  1. 1. Estimating area of vector polygons on spherical and ellipsoidal earth models with application in estimating regional carbon flows

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Huiting Huang; [2017]
    Keywords : spherical ellipsoidal earth model; regional carbon flows; map projection; area of a polygon; atmospheric inversions; Earth and Environmental Sciences;

    Abstract : Estimating area of polygons on the Earth’s surface is required in many fields in earth science. In the field of carbon modelling, one application of estimating polygons’ area is to estimate carbon flows for regions. READ MORE

  3. 2. Determination of a gravimetric geoid model of Kazakhstan using the KTH-method

    University essay from KTH/Geodesi och geoinformatik

    Author : Daniya Inerbayeva (Shoganbekova); [2010]
    Keywords : geoid model; least-squares modification of Stokes’ formula; the KTH-method; GPS Levelling; Kazakhstan;

    Abstract : This study work deals with the determination of the gravimetric geoid model for Kazakhstan by using the KTH-method. A number of data sets were collected for this work, such as the gravity anomalies, high-resolution Digital Elevation Model (DEM), Global Geopotential Models (GGMs) and GPS/Levelling data. READ MORE

  4. 3. Determination of a gravimetric geoid model of Greece using the method of KTH

    University essay from KTH/Geodesi och satellitpositionering

    Author : IIias Daras; [2008]
    Keywords : ;

    Abstract : The main purpose of this study is to compute a gravimetric geoid model of Greeceusing the least squares modification method developed at KTH. In regional gravimetricgeoid determination, the modified Stokes’s formula that combines local terrestrial datawith a global geopotential model is often used nowadays. READ MORE

  5. 4. The Hawking mass for ellipsoidal 2-surfaces in Minkowski and Schwarzschild spacetimes

    University essay from Matematiska institutionen

    Author : Daniel Hansevi; [2008]
    Keywords : Hawking mass; Quasi-local mass; General relativity; Ellipsoidal surface;

    Abstract : In general relativity, the nature of mass is non-local. However, an appropriate def-inition of mass at a quasi-local level could give a more detailed characterization ofthe gravitational field around massive bodies. Several attempts have been made tofind such a definition. One of the candidates is the Hawking mass. READ MORE
