Compensation of phase-noise in pulse-compression phase-sensitive OTDR sensors
We introduce a technique to compensate the performance impairments due to the laser phase noise in long-range pulse-compression DAS sensors. Experiments demonstrate the use of the longest duration pulse compression waveform ... -
Contributions of artificial intelligence to low resolution renal multiparametric magnetic resonance analysis
Arterial spin labeling (ASL), is a Multiparametric Magnetic Resonance Imaging (MRI) technique used to quantify and evaluate Renal Blood Flow (RBF) and detect perfusion failure by labelling blood water as it flows throughout ... -
Control strategy for a droop-controlled grid-connected DFIG wind turbine
The application of droop control techniques without inner current control loops to doubly-fed induction generator (DFIG) based wind turbines does not allow to provide a stable response at all operating points in terms of ... -
Control strategy for an integrated photovoltaic-battery system
In photovoltaic-battery systems, more attention is usually paid to the MPPT control while the battery management is put aside. This paper proposes two control strategies for an integrated PV-battery system, both of them ... -
Copper oxide coated D-shaped optical fibers for the development of LMR refractometers
Lossy mode resonance (LMR) based refractometers obtained by means of copper oxide thin-films fabricated onto side-polished (D-shaped) are presented in this work. The high refractive index of copper oxide combined with the ... -
Coupling in multilayer devices
Novel design for devices in multilayer stacked is proposed. Split Ring resonators and Complementary Split Ring resonators are used, in microstrip or dual stripline-microstrip configuration to build different devices. A ... -
Critical comparison of energy management algorithms for lithium-ion batteries in renewable power plants
Lithium-ion batteries are gaining importance for a variety of applications due to their price decrease and characteristics improvement. A good energy management strategy is required in order to increase the profitability ... -
DC capacitance reduction in photovoltaic inverters based on PV voltage feed-forward compensation
In the case of photovoltaic (PV) inverters, an adequate input voltage regulation is fundamental to maximize or limit the power. When employing the traditional control, the input capacitance requires to be oversized in order ... -
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 ... -
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 ... -
Design alternatives for a submm-wave Fabry-Perot cavity antenna
This paper discusses different design alternatives for a high gain planar antenna at 240 GHz. The antenna is based on a Fabry-Perot configuration, where two different partial reflection surfaces (PRS) are considered: a ... -
Design of a groove gap waveguide to microstrip inline transition
In this paper the design of an inline transition between microstrip and groove gap waveguide operating at Wband is presented. The transition consists of two sections: a tapered microstrip line and a Chebyshev transformer. ... -
Design of multi-layered radiative cooling structures using evolutionary algorithms
In this work we present a novel way to design thinfilm radiative cooling metamaterials based on genetic algorithms. Three simulations with different design constraints have been done, resulting in three structures that ... -
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ... -
Determining an optimal area to locate a biorefinery under economic and environmental criteria
Facilities location is a strategic decision which has to be carefully considered because it could involve the failure or success of a business. For that reason, anything that helps decision makers to facilitate their ... -
Development and validation of an automatic and intelligent system for medullation and average diameter evaluation to alpaca, llama and mohair fibers
The aim of this work was to develop and validate an automatic and intelligent system (based in artificial intelligence) capable of quantify and identify fibers, by type of medullation in 5 categories. This work was carried ... -
Development of a water flow and velocity optical fiber sensor for field testing
A water flow and velocity fiber optic sensor system was developed and tested. The sensing head was especially developed and ruggedized to measure velocities at different depths, in order to calculate the discharge in channels. -
Development of energy management strategies for the sizing of a fast charging station for electric buses
The electric vehicle contributes to reduce greenhouse gases emissions and get a greater integration of renewable energy. In this context, the implementation of urban buses implies the development of new grid infrastructures ... -
Directions of directional, ordered directional and strengthened ordered directional increasingness of linear and ordered linear fusion operators
In this work we discuss the forms of monotonicity that have been recently introduced to relax the monotonicity condition in the definition of aggregation functions. We focus on directional, ordered directional and strengthened ... -
