A Study on COVID-19 Incidence in Europe through Two SEIR Epidemic Models Which Consider Mixed Contagions from Asymptomatic and Symptomatic Individuals
(MDPI, 2021-07-06)
The impact of the SARS-CoV-2 (COVID-19) on the world has been partially controlled through different measures of social isolation and prophylaxis. Two new SEIR (Susceptible-Exposed-Infected-Recovered) models are proposed ...
On the Properties of a Class of Impulsive Competition Beverton–Holt Equations
(MDPI, 2021-09-28)
This paper is devoted to a type of combined impulsive discrete Beverton–Holt equations in ecology when eventual discontinuities at sampling time instants are considered. Such discontinuities could be interpreted as impulses ...
Design, analysis and implementation of a versatile low level radio frequency system for accelerating cavities

[ES]En esta tesis se describen diversas soluciones analógicas y digitales para realizar sistemas de control LLRF (Radio Frecuencia de Bajo Nivel) para cavidades resonantes de radiofrecuencia de aceleradores de partículas. ...
Complex Formalism of the Linear Beam Dynamics
(IEEE-Institute of Electrical and Electronics Engineers, 2021-03)
It has long been known that the ellipse normally used to model the phase space extension of a beam in linear dynamics may be represented by a complex number which can be interpreted similar to a complex impedance in ...
Design and Manufacturing of accelerator components for use on linacs.
(2017-07-26)
En esta tesis se investiga desde el punto de vista tanto teórico como práctico el uso de cuadrupolos de imanes permanentes (PMQ) para crear las estructuras de focalización dentro de un acelerador basado en tubos de deriva ...
Equivalence between the Existence of Best Proximity Points and Fixed Points for Some Classes of Proximal Contractions
(MDPI, 2022-09-13)
In the year 2014, Almeida et al. introduced a new class of mappings, namely, contractions of Geraghty type. Additionally, in the year 2021, Beg et al. introduced the concept of generalized F-proximal contraction of the ...
Functionalized magnetoelastic resonant platforms for chemical and biological detection purposes
(2018-03-26)
In recent years, research on magnetoelastic materials has focused on their applications as sensors to observe, measure and control different kind of physical, chemical and biological parameters, taking advantage of the ...
Ball Milled Gd Flakes Subjected to Heat Treatments: Structure, Magnetic and Magnetocaloric Properties
(MDPI, 2022-10-23)
Gd flake samples were prepared by conventional ball milling technique starting from rapidly quenched Gd ribbons and followed by vacuum annealing in different conditions. Heat treatments were conducted in a vacuum at selected ...
Generalized Cyclic p-Contractions and p-Contraction Pairs Some Properties of Asymptotic Regularity Best Proximity Points, Fixed Points
(MDPI, 2022-10-26)
This paper studies a general p-contractive condition of a self-mapping T on X, where (X ,d) is either a metric space or a dislocated metric space, which combines the contribution to the upper-bound of d(Tx , Ty), where x ...
Structural and Magnetic Properties of FeNi Films and FeNi-Based Trilayers with Out-of-Plane Magnetization Component
(MDPI, 2022-10-31)
FeNi films of different thickness and FeNi/(Fe, Co)/FeNi trilayers were prepared by magnetron sputtering deposition onto glass substrates. The permalloy films had a columnar microstructure. The detailed analysis of the ...
