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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Roshni Maniraj; [2022]
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Analysis of the Stratospheric Aerosol Load After the 2019 Raikoke Eruption

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Felicia Carlborg; [2021]
    Nyckelord :Volcanic Climate Impact; Raikoke; CALIPSO; Satellite; Stratospheric Aerosols; Radiative Forcing; Aerosol Optical Depth; Physics and Astronomy;

    Sammanfattning : The stratospheric aerosol load after the eruption of Raikoke in 2019 have been analysed with satellite data from the CALIPSO satellite. The goal was to see how much the stratospheric aerosol load increased due to the Brewer Dobson circulation, and further, how this affected the stratospheric aerosol optical depth (AOD), and the corresponding radiative forcing (RF).

  4. 3. Planetary Boundary Layer Height Variations Over the Tibetan Plateau in Relation to Local Climate Variables and Large-Scale Circulation

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Nils Slättberg; [2020-09-09]
    Nyckelord :;

    Sammanfattning : The lowest layer of the Earth's atmosphere, the planetary boundary layer (PBL), may reach extremely high above the Tibetan Plateau (TP). Moreover, the TP is a hotspot region for climate interactions, exerting far-reaching in uences on atmospheric conditions. LÄS MER

  5. 4. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Ludvig Sjöberg; [2019]
    Nyckelord :Weather Research and Forecasting Model; Large Eddy Simulation; Microscale Meteorology;

    Sammanfattning : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.

  7. 5. Automated IV-measurements for solar panels in stratospheric conditions

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Lowe Lundin; Dag Lindgren; Lowe Erickson; [2018]
    Nyckelord :;

    Sammanfattning : In this project an automated IV-measurement circuit able towithstand stratospheric conditions was developed. It was made to bepart of an experiment which will be executed at an altitude ofapproximately 27 km. The IV-measurements aim to conclude the powergenerated by the solar panels during the flight.
