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 […]
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 […]
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 […]
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: […]
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 […]
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 […]
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 […]

Plasmonic nanostructure based on silver and gold that produces LSPR to withstand ultrahigh temperatures without damage remains a great challenge for future ultra-compact integrated circuits, and high-power enabled photonic devices. In principle, the shapes of plasmonic nanostructures containing noble metals would change after the heat treatment that altered the plasmonic resonance. Thus, discovering refractory plasmonic […]
