  2. 1. Multi-oriented Symplectic Geometry and the Extension of Path Intersection Indices

    Author : Serge de Gosson de Varennes; Andrei Khrennikov; Ernst Binz; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Symplectic geometry; algebraic topology; mathematical physics; Maslov index; Conley-Zehnder index; Leray index path intersection indices.; MATHEMATICS; MATEMATIK;

    Abstract : Symplectic geometry can be traced back to Lagrange and his work on celestial mechanics and has since then been a very active field in mathematics, partly because of the applications it offers but also because of the beauty of the objects it deals with.I this thesis we begin by the simplest fact of symplectic geometry.

  4. 2. On the inception of leakage : Effect of hydrostatic pressure on the sealing interface

    Author : De Huang; Andreas Almqvist; Roland Larsson; Xiang Yan; Alessandro Ruggiero; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static seal; contact mechanics; hydrostatic; critical pressure; leakage; Maskinelement; Machine Elements;

    Abstract : As the move towards sustainability continues,  attention needs to be paid to the development of new machinery with high performance and low environmental impact. It places increasing demands on low/zero-emission sealing with a long lifetime. READ MORE

  5. 3. Elucidating regulatory elements : studies in chronic lymphocytic leukemia and multiple myeloma

    Author : Ayla De Paepe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : With next generation sequencing taking center stage in genetic and epigenetic research, its applications and challenges are many. This work revolves around the application of bioinformatics in different contexts: basic research in the understanding of diseases (biology), the effect of treatment on the target cells (clinics) and the assessment of a new wet-lab method (lab).

  6. 4. Synthetic lubricants and polymer composites for large full film journal bearings

    Author : Gregory F Simmons; Patrick De Baets; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The rapid build-up of variable renewable power sources such as wind and solar are leading to increased instability in the electrical grid. Many methods of controlling this instability have been proposed but existing hydroelectric power plants in many cases already been enlisted to fill the regulating power needs of industry and the population.

  7. 5. Investigation of lithium and fluorine content in geological materials using Nuclear Reaction Analysis (NRA)

    Author : Nathaly de La Rosa; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nuclear reaction analysis NRA ; Geological material; Elemental composition analysis; Ion Beam Analysis IBA ;

    Abstract : This work focuses on the optimization of the Nuclear Reaction Analysis (NRA) technique to determine the content of lithium and fluorine in geological materials. Measuring low concentration of these isotopes is of great relevance in many fields such as geological, astrophysical, biological and material sciences. READ MORE
