Special Seminar: “Mechanics of Metamaterials – Combining in situ Experimentation and Machine Learning Modeling”

April 14 @ 10:00 am - 11:00 am

Abstract:  Metamaterials are synthetic materials engineered to have properties not found in naturally occurring materials. They are being designed for a broad set of applications ranging from light modulation, wearable electronic devices, microrobotics, and energy dissipation and redirection to mention just a few. In this seminar, I will discuss two classes of metamaterials we have investigated, origami and kirigami metamaterials, and 2D metamaterials. Origami and kirigami have their origin in Japanese art, one based on paper folding and the other…

Dr. Carl Zorowski Distinguished Lecture Series Seminar: Dr. Venkat Krovi

April 15 @ 10:00 am - 11:00 am

About the Dr. Carl Zorowski Distinguished Lecture Series: The Dr. Carl Zorowski Distinguished Lecture Series is dedicated to late MAE Department head, Reynolds Professor Emeritus, and 60-year veteran of the College of Engineering: Dr. Carl Zorowski. Dr. Zorowski passed away April 5, 2021, and since then, his legacy as an invaluable educator and engineering professional at NC State has lived on through his students and through his many contributions to the MAE Department. Dr. Zorowski was an incredibly influential figure in…

Visitor Seminar: “Sorption‐based Selective Gas Management: from Microscale Physics to Macroscale Systems”

April 21 @ 10:00 am - 11:00 am

Abstract: The Size, Weight, Power, and Cost (SWaP‐C) of a wide range of energy‐related systems depend on selective gas management (i.e., capture, rejection, and storage) of candidate species in a multi‐species gas stream. Particularly, selective gas management is central to the advancement of two emerging areas of air conditioning (AC) and spacecraft crew‐generated carbon dioxide removal systems for life support on earth and in space. For air conditioning systems, effective and/or independent humidity management is a key concept to the…

MAE Seminar: “New Frontiers for Materials and Mechanics: From Health to Energy and the Environment”

April 22 @ 10:00 am - 11:00 am

Abstract: This talk presents some materials and mechanics approaches to the design of solutions to selected problems in health, energy, and the environment. In the first part of the talk, we explore the use of adhesion and receptor-mediated endocytosis concepts in the bio-inspired design of targeted nanoparticles and drugs for the detection and treatment of breast cancer.  Micro-fluidic shear assay and nanoindentation techniques are used to develop mechanical biomarkers for the detection of breast cancer cells.  In the second part…

Visitor Seminar: “A Novel Computational Framework for the Numerical Solution of Complex Constrained Optimal Control Problems “

April 25 @ 10:00 am - 11:00 am

Abstract: A novel computational framework is described for solving complex constrained nonlinear optimal control problems.  The framework has a wide variety of applications in aerospace and mechanical engineering.  The basis of the framework is the new class of hp-adaptive Gaussian quadrature methods that transcribe the continuous optimal control problem to a finite-dimensional nonlinear optimization problem.  The hp-adaptive methods have the feature that high accuracy can be obtained with a significantly smaller mesh when compared with traditional fixed-order methods while accurately capturing nonsmoothness…

Visitor Seminar: “Orbital Perturbations and Stochastic Machine Learning Techniques for Space Situational Awareness (SSA) Applications “

April 26 @ 10:00 am - 11:00 am

Abstract: Safety of the near-Earth space environment, where we have many of our important assets like communication and reconnaissance satellites, ISS, space-based optical sensors, etc., is an ever-increasing concern because of the exploding number of satellite launches. Kessler’s Syndrome (the cascading phenomenon where space debris collisions create more debris and more collisions) may render this precious near-Earth space inaccessible. This seminar focuses on two topics: (a) novel analytic techniques for space situational awareness (SSA) applications (b) stochastic machine learning techniques…
