Lucas polynomials semi-analytic solution for fractional multi-term initial value problems
Advances in Difference Equations, 2019 Herein, we use the generalized Lucas polynomials to find an approximate numerical solution for fractional initial value problems (FIVPs). The method depends on the operational matrices for fractional differentiation and integration of generalized Lucas ...

Towards data‐driven predictive maintenance for vacuum ion pumps at European XFEL
Journal of Synchrotron Radiation, EarlyView.This paper presents a machine‐learning‐based approach for early fault detection in vacuum ion pumps at the European XFEL by analyzing pressure data to detect fault precursors. The developed method enables predictive maintenance, reducing unplanned downtime and improving operational reliability.Large‐scale scientific facilities, such as the European ...

On a new family of the generalized gauss k-pell-lucas numbers and their polynomials
, 2022 In this paper, we generalize the known Gauss Pell-Lucas numbers, and call such numbers as the generalized Gauss k-Pell-Lucas numbers. We obtain relations between the family of the generalized Gauss k-Pell-Lucas numbers and the known Gauss Pell-Lucas ...

Estimating the Common Output Cycle in Australia
Australian Economic Review, EarlyView.ABSTRACT Background/Objective This study develops a statistical measure of Australia's common output cycle and investigates the extent to which cyclical fluctuations are shared across industries. It also evaluates whether the common output cycle provides useful information for forecasting inflation.
