October 24, 2023 -ESE Fall Seminar – “Acceleration by Stepsize Hedging”
MEAM Seminar: “Granular and Photoelastic Avalanches”
Flowing granular materials arise everywhere around us, in industry from pharmaceutical processes to bulk good transport lines, and in nature from snow avalanches to captivating dune fields. In landslides, we have an interesting interplay between microscale (grain-grain contacts) and macroscale processes (continuum behavior). In order to understand critical macroscale processes such as stability of a […]
ESE Fall Seminar – “Acceleration by Stepsize Hedging”
Can we accelerate convergence of gradient descent without changing the algorithm --- just by optimizing stepsizes? Surprisingly, we show that the answer is yes. Our proposed Silver Stepsize Schedule optimizes strongly convex functions in $k^{\log_p 2} = k^{0.7864}$ iterations, where $p=1+\sqrt{2}$ is the silver ratio and $k$ is the condition number. This is intermediate between […]

ASSET Seminar: “Towards a Design Flow for Verified AI-Based Autonomy” (Sajit A. Seshia, University of California, Berkeley)
ABSTRACT: Verified artificial intelligence (AI) is the goal of designing AI-based systems that have strong, ideally provable, assurances of correctness with respect to formally specified requirements. This talk will review the main challenges to achieving Verified AI, and the initial progress the research community has made towards this goal. A particular focus will be on […]
Fall 2023 GRASP SFI: Matthew D. Kvalheim, University of Maryland, Baltimore County, “Discovering engineering (im)possibilities with geometry and topology”
This is a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT I will describe engineering (im)possibilities discovered with geometry or topology. These provide or revoke “hunting licenses” for the search of quantities of interest in three contexts: feedback control, applied Koopmanism, and deep neural network autoencoders. Control-Lyapunov or barrier […]
CBE Seminar: “Transformer-based Hybrid Modeling and Control of Evolving, Nonlinear Processes” (Kwon, Texas A&M University)
Traditionally, the dynamic modeling of chemical processes has relied on first-principles models grounded in fundamental physics and chemistry laws. These models, primarily formulated through differential equations with constant parameters, enable the calculation of control actions optimizing process operations, taking both process and actuator limitations into account. However, the ever-evolving and nonlinear nature of chemical processes […]

October 26, 2023 -PRECISE Seminar: Machines that Talk to the Brain and Think Like the Mind
MSE Seminar: “Advanced Analytical Characterization of Next Generation Energy Storage Systems” – Nik Singh – Toyota Research Institute of North America
Advances in hybrid and electric vehicle technologies combined with a demand for green initiatives have recently motivated necessary diversification in energy storage research. To achieve customer expectations for hybrid and electric vehicles, new battery systems with higher energy densities, power densities and cycle life than the current state-of-art Lithium (Li)-ion battery are needed. Further, to […]
PRECISE Seminar: Machines that Talk to the Brain and Think Like the Mind
Abstract Communicating with the brain enables us to advance our understanding of brain function, treat disorders, restore lost function, and when combined with artificial cognitive frameworks, can push the frontier of human capabilities. Key to realizing brain communication and replicating cognition are new computer architectures– systems that directly sense and stimulate the brain, and those […]

PRECISE Seminar: “Communication and Sensing with Laser Light”
Abstract The physical properties of laser light make it a perfect medium for a plethora of applications. Examples include high-bandwidth data communication thanks to its fast modulation speed, efficient power delivery given its high energy density, and fine-grained human sensing and object tracking because of its nanometer-level wavelength. Despite its potential, laser light still faces […]
Fall 2023 GRASP on Robotics: Nick Gravish, University of California, San Diego, “Adaptive robots through reconfiguration, compliance, and contact”
This is a hybrid event with in-person attendance in Wu and Chen and virtual attendance on Zoom. ABSTRACT Recent advances in robot materials and algorithms have enabled new levels of adaptive and versatile behavior. In this talk I will describe my lab’s efforts to create robots, mechanisms, and control algorithms capable of adaptive behaviors in […]
ESE Fall Seminar – “Quantum sensing and imaging with diamond spins”
Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale imaging of condensed matter and biological systems with sensitivity to single nuclear spins. Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems, where we have imaged current flow patterns in graphene […]
PICS Colloquium: “Modeling Assembly of Colloids with Charges and with Mobile Binders”
In this talk, I will present our recent efforts in probing the physical processes underlying self-assembly of colloidal gels and crystals. Nano-meter to micron sized particles in suspension can be a powerful platform for assembly novel functional materials, but the challenge is to design interactions such that desired functionality is achieved. Moreover, for practical purposes […]
