  1. 1. Vibration-Based Terrain Classification for an Autonomous Truck

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

    Author : Lucas Lovén; [2022]
    Keywords : Autonomous vehicles; machine learning; surface identification; obstacle identification; signal processing; time series classification; Autonoma fordon; maskininlärning; detektering av underlag; detektering av hinder; signalhantering; tidsserie klassifiering;

    Abstract : This thesis is focused on developing vibration based terrain classification for an autonomous mining truck. The goal is to classify between good and bad gravel roads as well as good and bad asphalt roads. Current literature within vibration based terrain classification has been focused to a great extent on smaller research vehicles. READ MORE

  3. 2. Experimental acceleration Measurements and Finite Elements Modeling

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Ibrahim Alnimairi; Salim Arrabi; [2021]
    Keywords : signal processing. PSD; mode shapes; Mdof; Sdof; PSDT-SVD; finite element modelling;

    Abstract : Heavy crushing machines under their production shifts, creates various levels of vibration, noise and dynamic forces which can be transferred to other parts of the industrial unit. Such kind of factors applies continuous forces on machine parts which can cause gradual fatigue, creep and eventually failure of machine. READ MORE

  4. 3. Automatic Control of a Window Blind using EEG signals

    University essay from Högskolan Kristianstad/Avdelningen för datavetenskap

    Author : Marijana Teljega; [2018]
    Keywords : NeuroSky; EEG signal processing; Extract Features; Classification; ThinkGear library; BCI;

    Abstract : This thesis uses one of Brain Computer Interface (BCI) products, NeuroSky headset, to design a prototype model to control window blind by using headset’s single channel electrode. Seven volunteers performed eight different exercises while the signal from the headset was recorded. READ MORE

  5. 4. Peak to Average Ratio Reduction in Wireless OFDM Communication Systems

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : KAMRAN HAIDER; [2006]
    Keywords : PAR; OFDM; Active-Set; Tone reservation; PSD constraint;

    Abstract : Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in today’s cellular systems. By going to higher bandwidth the (for low bandwidth) flat fading radio channel becomes frequency selective and time dispersive. READ MORE

  6. 5. Digital Implementation of a Laser Doppler Perfusion Monitor

    University essay from Institutionen för systemteknik

    Author : Ola Larsson; [2006]
    Keywords : Digital Laser Doppler DSP Perfusion FFT PSD Perimed;

    Abstract : Under 20 års tid har Perimed AB utvecklat och tillverkat LDPM- och LDPI-instrument som är baserade på en analog filterkonstruktion. De analoga komponenterna i konstruktionen är komplexa och icke-linjära med hänsyn till frekvens och de driver även med temperaturen. READ MORE
