Moving shape dynamics: A signal processing perspective [PDF]
, 2008 This paper provides a new perspective on human motion analysis, namely regarding human motions in video as general discrete time signals. While this seems an intuitive idea, research on human motion analysis has attracted little attention from the signal

Short vector code generation for the discrete Fourier transform [PDF]
Proceedings International Parallel and Distributed Processing Symposium, 2004 In this paper we use a mathematical approach to automatically generate high performance short vector code for the discrete Fourier transform (DFT). We represent the well-known Cooley-Tukey fast Fourier transform in a mathematical notation and formally derive a "short vector variant".

Quantum Walks, Quantum Gates and Quantum Computers [PDF]
, 2007 The physics of quantum walks on graphs is formulated in Hamiltonian language, both for simple quantum walks and for composite walks, where extra discrete degrees of freedom live at each node of the graph.

Fully solvable finite simplex lattices with open boundaries in arbitrary dimensions
Physical Review Research, 2023 Finite simplex lattice models are used in different branches of science, e.g., in condensed-matter physics, when studying frustrated magnetic systems and non-Hermitian localization phenomena; or in chemistry, when describing experiments with mixtures. An

Prediction of transonic 2D wing flutter using the time-spectral computational fluid dynamics
Journal of Fluid Science and Technology, 2022 A new computation method to predict a transonic wing flutter under the limit-cycle oscillation (LCO) is developed using the time spectral (TS) method. The fluid and structural unknowns at a specified time interval in one cycle of the flutter are obtained

Analysis of the applicability of filtration methods for coordinate measurements
MATEC Web of Conferences, 2018 At present, surface metrology solves such important tasks as monitoring the production process and optimizing the exploitation of parts. A significant part of the measurements is performed by a contact method using Coordinate Measuring Machines.
