An Algorithm for Minimization of Boolean Functions in the Class of Toffoli Reversible Logic Circuits [PDF]

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
In this paper, the problem of Boolean function's representation by the reversible circuits constructed of the Toffoli gates is considered. Interest in this problem is connected with actual studies of the possibility for realization of "cold" computations.

A Micro Absolute Distance Measurement Method Based on Dispersion Compensated Polarized Low-Coherence Interferometry

open access: yesSensors, 2020
Micro absolute distance measurement (MADM) is widely used in industrial and military fields. To achieve high accuracy and frequency response, a polarized low-coherence interferometry (PLCI)-based method for MADM is proposed.

Evaluation of Multi-Incidence Angle Polarimetric Gaofen-3 SAR Wave Mode Data for Significant Wave Height Retrieval

open access: yesRemote Sensing, 2022
Significant wave height (SWH) is one of the most important descriptors for ocean wave fields. The polynomial regression (PolR) and Gaussian process regression (GPR) models are implemented to explore the effects of polarization and incidence angles on the

On the nonexistence of certain curves of genus two [PDF]

open access: yes, 2002
We prove that if q is a power of an odd prime then there is no genus-2 curve over F_q whose Jacobian has characteristic polynomial of Frobenius equal to x^4 + (2-2q)x^2 + q^2.

On polar Legendre polynomials

open access: yesRocky Mountain Journal of Mathematics, 2010
We introduce a new class of polynomials $\{P_{n}\}$, that we call polar Legendre polynomials, they appear as solutions of an inverse Gauss problem of equilibrium position of a field of forces with $n+1$ unit masses. We study algebraic, differential and asymptotic properties of this class of polynomials, that are simultaneously orthogonal with respect ...
