Particularised Kalman filter for the state-of-charge estimation of second-life lithium-ion batteries and experimental validation
A critical issue for a proper energy management of a lithium-ion (Li-ion) battery is the estimation of its state-of-charge (SOC). There are various methods available for the SOC estimation, being some of them robust and ... -
Performance evaluation of spatial modulation patterns in compressive sensing terahertz imaging
Terahertz (THz) imaging traditionally uses pixel-to-pixel mechanical raster scanning, which is slow and limits the resolution and potential applications. Compressive Sensing Terahertz (CS-THz) imaging has the potential to ... -
The promising combination of thermoelectric generators with IoT technologies for autonomous monitoring systems
Monitoring stations becomes essential in any volcanic system in the world but, because of their remote location, both the electricity supply and the communications represent a technological challenge. The present work ... -
Quasi-distributed vibration analysis of a cantilever beam using OFDR and weak reflectors
This work evaluates the performance of a quasi-distributed in-line velocimeter based on OFDR and weak reflectors to measure vibration every 10 cm, using a cantilever beam under free-end damping and during an impact-hammer test. -
Ramp-rate control in large PV plants: battery vs. short-term forecast
The changeability in the power produced by utility-scale PV plants caused by shadows due to passing clouds can compromise grid stability. Traditionally, some kind of energy storage systems (ESS) is proposed as the solution ... -
Ransomware encrypted your files but you restored them from network traffic
(IEEE, 2019) Contribución a congreso / Biltzarrerako ekarpenaIn a scenario where user files are stored in a network shared volume, a single computer infected by ransomware could encrypt the whole set of shared files, with a large impact on user productivity. On the other hand, medium ... -
Rheumatoid arthritis miRNA biomarker detection by means of LMR based fiber-optic biosensor
Development of miRNA optical biosensors for disease diagnosis and monitoring has acquired relevance in recent years, due to the clinical importance of miRNA and the inherent advantages of optical sensors. Here, we present ... -
Sensorless active damping strategy for parallel interleaved voltage source power converters with LCL filter
Grid-connected pulse-width modulation converters with LCL filters are widely extended as an interface for renewable energy generating systems. Those filters arise stability issues due to the filter resonance, which, must ... -
SeTA: semiautomatic tool for annotation of eye tracking images
Availability of large scale tagged datasets is a must in the field of deep learning applied to the eye tracking challenge. In this paper, the potential of Supervised-Descent-Method (SDM) as a semiautomatic labelling tool ... -
Silicon-based 0.450-0.475 THz series-fed double dielectric resonator on-chip antenna array based on metamaterial properties for integrated-circuits
The antenna array designed to operate over 0.450-0.475 Terahertz comprises two dielectric resonators (DRs) that are stacked vertically on top of each other and placed on the surface of the slot antenna fabricated on a ... -
Sistema de interrogación multi-sensor basado en multiplexación en longitud de onda y tiempo
En este trabajo se propone un sistema de interrogación versátil y económico basada en la generación de pulsos empleando la modulación directa de diodos láser DFB. Se ha demostrado una resolución en longitud de onda de 1 ... -
Stable L-band fiber laser sensor using a backscattering-based multimode fiber reflector
A new and highly stable L-band fiber laser for sensing is demonstrated. An emission line at 1575.47 nm, was achieved using a special reflector. Good strain sensitivity, optical signal to noise ratio and output power stability ... -
Study on antenna mutual coupling suppression using integrated metasurface isolator for SAR and MIMO applications
A metasurface based decoupling structure that is composed of a square-wave slot pattern with exaggerated corners that is implemented on a rectangular microstrip provides high-isolation between adjacent patch antennas for ... -
Sub-synchronous resonance damper based on the stator voltage feedback for DFIG wind turbines
Doubly-fed induction generator (DFIG) wind turbines connected to series compensated grids are prone to sub-synchronous resonance (SSR) instability. In this paper we develop a model to analyze SSRs and propose a damping ... -

A simple technique to greatly enhance the DC open-loop gain of a Miller op-amp is introduced here. It is based on the utilization of nested regulated cascode amplifiers. It uses conventional Miller compensation and does ... -
Supervised descent method (SDM) applied to accurate pupil detection in off-the-shelf eye tracking systems
The precise detection of pupil/iris center is key to estimate gaze accurately. This fact becomes specially challenging in low cost frameworks in which the algorithms employed for high performance systems fail. In the last ... -
Suppressing open stopband for terahertz periodic microstrip leaky-wave antennas
This paper reports on a periodic microstrip Leaky-wave antenna (LWA). The open stopband issue is suppressed by altering the unit cell using a matching stub. The developed LWA is based on a grounded InP-substrate of 50 ... -
