  2. 1. Shape optimization in compressible inviscid flow

    Author : Oskar Enoksson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes methods for aerodynamic optimization, including a new derivation of an adjoint method for efficient computation and regularization of the gradient. Also, a general method using different surface parameterizations is presented. READ MORE

  4. 2. Multiplet structure studies of some manganese compounds

    Author : Olli Launila; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A number of manganese compounds have been studied with different spectroscopic methods. The four electronic transitions (fc^n^-a5^*, c5£+-a5£+, d5ïïi-a5S+ and e5Z+-a5£+) in the quintet manifold of MnH have been analyzed. Also, the three first mentioned transitions have been analyzed in the isotopic molecule MnD. READ MORE

  5. 3. Experimental Studies of the Neutron Deficient Atomic Nuclei 88Ru and 87Tc, and the Diagonalization of the General Pairing Hamiltonian

    Author : Xiaoyu Liu; Bo Cederwall; Chong Qi; Jelena Vesic; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

    Abstract : This doctoral thesis consists of two parts: the experimental study of the neutron-deficient atomic nuclei 88Ru and 87Tc, and the computational study on the diagonalization of general pairing Hamiltonian. In the first part, which constitutes the main content of the thesis, the low-lying excited states in the N = Z nucleus 88Ru and N = Z + 1 nucleus 87Tc were studied via fusion-evaporation reactions induced by 115 MeV 36 Ar ions bombarding6 mg/cm 2 thick metallic 54 Fe target foils at the Grand Accélérateur Nationald’Ions Lourds (GANIL), Caen, France.

  6. 4. High-Performance I/O Programming Models for Exascale Computing

    Author : Sergio Rivas-Gomez; Stefano Markidis; Erwin Laure; Martin Schulz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The success of the exascale supercomputer is largely dependent on novel breakthroughs that overcome the increasing demands for high-performance I/O on HPC. Scientists are aggressively taking advantage of the available compute power of petascale supercomputers to run larger scale and higher-fidelity simulations. READ MORE

  7. 5. 3-D numerical modeling of flow and sediment transport in rivers

    Author : Muluneh Admass; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; River model; ECOMSED model; River Klarälven; Bed load transport model; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The fully integrated 3-D, time dependant, hydrodynamic and sediment transport numerical model ECOMSED was used to simulate flow and sediment transport in rivers. ECOMSED was originally developed for large water bodies such as lakes and oceans and solves the primitive equations of RANS along with a second order turbulence model in an orthogonal curvilinear σ- coordinate system.
