  1. 21. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays

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

    Author : Jesper Brunnström; [2021]
    Keywords : Active noise control; Secondary path modelling; Spatial; Adaptive filter; Multichannel; Least mean squares; Aktiv brusreducering; Sekundärvägsmodellering; Spatial; Adaptiv Filtrering; Multikanal; Minsta kvadratmetoden;

    Abstract : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. READ MORE

  3. 22. Computer vision for automatic opening of fuming slag-furnace

    University essay from Umeå universitet/Institutionen för fysik

    Author : Hannes Burman; [2021]
    Keywords : Computer vision;

    Abstract : This thesis covers the implementation of visual algorithms for a robot that is to operate at a smelter furnace. The goal is for the robot to replace a human in the opening, closing and flow regulation process as danger can arise when 1300°C slag flows out of the furnace. READ MORE

  4. 23. Adaptive Frequency Resolution for Downlink Beamforming in 5G NR

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Johanna Bengtsson; [2021]
    Keywords : beamforming; MIMO; 5G; 5G NR; Technology and Engineering;

    Abstract : As the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. READ MORE

  5. 24. A Phantom Based Comparison of Image Segmentation Algorithms for Adaptive Functional Volume Determination of the Thyroid Gland using SPECT

    University essay from Stockholms universitet/Fysikum

    Author : Henrik Berg; [2021]
    Keywords : Hyperthyroidism; Nuclear Medicine; SPECT; Functional Volume; Phantom Study; Adaptive Image Segmentation; Thresholding; Region Growing;

    Abstract : Background One of the most used treatments for hyperthyroidism, is therapy with radioactive iodine (131I), which is accumulated in the thyroid gland. To determine the activity of 131I to be administered for a certain absorbed dose, the volume of the gland is of great importance but the historically used methods for estimating the functional volume of the gland are based on large approximations.

  6. 25. Dopamine Waves Lead to a Swift and Adaptive Reinforcement Learning Algorithm

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

    Author : Gergö Gömöri; [2021]
    Keywords : Reinforcement Learning; Dopamine; Basal Ganglia; Successor Representation; förstärkningsinlärning; dopamin; basala ganglierna; successionsrepresentation;

    Abstract : Accumulating evidence suggests that dopaminergic neurons show significant task-related diversity. Curiously, dopamine concentration and dopamine axon activity show spatio-temporal wave patterns in the dorsal striatum. READ MORE
