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…
