PICS Colloquium (Virtual): “Modelling active matter on large length and time scales” with Robert Jack
Abstract: Active matter consists of particles that do work on their environment, for example by propelling themselves through a solvent. Fluids made from many interacting self-propelled particles have become popular […]
PICS Colloquium: “Learning parsimonious models by covariance balancing” with Clarence Rowley
Abstract: Data-driven reduced-order models often struggle with high-dimensional nonlinear systems sensitive to low-variance coordinates, which are typically truncated. To address this, we use ideas from balanced truncation and active subspaces […]
PICS Colloquium: “Stochastic Reaction-Diffusion-Dynamics Modeling of whole systems: application to fibrin clot contraction and fibrin clot rupture” with Valeri Barsegov
Abstract: Stochastic Reaction-Diffusion-Dynamics Model (SRDDM) for particle-based simulations of mechanochemical processes for thermodynamically large systems with high spatial and temporal resolution will be presented. The SRDDM couples the spatially inhomogeneous […]
MEAM Seminar: “Modeling and Analysis of Wall-bounded Turbulent Flows”
Most fluid flows at human scales and at moderate speeds (> 1 m/s) reach Reynolds numbers of at least 10⁴ or higher, causing even tiny disturbances to amplify and drive […]
PICS Colloquium: Macroscopic stochastic thermodynamics with Massimiliano Esposito [VIRTUAL]
This speaker event is virtual, but will be screened in PICS 534 with refreshments. Equilibrium thermodynamics emerges from equilibrium statistical mechanics as the most likely behavior of a system in […]
PICS Colloquium: Flow and heat transfer over rough walls: fundamental physics, numerical simulations, and bulk parametrizations with Elie Bou-Zeid
Understanding the physical processes modulating the transport of scalars, such as heat, over very rough surfaces is essential for understanding the thermal environment of cities, how wind and solar farms […]
PICS Colloquium: Influence of particle size distribution on random close packing with Eric Weeks
The volume fraction phi for random close packed (RCP) spheres is approximately 0.64. It is well known that higher RCP volume fractions are achieved by using collections of particles with […]
PICS Colloquium: Powering decarbonization with modeling and optimization of renewables in the multi-scale atmosphere with Michael F. Howland
To meet net-zero carbon emissions targets by mid-century, up to a ~30-fold increase in wind power capacity is required. Acceleration to this rate requires urgent improvements to efficiency and reliability […]
PICS Colloquium: Complex Polymer Design in the Age of AI: Why, What, and How?
Polymers are essential to a wide range of technologies, yet designing them with targeted structural and functional properties remains a grand challenge. A major opportunity lies in applying machine learning […]
PICS Colloquium: Enabling computationally efficient first-principles kinetic simulations in nanoporous catalysts using machine learning and data science with Brandon Bukowski
Machine learning tools have tremendous potential to accelerate computationally complex physics-based simulations. One example is the need to accelerate materials discovery through first-principles Density Functional Theory (DFT) calculations. This seminar […]
