Methodology for Maintaining the Dynamic Characteristics of Passenger Cars

open access: yesCommunications, 2023
The work presents the results of a statistical analysis of random processes of the coefficient of vertical dynamics of a passenger car variation. To determine the dynamic performance of cars the tests were running on the tracks of JSC "Ukrzaliznytsia ...

Inverting the Angular Correlation Function [PDF]

open access: yes, 1999
The two point angular correlation function is an excellent measure of structure in the universe. To extract from it the three dimensional power spectrum, one must invert Limber's Equation.

Correlation functions on Cylinders

open access: yesPhysical Review Letters, 1994
We have obtained the complete finite-size structure of energy-density correlation functions at all temperatures defined for two-dimensional Ising models on cylindrical lattices, extending the original results of Hecht. This reveals novel structure in terms of winding numbers and confirms predictions from conformal invariance theory to leading order.

USE OF TRIANGULAR MODELS OF NON-STATIONARY PROCESSES IN MODELING VARIABILITY OF HEART RHYTHM

open access: yesСучасний стан наукових досліджень та технологій в промисловості, 2019
The subject matter is a mathematical model describing the process of heart rhythm variability, which is based on the use of triangular models of non-stationary random processes in the Hilbert space.

Incoherent Neutron Scattering and Terahertz Time-Domain Spectroscopy on Protein and Hydration Water

open access: yesLife, 2023
Incoherent inelastic and quasi-elastic neutron scattering (INS) and terahertz time-domain spectroscopy (THz-TDS) are spectroscopy methods that directly detect molecular dynamics, with an overlap in the measured energy regions of each method.

An Innovative Structural Dynamic Identification Procedure Combining Time Domain OMA Technique and GA

open access: yesBuildings, 2022
In this paper an innovative and simple Operational Modal Analysis (OMA) method for structural dynamic identification is proposed. It combines the recently introduced Time Domain–Analytical Signal Method (TD–ASM) with the Genetic Algorithm (GA ...

The correlation function of radio sources [PDF]

open access: yes, 1996
We investigate the large-scale clustering of radio sources in the Green Bank and Parkes-MIT-NRAO 4.85 GHz surveys by measuring the angular two-point correlation function w(\theta).

ANALYTICAL MODEL OF A DIFFERENTIAL METHOD FOR RECEIVING AND PROCESSING SIGNALS OF THE INFRARED RANGE OF WAVELENGTHS

open access: yesНаучный вестник МГТУ ГА, 2017
One of the classic methods to improve the noise immunity of passive detection of infrared wavelength range (IKSO) is a differential inclusion of pyrocatechol, placed at some distance.
