Cybersecurity is a process that involves prevention, detection and reaction or response, and must include a learning element for the continuous improvement of the process itself. This study aims to determine the most used models of cybersecurity maturity. For this, a systematic review of studies published from 2012 to 2017 was carried out. Finding 201 articles that mention the different maturity models...
This paper presents a method for computing the total semiconductor power losses within different bidirectional switches aimed to build AC/AC converters (matrix converters). Bidirectional switches built with different power device technologies are characterized in static as well as in dynamic operation in order to extract their key parameters and thus, model their behavior in the conduction and switching...
This paper introduces a software tool for designing customized fuzzy color spaces able to fill the semantic gap between the color representation in computers and the subjective human perception. Fuzzy colors allow introducing semantics in the description of color by using linguistic labels, taking into account the fuzzy boundaries between the representation of color terms. JFCS Tool is based on an...
We present a GaSb-VCSEL concept using SOI-based HCGs as highly reflective mirrors. The optical properties of two different grating designs are simulated using RCWA. These gratings show strong and broadband reflection around 2.3 µm.
In this paper we introduce formal definitions of the concepts of fuzzy color and fuzzy color space. We present an approach to the automatic design of customized fuzzy color spaces on the basis of a collection of crisp colors, each crisp color being fully representative of a certain color term. The approach works on any euclidean crisp space and is based on obtaining a Voronoi diagram having the aforementioned...
The metal–insulator transition observed in the In/Si(111)-4×1 reconstruction is studied by means of ab initio calculations of a simplified model of the surface. Different surface bands are identified and classified according to their origin and their response to several structural distortions. We support the, recently proposed [C. González, J. Ortega, F. Flores, New J. Phys. 7 (2005) 100], combination...
