This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. ABSTRACT If I show you a photo of a place you have never been to, you can easily imagine what you could do in that picture. Your understanding goes from the surfaces you see to the ones […]
Fall 2022 Hybrid-Seminar Series Mondays 1.00-2.00 pm (EST) Towne 225 / Raisler Lounge For Zoom link, please contact <manu@seas.upenn.edu
This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Area coverage path planning is the problem of finding an efficient path that traverses the region of interest while avoiding existing obstacles. When dealing with real systems, the dynamic changes and uncertainties of the environments increase the […]
ABSTRACT Machine learning traditionally does not get at causality and causality research traditionally treats machine learning as a dangerous set of highly biased estimators. In my talk I will talk about our lab’s efforts to use machine learning as a component of more traditional quasi-experimental techniques. I will also discuss meta-learning approaches to causal inference, […]
A large fraction of cell and tissue mass is made of water. The flow of water across the cell surface follows osmotic and hydraulic pressure gradients, and is actively controlled by the cell. This physical fact suggests that the mechanical behavior of cells is intimately connected with cell ionic homeostasis and osmotic control. In this […]
In nature, organized arrays of elements arise spontaneously from the interactions between their component parts, e.g. reaction-diffusion problems, clustering colloidal particles and granular media, wrinkling surfaces, propagating cracks and flowing liquids. In the wake of biomimicry, I will discuss several strategies aiming to harness mechanical instabilities in flowing liquids, e.g. coiling, droplet formation, digitation, drainage, […]
Multifunctional soft materials and interfaces create intriguing new opportunities to enhance performance through programmable and adaptable properties. I will discuss: 1) Novel material architectures of solid-liquid soft composites for electronics, 2) Switchable and programmable materials for adhesion control, and 3) Morphing materials for soft robotics. For soft composites, I will show how liquid metal droplets […]
Presentation Abstract: Faced with unlabeled data in deployment that is sampled from a different distribution than that which generated the training data, all bets are off. Moreover, while numerous heuristics have been proposed for this vague setting, it remains unclear when any among them are applicable. One way to render these problems identifiable is to […]
This is a hybrid event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Philadelphia Robotics Coalition founder, and School District of Philadelphia engineering teacher Michael Johnson discusses how Philadelphia public schools are using the competitive FIRST robotics programs to build STEM equity in our city. With the goal to inspire and prepare the next generation of STEM […]
Modern materials contain extraordinary levels of complexity, with components spanning a hierarchy of length scales. Designing materials with complex microstructures and demonstrating unique behaviors would be difficult solely using a reductionist approach to materials development. A powerful utility in this endeavor is using multiple, correlative, and scaffolding computational tools. This talk focused on using an […]
