On the Number of Zeros of Abelian Integrals: A Constructive Solution of the Infinitesimal Hilbert Sixteenth Problem [PDF]
We prove that the number of limit cycles generated by a small non-conservative perturbation of a Hamiltonian polynomial vector field on the plane, is bounded by a double exponential of the degree of the fields.

Positive Solutions of Systems of Signed Parametric Polynomial Inequalities [PDF]
We consider systems of strict multivariate polynomial inequalities over thereals. All polynomial coefficients are parameters ranging over the reals, wherefor each coefficient we prescribe its sign. We are interested in the existenceof positive real solutions of our system for all choices of coefficientssubject to our sign conditions. We give a decision

Tabular Open Circuit Voltage Modelling of Li-Ion Batteries for Robust SOC Estimation
Battery management systems depend on open circuit voltage (OCV) characterization for state of charge (SOC) estimation in real time. The traditional approach to OCV-SOC characterization involves collecting OCV-SOC data from sample battery cells and then ...

Total Degree Formula for the Generic Offset to a Parametric Surface [PDF]
We provide a resultant-based formula for the total degree w.r.t. the spatial variables of the generic offset to a parametric surface. The parametrization of the surface is not assumed to be proper.Comment: Preprint of an article to be published at the ...

Hierarchical Comprehensive Triangular Decomposition
The concept of comprehensive triangular decomposition (CTD) was first introduced by Chen et al. in their CASC'2007 paper and could be viewed as an analogue of comprehensive Grobner systems for parametric polynomial systems.

Instantaneous identification of Bouc-Wen-type hysteretic systems from seismic response data [PDF]
This paper presents a technique for identification of non-linear hysteretic systems subjected to non-stationary loading. In the numerical simulations, a Bouc-Wen model was chosen for its ability to represent the properties of a wide class of real ...

Approximation of high-dimensional parametric PDEs [PDF]
Parametrized families of PDEs arise in various contexts such as inverse problems, control and optimization, risk assessment, and uncertainty quantification. In most of these applications, the number of parameters is large or perhaps even infinite.
