PICS Colloquium: “Transforming Healthcare from the Outside: the OBSERVER project”

We live with a health care system that has evolved into an increasingly fragmented, primarily treatment-oriented, and now heavily burdened environment.  More importantly, issues related to privacy, space, and disease transmissibility have limited access to non-medical personnel who might offer creative, evidence-based, radical change to the health care system, as proposed years ago by the […]

PICS Colloquium “The Dynamics of Gas-Particle Partitioning: Insights from Laboratory, Field, and Modeling studies”

Abstract: Ultrafine aerosols can significantly influence Earth’s climate if they are able to grow to sizes large enough to interact with the incoming solar radiation and nucleate cloud droplets. In clear air, aerosol growth occurs via gas-to-particle conversion of condensable trace gases, including sulfuric acid, nitric acid, hydrochloric acid, ammonia, and myriad oxidation products of […]

PICS Colloquium: “Preserving microscale features in continuum models of fiber network materials”

Fiber networks at different length scales represent a prevalent microstructure of highly deformable materials and biological matter. At the microscale, these fiber networks are key for the function of biological systems, while at the macroscale they endow materials with striking characteristics, such as unusual kinematic behavior and high defect tolerance. Resolving the microstructure in discrete […]

PICS Colloquium: “Taking a layman’s perspective to turbulence modeling”

Abstract: Turbulence is an unsolved problem in classical physics. Its modeling often involves physical, mathematical, and numerical concepts that are daunting to even experienced engineers. This makes it very hard for a user to take a turbulence model from the literature and apply it in real-world engineering. This talk will take a layman’s perspective to […]

PICS Colloquium: “Computational Image Analysis For Individualized Surgical Treatment Planning of Bicuspid Aortic Valves”

Abstract: The bicuspid aortic valve (BAV) is a congenital heart defect in which the aortic valve has two cusps rather than three. Moderate to severe aortic regurgitation is the most common complication in young adult BAV patients and requires major, and often repeated, surgical intervention. BAV repair is an evolving surgical treatment for aortic regurgitation […]

PICS Colloquium: “Mechanics of Polymeric Gels”

This talk discusses recent and ongoing research on the multiphysics response of polymeric gels. A polymeric gel is a polymeric material swollen by a fluid, and the intake or out-flow causes large deformations. Also, many gels respond to environmental stimuli such as temperature, electric and magnetic fields, pH, and more. The responsiveness of polymeric gels […]

PICS Colloquium “Driving physics of inverted flag flapping”

Abstract: Fluid-structure interaction (FSI) is ubiquitous in the natural and engineered world, and a better understanding of FSI systems can aid in the design of renewable energy harvesting technologies, bio-inspired propulsion vehicles, and biomedical devices (to name a few applications). In this talk we will investigate “inverted” flag flapping, in which the flag is clamped at its […]

MEAM Seminar: “Uncovering the Rules of Crumpling with a Data-Driven Approach”

When a sheet of paper is crumpled, it spontaneously develops a network of creases. Despite the apparent disorder of this process, statistical properties of crumpled sheets exhibit striking reproducibility. Recent experiments have shown that when a sheet is repeatedly crumpled, the total crease length grows logarithmically [1]. This talk will offer insight into this surprising […]

MEAM Seminar: “Continuum Mechanics of Non-equilibrium Phenomena: A Journey Through Space and Time Scales”

The fascinating diversity of material behavior at the macroscopic scale, including plasticity, phase transformations, viscoelasticity or diffusion, can only emerge from the underlying atomistic or particle behavior. Yet, the direct connection between these two scales for non-equilibrium phenomena remains an extremely challenging quest from both a theoretical and computational perspective. This knowledge gap currently hinders […]

PICS Colloquium: “Computational and Experimental Modeling of Membrane Distillation”

Abstract: Computational fluid dynamics simulations and experiments were conducted to study the performance of distillation membrane process for water treatment and desalination applications. Polarizations and fouling/scaling in a direct contact membrane distillation module were examined. Laminar and turbulent flow regimes in the feed and permeate channels were considered. The hydrophobic membrane separates feed and permeate […]
