1. 6. Nonparametric Message Passing Methods for Cooperative Localization and Tracking

   Författare :Vladimir Savic; Santiago Zazo; Spain Technical University of Madrid; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative localization; tracking; wireless sensor networks; message passing; particle filtering; belief propagation; RFID;

   Sammanfattning : The objective of this thesis is the development of cooperative localization and tracking algorithms using nonparametric message passing techniques. In contrast to the most well-known techniques, the goal is to estimate the posterior probability density function (PDF) of the position of each sensor. LÄS MER

3. 7. Bridging Single-Particle Characterisation Gaps of Optical Microscopy in the Nano-Submicron Regime

   Författare :Erik Olsén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; holography; particle shape; dynamics; Optical microscopy; particle tracking; size estimation; iSCAT; material sensitivity;

   Sammanfattning : As the practical importance of particles in the nano-submicron size regime continues to increase in both biomedical applications and industrial processes, so does the need for accurate and versatile characterisation methods. Optical scattering microscopy methods are commonly used for single-particle characterisation as they provide quick measurements at physiologically relevant conditions with detection limits reaching down to individual biomolecules.

4. 8. Recursive Bayesian Estimation : Navigation and Tracking Applications

   Författare :Niclas Bergman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target tracking; Autonomous aircraft navigation; Terrain navigation;

   Sammanfattning : Recursive estimation deals with the problem of extracting information about parameters, or states, of a dynamical system in real time, given noisy measurements of the system output. Recursive estimation plays a central role in many applications of signal processing, system identification and automatic control. LÄS MER

5. 9. Statistical methods in single particle fluorescence microscopy

   Författare :Magnus Röding; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; absolute number concentration; Brownian motion; diffusion; fluorescence microscopy; image analysis; image processing; nanoparticle characterization; particle tracking; Smoluchowski process; nanoparticle characterization;

   Sammanfattning : The aim of this thesis is stochastic modeling and statistical inference in single particle fluorescence microscopy related to the experimental observation of randomly moving particles. A central theme is the use of single particle microscopy for estimation of absolute concentration of nanoparticles performing Brownian motion. LÄS MER

7. 10. Concentration measurements in single particle microscopy

   Författare :Magnus Röding; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; fluorescence microscopy; nanoparticle characterization; number concentration; optical wide-field microscopy; single particle tracking; Smoluchowski process; diffusion;

   Sammanfattning : The topic of this thesis is the introduction of two novel methods for using single particle microscopy as a tool for absolute number concentration measurements of Brownian particles. The key idea of both methods is that in order to estimate number concentration, the size of the (three-dimensional) particle detection region has to be estimated. LÄS MER
