Stochastic market modeling with Gaussian Quadratures: Do rotations of Stroud's octahedron matter? [PDF]
, 2014 Recently, stochastic applications of large-scale applied simulation models of agricultural markets have become more frequent. However, stochastic modeling with large market models comes with high computational and management costs for data storage ...

Optimal Quadrature-Sparsification for Integral Operator Approximation [PDF]
SIAM Journal on Scientific Computing, 2018 The design of sparse quadratures for the approximation of integral operators related to symmetric positive-semidefinite kernels is addressed. Particular emphasis is placed on the approximation of the main eigenpairs of an initial operator and on the assessment of the approximation accuracy.

Construction for an Approximate Quadrature of the Circle [PDF]
Nature, 1918 THE construction for squaring the circle given by Mr. R. E. Baynes in NATURE for June 6 was described more fully by Mr. T. M. P. Hughes in the issue for April 2, 1914, with a simple extension to the representation of the circumference.

Contact problem of torsion of a multilayer base with elastic connections between layers
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 Torsion of a multilayer base with elastic connections between layers by cylindrical punch with a flat sole was considered. The Hankel integral transform of the first order and the method of the compliance functions were used.
