  1. 1. LDPC DropConnect

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

    Author : Xi Chen; [2023]
    Keywords : Bayesian approach; Machine learning; Coding theory; Measurement uncertainty; Algorithms; Bayesiansk metod; Maskininlärning; Kodningsteori; Mätosäkerhet; Algoritmer;

    Abstract : Machine learning is a popular topic that has become a scientific research tool in many fields. Overfitting is a common challenge in machine learning, where the model fits the training data too well and performs poorly on new data. READ MORE

  3. 2. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

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

    Author : Jens Eilers Bischoff; [2022]
    Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

  4. 3. Calculating Minimum Detectable Activity for a moving scintillator detector using real-time speed measurement : Implementing a monitoring system to improve accuracy of surface contamination measurement systems

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

    Author : Artur Amcoff; Oscar Persson; [2021]
    Keywords : Minimum Detectable Activity MDA ; Surface contamination; ISO 11929; Alpha α radiation; Beta β radiation; Detection limit; Counting efficiency; Minsta detekterbara aktivitet; Ytkontaminering; ISO 11929; Alfa α strålning; Beta β strålning; Detektionsgräns; Radioaktiv mäteffektivitet;

    Abstract : Surface contamination occurs in nuclear facilities, something that is important to detect easily and efficiently. Using today’s methods to detect nuclear surface contamination may cause certain inconsistencies as the human operator is solely trusted to keep the detector at the correct distance and move it at the correct speed.

  5. 4. Evaluation of Dissolved Air Flotation for Water Purification: With Focus on Floc Characteristics and PFAS

    University essay from KTH/Kemiteknik

    Author : Ludwig Löf; [2021]
    Keywords : Water treatment; Sedimentation; Flotation; PFAS; Zeta potential; Vattenbehandling; Sedimentering; Flotation; PFAS; Zeta potential;

    Abstract : I detta projekt har experiment utförts med mål att förse kommunalförbundet Norrvatten med data som kan användas som underlag för beslutsfattande angående om deras fällningslinjer i vattenreningsprocessen ska köras i flotation eller sedimentering. För detta ändamål har koncentrationen av poly- och perfluorerade alkylsubstanser (PFAS) samt karaktär av agglomererade partiklar (flockar) undersökts och jämförts mellan fällningslinjer som körs i olika konfigurationer.

  6. 5. Ionospheric Models for GNSS Measurements

    University essay from KTH/Fastigheter och byggande

    Author : Carolina Offenbacher; Ellen Thornström; [2020]
    Keywords : GNSS; ROTI; TEC; ionospheric turbulence; GNSS; ROT; TEC;

    Abstract : There is an increasing demand for higher precision when using Global Navigation Satellite Systems, GNSS, for positioning. The measurement uncertainty depends on multiple factors and one of them is the ionosphere. READ MORE
