  1. 1. Approach for frequency response-calibration for microphone arrays

    University essay from KTH/Hälsoinformatik och logistik

    Author : Jacob Drotz; [2023]
    Keywords : microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

    Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

  3. 2. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

  4. 3. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    University essay from KTH/Kemiteknik

    Author : Gisela Engström; [2022]
    Keywords : Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Abstract : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. READ MORE

  5. 4. Evaluation of Data-Driven Gating for 68Ga-ABY-025 PET/CT in Breast Cancer Patients

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alain-Klaus Ncuti Nobera; [2020]
    Keywords : Data-driven gating; Motion Correction; Affibody molecule; ABY-025; Breast Cancer; HER2; PET CT;

    Abstract : Respiratory motion during PET acquisition degrades image quality. It is mainly the area around the thorax and abdomen which is affected. External devices do provide respiratory gating solutions but are time-consuming to set up on patients and may not always be available. READ MORE

  6. 5. Cascade Matched Filtering & Adaptive Threshold Techniques on Optical Tracking Signals under AWGN

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Sebastian Elm; [2019]
    Keywords : Technology and Engineering;

    Abstract : A cascade matched filtering (CMF) approach is purposed for filtering rectangular pulse train tracking signals, with known signal characteristics, in an embedded signal detection unit. Two adaptive detection algorithms are suggested, adapting to alterations in noise signal characteristics, due to environmental changes. READ MORE
