  1. 1. Research and Testing of an Electromechanical solution for Vibration Assisted Drilling of Aerospace Materials

    University essay from Uppsala universitet/Solcellsteknik

    Author : Jonathan Nordenholm; [2020]
    Keywords : vibration; drilling; chips; aerospace; advanced drilling unit;

    Abstract : This thesis considers vibration drilling in aerospace materials. The tolerances of the drilled holes in aerospace industry are very low since hole quality is an important factor. Conventional methods of drilling create long ribbon formed chips that increases the heat formation and decreases the hole quality. READ MORE

  2. 2. Implementation of Spectrum Analysis Functionality for IQ-Signal.

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Gedion Biredaw Anbessa; [2020]
    Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

    Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

  3. 3. Hand Gesture Classification using Millimeter Wave Pulsed Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Eda Dagasan; [2020]
    Keywords : Hand Gesture Classification; Millimeter Wave Radar; Statistical Signal Processing; Time-Frequency Analysis; Room Impulse Response Estimation; Sparse Dictionary Learning; Classification; Supervised Learning; Convolutional Neural Networks; k-Nearest Neighbor; Mathematics and Statistics;

    Abstract : Millimeter wave pulsed radar has found many applications, among them hand gesture sensing, which this work has as purpose. This application has already shown good potential, [1], and here in this work robustness aspects are taken into account. READ MORE

  4. 4. Machine Learning for FMCW Radar Interference Mitigation

    University essay from Lunds universitet/Matematisk statistik

    Author : Jessica Nilsson; Ludvig Hassbring; [2020]
    Keywords : FMCW radar; interference mitigation; convolutional neural network; Mathematics and Statistics;

    Abstract : Frequency Modulated Continuous Wave radar is used for object detection and localization, e.g., for surveillance purposes or for automotive systems. The amount of radars is increasing, which leads to an increasing amount of radar interference. READ MORE

  5. 5. Attenuation AND awareness? : Designing a method for measuring accuracy and certainty of sound identification when wearing a HPD

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Markus Ahlberg; [2020]
    Keywords : Industrial design engineering; method design; sound identification; situational awareness; hearing protection devices; noise pollution; level-dependent function; Teknisk design; metoddesign; ljudidentifikation; situationsmedvetenhet; hörselskydd; buller; bullerföroreningar; nivåberoende funktion;

    Abstract : Noise pollution is widespread in today’s society, from traffic to industrial sources, and many people are confined to unhealthy acoustic environments through their employment. When noise cannot be eliminated at the sound source, the protective measure is usually to equip the employee with hearing protection devices (HPDs), e.g. READ MORE
