  2. 6. Electromagnetic Modeling and Design of Medical Implants and Devices

    Author : Oskar Talcoth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic Resonance Imaging; Implant Safety; Lead Heating; Pacemakers; Thin-wire Approximation; Convex Relaxation; Optimal Sensor Placement; Optimal Measurements; Helix; Sensor Selection; MR Safety; Magnetic Tracking; Fisher Information Matrix;

    Abstract : This thesis covers two topics in biomedical electromagnetics: pacemaker lead heating in magnetic resonance imaging (MRI) and optimization of sensorpositions in magnetic tracking.The electromagnetic part of pacemaker lead heating during MRI is a resonant phenomenon which is complicated by, among other factors, the wide range of length scales involved in the problem.

  4. 7. Tracking Theory for Preventive Safety Systems

    Author : Lars Danielsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

    Abstract : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. READ MORE

  5. 8. On Sensor Fusion Applied to Industrial Manipulators

    Author : Patrik Axelsson; Mikael Norrlöf; Fredrik Gustafsson; Anders Robertsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the main tasks for an industrial robot is to move the end-effector in a predefined path with a specified velocity and acceleration. Different applications have different requirements of the performance. For some applications it is essential that the tracking error is extremely low, whereas other applications require a time optimal tracking. READ MORE

  6. 9. Sensor Fusion for Smartphone-based Vehicle Telematics

    Author : Johan Wahlström; Peter Händel; Erik Gudmundson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The fields of navigation and motion inference have rapidly been transformed by advances in computing, connectivity, and sensor design. As a result, unprecedented amounts of data are today being collected by cheap and small navigation sensors residing in our surroundings. READ MORE

  7. 10. Filtering and modelling for automotive safety systems

    Author : Fredrik Sandblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision-making; automotive safety; sensor data fusion; motion models; radar sensor models; filtering theory; moment estimation;

    Abstract : This thesis makes five important contributions to the development of an automotive safety system: filtering algorithms, three modelling frameworks concerning the usage of radar detections in tracking, vehicle motion, and decision-making for intervention decisions, and finally the implementation architecture.In the filtering context, we have developed a new sigma-point method for estimating the moments of a transformed Gaussian random variable.
