Features of Oscillations in Adiabatic Oscillators with Delay

Моделирование и анализ информационных систем, 2013
In this paper, we describe the features of oscillations in adiabatic oscillators when the delay is introduced into the equation. We give a short description of the method of asymptotic integration of one class of linear delay differential systems in the ...

Averaging Methods for Second-Order Differential Equations and Their Application for Impact Systems

Mathematics, 2020
In this paper, we discuss the averaging method for periodic systems of second order and the behavior of solutions that intersect a hyperplane. We prove an averaging theorem for impact systems.

Finding the Optimal Multimodel Averaging Method for Global Hydrological Simulations

Remote Sensing, 2021
Global gridded precipitations have been extensively considered as the input of hydrological models for runoff simulations around the world. However, the limitations of hydrologic models and the inaccuracies of the precipitation datasets could result in ...

Phase stable swept-source optical coherence tomography with active mode-locking laser for contrast enhancements of retinal angiography

Scientific Reports, 2021
Swept-source optical coherence tomography (SS-OCT) is an attractive high-speed imaging technique for retinal angiography. However, conventional swept lasers vary the cavity length of the laser mechanically to tune the output wavelength. This causes sweep-

An extraction of cycle-to-cycle variation of in-cylinder flow using temporal / spatial averaging and a proposal of variable sized spatial filtering

Nihon Kikai Gakkai ronbunshu, 2019
Cycle-to-cycle variation (CCV) of in-cylinder flow occurs in internal combustion engines. It is necessary to analyze CCV of flow to separate averaged-flow (as low frequency / low wave number) from turbulence (as high frequency / high wave number ...
