Development of the Method of Averaging in Clifford Geometric Algebras
Mathematics, 2023 We develop the method of averaging in Clifford (geometric) algebras suggested by the author in previous papers. We consider operators constructed using two different sets of anticommuting elements of real or complexified Clifford algebras.

Investigation of Wind Data Resolution for Small Wind Turbine Performance Study
Journal of Energy in Southern Africa, 2022 Small wind turbine sites, in general, use a 0.5Hz sampling interval and a 10-minute averaging interval for a feasibility study or turbine testing. Studies have established that the calculated performance variation of small wind turbines when averaging

Averaging for ordinary differential equations perturbed by a small parameter [PDF]
Mathematica Bohemica, 2016 In this paper, we prove and discuss averaging results for ordinary differential equations perturbed by a small parameter. The conditions we assume on the right-hand sides of the equations under which our averaging results are stated are more general than

Asymptotics for Solutions of Harmonic Oscillator with Integral Perturbation
Моделирование и анализ информационных систем, 2017 We construct the asymptotics for solutions of a harmonic oscillator with integral perturbation when the independent variable tends to infinity. The specific feature of the considered integral perturbation is an oscillatory decreasing character of its ...

Substantiation of averaging the content of mined ores with account of their readiness for mining [PDF]
E3S Web of Conferences, 2020 Paper demonstrates the importance of substantiating the reserves volumes ready for mining in extraction units, in accordance with the mine output capacity, averaging mode and reducing the variation in the mined product quality.

The method of residual-based bootstrap averaging of the forecast ensemble
Financial Innovation, 2023 This paper presents an optimization approach—residual-based bootstrap averaging (RBBA)—for different types of forecast ensembles. Unlike traditional residual-mean-square-error-based ensemble forecast averaging approaches, the RBBA method attempts to find

Electronic Journal of Qualitative Theory of Differential Equations, 2016 In this paper we study the asymptotic integration problem in the neighborhood of infinity for a certain class of linear functional differential systems. We propose a method for construction of the asymptotics of solutions in the critical case.

Asymptotic Integration of a Certain Second-Order Linear Delay Differential Equation
Моделирование и анализ информационных систем, 2016 We construct some asymptotic formulas for solutions of a certain linear second-order delay differential equation when the independent variable tends to infinity. Two features concerning the considered equation should be emphasized. First, the coefficient

Parametric Resonance in a Time-Dependent Harmonic Oscillator
Моделирование и анализ информационных систем, 2013 In this paper, we study the phenomenon of appearance of new resonances in a timedependent harmonic oscillator under an oscillatory decreasing force. The studied equation belongs to the class of adiabatic oscillators and arises in connection with the ...
