  2. 21. Optimisation of dengue diagnostic tools in order to increase the knowledge of the pathogenesis

    Author : Gunnel Lindegren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Dengue fever (DF) is the most common global viral mosquito-borne infection, with 100 million estimated cases annually in tropical and subtropical areas. The dengue viruses (genus Flavivirus, Flaviviridae) occur in 4 serotypes (DENV-1 to DENV-4). Dengue diseases range from a mild febrile disease to severe hemorrhagic fever. READ MORE

  4. 22. Molecular Quadratic Response Properties with Inclusion of Relativity

    Author : Johan Henriksson; Patrick Norman; Juha Vaara; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativistic quantum chemistry; molecular physics; clamping levels; four-component Hartree-Fock theory; Kohn-Sham density functional theory; response theory; nonlinear optics; second-harmonic generation; two-photon absorption; excited state properties; optical power limiting; Computational physics; Beräkningsfysik;

    Abstract : This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior. READ MORE

  5. 23. Studies of the fibre direction and local bending stiffness of Norway spruce timber : for application on machine strength grading

    Author : Min Hu; Marie Johansson; Mats Ekevad; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; digital image correlation; diving angle; fibre angle; grain angle; indicating property; laser scanning; modulus of elasticity; tracheid effect; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Machine strength grading is a production process in the sawmill industry used to grade sawn timber boards into different strength classes with specific characteristic values of the bending strength, modulus of elasticity (MOE) and density. These properties are called grade determining properties. READ MORE

  6. 24. Temporal Aspects of High-Intensity Laser-Matter Interactions

    Author : Johan Mauritsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Laser technology; Relativistic Self-Focusing; High-Intensity Lasers; Attosecond Pulses; Pulse Characterization; XUV; High-Order Harmonics; Ultrashort Pulses; Laserteknik; Atom- och molekylärfysik; Atomic and molecular physics; Fysicumarkivet A:2003:Mauritsson;

    Abstract : The availability of short-pulse, high-intensity lasers has opened doors to new areas in atomic and plasma physics. The short pulses (a few femtoseconds), that are available today, enable unprecedented temporal measurements, while the high peak power accessible (several terawatts) allows physicists to study the interaction between light and relativistic plasmas.

  7. 25. Computational Medical Image Analysis : With a Focus on Real-Time fMRI and Non-Parametric Statistics

    Author : Anders Eklund; Hans Knutsson; Mats Andersson; Stephen LaConte; Linköpings universitet; []
    Keywords : functional magnetic resonance imaging; brain computer interfaces; canonical correlation analysis; random permutation test; graphics processing unit;

    Abstract : Functional magnetic resonance imaging (fMRI) is a prime example of multi-disciplinary research. Without the beautiful physics of MRI, there wouldnot be any images to look at in the first place. To obtain images of goodquality, it is necessary to fully understand the concepts of the frequencydomain. READ MORE
