1. 21. Of Pipes and Bends

   Författare :Jacopo Canton; Philipp Schlatter; Ramis Örlü; Dwight Barkley; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear instability; bifurcation; flow control; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : This work is concerned with the transition to turbulence of the flow in bent pipes, but it also includes an analysis of large-scale turbulent structures and their use for flow control.The flow in a toroidal pipe is selected as it represents the common asymptotic limit between spatially developing and helical pipes.

3. 22. Aspects of viscous shocks

   Författare :Malin Siklosi; GUnilla Kreiss; Smadar Karni; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; hyperbolic conservation laws; viscous shocks; modified equation; shock capturing; computer-assisted proofs; Numerisk analys; Numerical analysis; Numerisk analys;

   Sammanfattning : This thesis consists of an introduction and five papers concerning different numerical and mathematical aspects of viscous shocks. Hyperbolic conservation laws are used to model wave motion and advect- ive transport in a variety of physical applications. LÄS MER

4. 23. Evaluation of Shoulder-Complex Motion in Frontal and Oblique Impact Loadings - A Comparison between Frontal Impact Dummies and the Human Body

   Författare :Fredrik Törnvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sled tests; Cadaver; Volunteers; Kinematics; Hybrid III; Static loading; Shoulder range-of-motion; Offset frontal collision; THOR; Shoulder; Biofidelity; Oblique frontal collision; Crash test dummy; Post Mortem Human Subjects PMHS ;

   Sammanfattning : Offset and angled frontal impacts represent a crash type that is more common than full-frontal collisions. Several studies have shown that over 70% of all frontal impacts are offset or oblique. LÄS MER

5. 24. A Non-Gaussian Limit Process with Long-Range Dependence

   Författare :Raimundas Gaigalas; Ingemar Kaj; Esko Valkeila; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; long-range dependence; traffic modelling; arrival process; self-similarity; heavy tails; fractional Brownian motion; stable processes; renewal processes; independently scattered random measure; weak convergence; 60F17; 60G18; 90B18; 60K05 ; Matematisk statistik; Mathematical statistics; Matematisk statistik;

   Sammanfattning : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. LÄS MER

7. 25. Mathematical models of biological interactions

   Författare :Linnéa Gyllingberg; David J.T. Sumpter; Kolbjörn Tunström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Mathematical models are used to describe and analyse different types of biological interactions.  From self-propelled particle models capturing the collective motion of fish schools to models in mathematical neuroscience describing the interactions between neurons to individual-based models of ecological interactions.
