The error accumulation in the conjugate gradient method for degenerate problem
Anton Ryabtsev
In this paper, we consider the conjugate gradient method for solving the problem of minimizing a quadratic function with additive noise in the gradient. Three concepts of noise wer…

Fluid flow vorticity measurement using laser beams with orbital angular momentum
A. Ryabtsev, S. Pouya, A. Safaripour +2
We report on the direct measurements of fluid flow vorticity using a spatially shaped beam with a superposition of Laguerre-Gaussian modes that reports on the rotational Doppler sh…
