On the constrained Chebyshev approximation problem on ellipses [PDF]

Constrained Chebyshev approximation problems of the type with minimum (p is an element of Pi(sub n):p(c)=1) and maximum (z is an element of E) with /p(z)/ are considered. Here Pi(sub n) denotes the set of all complex polynomials of degree at most n, E is

An analytical approximation of the evolution of the primordial curvature perturbation in the ultraslow-roll inflation: an extended study

European Physical Journal C: Particles and Fields
Cosmic inflation can enter an ultraslow-roll (USR) stage, if there is a plateau on the inflaton potential. During this stage, the primordial curvature perturbation $${{\mathscr {R}}}_k$$ R k and its power spectrum $${{\mathscr {P}}}_{{\mathscr {R}}}$$ P ...

Polynomial approximation, local polynomial convexity, and degenerate CR singularities -- II

, 2011
We provide some conditions for the graph of a Hoelder-continuous function on \bar{D}, where \bar{D} is a closed disc in the complex plane, to be polynomially convex.

The Relationship Between the Magnetometer Data Derived GIC Index and Measured GIC in High Voltage Transformers in Australia

Space Weather
Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks.

A fully digital model for Kalman filters

, 2010
The Kalman filter is a mathematical method, whose purpose is to process noisy measurements in order to obtain an estimate of some relevant parameters of a system.
