    • Fall 2022 GRASP Seminar: Guillermo Gallego, Technical University Berlin, “Stereo depth and optical flow estimation via contrast maximization of event camera data”

    /
    Levine 307 3330 Walnut Street, Philadelphia, PA, United States

    *This is a HYBRID Event with in-person attendance in Levine 307 and virtual attendance via Zoom. ABSTRACT Event cameras are novel vision sensors that mimic functions from the human retina and offer potential advantages over traditional cameras (low latency, high speed, high dynamic range, etc.). They acquire visual information in the form of pixel-wise brightness […]

    MEAM Ph.D. Thesis Defense: “Room-temperature Electrochemical Healing of Structural Metals”

    /
    Greenberg Lounge (Room 114), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    For over 6,000 years, repairing high-strength metallic materials has required high temperatures and large energy inputs. Likewise, recent innovations in self-healing and repairable metals have remained limited by the need for heating, the small size of repairable cracks, and the low strength and constrained chemical composition of healed metals. While welding remains the most widely […]

    MEAM Seminar: “Harnessing Physical Intelligence for High-Performance Soft Robots”

    /
    Towne 227 (MEAM Conference Room) 220 S. 33rd Street, Philadelphia, PA, United States

    Different from neuron-based computational intelligence through the brain, physical intelligence leverages structural designs and smart materials to physically encode sensing, actuation, control, adaption, and decision-making into the body of an agent. The stimuli-responsive body materials can enable autonomous sensory, actuation, powering, and other physical intelligence functions. The structural designs of soft body can simplify the […]

    POSTPONED // MSE Seminar & Grace Hopper Lecture: “Materials for Quantum Technologies Through a Computational Lens”

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

    Refreshments served at 10:15 AM In this talk, I will describe theoretical and computational strategies based on quantum mechanical calculations, aimed at predicting material properties suitable for the development of quantum technologies. Specifically, I will discuss the electronic structure and coherent states of spin defects in two- and three-dimensional semiconductors and insulators, obtained using both classical […]

    PRECISE Seminar: Investigate and Mitigate the Attacks Caused by Out-of-Band Signals

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

    Abstract Sensing and actuation systems are entrusted with increasing intelligence to perceive the environment and react to it. Their reliability often relies on the trustworthiness of sensors. As process automation and robotics keep evolving, sensing methods such as pressure/temperature/motion sensing are extensively used in conventional systems and rapidly emerging applications. This talk aims to investigate […]

    • MEAM Seminar: “Manipulation of Micro/Nano Particles Using Acoustic Waves”

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

    Manipulation of particles in micro and nano scale has been invaluable in a variety of scenarios in applied physics, chemistry and biomedicine. Acoustic microfluidics has emerged as a powerful and novel platform for micro/nano manipulation in many applications recently due to its advantages in versatility, low cost, easy to integrate and manufacture, miniaturization, energy efficiency, […]

    Penn Engineering 2021-22 Heilmeier Award Lecture: Ritesh Agarwal

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

    "Utilizing Quantum Geometry and Topology for Enabling Integrated Chiral Photonics" Classical and quantum computing devices need to ferry vast amounts of data, and optical interconnects provide a promising approach allowing faster speeds and larger bandwidths. Critical interconnect components are light sources, waveguides and detectors. Currently, the information is encoded in intensity and frequency but other […]

    ASSET Seminar: Learning with Small Data, Pratik Chaudhari (University of Pennsylvania)

    /
    Levine 307 3330 Walnut Street, Philadelphia, PA, United States

    Abstract: The relevant limit for machine learning is not N → infinity but instead N → 0. The human visual system is proof that it is possible to learn categories with extremely few samples. This talk will discuss steps towards building such systems and it is structured in three parts. The first part will discuss […]

    Fall 2022 GRASP SFI: Ross Hatton, Oregon State University, “Snakes & Spiders, Robots & Geometry”

    /
    Room 307, Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    *This will be a HYBRID Event with in-person attendance in Levine 307 and Virtual attendance via Zoom here… ABSTRACT Locomotion and perception are a common thread between robotics and biology. Understanding these phenomena at a mechanical level involves nonlinear dynamics and the coordination of many degrees of freedom. In this talk, I will discuss geometric approaches […]
