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. Sequential Monte Carlo Methods with Applications to Positioning and Tracking in Wireless Networks
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
Sammanfattning : The thesis investigates the theoretical background and the research context within which interpretations of the Nordic Bronze Age have been formed in Scandinavian archaeology. A theoretical analysis that emphasises theories of social practice and phenomenological perspectives is presented. LÄS MER
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
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
