Testing the performance of the Milanković telescope
A. Vudragović, M. Bílek, O. Müller +2
We have undertaken a multi-band imaging campaign of several galaxies to study their low surface brightness features such as shells and streams. Using the 1.4-m Milanković telescope…
From bypass transition to flow control and data-driven turbulence modeling: An input-output viewpoint
Mihailo R. Jovanović
Transient growth and resolvent analyses are routinely used to assess non-asymptotic properties of fluid flows. In particular, resolvent analysis can be interpreted as a special cas…
Provably Efficient Safe Exploration via Primal-Dual Policy Optimization
Dongsheng Ding, Xiaohan Wei, Zhuoran Yang +2
We study the Safe Reinforcement Learning (SRL) problem using the Constrained Markov Decision Process (CMDP) formulation in which an agent aims to maximize the expected total reward…
Convergence and sample complexity of gradient methods for the model-free linear quadratic regulator problem
Hesameddin Mohammadi, Armin Zare, Mahdi Soltanolkotabi +1
Model-free reinforcement learning attempts to find an optimal control action for an unknown dynamical system by directly searching over the parameter space of controllers. The conv…
Modal stability analysis of viscoelastic channel and pipe flows using a well-conditioned spectral method
Gokul Hariharan, Mihailo R. Jovanović, Satish Kumar
Modal stability analysis provides information about the long-time growth or decay of small-amplitude perturbations around a steady-state solution of a dynamical system. In fluid fl…
Simulation and stability analysis of oblique shock wave/boundary layer interactions at Mach 5.92
Nathaniel Hildebrand, Anubhav Dwivedi, Joseph W. Nichols +2
We investigate flow instability created by an oblique shock wave impinging on a Mach 5.92 laminar boundary layer at a transitional Reynolds number. The adverse pressure gradient of…
