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 ...
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 ...
Kinematic design of a new four degree-of-freedom parallel robot for knee rehabilitation
(ASME, 2018)
Artículo / Artikulua,
Rehabilitation robots are increasingly being developed in order to be used by injured people to perform exercise and training. As these exercises do not need wide range movements, some parallel robots with lower mobility ...
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 ...
Convolution lattices
(Elsevier, 2018)
Artículo / Artikulua,
We propose two convolution operations on the set of functions between two bounded lattices and investigate the algebraic structure they constitute, in particular the lattice laws they satisfy. Each of these laws requires ...
Multivalued contexts associated with criteria
(Taylor & Francis, 2018)
Artículo / Artikulua,
We are interested in the study of L-fuzzy contexts taking into account different criteria. These contexts arise when we want to analyze the relationship between objects and attributes from different points of view. ...
Pulse coding linearization for Brillouin optical time-domain analysis sensors
(Optical Society of America, 2018)
Artículo / Artikulua,
We introduce a simple method to extend the performance of pulse coding techniques in their application to Brillouin optical time-domain analysis sensors (BOTDA). It is based on applying a simple logarithmic processing on ...
THz sensing with anomalous extraordinary optical transmission hole arrays
(MDPI, 2018)
Artículo / Artikulua,
Subwavelength hole array (HA) metasurfaces support the so-called extraordinary optical transmission (EOT) resonance that has already been exploited for sensing. In this work, we demonstrate the superior performance of a ...
Comparison between capacitive and microstructured optical fiber soil moisture sensors
(MDPI, 2018)
Artículo / Artikulua,
Soil moisture content has always been an important parameter to control because it is a
deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection.
In this work, a discrete sensor ...
