1. 36. Assessing Soil Functions for Sustainable Remediation of Contaminated Sites

   Författare :Yevheniya Volchko; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soil ecosystem services; Contaminated sites soil; minimum data set; remediation; sustainability assessment; soil quality indicators; soil functions;

   Sammanfattning : Soil contamination is a worldwide problem. Soil remediation is often carried out to reduce the risks posed by contaminants in the soil to human health and environment. Contaminant concentration is typically the only soil quality aspect maintained in remediation projects. LÄS MER

3. 37. Distance Functions and Their Use in Adaptive Mathematical Morphology

   Författare :Vladimir Ćurić; Gunilla Borgefors; Cris L. Luengo Hendriks; Hugues Talbot; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Distance functions; Mathematical morphology; Adaptive mathematical morphology; Image regularization; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : One of the main problems in image analysis is a comparison of different shapes in images. It is often desirable to determine the extent to which one shape differs from another. This is usually a difficult task because shapes vary in size, length, contrast, texture, orientation, etc. Shapes can be described using sets of points, crisp of fuzzy. LÄS MER

4. 38. Quantum many-body systems exactly solved by special functions

   Författare :Martin Hallnäs; Edwin Langmann; Pavel Winternitz; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum many-body systems; integrable systems; special functions; Mathematical physics; Matematisk fysik;

   Sammanfattning : This thesis concerns two types of quantum many-body systems in one dimension exactly solved by special functions: firstly, systems with interactions localised at points and solved by the (coordinate) Bethe ansatz; secondly, systems of Calogero-Sutherland type, as well as certain recently introduced deformations thereof, with eigenfunctions given by natural many-variable generalisations of classical (orthogonal) polynomials. The thesis is divided into two parts. LÄS MER

5. 39. Nanostructured Semiconductor Materials for Light Manipulation Functions

   Författare :Dennis Visser; Srinivasan Anand; Alvaro Blanco; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semiconductor materials; c-Si; a-Si; GaInP; TiO2; ZnO; nanostructuring; light manipulation functions; top-down fabrication; embossing; FDTD simulations; nanowires; nanopillars; nanodisks; microcones; optical response; reflectance; transmittance; absorbance; spectrophotometry; photoluminescence; Mie resonators; mode coupling; broadband anti-reflection; light extraction enhancement; optical sensing; optical color filters; color conversion; Optik och fotonik; Optics and Photonics;

   Sammanfattning : Structuring of semiconductor materials is utilized in many optoelectronic devices, e.g, in order to make them more efficient, cost-effective, and/or to obtain specific wavelength-engineered responses. Semiconductor materials are widely used in optoelectronic devices due to their favorable optical and electric properties. LÄS MER

7. 40. Functions of Generalized Bounded Variation

   Författare :Martin Lind; Viktor Kolyada; Peter Oswald; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bounded p-variation; generalized bounded variation; modulus of continuity; function spaces; embeddings; Matematik; Mathematics;

   Sammanfattning : This thesis is devoted to the study of different generalizations of the classical conception of a function of bounded variation.First, we study the functions of bounded p-variation introduced by Wiener in 1924. We obtain estimates of the total p-variation (1.. LÄS MER
