2. 1. Numerical Conformal Mappings for Waveguides

   Author : Anders Andersson; Börje Nilsson; Joachim Toft; Michael Benedicks; Växjö universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; waveguide; 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; Applied mathematics; Tillämpad matematik; Mathematics; Matematik;

   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

4. 2. Numerical Conformal mappings for regions Bounded by Smooth Curves

   Author : Anders Andersson; Börje Nilsson; Joachim Toft; Michael Benedicks; Växjö universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Schwarz-Christoffel mapping; rounded corners; tangent polygons; outer polygon; zipper algorithm; Schwarz-Christoffelavbildningen; rundade hörn; tangentpolygoner; yttre polygoner; zipper-algoritmer; Applied mathematics; Tillämpad matematik; Mathematics; Matematik;

   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

5. 3. The Zipper duplex method in very high-speed digital subscriber lines

   Author : Frank Sjöberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Abstract : This thesis deals with different aspects of digital subscriber lines (DSL). Over the years several DSL techniques for high-speed communication on the telephone access network have evolved that gradually have allowed higher data rates. READ MORE

6. 4. Numerical Conformal Mappings for Regions Bounded by Smooth Curves

   Author : Anders Andersson; Jönköping University; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Schwarz–Christoffel mapping; rounded corners; tangent polygons; outer polygon; zipper algorithm; Applied mathematics; Tillämpad matematik; Numerical analysis; Numerisk analys;

   Abstract : In many applications, conformal mappings are used to transform twodimensional regions into simpler ones. One such region for which conformal mappings are needed is a channel bounded by continuously differentiable curves. READ MORE
