Affiliation: King Abdullah University of Science and Technology Personal webpage: Dr Jan Haskovec Title: “Functional Differential Equations in Models of Collective Behavior” Abstract: The talk will give an overview of recent results for models of collective behavior governed by functional differential equations. It will focus on models of interacting agents with applications in biology (flocking, swarming),…
Academic Webpage Title: "Tools from deep learning for the dynamical systems approach to turbulence" Abstract: In the last few decades the application of ideas from dynamical systems theory has significantly improved our understanding of transitional and weakly-turbulent shear flows. The discovery of unstable periodic orbits (UPOs) embedded in turbulent attractors provides a unique insight into…
Affiliation: University of Leeds Academic webpage Title: Collective decision-making by rational agents Abstract: The decisions made by others are a valuable source of social information about the world, because they may have knowledge that we lack. This means that when one agent makes a given choice, it can induce others to do so as well.…
Affiliation: University of St Andrews Academic Webpage: Title "The space weather of other stars" Abstract: "Our understanding of stellar activity and its impact on exoplanets has been transformed by the bringing together of two complementary types of studies. Detailed spectropolarimetric studies that map the surface magnetic fields of individual stars now number more than 100…
Affiliation: University of St Andrews Personal webpage Title: Ultra Low Frequency Waves of Earth’s Magnetosphere Abstract: My research focusses on magnetohydrodynamic (MHD) waves which manifest in Earth’s magnetosphere, known as ultra low frequency (ULF) waves (frequencies ~1mHz – 1Hz). Some of the first measurements by ground magnetometers of ULF waves date back to 1859…
Affiliation: University of Exeter Academic webpage Title: Characterization of winding and entanglement in spherical and cubic volumes Abstract: It is often useful to quantify the topological complexity of magnetic fields (as well as polymer entanglements). Simulations and observations of magnetic fields often involve spherical volumes (either interior, exterior, or a spherical shell. Some simulations involve the…
Affiliation: Durham University Academic Webpage Title: Dynamical Systems Approaches and Interactive Visualisations for Pattern Formation Abstract: Natural patterns, such as those created during embryological development, can arise from enormously complex processes occurring across vast scales of space and time. A key scientific challenge is to conceptually map out these processes in terms of distinct mechanisms, and their…
Academic webpage Affiliation: University of Dundee (soon to be in St Andrews) Seminar title: A posteriori error Control and Adaptivity for problems with Finite Time Blowup Abstract: In this talk we discuss numerical strategies inspired by problems exhibiting very sharp concentrations, e.g., tumor growth and chemotaxis. More specifically, we present results on the a posteriori…
Affiliation: University of Cyprus Academic webpage Title: An exposition on hyperbolic balance laws with application to an Euler-type flocking model Abstract. Mathematical models introduced to capture the emergent behavior of self-organized systems have brought new mathematical challenges and most studies on flocking models investigate so far smooth solutions. In this talk, we will first have an overview of the theory of entropy weak solutions…
Affiliation: Coventry University Academic Webpage Title: Generating tornado-like vortices in Coriolis-centrifugal convection Abstract: Tornadoes are the most intense atmospheric vortices and have been observed on all continents of Earth (except Antarctica), and even on Mars. The most dangerous tornadoes develop within the mesocyclone of supercell thunderstorms. But what makes a mesocyclone tornadic or not remains…
Affiliation: University of Birmingham and Neuronostics Ltd Academic Webpage Title: Computational biomarkers for epilepsy from clinically non-informative EEG Abstract: In this talk, I will provide an overview of several studies where computational analysis of routine clinical recordings has led to novel set of candidate biomarkers for seizures and epilepsy. By using a dynamic network model…
Affiliation: University of Oslo, Norway Academic Webpage Title: Vortices over bathymetry Abstract: In many regions of the ocean, the flow is dominated by surface-intensified vortices with scales of 10s of kilometers. These interact with bottom topography, often non-intuitive ways. It is possible to predict the mean flow generated by such "geostrophic turbulence" using a simple variational argument. With…
