Refreshments will be available.\r\n\r\nAbstract: Modern day engineering decision-making involves one or more computer simulation oracles of an engineered system which can be queried on-demand to learn the system response to control input. Querying simulation oracles, also called \u201ccomputer experiments\u201d, incur a non-trivial computational cost, which increases with the level of fidelity in the underlying models. For instance, a realistic computational aerodynamic simulation of an aircraft can cost several thousands of CPU hours to compute\u2014anything more than a few dozens of such simulations is prohibitive. Therefore, a central goal of engineering decision-making is to optimally design computer experiments, to maximize the value of information extracted at minimal computational effort.\r\nIn this talk, we will address problems anchored in, what we coin, the \u201cdecision-making triad\u201d which includes: surrogate modeling, uncertainty quantification (UQ), and numerical optimization\/control. Specifically, using variants of a probabilistic surrogate model and a Bayesian decision theoretic framework, we will show that problems in the decision-making triad can be solved in a principled, theoretically sound and, yet (computational) cost-effective manner. We will show demonstrations on applications in computational aerodynamics.\r\n\r\nSpeaker bio: Ashwin Renganathan is an assistant professor of aerospace engineering at Penn State and holds a joint appointment with the Penn State Institute of Computational and Data Sciences (ICDS). He directs the Computational complex engineered Systems Design Laboratory (CSDL) at Penn State. He is broadly interested in developing novel and scalable computational techniques for surrogate modeling, uncertainty quantification, and numerical optimization, with a focus on aerospace applications. He earned his Ph.D. in aerospace engineering from Georgia Tech and previously completed a postdoctoral appointment in applied mathematics at the Argonne National Laboratory.", "occurrence_notes":"This is a hybrid event.

No prior experience with meditation is required. \r\n\r\n*What will you learn?*\r\n\r\nThe guided meditation practice involves three simple steps: relaxation, rejuvenation, and meditation.\r\n\r\nRelaxation brings your body to a calm, steady posture creating a stillness at the physical level, and prepares the mind for meditation. We follow this with a rejuvenation method to detox the mind to let go of stress and complex emotions, and will leave you feeling light and refreshed. Lastly, learning to meditate by being mindful of your heart will connect you with yourself by listening to your heart\u2019s voice. \r\n\r\n*Why Meditate?*\r\n\r\nWhile physical fitness keeps our bodies in shape, meditation is an exercise for the mind and mental wellness. In addition to the measurable benefits mentally and physically, many people benefit from an unquantifiable inner poise and harmony. \r\n\r\n*Please take Learn to Meditate session if you are new to the practice.
