2. 1. A Multi Sensor System for a Human Activities Space : Aspects of Planning and Quality Measurement

   Author : Jiandan Chen; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D Reconstruction; Iso-disparity Surfaces; Depth Reconstruction Uncertainty; Uncertainty Analysis; Dither; Sensor Placement; Multi Stereo View; Image Quality; Human Factor;

   Abstract : In our aging society, the design and implementation of a high-performance autonomous distributed vision information system for autonomous physical services become ever more important. In line with this development, the proposed Intelligent Vision Agent System, IVAS, is able to automatically detect and identify a target for a specific task by surveying a human activities space.

4. 2. 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.

5. 3. Identification and Synthesis of Components for Vibration Transfer Path Analysis

   Author : Per Sjövall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor placement; Indirect sensing; Vibration control; System identification; Experimental methods; Substructuring; Kalman filter; Transfer path analysis; State-space models;

   Abstract : 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. READ MORE

6. 4. Preliminaries for probabilistic railway sleeper design

   Author : Johanna Lilja; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor placement; factorial design; Railway sleeper; ballast; load variation; stochastic parameters; correlation length;

   Abstract : Two investigations are presented, which can be seen ascontributions to the aim of introducing a probabilistic designstrategy of railway sleepers in the future. When usingprobabilistic design the statistics of all relevant parametersconsidered as stochastic must be known. READ MORE

7. 5. Wireless Sensor Networks in Smart Cities : The Monitoring of Water Distribution Networks Case

   Author : Du Rong; Carlo Fischione; Ming Xiao; Iordanis Koutsopoulos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Programming; Nonconvex Optimization; Network Lifetime; Dynamic; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The development of wireless sensor networks (WSNs) is making it possible to monitor our cities. Due to the small size of the sensor nodes, and their capabilities of transmitting data remotely, they can be deployed at locations that are not easy or impossible to access, such as the pipelines of water distribution networks (WDNs), which plays an important role in protecting environment and securing public health.
