  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. Investigation of current sensing techniques for a high bandwidth application : Focusing on Hall-Current Sensing

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

    Author : Enric Ametller; [2023]
    Keywords : Current sensing; High bandwidth; Inverter; Hall-sensors; Strömavkänning; Hög bandbredd; Inverter; Hall-sensorer;

    Abstract : With the ongoing surge in electrification within the automotive industry, the demand for high-power inverters is steadily on the rise. Furthermore, these inverters are now expected to handle increased power loads while maintaining enhanced efficiency. READ MORE

  4. 3. Skattning av HGV och stamvolym med data från stereomatchade drönarbilder genom befintliga modeller från Skogliga grunddata

    University essay from SLU/Dept. of Forest Resource Management

    Author : Erik Forslöw; [2023]
    Keywords : drönare; stereofotogrammetri; skogliga grunddata; skogsbruksplanläggning;

    Abstract : Inom den svenska skogsbruksplanläggningen sker idag datainsamlingen traditionellt med subjektivt fördelade relaskopsytor. Den subjektiva mätningen varierar mellan och inom planläggare och har generellt ett relativt medelfel (rRMSE) på 9 % för grundytevägd medelhöjd (HGV) och 15–20 % for volym/ha. READ MORE

  5. 4. Effects of summer peaks on brown trout and Atlantic salmon growth and survival in hydropower-regulated Gullspång River

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Oscar Hallberg; [2023]
    Keywords : hydropeaking; hydropower; fish; salmon; salmo salar; salmo trutta; summer; survival; growth; parr; fry; korttidsreglering; vattenkraft; salmonid; salmo salar; salmo trutta; tillväxt; överlevnad; lax; öring;

    Abstract : Daily demands for electrical power are met through sub-daily release of turbined water in the form of hydropeaking. Hydropeaking’s changes to stream flow are listed as a threat to biodiversity in river ecosystems as it causes rapid habitat alteration such as increased depth and velocity, affecting the species living downstream.

  6. 5. Robust Multi-Modal Fusion for 3D Object Detection : Using multiple sensors of different types to robustly detect, classify, and position objects in three dimensions.

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

    Author : Viktor Kårefjärd; [2023]
    Keywords : Computer Vision; 3D Object Detection; Multi-Modal Fusion; Deep Learning; Datorseenden; 3D-objektdetektion; Multimodal fusion; Djupinlärning;

    Abstract : The computer vision task of 3D object detection is fundamentally necessary for autonomous driving perception systems. These vehicles typically feature a multitude of sensors, such as cameras, radars, and light detection and ranging sensors. READ MORE
