¿Cómo afecta la innovación en la satisfacción y la lealtad hacia el establecimiento minorista?

2021

Resumen En el presente estudio, se examinó el concepto de innovación en el sector minorista y se definieron sus relaciones con otras variables, como la satisfacción y la lealtad, tradicionalmente vinculadas con el establecimiento minorista. Para lograr los objetivos planteados, se delimitó un modelo teórico sustentado en la literatura, que se contrastó mediante un estudio empírico utilizando un cuestionario estructurado ad hoc aplicado a una muestra de 510 clientes de establecimientos de alimentación. El análisis de los datos se desarrolló mediante la técnica de regresión por mínimos cuadrados parciales. Los resultados permiten proponer un conjunto de recomendaciones para la gestión, fundam…

Modulador acusto-óptico en amplitud de fibra óptica basado en ondas acústicas de flexión

2014

Se reporta un estudio experimental de la operación de un modulador acusto-óptico (MAO) de fibra óptica basado en la interacción acusto-óptica producida por ondas acústicas de flexión estacionarias. Concentramos nuestra atención en los efectos de reducir el diámetro en la fibra óptica como mecanismo para optimizar la respuesta espectral del MAO. Como caso particular reportamos un modulador de 70 ¹m de diametro con una alta profundidad de modulación (60 %), bajas perdidas por inserción (1.3 dB) y un ancho ancho de banda a 3 dB de 40 nm que opera en el rango de los megahertz. Los resultados obtenidos demuestran que el incluir fibras estrechadas se puede considerar como un grado extra de libert…

La forma de gobierno en la Constitución de Cádiz (reflexiones sobre la configuración de la Jefatura del Estado monárquica)

2012

A partir de las circunstancias históricas de las Cortes de Cádiz y de los precedentes de la monarquía española, el artículo analiza la posición de la Jefatura del Estado monárquica en la Constitución de 1812 caracterizada como una «Monarquía moderada» basada en los principios estructurales de soberanía nacional y división de poderes que determinan la configuración del Rey como poder constituido en la nueva forma de gobierno. La afirmación de la soberanía nacional impregna el conjunto del texto constitucional sin perjuicio de que coexista retóricamente con la antigua legitimidad monárquica. Por otra parte, la división de poderes supone la distinción entre la titularidad de la soberanía y su …

Optimum Design and Performance of an Electron Gun for a Ka-Band TWT

2019

This paper deals with optimum design and development of a thermionic electron gun to meet specified beam requirements within defined electric and geometric constraints for a Ka -band traveling wave tube (TWT) for space applications. The electron gun design is based on the Pierce method and carried out according to the iterative process indicated by Vaughan. The design of a periodic permanent magnet (PPM) beam focusing system for the stability of the beam is also required. A sensitivity analysis, by varying electric parameters and geometric parameters, is presented and taken into account as a fundamental role to the aim of optimizing the design of the Pierce gun. A cathode current value of 5…

Correlative study of structural and optical properties of ZnSe under severe plastic deformation

2019

The effect of plastic deformation on the optical and structural properties of ZnSe crystals has been investigated. The optical properties have been monitored by cathodoluminescence measurements as a function of the deformation degree. Remarkable differences in the defect-related emissions from the most severely deformed areas have been encountered. Deformation of the crystal lattice of ZnSe, associated with slip phenomena, has been studied by means of Electron Backscattered Diffraction and micro-Raman spectroscopy. The relation between the deformation and the optical properties of the ZnSe crystals has been described.

Preparation and Characterization of Nanocrystalline Gadolinium Oxide Powders and Films

2020

Due to its magnetic, electrical, absorption, and emission properties, nanoscale gadolinium oxide is widely used in various fields. In this research, nanocrystalline Gd2O3 powders and films on glass substrates have been produced by the extraction-pyrolytic method. X-ray diffraction analysis revealed the formation of single phase Gd2O3 with cubic crystal structure and the mean crystallite size from 9 to 25 nm in all produced materials. The morphology of samples has been characterized by scanning electron microscopy and transmission electron microscopy.

First Results of Hyperspectral Scene Generation in Preparation of the Chime Imaging Spectrometer Mission

2021

End-To-End mission performance simulators (E2Es) are software tools developed to support satellite mission preparatory activities. For passive remote sensing missions, E2Es generate synthetic scenes simulating the interaction of the solar radiation between the atmosphere and the surface; therefore allowing the estimation of the mission performance before its launch. In this paper, we present the CHIME Scene Generator Module (SGM) as part of CHIME E2Es, with state-of-the-art parallelization and optimization that give a performance allowing to obtain a whole year of daily worldwide Top-Of-Atmosphere radiance images in a matter of hours. The CHIME SGM generates 100x200km hyperspectral scenes w…

Thematic vent opening probability maps and hazard assessment of small-scale pyroclastic density currents in the San Salvador volcanic complex (El Sal…

2021

The San Salvador volcanic complex (El Salvador) and Nejapa-Chiltepe volcanic complex (Nicaragua) have been characterized by a significant variability in eruption style and vent location. Densely inhabited cities are built on them and their surroundings, including the metropolitan areas of San Salvador (∼2.4 million people) and Managua (∼1.4 million people), respectively. In this study we present novel vent opening probability maps for these volcanic complexes, which are based on a multi-model approach that relies on kernel density estimators. In particular, we present thematic vent opening maps, i.e., we consider different hazardous phenomena separately, including lava emission, small-scale…

The Making of the New European Wind Atlas - Part 2: production and evaluation

2020

This is the second of two papers that document the creation of the New European Wind Atlas (NEWA). In Part 1, we described the sensitivity experiments and accompanying evaluation done to arrive at the final mesoscale model setup used to produce the mesoscale wind atlas. In this paper, Part 2, we document how we made the final wind atlas product, covering both the production of the mesoscale climatology generated with the Weather Research and Forecasting (WRF) model and the microscale climatology generated with the Wind Atlas Analysis and Applications Program (WAsP). The paper includes a detailed description of the technical and practical aspects that went into running the mesoscale simulati…
