    • MSE Seminar: “Natural Structural Materials: Lessons on Toughening Mechanisms, Weight Reduction, and Multifunctionality” (Virginia Tech University)

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

    Structural materials that are damage tolerant, lightweight, multifunctional, and sustainable are highly desirable for many engineering applications. Such combinations of properties are often found in the biological world. Organisms from nature construct a variety of different biological structural materials for protection, predation, body support, camouflage, etc. Despite the fact that these materials are made from […]

    ESE & MEAM Seminar – “Enabling Self-sufficient Robot Learning”

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Autonomous exploration and data-efficient learning are important ingredients for helping machine learning handle the complexity and variety of real-world interactions. In this talk, I will describe methods that provide these ingredients and serve as building blocks for enabling self-sufficient robot learning. First, I will outline a family of methods that facilitate active global exploration. Specifically, […]

    BE Seminar: “Engineering therapeutic immunity using (nano)biomaterials” (Natalie Artzi, Harvard Medical School)

    /
    Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    This seminar will be held in person only; snacks will be provided. Immunomodulatory therapies have advanced to clinical trials over the past decade for the treatment of a range of diseases and disorders, from cancer to diabetes to transplant rejection. However, the efficacy of these therapies remains limited, as challenges associated with off-target drug toxicity, […]

    Spring 2023 GRASP on Robotics: Pulkit Agrawal, MIT, “Fun with Robots and Machine Learning”

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

    This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance via Zoom. This week's presenter will be in-person as well.    ABSTRACT Robots are getting smarter at converting complex natural language commands describing household tasks into step-wise instructions. Yet, they fail to actually perform such tasks! A prominent explanation for these […]

    Spring 2023 GRASP Seminar: Larry Matthies, Jet Propulsion Laboratory, California Institute of Technology, “Autonomous mobility in Mars exploration: recent achievements and future prospects”

    /
    Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    This is a hybrid event with in-person attendance in Berger Auditorium (Skirkanich Floor B) and virtual attendance via Zoom. This week's presenter will be in-person as well.    ABSTRACT This talk will summarize key recent advances in autonomous surface and aerial mobility for Mars exploration, then discuss potential future missions and technology needs for Mars […]

    • MEAM Seminar: “Wall-modeled Large-eddy Simulation of the Turbulent Boundary Layer with Mean-flow Three-dimensionality”

    /
    Towne 309 220 S. 33rd Street, Philadelphia, PA, United States

    The capability to predict high-Reynolds-number turbulent flows is essential for many natural and engineering flows such as external aerodynamics of wind turbines and aircraft wings, flow over the hull of marine vehicles, atmospheric boundary-layer flow over complex landscapes and cityscapes. However, due to extreme disparity of scales present in high-Reynolds-number wall-bounded turbulent flows, any attempt […]

    5th Annual Mechanobiology Symposium

    /
    Smilow Center Auditorium 3400 Civic Center Blvd, Philadelphia, PA, United States

    This two-day symposium is organized by the Center for Engineering MechanoBiology (CEMB) with support from the National Science Foundation. The theme will be MechanoImmunology and Epigenetics. The CEMB is a Science and Technology Center funded by the National Science Foundation; our research focus is to advance the study of mechanical forces in molecules, cells, and tissues in plants […]

    MEAM Seminar: “Material-Enabled Technologies for Soft and Fluidic Robots”

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

    The emerging field of soft robotics, which incorporates unconventional or compliant materials in autonomous systems, has simultaneously reshaped traditional robotics applications and introduced new use cases for robots. However, many useful classes of materials remain relatively unexplored, and furthermore, the vast majority of soft robotics research has targeted actuation and sensing, with power and control […]

    (Re)Connecting in the Classroom: Evan C Thompson Lecture on Excellence in Teaching

    /
    Van Pelt Library, Kislak Center, 6th Floor 3420 Walnut Street, Philadelphia, United States

    Lately there has been much talk in universities and the public about "the great disengagement." As we emerge from the pandemic era, many students and instructors alike are experiencing a lack of energy and motivation, and we are seeking encounters in the classroom that are transformative, rather than simply transactional. In this talk, Daeyeon Lee […]

    MEAM Ph.D. Thesis Defense: “Towards Digital Twins for Cardiovascular Flows: A Hybrid Machine Learning and Computational Fluid Dynamics Approach”

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

    To design personalized treatment strategies, a number of measurable quantities (biomarkers) that relate a patient’s clinical representation to the existence, progress, and outcome of a disease need to be identified and measured. In cases where a biomarker is strongly correlated with the disease outcome, e.g. vascular pressure for hypertension, changes to the biomarker will perfectly […]

    ASSET Seminar: Lockout: Sparse Regularization of Neural Networks, Gilmer Valdes (UCSF)

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

    ABSTRACT: Many regression and classification procedures fit a function f(x;w) of predictor variables x to data 〖{x_i,y_i}〗_1^N based on some loss criterion L(y,f(x;w)). Often, regularization is applied to improve accuracy by placing a constraint P(w)≤t on the values of the parameters w, where P is a monotonic increasing function of the absolute values of the […]
