  2. 1. Methods for Detecting Unsolvable Planning Instances using Variable Projection

    Author : Simon Ståhlberg; Peter Jonsson; Christer Bäckström; Malte Helmert; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we study automated planning, a branch of artificialintelligence, which deals with construction of plans. A plan is typically an action sequence that achieves some specific goal. In particular, we study unsolvable planning instances, i.e. READ MORE

  4. 2. Varince component estimation in geodetic networks

    Author : Tomas Egeltoft; Lars Sjöberg; []
    Keywords : ;

    Abstract : A summary of some of the existing variance component estimators are given, namely the MINQE, the IMINQ, the general case of BQUNE (best Quardratic Unbiased Non negative Estimator), the Helmert estimators, the Förstner estimator and the Kubik estimator. A derivation of a special case of the BQUNE is made. READ MORE

  5. 3. 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

  6. 4. On Optimisation and Design of Geodetic Networks

    Author : Mohammad Amin Alizadeh Khameneh; Mehdi Eshagh; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Optimisation of a geodetic network is performed to provide its pre-set quality requirements. Today, this procedure is almost run with the aid of developed analytical approaches, where the human intervention in the process cycle is limited to defining the criteria. READ MORE
