    • MEAM Seminar: “Understanding and Controlling Pattern Formation of Soft Materials”

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

    Soft elastic solids, such as elastomers and hydrogels, are used in many practical applications ranging from adhesives to biocompatible scaffolds for tissue engineering. Biological cells and tissues have very similar mechanical properties as those of soft materials. Such solids undergo large deformations and can respond to forces such as interfacial tension, gravity, and residual stresses […]

    MSE Seminar: “Controlling ferroelectricity at the nanoscale: from oxide heterostructures to freestanding crystalline membranes”

    /

    Complex oxides are fascinating material systems exhibiting a diverse set of electrical, magnetic, and thermal properties. In particular, ferroelectric oxides with an electrically switchable polarization and large dielectric and piezoelectric responses are considered as critical components for next-generation low-power logic devices, non-volatile memories, and nanoscale sensors and actuators, etc. Recent advances in thin-film synthesis techniques […]

    ESE Seminar: “Megahertz Power Electronics in Transportation and Healthcare Applications”

    /
    Zoom - Email ESE for Link jbatter@seas.upenn.edu

    The efficient use of electrical energy is a foundation of modern society. Power electronics is at the core of electrical energy conversion and greatly impacts a system’s size, performance, and cost. High-performance miniaturized power electronics can be a key enabling technology for many emerging applications, such as electric vehicles (EV), medical devices, and soft- and […]

    CIS Seminar: “Proof systems for governance, transparency, and privacy”

    /
    Zoom - Email CIS for link cherylh@cis.upenn.edu

    Record-keeping has long played a critical role in society, from governing property ownership to establishing historical "truth". Today, our dependence on digital records is becoming absolute, from our personal wealth, commerce, and identities to sources of knowledge and news. This has elevated the importance of three competing dimensions: Who has control over how records are […]

    ODEI Spotlight: Truth Telling, The Media, and Social Equity

    /

    Following Remarks by Penn President Amy Gutmann there will be a panel featuring: Andrea Mitchell - Chief Washington Correspondent and Chief Foreign Affairs Correspondent NBC News Jamil Smith - Emmy Award Winning Producer and Senior Writer Rolling Stone David Freedlander - Journalist and Author of The AOC Generation: How Millenials are Seizing Power and Rewriting […]

    ESE Seminar: “Demystifying (Deep) Reinforcement Learning: The Optimist, The Pessimist, and Their Provable Efficiency”

    /
    Zoom - Email ESE for Link jbatter@seas.upenn.edu

    Coupled with powerful function approximators such as deep neural networks, reinforcement learning (RL) achieves tremendous empirical successes. However, its theoretical understandings lag behind. In particular, it remains unclear how to provably attain the optimal policy with a finite regret or sample complexity. In this talk, we will present the two sides of the same coin, […]

    ODEI Spotlight: Inclusive Technology, Provocations for Research and Design

    /

    Abstract: Perceptions of digital technology have grown increasingly cynical over the last decade, fueled by crises from the Snowden leaks to Cambridge Analytica to disinformation campaigns.  Critical thinking about who is accommodated and who is excluded by mainstream technology is crucial for living up to promises of technology as empowering, but what do these reflections […]

    MEAM Seminar: “Control of Turbulent Wall Shear Flows and the Potential for ‘Designer Turbulence'”

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

    The financial and environmental cost of turbulence is staggering: manage to quell turbulence in the thin boundary layers on the surface of a commercial airliner and you could almost halve the total aerodynamic drag, dramatically cutting fuel burn, emissions and cost of operation. Yet systems-level tools to model scale interactions or control turbulence remain relatively […]

    ESE Seminar: “Surpassing Fundamental Limits through Time Varying Electromagnetics”

    /
    Zoom - Email ESE for Link jbatter@seas.upenn.edu

    Surpassing the fundamental limits that govern all electromagnetic structures, such as reciprocity and the delay-bandwidth-size limit, will have a transformative impact on all applications based on electromagnetic circuits and systems. For instance, violating principles of reciprocity enables non-reciprocal components such as isolators and circulators, which find application in full-duplex wireless radios, radar, bio-medical imaging, and […]

    CIS Seminar: “Human-AI Systems for Making Video Useful”

    /
    Zoom - Email CIS for link cherylh@cis.upenn.edu

    Video is becoming a core medium for communicating a wide range of content, including educational lectures, vlogs, and how-to tutorials. While videos are engaging and informative, they lack the familiar and useful affordances of text for browsing, skimming, and flexibly transforming information. This severely limits who can interact with video content and how they can […]
