A Probabilistic Approach to Robust Optimal Experiment Design with Chance Constraints [PDF]
Accurate estimation of parameters is paramount in developing high-fidelity models for complex dynamical systems. Model-based optimal experiment design (OED) approaches enable systematic design of dynamic experiments to generate input-output data sets ...

Parametrized systems of generalized polynomial equations: first applications to fewnomials
We consider positive solutions to parametrized systems of generalized polynomial equations (with real exponents and positive parameters). By a fundamental result obtained in parallel work, polynomial systems are determined by geometric objects, rather than matrices: a polytope $P$ (arising from the coefficient matrix) and two subspaces representing ...

New results on the generalized frequency response functions of nonlinear volterra systems described by NARX model [PDF]
In order that the nth-order Generalized Frequency Response Function (GFRF) for nonlinear systems described by a NARX model can be directly written into a more straightforward and meaningful form in terms of the first order GFRF and model parameters, the ...

This work considers parametric systems of polynomial equalities and inequalities, the positive dimensional semialgebraic sets defined by them and how these depend on the values of the parameters. In particular, it focuses on the number of connected components that the semialgebraic set has for a given point in parameter space. It proposes algorithms to,

Comprehensive Border Bases for Zero Dimensional Parametric Polynomial Ideals [PDF]
In this paper, we extend the idea of comprehensive Gr\"{o}bner bases given by Weispfenning (1992) to border bases for zero dimensional parametric polynomial ideals.

Robustness Analysis and Optimally Robust Control Design via Sum-of-Squares [PDF]
A control analysis and design framework is proposed for systems subject to parametric uncertainty. The underlying strategies are based on sum-of-squares (SOS) polynomial analysis and nonlinear optimization to design an optimally robust controller.

Feynman integrals as A-hypergeometric functions
We show that the Lee-Pomeransky parametric representation of Feynman integrals can be understood as a solution of a certain Gel’fand-Kapranov-Zelevinsky (GKZ) system.
