Time Delay Extraction from Frequency Domain Data Using Causal Fourier Continuations for High-Speed Interconnects
Lyudmyla L. Barannyk, Hung H. Tran, Aicha Elshabini +1
We present a new method for time delay estimation using band limited frequency domain data representing the port responses of interconnect structures. The approach is based on the…
On Artifacts in Limited Data Spherical Radon Transform: Curved Observation Surface
Lyudmyla L. Barannyk, Jürgen Frikel, Linh V. Nguyen
In this article, we consider the limited data problem for spherical mean transform. We characterize the generation and strength of the artifacts in a reconstruction formula. In con…
Spectrally Accurate Causality Enforcement using SVD-based Fourier Continuations for High Speed Digital Interconnects
Lyudmyla L. Barannyk, Hazem A. Aboutaleb, Aicha Elshabini +1
We introduce an accurate and robust technique for accessing causality of network transfer functions given in the form of bandlimited discrete frequency responses. These transfer fu…
Kinetic equation for spatially averaged molecular dynamics
Alexander Panchenko, Kevin Cooper, Andrei Kouznetsov +1
We obtain a kinetic description of spatially averaged dynamics of particle systems. Spatial averaging is one of the three types of averaging relevant within the Irwing-Kirkwood pro…
Optimizing performance of the deconvolution model reduction for large ODE systems
Lyudmyla L. Barannyk, Alexander Panchenko
We investigate the numerical performance of the regularized deconvolution closure introduced recently by the authors. The purpose of the closure is to furnish constitutive equation…
Deconvolution closure for mesoscopic continuum models of particle systems
Alexander Panchenko, Lyudmyla L. Barannyk, Kevin Cooper
The paper introduces a general framework for derivation of continuum equations governing meso-scale dynamics of large particle systems. The balance equations for spatial averages s…
