Ransomware early detection by the analysis of file sharing traffic
(Elsevier, 2018)
Artículo / Artikulua,
Crypto ransomware is a type of malware that locks access to user files by encrypting them and demands a ransom in order to obtain the decryption key. This type of malware has become a serious threat for most enterprises. ...
Steering surface plasmons with a graded index dielectric medium
(IOP Publishing, 2018)
Artículo / Artikulua,
The arbitrary control of surface plasmon (SP) propagation has become an intense research topic for several decades. This is due to the fact that they can be used in a variety of fields such as optical trapping, nanoantennas ...
Parameter-independent control for battery chargers based on virtual impedance emulation
(IEEE, 2018)
Artículo / Artikulua,
An effective battery voltage regulation is fundamental to extend battery lifetime and to avoid overvoltage. However, the design of this regulation is complicated due to the wide battery impedance range, which, when dealing ...
New measures for comparing matrices and their application to image processing
(Elsevier, 2018)
Artículo / Artikulua,
In this work we present the class of matrix resemblance functions, i.e., functions that measure
the difference between two matrices. We present two construction methods and study the properties
that matrix resemblance ...
Implementation and operational analysis of an interactive intensive care unit within a smart health context
(MDPI, 2018)
info:eu-repo/semantics/article,
In the context of hospital management and operation, Intensive Care Units (ICU) are
one of the most challenging in terms of time responsiveness and criticality, in which adequate
resource management and signal processing ...
Methodology for sizing stand-alone hybrid systems: a case study of a traffic control system
(Elsevier, 2018)
Artículo / Artikulua,
This paper proposes a methodology for sizing stand-alone hybrid photovoltaic-wind power generation systems. This methodology makes it possible to optimise the overall performance of the stand-alone system components, based ...
Cloud tomography applied to sky images: a virtual testbed
(Elsevier, 2018)
info:eu-repo/semantics/article,
Two tomographic techniques are applied to two simulated sets of sky images with different cloud fraction. The Algebraic Reconstruction Technique (ART) is applied to optical depth maps from sky images to reconstruct 3-D ...
Gas detection using LMR-based optical fiber sensors
(MDPI, 2018)
Artículo / Artikulua,
This work presents a first approach to the utilization of Lossy Mode Resonance (LMR)
based optical fiber sensors for gas detection. The optical sensor is based on a SnO2 thin-film
fabricated onto the core of cladding ...
Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
(IEEE, 2018)
Artículo / Artikulua,
Two phenomena for enhancing the sensitivity of longperiod
fiber gratings are combined toward an increase of the sensitivity
to strain of this type of devices: the dispersion turning point
(DTP) and the cladding diameter ...
Nanofabrication of phase-shifted Bragg gratings on the end facet of multimode fiber towards development of optical filters and sensors
(Elsevier, 2018)
Artículo / Artikulua,
This work describes the process of nanofabrication of phase-shifted Bragg gratings on the end facet of a
multimode optical fiber with a pulsed DC sputtering system based on a single target. Several structures
have been ...
