1. 16. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

   Författare :Johannes Töger; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

   Sammanfattning : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. LÄS MER

3. 17. Dynamical systems in cosmology and astrophysics

   Författare :Ulf Nilsson; Alan Coley; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

   Sammanfattning : General relativity is today an important branch of physics. It has, since its publication at the beginning of this century, changed from being of more mathematical than physical interest to one of the most active experimental fields in physics. LÄS MER

4. 18. Bayesian learning of structured dynamical systems

   Författare :Riccardo Sven Risuleo; Håkan Hjalmarsson; Johan Schoukens; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; bayesian learning; machine learning; Gaussian processes; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In this thesis, we propose some Bayesian approaches to the identificationof structured dynamical systems. In particular, we consider block-orientedmodels in which a complex system is built starting from simple linear andnonlinear building blocks. LÄS MER

5. 19. Consensus Algorithms in Dynamical Network Systems

   Författare :Håkan Terelius; Karl Henrik Johansson; Alexandre Proutiere; Julien M. Hendrickx; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Dynamical network systems are complex interconnected systems describing many real world problems. The current trend is to connect more and more systems together, and at the same time requiring continuous availability. To this end, it is crucial to understand the dynamic behaviors of networked systems. LÄS MER

7. 20. Mixed Effects Modeling of Deterministic and Stochastic Dynamical Systems - Methods and Applications in Drug Development

   Författare :Jacob Leander; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pharmacometrics; pharmacokinetics; mixed effects; drug development; pharmacodynamics; parameter estimation; time-to-event; mathematical modeling; dynamical systems;

   Sammanfattning : Mathematical models based on ordinary differential equations (ODEs) are commonly used for describing the evolution of a system over time. In drug development, pharmacokinetic (PK) and pharmacodynamic (PD) models are used to characterize the exposure and effect of drugs. LÄS MER
