  1. 1. Artificiell Intelligens inom medicinsk bilddiagnostik : En allmän litteraturstudie

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för hälsovetenskap

    Författare :Mats Rönnqvist; Magnus Johansson; [2019]
    Nyckelord :Artificial Intelligence; AI; Deep Learning; Machine Learning; CADe; CADx; Artificiell Intelligens; AI; djupinlärning; maskininlärning; CADe; CADx;

    Sammanfattning : Bakgrund: Artificiell Intelligens (AI) kommer in i vårt samhälle och våra hem i allt större utsträckning. Inom sjukvården och radiologin kan AI utgöra ett hjälpmedel för både radiologer och röntgensjuksköterskor i deras profession. LÄS MER

  3. 2. The astronomical consequences of primordial black holes

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Loke Lönnblad Ohlin; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In the radiation or early matter dominated eras of the Universe, there is a theoretical possibility for the formation of black holes (BHs). These primordial black holes (PBHs) have been thought of as a possible candidate for dark matter (DM), and an attractive one at that as it would explain DM using only baryonic physics. LÄS MER

  4. 3. Introducing a central receiver system for industrial high-temperature process heat applications : A techno-economic case study of a large-scale CST plant system in a South African manganese sinter plant

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Maria Hallberg; Elin Hallme; [2019]
    Nyckelord :Solar energy; concentrating solar thermal; CST; central receiver system; CR; HelioPod; high-temperature process heat; manganese; business case; Solenergi; koncentrerad termisk solvärme; CST; soltorn; HelioPod; högtempererad processvärme; mangan; affärsmodell;

    Sammanfattning : The objective of this thesis was to investigate the potential for introducing a concentrating solar thermal (CST) central receiver plant system based on flexible heliostats - HelioPods - to provide high-temperature process heat in industrial applications. A CST plant system was designed in MATLAB, optically simulated for three design days in the ray-tracing software Tonatiuh and further analyzed in MATLAB by interpolating the results for each hour of the year.

  5. 4. Konstruktion av drivenhet till Veritas : Konstruktionsförslag till drivenhet

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Mikkel Öhrman; [2016]
    Nyckelord :Design proposal; Konstruktionsförslag;

    Sammanfattning : During this project a mechanical design proposal has been developed for the Veritas project at Uppsala University. The Veritas resonant inelastic X-ray scattering (RIXS) spectrometer aims at becoming a world leading beamline for RIXS in the 275-1500eV range. LÄS MER

  7. 5. Carboxylated Cellulose Nanocrystals Extraction from Kraft Pulp Using Ammonium Persulfate as Low Cost Source & Sustainable Method for High Quality Flexible Packaging Bio-coating

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Gerald Perry Estavillo Marin; [2015]
    Nyckelord :affordable CNC extraction; high quality CNC; sustainable packaging; FT-IR; TEM; XRD; contact angle; transparency; haze; optical properties; food packaging; bio-packaging; bio-coating; plastics; PET film; polyethylene terephthalate; Kraft CNC; Kraft pulp; cotton CNC; oxygen barrier; nanocellulose crystals; ammonium persulfate; CNCs; cellulose nanocrystals; Chemistry;

    Sammanfattning : One of the leading challenges presented in 21st century for packaging industry is to address the growing environmental problems related to non-renewable flexible packaging. This leads to new growing interest in bio-based materials, among them cellulose nanocrystals (CNCs), which have already shown good performance in improving anti-fog and oxygen & water vapor barrier properties when applied to flexible film.
