Lie-point symmetries of the discrete Liouville equation
The Liouville equation is well known to be linearizable by a point transformation. It has an infinite dimensional Lie point symmetry algebra isomorphic to a direct sum of two Virasoro algebras.

Estimation of DOA for Noncircular Signals via Vandermonde Constrained Parallel Factor Analysis
We provide a complete study on the direction-of-arrival (DOA) estimation of noncircular (NC) signals for uniform linear array (ULA) via Vandermonde constrained parallel factor (PARAFAC) analysis.

Dead‐time compensators (DTCs) are a family of classical controllers derived from the Smith Predictor. Their main characteristic is that they explicitly employ the model of the open‐loop process to feedback a predicted value of the non‐delayed system ...

Least Squares Ranking on Graphs [PDF]
Given a set of alternatives to be ranked, and some pairwise comparison data, ranking is a least squares computation on a graph. The vertices are the alternatives, and the edge values comprise the comparison data.

An introduction to Lie group integrators -- basics, new developments and applications
We give a short and elementary introduction to Lie group methods. A selection of applications of Lie group integrators are discussed. Finally, a family of symplectic integrators on cotangent bundles of Lie groups is presented and the notion of discrete ...
