    Abstract : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. READ MORE

  3. 3. Numerical solution of the Fokker–Planck approximation of the chemical master equation

    University dissertation from Uppsala University

    Author : Paul Sjöberg; Per Lötstedt; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Abstract : The chemical master equation (CME) describes the probability for the discrete molecular copy numbers that define the state of a chemical system. Each molecular species in the chemical model adds a dimension to the state space. READ MORE

  4. 4. Developing Computational Tools for Modern Aeroacoustic Research

    University dissertation from VOK LTH box 118 22100 Lund

    Author : Mirela Caraeni; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; unstructured mesh; termoacoustic; acoustic; cfd; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : The thesis presents the author s research on numerical methods for Com-putational Aeroacoustics and the development of computational tools with direct applicability in industry. The designers in the gas-turbine industry, require accurate methods for predicting the onset and the frequencies of dangerous (pressure) oscillations, like the ones which typically occur in Lean Premixed Pre-vaporized (LPP) combustors.

  5. 5. A Neural Network Technique for Retrieving Atmospheric Species from Microwave Limb Sounders

    University dissertation from VOK LTH box 118 22100 Lund

    Author : Carlos Jimenez Sanchez; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Atmospheric radiometry requires solving an inversion problem due to the indirect nature of the measurements. Traditional iterative methods for non-linear inversions are computationally intensive and faster algorithms are desirable. READ MORE
