  1. 16. BWR In-Core Instrumentation Sensitivity to Material and Geometrical Distortions

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Mikael Nivala Fernberg; [2016]
    Nyckelord :;

    Sammanfattning : Several BWR utilities are adopting practices for determining the state of control rods based on the neutron sensitive LPRM and gamma sensitive TIP measurement systems of the nuclear reactor core. This method is in this study evaluated by quantitatively analyzing the detector sensitivity to several material and geometrical distortions in the detector vicinity, using the Los Alamos National Laboratory stochastic Monte Carlo code MCNP5 and the Westinghouse 3D core simulator POLCA7.

  3. 17. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Philipp Wittmann; [2016]
    Nyckelord :Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

    Sammanfattning :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.

  4. 18. Utformning av robotverktyg för hantering av icke-magnetiska kutsar på Borrstål 09

    M1-uppsats, Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :Mona Larsson; Andreas Wallin; [2016]
    Nyckelord :lyftverktyg; robotverktyg; materialhantering; produktutveckling; gripfunktion; icke-magnetiska ämnen;

    Sammanfattning : Sandvik Materials Technology (SMT) in Sandviken manufacture drilling rods for the mining industry. In a part of the process, cylindrical billets, so called “kuts”, are handled. Today the “kuts” are handled with a robotic controlled magnet. LÄS MER

  5. 19. Reducerat vridmotstånd i servoassisterade styrsystem

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Christoffer Nordén; [2016]
    Nyckelord :;

    Sammanfattning : In newer modern cars the steeringsystem is equipped with a servo that enhances the driver's input from the steering wheel down to the wheels. This is referred to as power-assisted steering. LÄS MER

  7. 20. Self-Balancing Robot Control System in CODESYS for Raspberry Pi : Design and Construction of a Self-Balancing Robot using PLC-programming tools

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Emil Eriksson; [2016]
    Nyckelord :Robot; Self-balancing robot; CODESYS; Raspberry Pi;

    Sammanfattning : The Department of Applied Physics and Electronics at Umeå University offers education and conducts research in the field of automation and robotics. To raise the competence in automation in the CODESYS development environment it’s proposed to build a remote controlled self-balancing robot as a testing platform which is then programmed using CODESYS for Raspberry Pi.
