  1. 1. Spatial positioning method development for spatial analysis of interaction in buildings

    Detta är en avhandling från Stockholm : US-AB

    Författare :Henrik Markhede; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Architecture and architectural conservation and restoration Architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Arkitektur och bebyggelsevård Arkitektur;

    Sammanfattning : In offices, knowledge sharing largely depends on everyday face-to-face interaction patterns. These interaction patterns may depend on how employees move through the office space. This thesis explores how these spatial relations influence individual choices with respect to employee movements or routes. LÄS MER

  2. 2. Sequential Monte Carlo Methods with Applications to Positioning and Tracking in Wireless Networks

    Detta är en avhandling från Department of Mathematical Statistics, Lund University

    Författare :Svetlana Bizjajeva; Lunds universitet.; Lund University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; positioning; state-space models; SMCM; particle filtering;

    Sammanfattning : This thesis is based on 5 papers exploring the filtering problem in non-linear non-Gaussian state-space models together with applications of Sequential Monte Carlo (also called particle filtering) methods to the positioning in wireless networks. The aim of the first paper is to study the performance of particle filtering techniques in mobile positioning using signal strength measurements. LÄS MER

  3. 3. Positioning the Bronze Age in Social Theory and Research Context

    Detta är en avhandling från Almqvist & Wiksell International

    Författare :Anna Gröhn; Lunds universitet.; Lund University.; [2004]
    Nyckelord :HUMANIORA; HUMANITIES; social theory; practice theory; landscape; European cultural heritage; Stora Köpinge; Archaeology; longhouses; Arkeologi; Scandinavia; Bronze Age;

    Sammanfattning : Popular Abstract in Swedish Avhandlingen undersöker den teoretiska bakgrund och den forskningskontext inom vilken tolkningar av den Nordiska bronsåldern har formats. Avhandlingens teoretiska analys betonar teorier om social praxis och fenomenologiska perspektiv. LÄS MER

  4. 4. Estimation of Nonlinear Dynamic Systems Theory and Applications

    Detta är en avhandling från Institutionen för systemteknik

    Författare :Thomas B. Schön; Linköpings universitet.; Linköpings universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Sammanfattning : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. LÄS MER

  5. 5. Gaussian Processes for Positioning Using Radio Signal Strength Measurements

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Yuxin Zhao; Linköpings universitet.; Linköpings universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian process; positioning; radio signals;

    Sammanfattning : Estimation of unknown parameters is considered as one of the major research areas in statistical signal processing. In the most recent decades, approaches in estimation theory have become more and more attractive in practical applications. LÄS MER
