Radar matched filtering using the fractional fourier transform [PDF]
, 2010 -A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...

On the restriction of the Fourier transform to polynomial curves [PDF]
, 2007 We prove a Fourier restriction theorem on curves parametrised by the mapping P(t) = (P1(t),..., Pn(t)), where each of the P1,..., Pn is a real-valued polynomial and t belongs to an interval on which each of the P1,..., Pn "resembles" a ...

MODELING OF MEMBRANE SURFACE STATE UNDER POINT IMPACT [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2020 Subject of Research. We consider the problem of finding an analytical solution to a mathematical model and computergenerated simulation of the concentrated mechanical stress impact at a given point of a loaded elastic body. An adequate mathematical model

On the question of optimization of the oil slick biodestruction in the bodies of water
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 We propose the system of nonlinear partial differential equations of parabolic type that describes the processes of oil pollution of water surface and bacterial degradation of this contamination. Problem of the parametric optimization of the acceleration

Mixed problem for the singular partial differential equation of parabolic type
Karpatsʹkì Matematičnì Publìkacìï, 2018 The scheme for solving of a mixed problem is proposed for a differential equation \[a(x)\frac{\partial T}{\partial \tau}= \frac{\partial}{\partial x} \left(c(x)\frac{\partial T}{\partial x}\right) -g(x)\, T\] with coefficients $a(x)$, $g(x)$ that are the
