Talk Title: Solving Heat Transfer and Fluid Flow Problems with Reduced Order Models and Neural Networks
Speaker: Dr. Zilong Song Department of Math & Stat, USU
Abstract: The friction stir welding process can be modelled using a system of heat transfer and Navier-Stokes equations with a shear dependent viscosity. Finding numerical solutions of this system of nonlinear partial differential equations over a set of parameter space, however, is extremely time-consuming. Therefore, it is desirable to find a computationally efficient method that can be used to obtain an approximation of the solution with acceptable accuracy. In this talk, we present a reduced basis method for solving the parametrized coupled system of heat and Navier-Stokes equations using a proper orthogonal decomposition (POD). In addition, we apply a machine learning algorithm based on an artificial neural network (ANN) to learn (approximately) the relationship between relevant parameters and the POD coefficients. Our computational experiments demonstrate that substantial speed-up can be achieved while maintaining reasonable accuracy.
Interaction Between Low-level Jets and Wind Turbine Arrays

Research Seminar Series presentation
Ecology Center Seminar Series - Dr. Beth Rose Middleton Manning
Conference/Seminar
Dr. Beth Rose Middleton Manning (Afro-Caribbean, Eastern European) is a Professor of Native American Studies at UC Davis. Beth Rose’s research centers on Native environmental policy and Native activism for site protection using conservation tools. Her broader research interests include intergenerational trauma and healing, rural environmental justice, indigenous analysis of climate change, Afro-indigeneity, and qualitative GIS.
Investigations of Turbulent Multiphase Flows Using Optical Measurement Techniques
Conference/Seminar
Small inertial particles in turbulence appear in a number of environmental flows such as dust, sand, rain, snow or sediment in the atmospheric boundary layer, in rivers, during deep-sea mining or on Mars. Particle dynamics, including accelerations and concentrations, depend (among other things) on gravity and inertia. In this talk I will present results of recent high-Reynolds-number experiments of inertial particles in turbulence which are performed in a turbulence box (Re? = 450) and an atmospheric boundary layer wind tunnel (Ret = 19,000). These results are of direct use in prediction and modeling of phenomena such as droplet growth in clouds, fall speed of snowflakes and particle concentrations in dust storms.

Reducing the Harm & Stigma of Opioid Use Disorder
Conference/Seminar
Communities benefit from reducing the stigma and helping prevent harm caused by opioid misuse, including overdose and disease, by building understanding and support for recovery and growth through evidence-based best practices. YOU can make a difference.
Join the Utah State University Extension's Tribal & Rural Opioid Initiative Resource Center on Monday, September 20 at 6:30 pm MDT, to learn about harm reduction strategies for opioid misuse treatment and overdose prevention. Dr. Erin Manning, Wayne State University School of Medicine Associate Professor, will present topics that are proven to address opioid misuse, including stigma reduction, person-first language, naloxone education, syringe exchange, and medication-assisted treatments.
* Treatment professionals may qualify for 1 CEU by completing required evaluations and the complete training session.

Title: Sensitivity analysis and uncertainty quantification using novel physics-constrained machine learning
Speaker: Dr. Hamidreza Karbasian, Fields Institute, University of Toronto
Abstract:
A new physics-constrained data-driven approach is proposed for sensitivity analysis and uncertainty quantification of large-scale chaotic dynamical systems. Unlike conventional sensitivity analysis, this approach can solve the unsteady sensitivity function for PDE-constrained optimizations. In this new approach, high-dimensional governing equations, such as Navier-Stokes equations, from physical space are transformed into an unphysical space to develop a closure model in the form of a Reduced-Order Model (ROM). Subsequently, a new data sampling approach is proposed to build a data-driven approach for this framework. It is shown that the proposed approach can capture sensitivities for large-scale chaotic dynamical systems, where Finite Difference (FD) approximations fail ...
