A biased-randomized learnheuristic for solving the team orienteering problem with dynamic rewards
In this paper we discuss the team orienteering problem (TOP) with dynamic inputs. In the static version of the TOP, a fixed reward is obtained after visiting each node. Hence, given a limited fleet of vehicles and a threshold ... -
Evolution of L-fuzzy contexts associated with criteria
This paper will delve deeper into the general study of the L-fuzzy contexts associated with criteria analyzing situations with a known evolution over time. These criteria may be independent or dependent on each other. We ... -
A strategic multistage tactical two-stage stochastic optimization model for the airline fleet management problem
This work proposes stochastic optimization for the airline fleet management problem, considering uncertainty in the demand, operational costs, and fares. In particular, a multistage tree is proposed, compounded of strategic ... -
High-speed analysis of SMB2 file sharing traffic without TCP stream reconstruction
This paper presents a file sharing traffic analysis methodology for Server Message Block (SMB), a common protocol in the corporate environment. The design is focused on improving the traffic analysis rate that can be ... -
Energy harvesting approaches in IoT scenarios with very low ambient energy
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2019) Contribución a congreso / Biltzarrerako ekarpenaThe feasibility of multi-source energy harvesting in Internet of Things (IoT) scenarios with low and intermittent ambient energy is addressed.

Micro-drilled optical fiber for enhanced laser strain sensors
In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber ... -
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ... -
Structural health monitoring of solar trackers using distributed fiber optic sensors
We demonstrate the application of a novel type of distributed fiber optic sensors (DFOSs) to dynamically monitor the effects of wind on solar tracker structures used in photovoltaic power stations. This DFOS is based on ... -
DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input ... -
Single feedback regulation of the AC voltage for high-power inverters under stand-alone operation
Energy-storage inverters under stand-alone operation must control the output voltage. However, existing methods for instantaneous voltage regulation are not suitable for high-power inverters due to their limited sampling ... -
Latest research on long-range Brillouin distributed sensing
We review the latest developments in long-range Brillouin optical time-domain analysis sensors. The factors that impair the performance of these sensors, particularly in terms of their distance range, are discussed together ... -
Analysis of the main battery characterization techniques and experimental comparison of commercial 18650 Li-ion cells
Over the coming years, major growth in the use of Li-ion batteries is expected, both in electric mobility as well as in stationary applications, be it in self-consumption systems and micro grids or in large renewable power ... -
Characterization of 3D-printed choke horn antenna for 5G backhaul applications
The 200 and 320 GHz frequency band constitutes an interesting window with approximately constant attenuation, which could potentially have applications in the area of ultrahigh-capacity wireless links. The user's demand ... -
Do we still need fuzzy classifiers for Small Data in the Era of Big Data?
The Era of Big Data has forced researchers to explore new distributed solutions for building fuzzy classifiers, which often introduce approximation errors or make strong assumptions to reduce computational and memory ... -
Characterization and capacity dispersion of lithium-ion second-life batteries from electric vehicles
Nowadays, electric vehicle batteries reutilization is considered such as a feasible alternative to recycling, as it allows to benefit from their remaining energy and to enlarge their lifetime. Stationary applications as ... -

Super-resolution for Sentinel-2 images
(International Society for Photogrammetry and Remote Sensing, 2019) Contribución a congreso / Biltzarrerako ekarpenaObtaining Sentinel-2 imagery of higher spatial resolution than the native bands while ensuring that output imagery preserves the original radiometry has become a key issue since the deployment of Sentinel-2 satellites. ... -
Description and properties of curve-based monotone functions
Curve-based monotonicity is one of the lately introduced relaxations of monotonicity. As directional monotonicity regards monotonicity along fixed rays, which are given by real vectors, curve-based monotonicity studies the ... -
