  2. 6. Position Estimation and Tracking in Colloidal Particle Microscopy

    Author : Mats Kvarnström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; censored regression; colloidal chemistry; depth estimation; diffusion coefficient; nonparametric function estimation; position estimation; rotational symmetry; tracking; template matching; video microscopy; rotational symmetry;

    Abstract : This thesis presents methods for estimating the locations (including depth) of spherical colloidal particles in images recorded in video microscopy. Understanding the behavior of colloidal interactions and diffusion is of crucial importance in a vast number of areas. READ MORE

  4. 7. Particle Coating in a Wurster Type Bed

    Author : Stina Karlsson; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Particle; Tracking technique; Spouted bed; Fluidisation; Multiphase flow; CFD; Trajectory; Coating; Wurster;

    Abstract : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. READ MORE

  5. 8. Optical characterisation of subwavelength dielectric particles using particle tracking beyond the Stokes-Einstein relation

    Author : Erik Olsén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; off-axis holography; Optical microscopy; size determination; particle tracking; partial slip; lipid vesicles; particle dynamics;

    Abstract : As the importance of nanoparticles continues to increase in both biology and industrial processes, so does the need for accurate and versatile characterisation methods. However, most light-based methods to quantify size and refractive index of individual particles are either limited to snapshot observations, particles larger than the wavelength of light, non-dynamic particle properties, or assuming the hydrodynamic boundary conditions without experimental evaluation.

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

    Author : Vladimir Savic; Santiago Zazo; Spain Technical University of Madrid; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 10. Tracking Chambers with Two-Dimensional Readout used for Extraction of Particle Production Ratios in High Multiplicity Pb+Pb Collisions at 158 A GeV

    Author : Tomas Svensson; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; position resolution; wire chamber pixel readout; pad readout; tracking; multi-step avalanche chamber; Fysik; Physics; particle ratios;

    Abstract : Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. READ MORE
