  1. 6. On Robotic Work-Space Sensing and Control

    Författare :Magnus Linderoth; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; computer vision; color constancy; motion blur; filter initialization; visual tracking; on-line trajectory generation; ball-catching robot; force control; robotic assembly; force estimation; perception-action capabilities.;

    Sammanfattning : Industrial robots are fast and accurate when working with known objects at precise locations in well-structured manufacturing environments, as done in the classical automation setting. In one sense, limited use of sensors leaves robots blind and numb, unaware of what is happening in their surroundings. LÄS MER

  2. 7. Robotic Work-Space Sensing and Control

    Författare :Magnus Linderoth; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assembly; force control; on-line trajectory generation; filter initialization; visual tracking; Robotics; computer vision; cooperating robots;

    Sammanfattning : Industrial robots are traditionally programmed using only the internal joint position sensors, in a sense leaving the robot blind and numb. Using external sensors, such as cameras and force sensors, allows the robot to detect the existence and position of objects in an unstructured environment, and to handle contact situations not possible using only position control.

  3. 8. On the choice of initial state in numerical weather prediction models

    Författare :Lennart Thaning; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with the problem of initializing numerical weather prediction models based on the primitive equation system. The normal mode approach is used i.e. the variables are projected on the eigensolutions of the linearized model equations. LÄS MER

  4. 9. Investigations of problems related to the choice of the initial state for numerical weather prediction models

    Författare :Stefan Gollvik; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In numerical prediction models, where the wind and mass fields are described as free variables (so called primitive equation models), the initial state has to be carefully chosen, to avoid spurious oscillations in the forecast. This thesis deals with this initialization problem. LÄS MER

  5. 10. Characterizing Piecewise Linear Neural Networks

    Författare :Anton Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; automotive applications.; neural network; machine learning; piecewise linear;

    Sammanfattning : Neural networks utilizing piecewise linear transformations between layers have in many regards become the default network type to use across a wide range of applications. Their superior training dynamics and generalization performance irrespective of the nature of the problem has resulted in these networks achieving state of the art results on a diverse set of tasks.
