  2. 1. Regional Geoid Determination Methods for the Era of Satellite Gravimetry : Numerical Investigations Using Synthetic Earth Gravity Models

    Author : Jonas Ågren; Lars E. Sjöberg; Zdenek Martince; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; geoid determination; GOCE; synthetic earth gravity models; kernel modification; downward continuation; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : It is the purpose of this thesis to investigate different regional geoid determination methods with respect to their feasibility for use with a future GOCE satellite-only Earth Gravity Model (EGM). This includes investigations of various techniques, which involve different approximations, as well as the expected accuracy. READ MORE

  4. 2. On the Logic of Theory Change : Extending the AGM Model

    Author : Eduardo Fermé; John Cantwell; David Makinson; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Logic of Theory Change. AGM model. Belief Bases; Iterated Models; Multiple belief change; AGM and defeasible Logic; Logic; Logik;

    Abstract : This thesis consists in six articles and a comprehensive summary. • The pourpose of the summary is to introduce the AGM theory of belief change and to exemplify the diversity and significance of the research that has been inspired by the AGM article in the last 25 years. READ MORE

  5. 3. TCP in Wireless Networks: Challenges, Optimizations and Evaluations

    Author : Stefan Alfredsson; Anna Brunström; Lars-Åke Larzon; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless networks; TCP IP; TCP-L; Network emulation; Computer science; Datavetenskap; Computer Science; Datavetenskap;

    Abstract : This thesis presents research on transport layer behavior in wireless networks. As the Internet is expanding its reach to include mobile devices, it has become apparent that some of the original design assumptions for the dominant transport protocol, TCP, are approaching their limits.

  6. 4. 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

  7. 5. Traffic and Road Sign Recognition

    Author : Hasan Fleyeh; Högskolan Dalarna; []
    Keywords : Traffic signs; color segmentation; recognition;

    Abstract : This thesis presents a system to recognise and classify road and traffic signs for the purpose of developing an inventory of them which could assist the highway engineers’ tasks of updating and maintaining them. It uses images taken by a camera from a moving vehicle. READ MORE
