  1. 1. Blind Acoustic Feedback Cancellation for an AUV

    University essay from Linköpings universitet/Reglerteknik

    Author : Hampus Frick; [2023]
    Keywords : acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Abstract : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. READ MORE

  3. 2. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Björn Walter; Stefan Piiroinen; [2021]
    Keywords : Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Abstract : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.

  4. 3. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Luke Postema; Johan Davidsson; [2019]
    Keywords : Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

    Abstract : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. READ MORE

  5. 4. Suppression of impulsive noise in wireless communication

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

    Author : qiaofeng cui; [2014]
    Keywords : GPS receiver; fastICA; BPSK; Impulsive Noise; Blind Signal Separation; Independent Component Analysis; ;

    Abstract : This report intends to verify the possibility that the FastICA algorithm could be applied to the GPS system to eliminate the impulsive noise from the receiver end. As the impulsive noise is so unpredictable in its pattern and of great energy level to swallow the signal we need, traditional signal selection methods exhibit no much use in dealing with this problem.

  6. 5. Positive reinforcement training for laboratory mice

    University essay from SLU/Dept. of Clinical Sciences

    Author : Maija Cederwall; [2014]
    Keywords : Mouse; Positive reinforcement; Training; Procedures;

    Abstract : The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal’s wellbeing, but may also influence the research results. READ MORE
