Talk Title: High-Assurance Design Methods for Trustworthy Autonomous Cyber-Physical Systems
Abstract: Correctness and safety assurance is of utmost importance in mission-critical systems for various applications, for example, in avionics, automobiles, robotics, and manufacturing. In these systems, increasingly more sophisticated tasks that were previously allocated to humans are expected to be performed by software, including modern artificial intelligence (AI) methods. One of the biggest challenges to full autonomy is arguably in showing that these AI and autonomous software functions will still satisfy the stringent safety and correctness requirements of mission-critical systems in uncertain or unpredictable environments. In this talk, I will introduce our approach toward enhancing design-time assurance for trustworthy autonomous cyber-physical systems. I will present synthesis methods for correct-by-construction design of optimal control and reinforcement learning policies in uncertain and unknown environments with provable guarantees on the satisfaction of complex missions, expressed by temporal logic specifications. I will then introduce the rich specification formalism of stochastic assume-guarantee contracts for compositional, quantitative requirement analysis and system verification under uncertainty. Finally, I will discuss how stochastic contracts can provide the semantic foundation for the automated construction of assurance cases, structured arguments about system dependability, which can accelerate system certification and help transition from a process-driven to a property-driven certification approach.
Biography: Pierluigi Nuzzo is an Assistant Professor and the Kenneth C. Dahlberg Early Career Chair in the Department of Electrical and Computer Engineering at USC, where he is also the Associate Director of the Center for Autonomy and Artificial Intelligence. He received the PhD in Electrical Engineering and Computer Sciences from UC Berkeley, and BS and MS degrees in Electrical and Computer Engineering from the University of Pisa and the Sant'Anna School of Advanced Studies in Pisa, Italy. Before joining UC Berkeley, he held research positions at the University of Pisa and IMEC, Leuven, Belgium, working on analog and mixed-signal circuit design. His interests focus on methodologies and tools for high-assurance design of cyber-physical systems and systems-on-chip, including the application of formal methods and optimization theory to problems in embedded and cyber-physical systems, electronic design automation, requirement engineering, security, and artificial intelligence. He received the 2022 Early-Career Award from the IEEE Technical Committee on Cyber-Physical Systems, the DARPA Young Faculty Award in 2020, the NSF CAREER Award in 2019, and best paper and design competition awards from the International Conference on Formal Methods and Models for System Design (MEMOCODE), the International Conference on Cyber-Physical Systems (ICCPS), the Design Automation Conference (DAC) and the International Solid-State Circuit Conference (ISSCC). His awards also include the IBM PhD Fellowship, the UC Berkeley Outstanding Instructor Award, and the UC Berkeley EECS David J. Sakrison Memorial Prize for his doctoral research.

MFD Seminar: Mechanisms for Diffusion Dependent Interfacial Strain: New Insights for Ultrahigh Temperature In Situ TEM
Tue, Oct 18, 2022 @ 04:00 PM - 05:20 PM
Mork Family Department of Chemical Engineering and Materials Science
Conferences, Lectures, & Seminars
Speaker: Professor Shen J. Dillon, Professor of Materials Science and Engineering, University of California, Irvine
Talk Title: Mechanisms for Diffusion Dependent Interfacial Strain: New Insights for Ultrahigh Temperature In Situ TEM
Abstract: Series: MFD Distinguished Lecture Series
Polycrystals can exhibit high-temperature interface-mediated strain in response to an externally applied stress, such as creep, superplasticity, or hot-press sintering, or internal stress, such as stress relaxation at interfaces during thermal cycling or oxide scale growth, fission bubble growth, and densification during sintering. Such problems have mostly been analyzed and treated in the context of purely diffusional models. The diffusional flux, however, is one of only three necessary steps or conditions required for diffusional dependent interfacial strain, the other two include interfacial dislocation nucleation and the emission and absorption of point defects at the interfacial dislocations. The prevalence of diffusional rate limited models results from somewhat unsubstantiated assumptions within the early literature along with the non-uniqueness of the various rate-limiting kinetic models, i.e., disparate models often fit isothermal kinetic data obtained from polycrystalline experiments equally well.
Our group developed a laser heating-based approach for ultrahigh temperature in situ transmission electron microscopy (TEM) during small-scale mechanical testing. This approach enables a more direct characterization of interfacial strain kinetics and thermodynamics at individual grain boundaries, which provides an improved basis for evaluating the high-temperature deformation mechanisms. This talk will present experiments that reveal grain boundary dislocation nucleation limits interfacial strain kinetics in many systems up to relatively large stresses. Based on the experimental observations, new models for sintering and grain boundary creep are developed to account for the appropriate mechanism. These are demonstrated to fit experimental data well, predict broad trends in the literature, and provide explanations for several poorly understood phenomena within the sintering and creep literature. The talk will conclude by discussing the broader implications of the new scientific understanding.
Biography: Shen J. Dillon is a Professor in the Department of Materials Science and Engineering at the University of California Irvine. He received his B.S. and then Ph.D. in Materials Science and Engineering from Lehigh University in 2007. He began as an Assistant Professor at the University of Illinois at Urbana-Champaign in 2009 and joined the faculty at UC Irvine in 2021. His scientific interests relate to understanding the key role played by inorganic interfacial structure-property relationships in affecting the performance of systems in extreme environments. Much of his recent work relates to developing and applying novel in situ characterization techniques that can be applied to understanding the dynamic properties of materials and their interfaces. He is the author of over 100 articles and was a recipient of the 2011 Department of Energy Early Career Award, the 2013 National Science Foundation CAREER Award, and the 2015 American Ceramic Society's Robert L. Coble Award for Young Scholars.
