  2. 21. Quality Estimation of Approximate Models

    Author : Fredrik Tjärnström; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis discusses three different topics: model error modeling, bootstrap, and model reduction. These subjects may at first sight seem to be quite far away from each other. However, there are some connections between them, the most importantone being uncertainty estimation.Model error modeling is actually a tool for model validation. READ MORE

  4. 22. Contributions to Small Area Estimation : Using Random Effects Growth Curve Model

    Author : Innocent Ngaruye; Martin Singull; Dietrich von Rosen; Tapio Nummi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This dissertation considers Small Area Estimation with a main focus on estimation and prediction for repeated measures data. The demand of small area statistics is for both cross-sectional and repeated measures data. READ MORE

  5. 23. Joint Pose and Radio Channel Estimation

    Author : Anders Mannesson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis investigates the combination of pose and radio channel estimation. Pose is the knowledge of the position and orientation of a device whereas the radio channel describes the transmission medium between radio transmitters and receivers. READ MORE

  6. 24. To grip and not to slip : sensorimotor mechanisms in reactive control of grasp stability

    Author : Charlotte Häger Ross; Roland S. Johansson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; hand; precision grip; grasp force; friction; cutaneous mechanoreceptors; sensorimotor integration; motor control;

    Abstract : The reactive control of fingertip forces maintaining grasp stability was examined in man during a prehensile task. Blindfolded subjects used the precision grip between the tips of index finger and thumb to restrain an object that was subjected to unpredictable load forces. These were delivered tangential to the parallel grip surfaces of the object. READ MORE

  7. 25. Tactile Sensory Control of Dexterous Manipulation in Humans

    Author : Ingvars Birznieks; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. READ MORE
