1. 1. Electromagnetic Modeling and Design of Medical Implants and Devices

   Författare :Oskar Talcoth; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

   Sammanfattning : Transmission of structure-borne vibrations in built-up structures, e.g. vehicles such as aircraft, automobiles and trains, is addressed. Methodologies for modeling, analysis, prediction and reduction of vibrations are developed. LÄS MER

7. 5. Experimental Design and Updating of Finite Element Models

   Författare :Magnus Andersson; Lennart Ljung; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis deals with two partly related topics: model updating and actuator/sensor placement concerning finite element (FE) models of large, flexible mechanical structures.The importance of accurate dynamical FE models of mechanical structures in, e.g., aviation/aerospace applications are steadily increasing.
