  1. 36. Lip-motion biometrics for audio-visual identity recognition

    Författare :Maycel Isaac Faraj; Massimo Tistarelli; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biometrics; Lip motion; Audio-visual signals; Speech recognition; Speaker recognition; Digit recognition; Image analysis; Bildanalys;

    Sammanfattning : Biometric recognition systems have been established as powerful security tools to prevent unknown users from entering high risk systems and areas. They are increasingly being utilized in surveillance and access management (city centers, banks, etc.) by using individuals' physical or biological characteristics. LÄS MER

  3. 37. Computer Vision: From Motion Capture to Tabletop Interaction

    Författare :Tommaso Piazza; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical tracking; tabletop; motion capture; cscw; missing maker; multi-touch;

    Sammanfattning : This thesis presents the work done by the candidate in the domain of Human-Computer Interaction. In particular, the candidate has investigated how techniques in Computer Vision can be used to enable new forms of interaction. The work investigates areas such as motion capture and multi-user, multi-touch interaction for tabletop systems. LÄS MER

  4. 38. Relaxation and Resonance in Brownian Motion-Coupled Resonators

    Författare :Christin Rhen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonequilibrium dynamics; nonlinear dynamics; resonance; nanomechanics; relaxation; superconducting circuits.; resonator; dispersive coupling; noise; Brownian motion;

    Sammanfattning : In physics, there exists a number of paradigm systems – exactly solvable models that can represent a wide variety of physical realizations. My research is concerned with two of these paradigm systems: the harmonic oscillator and Brownian motion. LÄS MER

  5. 39. Human–Robot Interaction Based on Motion and Force Control

    Författare :Martin Karlsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Machine Learning; Force Control; Motion Control;

    Sammanfattning : Industrial robots typically require detailed programming and carefully configured work cells to perform well. The large engineering effort implicates high cost and long preparation time, and this is the major obstruction when mediating tasks to robots. The research in this thesis therefore aims to make robot programming faster and more accessible. LÄS MER

  7. 40. Prediction of Strong Ground Motion and Hazard Uncertainties

    Författare :Behrooz Tavakoli; Ota Kulhanek; Dieter Mayer-Rosa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Disaggregation; Ground motion; Monte Carlo simulation; Seismic hazard; Geofysik; Geophysics; Geofysik; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : The purpose of this thesis is to provide a detailed description of recent methods and scientific basis for characterizing earthquake sources within a certain region with distinct tectonic environments. The focus will be on those characteristics that are most significant to the ground-shaking hazard and on how we can incorporate our current knowledge into hazard analyses for engineering design purposes.
