    • MEAM Seminar: “Bistable Robots: Leveraging Task Features for Actuator Reduction”

    /
    Moore 212

    Actuator reduction is especially important for aerial robots, where minimizing mass and conserving power is critical. Bistable mechanisms have been used to augment actuators by speeding up actuation time or allowing one direction of actuation to be passive. In this talk we will explore how bistable mechanisms can reduce the number of actuators needed in […]

    Penn American Red Cross Blood Drive

    /
    Bodek Lounge, Houston Hall 3417 Spruce St, Philadelphia, PA, United States

    There is currently a critical need for blood donors, and members of the Penn Engineering community are invited to participate in a school-wide blood drive. To join in this effort, please RSVP using this link.

    • MEAM Seminar: “Mechanics- Informed Optimization for Enhanced Adhesion and Toughness”

    /
    Towne 337

    Structural design optimization has long played a crucial role in engineering, often with the goal of creating stiff and lightweight structures for aerospace and other applications. However, optimizing structures against failure is also crucial and has been much less well explored. Failure via fracture and at interfaces is particularly challenging in design optimization as they […]

    ESE PhD Thesis Defense: “Software/Hardware Co-optimization for Computer Systems with 3D-stacking Memories”

    /
    Moore 317 200 S 33rd Street, Philadelphia, PA, United States

    Emerging 3D memory technologies, such as the Hybrid Memory Cube (HMC) and High Bandwidth Memory (HBM), provide high bandwidth and massive memory-level parallelism. With the growing heterogeneity and complexity of computer systems (CPU cores and accelerators, etc.), efficiently integrating emerging memories into existing systems poses new challenges to both algorithm, hardware and system. This dissertation […]

    MEAM Seminar: “Wall-modeled Large-eddy Simulation of Non-Equilibrium Turbulent Boundary Layers”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Accurate prediction of high-Reynolds-number turbulent flows is essential for the understanding and flow control of many engineering applications such as aircraft, turbomachinery, and marine vehicles. Additionally, most practical flows exhibit nonequilibrium effects such as pressure gradients and flow separation. However, the direct numerical simulation (DNS) of high-Reynolds-number wall-bounded turbulent flows is not feasible owing to […]

    BE Doctoral Dissertation Defense: “Microfluidics for throughput scalable formulation of mRNA lipid nanoparticle technology” (Sarah Shepherd)

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

    The Department of Bioengineering at the University of Pennsylvania along with Drs. Dave Issadore and Mike Mitchell proudly announce the Doctoral Dissertation Defense of Sarah Shepherd.   Title: Microfluidics for throughput scalable formulation of mRNA lipid nanoparticle technology    Date:  August 10, 2023 Time: 3:00 PM Location: Wu & Chen Auditorium, Levine Hall   Zoom option: https://us04web.zoom.us/j/78754123595?pwd=P2UVNng5H6hZXibk3AylTxA9UcWA9o.1 Meeting ID: […]

    Summer 2023 GRASP Seminar: Claire Tomlin, University of California at Berkeley, “Safe Learning in Control”

    /
    GRASP Treehouse - Pennovation Complex; LAB Building (Bldg 250 - Suite 250) 3401 Grays Ferry, Philadelphia, United States

    This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom.   ABSTRACT In many applications of autonomy in robotics, guarantees that constraints are satisfied throughout the learning process are paramount. We present a controller synthesis technique based on the computation of reachable sets, using optimal control and game […]

    MEAM Seminar: “Hierarchical Methods for Geometric Control of Underactuated, Free-Flying Robotic Systems”

    /
    Towne 337

    Free-flying robotic systems (such as multibody aerial and space vehicles) evolve on high-dimensional non-Euclidean manifolds subject to nonlinear, underactuated dynamics. Because such systems can rely only on the severely limited computational resources available onboard, the design of general-purpose controllers capable of dynamic and reliable real-time performance remains a formidable challenge. To mitigate these obstacles and […]

    MEAM Ph.D. Thesis Defense: “Exploiting Flows for Orienteering and Planning Problems”

    /
    Towne 337

    Task and path planning algorithms for robots in the presence of flows confront a fundamental dichotomy between the continuous and the discrete: task planning algorithms discretize the world and their goals, whereas flows are continuous in nature. This contrast is exemplified in many robotic applications where environmental forces impact navigation and exploiting those flows is […]
