ESE Seminar: “Demystifying the Efficiency of Reinforcement Learning: Two Recent Stories”

https://upenn.zoom.us/j/96715197752

Reinforcement learning (RL), which is frequently modeled as sequential learning and decision making in the face of uncertainty, is garnering growing interest in recent years due to its remarkable success in practice. In contemporary RL applications, it is increasingly more common to encounter environments with prohibitively large state and action space, thus imposing stringent requirements on the […]

MEAM Seminar: “Surface and Interface Engineering in Manipulation and Fabrication of Colloid-Based Sub-Microporous Hierarchical Materials and Their Applications”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Micro- and nano-porous hierarchical materials exhibit extraordinary mechanical, energy conversion, and optical properties, but manufacturing challenges prevent them from being fabricated at cm-length scales or larger while maintaining the dense regular nm features that enhance their properties. Using self-assembled particles as a template to fabricate metallic hierarchical structures is promising to overcome these challenges, but […]

MEAM Seminar: “Room-Temperature Electrochemical Healing of Structural Metals”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Many biological materials and organisms, such as bones and mollusks, possess the capability to heal and repair fractures at room temperature or at low homeostatic temperatures (∼ 20 ◦C – 40 ◦C). While this healing capability has inspired many advances in room-temperature self-healing polymers, metals have proven more difficult to heal at room temperature due […]

MEAM Seminar: “Mechanical Properties of Fibrous Network Materials”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Fibrous network materials are ubiquitous both in nature and in synthetic materials, and therefore it is important to understand the general properties of the materials and the physics and microstructures on which those properties depend. Specifically, since fibrous networks generally perform a structural function, their mechanical properties are of critical importance. We discuss here certain […]

MEAM Seminar: “Dynamic Response of Resonant Metamaterials and Other Composites”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Composite materials under dynamic loading exhibit interesting emergent phenomena. Most notably are phononic crystals and metamaterials which can possess frequency dependent and negative elastic moduli and density. In general, the constitutive response is non-local in space and time and depends on both the strain and velocity. Additionally, scattering and local resonance effects can lead to […]
