationsprotokoll i realtid; Modbus TCP; EtherNet IP; PROFINET IO; Ethernet Powerlink; EtherCAT®; CC-Link IE; Sercos III;

    Abstract : Industrial Ethernet Communication protocols for Real-Time communication is the focus of research in a variety of different industrial Applications. The subject of thesis study is a comprehensive analysis of Industrial Ethernet protocols used in safety-critical real-time environment, comparing these based on performance, safety, diagnostics and error detection features, topology preference, cost incurred and openness of the protocol.
