  1. 6. Detection of Human Emotion from Noise Speech

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Sai Chandra Sekhar Reddy Nallamilli; Nihanth Kandi; [2020]
    Keywords : Neural Network; Activation Function; Fast Fourier Transform; Karhunen-Loeve Transform; speech enhancement; filtering; Wavelet Transform; Speech preprocessing; signal to noise ratio; shallow neural network;

    Abstract : Detection of a human emotion from human speech is always a challenging task. Factors like intonation, pitch, and loudness of signal vary from different human voice. So, it's important to know the exact pitch, intonation and loudness of a speech for making it a challenging task for detection. READ MORE

  4. 8. Unbiased pitch detection and phase estimation in entomological lidar

    University essay from Lunds universitet/Matematisk statistik

    Author : Johan Fogelmark; [2019]
    Keywords : Entomological lidar; wing beat frequency estimation; phas; Mathematics and Statistics;

    Abstract : Good insect monitoring is important for both disease vector control and e?cient usage of pesticides in farming. Entomological lidar has been proven useful for detecting and monitoring insects. For every insect that transit the laser beam a backscatter signal containing species-specific information is obtained.

  6. 10. Detecting External Forces on an Autonomous Lawnmowing Robot with Inertial, Wheel Speed and Wheel Motor Current Measurements

    University essay from Linköpings universitet/Reglerteknik

    Author : Gustav Norin; [2017]
    Keywords : ;

    Abstract : An autonomous lawn mowing robot moves around randomly within an area enclosed by a magnetic wire and makes decision based on sensor information. To ensure human and animal safety it is essential that the robotic lawn mower can detect and stop if, for instance, it is being lifted by a human. READ MORE
