Non-Uniform Stability, Detectability, and, Sliding Mode Observer Design for Time Varying Systems with Unknown Inputs
Markus Tranninger, Sergiy Zhuk, Martin Steinberger +2
This paper discusses stability and robustness properties of a recently proposed observer algorithm for linear time varying systems. The observer is based on the approximation and s…
Exponentially convergent data assimilation algorithm for Navier-Stokes equations
Jason Frank, Tigran Tchrakian, Sergiy Zhuk
The paper presents a new state estimation algorithm for a bilinear equation representing the Fourier- Galerkin (FG) approximation of the Navier-Stokes (NS) equations on a torus in…
Localised sequential state estimation for advection dominated flows with non-Gaussian uncertainty description
Emanuele Ragnoli, Mykhaylo Zayats, Fearghal O'Donncha +1
This paper presents a new iterative state estimation algorithm for advection dominated flows with non-Gaussian uncertainty description of -type: uncertain initial conditi…
Minimax state estimates for abstract Neumann problems
Alexander Nakonechnyi, Sergiy Zhuk
The paper presents analytic expressions of minimax (worst-case) estimates for solutions of linear abstract Neumann problems in Hilbert space with uncertain (not necessarily bounded…
Where computer vision can aid physics: dynamic cloud motion forecasting from satellite images
Sergiy Zhuk, Tigran Tchrakian, Albert Akhriev +2
This paper describes a new algorithm for solar energy forecasting from a sequence of Cloud Optical Depth (COD) images. The algorithm is based on the following simple observation: t…
General Optimization Framework for Robust and Regularized 3D Full Waveform Inversion
Stephen Becker, Lior Horesh, Aleksandr Aravkin +1
Scarcity of hydrocarbon resources and high exploration risks motivate the development of high fidelity algorithms and computationally viable approaches to exploratory geophysics. W…
