Verifying of reciprocal relations for nonlinear quadripole in unsteady mode

open access: yesResults in Physics, 2017
This paper deals with experimental verification of reciprocal relations of nonlinear quadripole for unsteady mode in external magnetic field. We find out transients of measured voltages in the quadripole after current switch.

Fiber-optic filter fluorometer for emission detection of Protoporphyrin IX and its direct precursors – A preliminary study for improved Photodynamic Therapy applications

open access: yesResults in Physics, 2018
In this work we present first results of a laboratory manufactured filter-fluorometer to study differences in intensity and position of the main peaks of three porphyrins that appear during the Heme-Synthesis. Porphyrins play a major role in Photodynamic

Recent improvements in Hurricane Imaging Radiometer’s brightness temperature image reconstruction

open access: yesResults in Physics, 2017
NASA MSFCs airborne Hurricane Imaging Radiometer (HIRAD) uses interferometric aperture synthesis to produce high resolution wide swath images of scene brightness temperature (Tb) distribution at four discrete C-band microwave frequencies (4.0, 5.0, 6.0 ...

About a family of C2 splines with one free generating function [PDF]

open access: yesComputer Science Journal of Moldova, 2005
The problem of interpolation of discrete set of data on the interval [a, b] representing the function f is investigated. A family of C*C splines with one free generating function is introduced in order to solve this problem.

Adsorption of binary polymer mixtures with different topology on a wall

open access: yesResults in Physics, 2019
We consider a binary mixture of two polymers with different architecture, consisting of linear and cyclic chains. We study this system by performing extensive molecular dynamics computer simulations of bead-spring models, which possess the open-chain and

Coupling efficiency of a partially coherent collimating laser from turbulent biological tissue to fiber

open access: yesResults in Physics, 2019
We propose a model of the fiber coupling efficiency for a partially coherent collimating laser beam propagating through turbulent biological tissue to fiber.

Shepard operator of least squares thin-plate spline type

open access: yes, 2021
We obtain some new Shepard type operators based on the classical, the modified Shepard methods and the least squares thin-plate spline function. Given some sets of points, we compute some representative subsets of knot points following an algorithm ...

Strong inequalities for the iterated Boolean sums of Bernstein operators: Dedicated to Professor Heiner Gonska on the occasion of his 70th anniversary.

open access: yes, 2022
In this paper we investigate the approximation properties for the iterated Boolean sums of Bernstein operators. The approximation behaviour of those operators is presented by the so-called strong inequalities. Moreover, such strong inequalities are valid

The combined Shepard operator of inverse quadratic and inverse multiquadric type

open access: yes, 2022
Starting with the classical, the modified and the iterative Shepard methods, we construct some new Shepard type operators, using the inverse qua- dratic and the inverse multiquadric radial basis functions.

Constrained visualisation using Shepard-Bernoulli interpolation operator

open access: yes, 2020
We consider Shepard-Bernoulli operator in order to solve a problem of interpolation of scattered data that is constrained to preserve positivity, using the technique described by K.W. Brodlie, M.R. Asim and K. Unsworth (2005). We also give some numerical
