  1. 41. Learning based Word Search and Visualisation for Historical Manuscript Images

    Författare :Tomas Wilkinson; Anders Brun; Josep Lladós; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Word Spotting; Convolutional Neural Networks; Deep Learning; Region Proposals; Historical Manuscripts; Computer Vision; Image Analysis; Visualisation; Document Analysis; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Today, work with historical manuscripts is nearly exclusively done manually, by researchers in the humanities as well as laypeople mapping out their personal genealogy. This is a highly time consuming endeavour as it is not uncommon to spend months with the same volume of a few hundred pages. LÄS MER

  3. 42. Characterisation of inputs and outputs of striatal medium spiny neurons in health and disease

    Författare :Marko Filipović; Jeanette Hellgren Kotaleski; Arvind Kumar; Gilad Silberberg; Ad Aertsen; Andrew Sharott; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; basal ganglia; striatum; medium spiny neurons; subthalamic nucleus; globus pallidus; Parkinson s disease; in vivo; oscillations; spectral analysis; response variability; networks; simulations; modelling; Numerical Analysis; Numerisk analys; Computer Science; Datalogi; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Striatal medium spiny neurons (MSNs) play a crucial role in various motor and cognitive functions. They are separated into those belonging to the direct pathway (dMSNs) and the indirect pathway (iMSNs) of the basal ganglia, depending on whether they express D1 or D2 type dopamine receptors, respectively.

  4. 43. The Kirunavaara hangingwall : a geophysical and petrophysical analysis

    Författare :Mai-Britt Mose Jensen; Håkan Mattsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : Underground mining of the Kirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly even predict this deformation, a good understanding of the elastic and mechanical properties of the rocks in the hangingwall is necessary. LÄS MER

  5. 44. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems

    Författare :Fredrik Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry PIV ; single-phase; Laser Doppler Anemometry LDA ; mixing; liquid-Liquid; immiscible; stirred tank; Rushton turbine; Computational Fluid Dynamics CFD ; macro-instability; frequency analysis; refraction index matched;

    Sammanfattning : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. LÄS MER

  7. 45. Design flood estimation under uncertainty

    Författare :Kenechukwu Okoli; Giuliano Di Baldassarre; András Bárdossy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dimensionerande flöden; osäkerheter; avrinningsmodellering; frekvens analys.; Dimensionerande flöden; osäkerheter; avrinningsmodellering; frekvens analys.; Design flood; uncertainty; rainfall-runoff; frequency analysis.; Hydrology; Hydrologi;

    Sammanfattning : Att bestämma dimensionerande flöden, d.v.s. sannolikheten för att vat-tenföringen i ett vattendrag överskrider ett givet värde, är ett allmänt hydrologiskt problem som exempelvis används för att utvärdera över-svämningsrisker i vattendrag samt för att dimensionera hydrauliska kon-struktioner.
