  1. 16. Developing a Fluid Flow Model for Mobile Video Transmission in the Presence of Play-Out Hysteresis

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : Atefeh Dehghannayyeri; [2016]
    Keywords : fluid flow models; video transmission; play-out hysteresis; freeze; buffering;

    Abstract : This work focuses on improving video transmission quality over a mobile link. More specifically, the impact of buffering and link outages on the freeze probability of transmitted videos is studied. It introduces a new fluid flow model that provides an approximation of the freeze probability in the presence of play-out hysteresis. READ MORE

  3. 17. Modelling of Mechanical Flexibilities in Robotic Manipulators and Evaluation of Their Impact on Motion Performance

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Patrik Levin; Daniel Mofors; [2016]
    Keywords : ;

    Abstract : In order to achieve the best robot performance, the exibilities in the mechanical structures of a robot manipulator needs to be modelled and compensated for, when designing a controller. By examining how each flexible component contribute to the overall dynamic performance, the robot's mechanical design can be altered to optimised performance and minimise cost. READ MORE

  4. 18. Open Loop Control of Piezoelectric Cantilever Speaker

    University essay from Linköpings universitet/Reglerteknik

    Author : John Wilhelms; Marcus Trulsson; [2015]
    Keywords : Piezoelectric speaker; Bimorph Cantilever Actuator; Physical beam modeling;

    Abstract : Actuating a cantilever piezoelectric element over a frequency spectrum, the movement will show resonances and hysteresis behavior not present in the input signal. Excursion modeling and open loop control of a cantilever piezoelectric bimorph actuator was studied in this thesis, with the aim to enhance the actuator's movement to more accurately render audible input.

  5. 19. Analysis oft yre wear using the expanded brush tyre model

    University essay from KTH/Fordonsdynamik

    Author : Mahdi Mohammadi; Ray Ngeno; [2015]
    Keywords : ;

    Abstract : Approximately 60 000 tonnes of tyres are produced annually in Sweden to meet thedemand in the market. It is believed that 10 000 tonnes of rubber particles contaminatesthe Swedish roads every year. Some of the elements in the emitted particles cannegatively impact the environment. READ MORE

  6. 20. Simulation of how pressure influences the reactive sputtering process

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Erik Strandberg; [2015]
    Keywords : thin film; sputtering; reactive sputtering; simulation; pressure; hysteresis;

    Abstract : Sputtering is a physical vapor deposition (PVD) process used to create thin films, i.e very thin layers of material. To form compounds, such as oxides and nitrides, it may be beneficial to add a reactive gas to the process which is known as reactive sputtering. READ MORE
