  1. 11. Creation of a Finite Element Model andSystem Analysis for the Low and HighFrequency Cryogenic Telescopes of theSpace Mission LiteBIRD

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Matias Rittatore Texeira; [2022]
    Keywords : FEM; FEA; mesh model; CMB; IRAP;

    Abstract : The Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection (LiteBIRD) is a Japan Aerospace Exploration Agency (JAXA)-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the early Universe, through the measurement of their imprint onto the polarization of the Cosmic Microwave Background (CMB). It is an international collaboration, with European Union (EU) operations being coordinated by France. READ MORE

  3. 12. The Dynamics of Neural Networks Expressivity with Applications to Remote Sensing Data

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

    Author : Hui Zhang; [2022]
    Keywords : Neural Networks; Linear Regions; Expressivity; Initialization; Remote Sensing; Neurala nätverk; linjära regioner; uttrycksfullhet; initialisering; fjärranalys;

    Abstract : Deep neural networks (DNN) have been widely demonstrated to be more powerful than their shallower counterparts in a variety of computer vision tasks and remote sensing applications. However, as many techniques are based on trial-and-error experiments as opposed to systematic evaluation, scientific evidence for the superiority of DNN needs more theoretical and experimental foundations.

  4. 13. Dwarf Galaxies in the Galactic Potential as probes of its internal structure

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Arn Marklund; [2022]
    Keywords : Numerical integration; Stellar Streams; Dwarf Galaxies; Dark Matter; Physics and Astronomy;

    Abstract : Satellite galaxies on bound orbits around the Milky Way (MW) are constantly subject to tidal forces from the MW. If the tidal forces are large enough, they may strip the outermost stars of the satellite, that in turn distribute themselves in long elongated stellar streams. READ MORE

  5. 14. Development of Software Library for Open Source GNSS Receiver with Focus on Physical Layer Signal Processing

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Vitalijs Kudrins; [2021]
    Keywords : GNSS; GPS; Galileo; GNSS Signal; Rust library; Engelska; English;

    Abstract : In order to directly interface with signal broadcast by global navigation satellite systems (GNSS) – such as GPS or Galileo – for the purpose of calculating location, a potential user is required to extract great amount of information from interface control documents (ICD) as well as build custom software tools to process this information. This is time consuming and inefficient. READ MORE

  6. 15. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ines Júlio Alfredo; [2021]
    Keywords : Sentinel 2; Vegetation Indices; Ground Sensors; Drought and Mire; Earth and Environmental Sciences;

    Abstract : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. READ MORE
