  1. 16. Design of Low-Order Controllers using Optimization Techniques

    Författare :Martin Hast; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In many applications, especially in the process industry, low-level controllers are the workhorses of the automated production lines. The aim of this study has been to provide simple tuning procedures, either optimization-based methods or tuning rules, for design of low-order controllers. The first part of this thesis deals with PID tuning. LÄS MER

  3. 17. Positioning and Tracking in Asynchronous Wireless Sensor Networks

    Författare :Mats Rydström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with the problem of locating mobile nodes in anasynchronous wireless communication network, i.e., a wireless network of mobileterminals where some or all nodes do not have access to a global time reference. LÄS MER

  4. 18. Blind Signal Separation by Second Order Statistics

    Författare :Henrik Sahlin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The problem of separating uncorrelated signals from equally many observed mixtures is considered in this thesis. Each observed signal is modeled as a sum of original signals filtered through unknown linear filters. LÄS MER

    Sammanfattning : In today’s modern society, we are surrounded by a multitude of digital devices.The number of available digital devices is set to grow even more. As the trendcontinues, product life-cycle is a major issue in mass production of these devices. LÄS MER

  7. 20. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration

    Författare :Kenneth Nilsson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fingerprint recognition; symmetry filters; orientation field; multiscale filtering; singular points; orientation radiograms; registration; multiexpert; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. LÄS MER
