  1. 16. Feedback Control and Sensor Fusion of Vision and Force

    Författare :Tomas Olsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor based robot control; Visual tracking; visual servoing; resource optimization; Kalman filter;

    Sammanfattning : This thesis deals with feedback control using two different sensor types, force sensors and cameras. In many tasks robotics compliance is required in order to avoid damage to the workpiece. Force and vision are the most useful sensing capabilities for a robot system operating in an unknown or uncalibrated environment. LÄS MER

  3. 17. Efficient driving of CBTC ATO operated trains

    Författare :William Carvajal Carreño; Paloma Cucala García; Antonio Fernández-Cardador; Lennart Söder; Rafael Palacios Hielscher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; CBTC signalling system; ATO; Metro; Ecodriving; NSGA-II-F; pseudo-Pareto front; Tracking algorithm; Fuzzy parameters; Moving-block; Train Simulation.; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

    Sammanfattning : Energy consumption reduction is one of the priorities of metro operators, due to financial cost and environmental impact. The new signalling system Communications-Based Train Control (CBTC) is being installed in new and upgraded metro lines to increase transportation capacity. LÄS MER

  4. 18. Macroscopic modeling of fluid dynamics in large-scale circultaing fluidized beds

    Författare :David Pallarès; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel mixing; fluid dynamics; large-scale circulating fluidized bed; particle tracking;

    Sammanfattning : Satisfactory knowledge of the fluid dynamics governing the gas-solid flow in large-scaleCirculating Fluidized Bed (CFB) units is still lacking, although the CFB technology is widelyused for power (and heat) generation. Due to the complex two-phase flow in large CFB unitsfluid dynamical modeling of practical use is so far limited to a macroscopic approach andavailable models generally focus in describing one of the following key-phenomena: maingas-solid flow pattern, mixing of fuel particles and gas mixing.

  5. 19. Fetal Cardiac Function and Venous Circulation - Experiences with Velocity Vector Imaging

    Författare :Charlotte Dahlbäck; Urogynekologi och reproduktionsfarmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pregnancy; fetus; strain; speckle tracking; cardiac function; umbilical vein; venous; ductus venosus; Doppler;

    Sammanfattning : Placental dysfunction resulting in intrauterine growth restriction (IUGR) is a common complication of pregnany and severe IUGR, with ensuing fetal hypoxia is an important cause of perinatal mortality and morbidity. Doppler studies of fetal and maternal vessels are routinely used for fetal surveillance and alterations in fetal venous blood flow has been demonstrated as a late sign of fetal compromise. LÄS MER

  7. 20. World of faces, words and actions : Observations and neural linkages in early life

    Författare :Andrea Handl; Gustaf Gredebäck; Claes von Hofsten; Mikael Heimann; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Infant development; Eye-tracking; EEG; third-party interactions; crossmodal integration; gaze processing; speech processing; mu desynchronization; action perception; imitation; Psychology; Psykologi;

    Sammanfattning : From the start of their lives, infants and young children are surrounded by a tremendous amount of multimodal social information. One intriguing question in the study of early social cognition is how vital social information is detected and processed and how and when young infants begin to make sense of what they see and hear and learn to understand other people’s behavior.
