Approximation of functions by a class of Durrmeyer–Stancu type operators which includes Euler’s beta function

open access: yesAdvances in Difference Equations, 2021
In this work, we construct the genuine Durrmeyer–Stancu type operators depending on parameter α in [ 0 , 1 ] $[0,1]$ as well as ρ > 0 $\rho >0$ and study some useful basic properties of the operators.

Development of microclimate in the New Holland T6.165 tractor

open access: yesResearch in Agricultural Engineering, 2023
A number of stimuli lead to what is termed "seasonal fatigue", where the only firm interconnection is the fact that this form of fatigue only occurs during a certain period of the season.

Black hole complementarity from microstate models: a study of information replication and the encoding in the black hole interior

open access: yesJournal of High Energy Physics, 2023
We study how the black hole complementarity principle can emerge from quantum gravitational dynamics within a local semiclassical approximation. Further developing and then simplifying a microstate model based on the fragmentation instability of a near ...

Correlation between Individual Characteristics, Work Monotony, and Mental Workload with Work Stress

open access: yesThe Indonesian Journal of Occupational Safety and Health, 2023
Introduction: Work stress is the inability of a worker to face job demands, leading to discomfort while working. Work stress can be caused by many factors, among them work monotony, excessive workload, and individual characteristics. This study's aim was

Psi_B-energy operator and cross-power spectral density [PDF]

open access: yes, 2014
In this paper we consider the hermitian extension of the cross-Psi_B-energy operator that we will denote by Psi_H. In addition, cross energy terms are formalized through multivariate signals representation.

Operator valued Dirichlet problem in the plane [PDF]

open access: yes, 2012
We consider an operator valued Dirichlet problem for harmonic mappings and prove the existence of a Perron-like solution. To formulate the Perron’s construction we make use of Olson’s notion of spectral order.
