  1. 1. Get a grip on chaos : Tailored measures for complex systems on surfaces

    Author : Sascha Firle; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; complex systems; chaos; predator prey; movement models; functional response; spatial heterogeneity; topological dynamics; braid template; homoclinic bifurcations; Kvantkemi; Quantum chemistry; Kvantkemi; Quantum Chemistry; kvantkemi;

    Abstract : Complex systems are ubiquitous in physics, biology and mathematics. This thesis is concerned with describing and understanding complex systems. Some new concepts about how large systems can be viewed in a lower dimensional framework are proposed. The systems presented are examples from ecology and chemistry. READ MORE

  2. 2. Quantum Chaos and Dissipation in Finite Fermi Systems

    Author : Sergiy Radionov; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; Dissipation; Quantum Chaos; Collective motion; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

    Abstract : We address the problem of the dissipative character of collective motion in finite Fermi systems. We study this problem from the point of view of chaotic features of the fermionic degrees of freedom of the many-body Fermi systems. READ MORE

    Abstract : This thesis consists of five essays exploring the validity of some extensively used financial models with a focus on the Swedish equity and derivative markets. The essays are of both an empirical and a theoretical nature. READ MORE

  5. 5. Design and Control of Products Including Parts with Impacts

    Author : Jenny Jerrelind; KTH; []
    Keywords : Nonlinear Dynamics; Impacts; Discontinuities; Subsystems; Chaos; Irregular Behaviour; Printer Dynamics; Suspensions; Coupled Systems; Control; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Today's product development process should be rapid andcost-efficient, and should result in innovative and reliableproducts. A crucial factor is the dynamic behaviour of theproduct. READ MORE
