  1. 1. Track circuits’ robustness : Modeling, measurement and simulation

    Författare :Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER

  3. 2. Surviving under water : Physiological limitations and technical possibilities

    Författare :Mårten Silvanius; Oskar Frånberg; Rachel Lance; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; diving apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring; decompression; hyperbaric oxygen therapy; Systemteknik; Systems Engineering;

    Sammanfattning : The survival of humans in underwater environments necessitates a comprehensive understanding of both physiological factors and advanced technologies. Diving with self-contained underwater breathing apparatuses (SCUBA) remains one of the most common ways for human underwater activities. LÄS MER

  4. 3. Towards an integrated framework for modeling, control, and validation of production systems

    Författare :Martin Dahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; virtual commissioning; automation engineering; virtual reality; Virtual preparation;

    Sammanfattning : To prepare a production system before installation includes a multitude of computer assisted tasks. Virtual preparation, including many simulation supported activities, has made great strides during the last decade. Industrial robots are routinely programmed offline in simulation environments.

  5. 4. Hydrobatics: Efficient and Agile Underwater Robots

    Författare :Sriharsha Bhat; Ivan Stenius; Dimos V. Dimarogonas; Alexander Phillips; KTH; []
    Nyckelord :Autonomous Underwater Vehicles; Modeling; Simulation; Control; Field Testing; Cyber-physical Systems.; Autonoma Undervattensfarkoster AUV ; Modellering; Simulering; Reglerteknik; Fältprovning; Cyber-fysikaliska System CPS .; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Hydrobatic capabilities in autonomous underwater vehicles (AUVs) can enable increased maneuverability without a sacrifice in efficiency and speed. This means innovative robot designs and new use case scenarios are possible. LÄS MER

  7. 5. Development of Microcomponents for Attitude and Communication Systems on Small Vehicles in Space and Extreme Environments

    Författare :Kristoffer Palmer; Greger Thornell; Hugo Nguyen; Henrik Kratz; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Administrative Law; Förvaltningsrätt;

    Sammanfattning : In this thesis, components intended for vehicles in space and other extreme environments have been realized using microsystems technology to facilitate miniaturized, yet high-performing systems beneficial for small spacecraft and other vehicles with limited size and power.Cold gas thrusters commonly used on spacecraft basically accelerate a gaseous propellant stored under high pressure.
