Una nueva expresión acerca del producto de convolución de la derivada de orden k de la delta de Dirac en IxI2-M2

open access: yesNexo, 2010
In this paper, we obtain a expansion in series (type Taylor) of distribution (formula) and give a new expression for the convolution product of (formula) Other expressions of that product appear in ([5]).

Diagnostic Use of Testing for Novel Murine Autoantibodies for Sjögren Disease in the Rheumatology Outpatient Setting

open access: yesArthritis Care &Research, EarlyView.
Objective The goal was to assess the diagnostic performance of three novel autoantibodies (NA) for Sjögren disease (SjD) by comparing NA prevalence in patients with SjD, other autoimmune rheumatic diseases (ARDs), nonspecific chronic sialadenitis (CS), and controls.

Note on the Numerical Solutions of the General Matrix Convolution Equations by Using the Iterative Methods and Box Convolution Product

open access: yesAbstract and Applied Analysis, 2010
We define the so-called box convolution product and study their properties in order to present the approximate solutions for the general coupled matrix convolution equations by using iterative methods.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

The quantum convolution product

open access: yesJournal of Physics: Conference Series
Abstract In classical statistical mechanics, physical states (probability measures) are embedded in the Banach algebra of complex Borel measures on phase space, where the algebra product is realized by convolution. Convolution is state-preserving; namely, the convolution of two classical states is a state too.

On Caputo $k$ -Fractional Derivatives and Associated Inequalities

open access: yesIEEE Access, 2019
This paper studies the k-fractional analogue of the Caputo fractional derivatives, their properties, and applications. A convolution of two functions instead of the product is analyzed by means of Caputo k-fractional derivatives.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

PRODUCT AND CONVOLUTION OF CERTAIN UNIVALENT FUNCTIONS

open access: yesHonam Mathematical Journal, 2016
Summary: For \(f_i\) belonging to various subclasses of univalent functions, we investigate the product given by \(h(z)=z\prod_{i=1}^n (f_i(z)/z)^{\gamma_i}\). The largest radius \(\rho\) is determined such that \(h(\rho z)/\rho\) is starlike of order \(\beta\), \(0\leq ...
