On the kernel of the Stieltjes derivative and the space of bounded Stieltjes-differentiable functions

Francisco J. Fernández, Ignacio Márquez Albés, F. Adrián F. Tojo +1

We investigate the existence and uniqueness of solutions to first-order Stieltjes differential problems, focusing on the role of the Stieltjes derivative and its kernel. Unlike the…

Digital twin with automatic disturbance detection for real-time optimization of a semi-autogenous grinding (SAG) mill

Paulina Quintanilla, Francisco Fernández, Cristobal Mancilla +3

This work describes the development and validation of a digital twin for a semi-autogenous grinding (SAG) mill controlled by an expert system. The digital twin consists of three mo…

Penning-trap eigenfrequency measurements with optical radiofrequency detectors

Joaquín Berrocal, Alejandro Hernández, Íñigo Arrazola +5

We use an electric-dipole laser-driven transition to precisely measure the cyclotron-frequency ratios of the pairs Ca-Ca, Ca-Ca and $^{4…

Stieltjes analytic functions and higher order linear differential equations

Víctor Cora, F. Javier Fernández, F. Adrián F. Tojo

In this work we develop a theory of Stieltjes-analytic functions. We first define the Stieltjes monomials and polynomials and we study them exhaustively. Then, we introduce the Sti…

Pile-up corrections in laser-driven pulsed x-ray sources

Guillermo Hernández, Francisco Fernández

A formalism for treating the pile-up produced in solid-state detectors by laser-driven pulsed x-ray sources has been developed. It allows the direct use of x-ray spectroscopy witho…
