MEAM Seminar: “Flows About Superhydrophobic Surfaces”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Superhydrophobic surfaces, formed by air entrapment within the cavities of hydrophobic solid substrates, offer a promising potential for hydrodynamic drag reduction. In several of the prototypical surface geometries the flows are two-dimensional, governed by Laplace’s equation in the longitudinal problem and the biharmonic equation in the transverse problem. Moreover, low-drag configurations are typically associated with […]

MEAM Master’s Thesis Defense: “Gaussian Process-Based Active Exploration Strategies in Vision and Touch”

Meyerson Hall, Room B2 210 S. 34th Street, Philadelphia, PA, United States

Robots struggle to understand object properties like shape, material, and semantics due to limited prior knowledge, hindering manipulation in unstructured environments. In contrast, humans learn these properties through interactive multi-sensor exploration. This work proposes fusing visual and tactile observations into a unified Gaussian Process Distance Field (GPDF) representation for active perception of object properties. While […]

MSE Seminar: “Probabilistic Digital Twins for Structure Preserving Simulation and Scientific Discovery”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Despite the recent flurry of work employing machine learning to develop surrogate models to accelerate scientific computation, the "black-box" underpinnings of current techniques fail to provide the verification and validation guarantees provided by modern finite element methods. In this talk we present a data-driven finite element exterior calculus for building accelerated reduced-order models of multiphysics […]

MEAM Master’s Thesis Defense: “The Rheology and Microphysics of Monodisperse Synthetic Mucin”

Room 2C8, David Rittenhouse Laboratory Building 209 South 33rd Street, Philadelphia, PA, United States

Mucus, a complex fluid produced by every living organism, has multiple essential functions including acting as an effective barrier layer in various bodily processes, many of which involve important rheological (flow) and tribological (adhesive, lubricative) functions. The primary component of mucuses are mucins – highly glycosylated, linear polypeptides. Understanding how the structure and properties of […]

Towne 327

Entrepreneurship Seminar Series: Pathways to Impact This session brings together a panel of current and former faculty and PhDs that have brought their technology to market and have worked in both academia and commerce. Panelists will discuss the opportunities and approaches they took to create companies, leverage experience in academia, and drive research into commercial […]

MEAM Master’s Thesis Defense: “Modeling Off-Grid Photovoltaics Integrated with Micro-Cogeneration and Electrical Energy Storage”

Room 2C6, David Rittenhouse Laboratory Building 209 S. 33rd Street, Philadelphia, PA, United States

Due to the elevated expenditure of fossil fuels and their adverse impacts on climate change resulting from greenhouse gas emissions, it is imperative to integrate clean energy sources alongside fossil fuels. This study presents the design, simulation, and optimization of an integrated system comprising solar photovoltaics, micro-cogeneration, and electrical energy storage to achieve energy self-sufficiency […]

MEAM Seminar: “Collective Transitions in Beating Cilia and Swimming Fish”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

I will discuss the collective modes that spontaneously emerge in ciliary carpets and fish schools. In both systems, the fluid medium couples the motion of individuals in the group. Flow coupling is dominated by viscous forces in cilia and by inertial interactions in fish. I will show, numerically and analytically in the continuum limit, that […]

MEAM Seminar: “The Mechanics of Animal Collective Behavior: From Insect Swarms to Fish Schools”

David Rittenhouse Laboratory Building, Room A5 209 S. 33rd Street, Philadelphia, PA, United States

An incredible diversity of organisms, from bacteria and social insects to bird flocks and fish schools, self-organize to achieve collective tasks. They have inspired the development of decentralized algorithms and robotic swarms. While numerous models have been proposed to understand the self-organization of animal groups, the role of mechanics was rarely considered. In this talk, […]

MEAM Seminar: “Computational FSI Modeling of the Cardiovascular System”

Moore 212

Computational modeling and simulation has become a routine part of cardiovascular clinical research. These techniques leverage medical imaging to construct patient-specific models that can be used to study disease processes, design and evaluate medical devices, perform predictive surgery, and aid in clinical decision-making. Modern cardiovascular simulations often require millions of elements and tens of thousands […]
