  1. 1. Numerical Conformal mappings for regions Bounded by Smooth Curves

    University dissertation from Växjö : Matematiska och systemtekniska institutionen

    Author : Anders Andersson; Högskolan i Jönköping.; Växjö universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys; Schwarz–Christoffel mapping; rounded corners; tangent polygons; outer polygon; zipper algorithm; Mathematics; Matematik; Schwarz-Christoffel mapping; Schwarz-Christoffelavbildningen; rundade hörn; tangentpolygoner; yttre polygoner; zipper-algoritmer;

    Abstract : Inom många tillämpningar används konforma avbildningar för att transformera tvådimensionella områden till områden med enklare utseende. Ett exempel på ett sådant område är en kanal av varierande tjocklek begränsad av en kontinuerligt deriverbar kurva. READ MORE

  2. 2. Numerical Conformal Mappings for Waveguides

    University dissertation from Växjö : Matematiska och systemtekniska institutionen

    Author : Anders Andersson; Högskolan i Jönköping.; Växjö universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik; waveguides; building block method; numerical conformal mappings; Schwarz–Christoffel mapping; rounded corners method; approximate curve factors; outer polygon method; boundary curvature; zipper method; geodesic algorithm; acoustic wave scattering; electro-magnetic wave scattering; Mathematics; Matematik; waveguide;

    Abstract : Acoustic or electro-magnetic scattering in a waveguide with varying direction and cross-section can be re-formulated as a two-dimensional scattering problem, provided that the variations take place in only one dimension at a time. By using the so-called Building Block Method, it is possible to construct the scattering properties of a combination of scatterers when the properties of each scatterer are known. READ MORE

  3. 3. Radiological Studies on Hippocampal Development Morphological Variants and their Relationship to Epilepsy

    University dissertation from Uppsala : Institutionen för onkologi, radiologi och klinisk immunologi, Enheten för radiologi

    Author : Dragan Bajic; Uppsala universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Brain development; Hippocampus; Epilepsy; MEDICINE Physiology and pharmacology Radiological research Radiology; MEDICIN Fysiologi och farmakologi Radiologisk forskning Radiologi; Radiology; Radiologi;

    Abstract : During fetal development, the hippocampal structures are folded forming the hippocampal sulcus which penetrates into the temporal lobe and then the entity rotates.  During this process, the hippocampal sulcus will be closed and the inverted hippocampus takes a rounded form.

  4. 4. Aspects in mammographic screening : Detection, prediction, recurrence and prognosis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mercidyl Gelig Thurfjell; Uppsala universitet.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Breast neoplasms; recurrence; Onkologi; MEDICINE Surgery Oncology; MEDICIN Kirurgi Onkologi; diagnostisk radiologi; Diagnostic Radiology;

    Abstract : Screening mammograms comprising of 32 first round, 10 interval and 32 second round detected cancers and 46 normal were examined by an expert screener, a screening radiologist, a clinical radiologist and a computer-assisted diagnosis (CAD) system. The expert screener, screening radiologist, clinical radiologist and the CAD detected 44, 41, 34 and 37 cancers, respectively, while their respective specificities were 80%, 83%, 100% and 22%.

  5. 5. Effect of Physical Weathering on Mechanical Properties of Tailings

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Juan Rodriguez; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : The mining activity produces minerals to supply to the modern society with commodities. During the ore refining process large amounts of tailings are generated as waste. Tailings are the result of crushing and wet milling, typically in the size range of sand to silt and angular in shape. READ MORE
