Minimal numerical differentiation formulas [PDF]
Numerische Mathematik, 2018 We investigate numerical differentiation formulas on irregular centers in two or more variables that are exact for polynomials of a given order and minimize an absolute seminorm of the weight vector. Error bounds are given in terms of a growth function that carries the information about the geometry of the centers.

Interpolation on the Bakhvalov mesh in the presence of an exponential boundary layer
Учёные записки Казанского университета: Серия Физико-математические науки, 2019 Interpolation of the function of one variable with large gradients in the region of the exponential boundary layer was studied. The interpolated function corresponds to solution of a boundary value problem for an ordinary differential equation of the ...

Innovative Demodulation Scheme for Coherent Detectors in CMB Experiments
, 2012 We propose an innovative demodulation scheme for coherent detectors used in cosmic microwave background polarization experiments. Removal of non-white noise, e.g., narrow-band noise, in detectors is one of the key requirements for the experiments.

An effective spectral collocation method for the direct solution of high-order ODEs [PDF]
, 2006 This paper reports a new Chebyshev spectral collocation method for directly solving high-order ordinary differential equations (ODEs). The construction of the Chebyshev approximations is based on integration rather than conventional differentiation. This
