  1. 1. 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

  2. 2. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care

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

    Author : Axel Trange; [2021]
    Keywords : ;

    Abstract : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.

    Abstract : En applikation för mobila enheter skapades för en målgrupp som bestod av barn i åldern 6–10 år. Applikationen ingick som en del av en större applikation som hette Clappen, som bestod av flera mindre applikationer. READ MORE

  4. 4. Always Look on the Positive-Definite Side of Life

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Mattias Byléhn; [2020-11-24]
    Keywords : Poisson summation; positive-definite distributions; Abel transform; Guinand’s distribution; relatively positive-definite distributions; Krein’s theorem; Krein measures;

    Abstract : This thesis concerns distributions on Rn with the property of being positive-definite relativeto a finite subgroup of the orthogonal group O(n). We construct examples of such distributionsas the inverse Abel transform of Dirac combs on the geometries of Euclidean space Rn and thereal- and complex hyperbolic plane H2, H2C. READ MORE
