2. 1. Stability and Receptivity of Three-Dimensional Boundary Layers

   Author : David Tempelmann; Dan Henningson; Stefan Hein; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional boundary layers; parabolised stability equations; adjoint PSE; crossflow instability; Fluid mechanics; Strömningsmekanik;

   Abstract : The stability and the receptivity of three-dimensional flat plate boundary layers is studied employing parabolised stability equations. These allow for computationally efficient parametric studies. Two different sets of equations are used. READ MORE

4. 2. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

   Author : Per A. Larsson; Lars Wågberg; Mikael Lindström; Lars Berglund; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE

5. 3. Stability and transition of three-dimensional boundary layers

   Author : Seyed Mohammad Hosseini; Ardeshir Hanifi; Vassilios Theofilis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional boundary layers; crossflow instability; roughness control; freestream turbulence; secondary instability;

   Abstract : A focus has been put on the stability characteristics of different flow types existing on air vehicles. Flow passing over wings and different junctions on an aircraft face numerous local features, ranging from different pressure gradients, to interacting boundary layers. READ MORE

6. 4. Conformational Stability!? : Synthesis and Conformational Studies of Unnatural Backbone Modified Peptides

   Author : Anna S. Norgren; Per I. Arvidsson; Norbert Sewald; Uppsala universitet; []
   Keywords : Organic chemistry; Conformational investigations; β-peptides; glycosylation; biomolecular recognition; cyclic β³-peptides; cyclic mixed α β²-peptides; β-peptoids; Organisk kemi;

   Abstract : The beauty of the wide functionality of proteins and peptides in Nature is determined by their ability to adopt three-dimensional structures. This thesis describes artificial molecules developed to mimic secondary structures similar to those found crucial for biological activities. READ MORE

7. 5. On stability, transition and turbulence in three-dimensional boundary-layer flows

   Author : Seyed Mohammd Hosseini; Ardeshir Hanifi; Spencer Sherwin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional bound- ary layers; crossflow instability; roughness control; freestream turbulence; sec- ondary instability; transition; turbulence;

   Abstract : A lot has changed since that day on December 17, 1903 when the Wright brothers made the first powered manned flight. Even though the concepts behind flying are unaltered, appearance of stat-of-the-art modern aircrafts has undergone a massive evolution. READ MORE
