Subclasses of Noshiro-Type Starlike Harmonic Functions Involving q-Srivastava–Attiya Operator

open access: yesMathematics, 2023
In this paper, the harmonic function related to the q-Srivastava–Attiya operator is described to introduce a new class of complex harmonic functions that are orientation-preserving and univalent in the open-unit disk. We also cover some important aspects

The harmonic mean p-value for combining dependent tests

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance The widespread use of Bonferroni correction encumbers the scientific process and wastes opportunities for discovery presented by big data, because it discourages exploratory analyses by overpenalizing the total number of statistical tests ...

Capturing Long-Range Dependence and Harmonic Phenomena in 24-Hour Solar Irradiance Forecasting: A Quantile Regression Robustification via Forecasts Combination Approach

open access: yesIEEE Access, 2020
The global horizontal irradiance data recorded at the earth's horizontal surface is a mixture of deterministic (extra-terrestrially) and stochastic components due to the ever-changing atmospheric conditions. The Box-Jenkins short memory stochastic models

Damper Winding for Noise and Vibration Reduction of a Permanent Magnet Synchronous Machine

open access: yesSensors, 2022
In this paper, a passive method for the noise reduction of the PMSM (Permanent Magnet Synchronous Machine) is presented. The principle is to add an auxiliary three-phase winding into the same slots as the initial stator winding, short-circuited via three

Multi-Objective Artificial Bee Colony Algorithm with Minimum Manhattan Distance for Passive Power Filter Optimization Problems

open access: yesMathematics, 2021
Passive power filters (PPFs) are most effective in mitigating harmonic pollution from power systems; however, the design of PPFs involves several objectives, which makes them a complex multiple-objective optimization problem. This study proposes a method

On an atomic decomposition in Banach spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
An atomic decomposition is considered in Banach space.  A method for constructing an atomic decomposition of Banach  space, starting with atomic decomposition of  subspaces  is presented. Some relations between them are established.
