  1. 1. Active Phase Compensation in a Fiber-Optical Mach-Zehnder Interferometer

    University essay from Linköpings universitet/Informationskodning

    Author : Joakim Argillander; [2020]
    Keywords : phase stability; interferometer; quantum key distribution; fpga; automatic control; fasstabilitet; interferometer; kvantnyckeldistribution; fpga; reglerteknik;

    Abstract : This thesis investigates the phenomena of phase stability in a fiber-optical MZI (Mach-Zehnder Interferometer). The MZI is a key building block of optical systems for use in experiments with both continuous-wave light and with single photons. READ MORE

  3. 2. Design and Implementation of a 5.8 GHz superheterodyne FM Video Receiver

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : Carl-Johan Stålberg; [2019]
    Keywords : Superheterodyne Receiver; 5.8 GHz; FM;

    Abstract : This master thesis presents the design and implementation of a super heterodyne 5.8 GHz receiver system for wireless transmission of phase alternating line (PAL) composite video signals. The system is implemented using surface and hole mounted devices on four separate printed circuit board (PCB) stages. These stages include a 5. READ MORE

  4. 3. Design and Implementation of a Glider Control System

    University essay from KTH/Optimeringslära och systemteori

    Author : Hannah Lindberg; [2015]
    Keywords : ROBEX; MOTH; glider; buoyancy; OBC; actuators; pitch; deflection; AHRS;

    Abstract : ROBEX is a unique research project combining Airbus Defence and Space’s robotics expertise with deep-sea exploration technology to discover more about the most extreme environments environments known to man. As a part of this project, a deep-sea glider called MOTH, is under development with the objective to determine whether gliders can be used as a platform for bathymetric and electromagnetic soundings of the seafloor as well as for new water column research.

  5. 4. Ultrasound induced cavitation and resonance amplification using adaptive feedback Control System

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vipul. vijigiri; Taraka Rama Krishna Pamidi; [2014]
    Keywords : Acoustic cavitation; optimization; FFT analysis; pure sine excitation; Sonotrode or ultrasonic horn; High intensity ultrasound; Sound pressure level SPL Acoustic pressure field; Feedback control; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Acoustic cavitation in fluids using high powered ultrasound has been of great interest in industries and biomedical engineering. The need for high-intensity focused ultrasound (sound with frequencies between 20 kHz to 10 MHz) and modeling of such systems has drawn great attention in engineering. READ MORE

  6. 5. Attenuation of Harmonic Distortion in Loudspeakers Using Non-linear Control

    University essay from Reglerteknik; Tekniska högskolan

    Author : Marcus Arvidsson; Daniel Karlsson; [2012]
    Keywords : EKF; exact linearisation; feed-forward; loudspeaker modelling; non-linear control; UKF;

    Abstract : The first loudspeaker was invented almost 150 years ago and even though much has changed regarding the manufacturing, the main idea is still the same. To produce clean sound, modern loudspeaker consist of expensive materials that often need advanced manufacturing equipment. READ MORE
