Influence of the conductor temperature error on the overhead line ampacity monitoring systems
Albizu Flórez, Igor
; Fernández Herrero, Elvira ; Mazón Sainz-Maza, Angel Javier ; Bengoechea Aresti, Janire (The Institution of Engineering and Technology, 2011-04)
Many real time overhead line ampacity monitoring systems are based on the calculation of the wind speed. The wind speed is obtained from the conductor temperature. The conductor temperature can be measured directly or it ... -
Influence of Training Set Selection in Artificial Neural Network-Based Propagation Path Loss Predictions
(Hindawi Publishing Corporation, 2012)This paper analyzes the use of artificial neural networks (ANNs) for predicting the received power/path loss in both outdoor and indoor links. The approach followed has been a combined use of ANNs and ray-tracing, the ... -
Microcantilever arrays functionalised with spiropyran photoactive moieties as systems to measure photo-induced surface stress changes
Grogan, Catherine; Florea, Larisa; Koprivica, Slavica; Scarmagnani, Silvia; O’Neill, Luke; Lyng, Fiona; Pedreschi, Fran; Benito López, Fernando; Raiteri, Roberto (Elsevier, 2016-12)
[EN] Herein we investigate the feasibility of detecting photo-induced surface stress changes using the deflection response of cantilevers. For this purpose, silicon microcantilevers have been functionalised with spiropyran ... -
On the Selection of Non-Invasive Methods Based on Speech Analysis Oriented to Automatic Alzheimer Disease Diagnosis

The work presented here is part of a larger study to identify novel technologies and biomarkers for early Alzheimer disease (AD) detection and it focuses on evaluating the suitability of a new approach for early AD diagnosis ... -
On-demand generation and removal of alginate biocompatible microvalves for flow control in microfluidics
Sáez Castaño, Janire; Etxebarria Elezgarai, Jaione; Antoñana Díez, Marta; Benito López, Fernando (Elsevier, 2016-10-29)
[EN] This paper describes, for the first time, the use of alginate hydrogels as miniaturised microvalves within microfluidic devices. These biocompatible and biodegradable microvalves are generated in situ and on demand, ... -
Optimization of solution-processed oligothiophene:fullerene based organic solar cells by using solvent additives
(Beilstein Institut, 2013-10)The optimization of solution-processed organic bulk-heterojunction solar cells with the acceptor-substituted quinquethiophene DCV5T-Bu-4 as donor in conjunction with PC61BM as acceptor is described. Power conversion ... -
Proof of Concept of Impact Detection in Composites Using Fiber Bragg Grating Arrays
Gómez, Javier; Jorge, Iagoba; Durana Apaolaza, Gaizka; Arrue Aramburu, Juan Antonio ; ; ; Montero, Ander; López, Ion (MDPI, 2013-09)
Impact detection in aeronautical structures allows predicting their future reliability and performance. An impact can produce microscopic fissures that could evolve into fractures or even the total collapse of the structure, ... -
Query-by-Example Spoken Term Detection ALBAYZIN 2012 evaluation: overview, systems, results, and discussion
(Springer, 2013-09)Query-by-Example Spoken Term Detection (QbE STD) aims at retrieving data from a speech data repository given an acoustic query containing the term of interest as input. Nowadays, it has been receiving much interest due to ... -
RESTful Discovery and Eventing for Service Provisioning in Assisted Living Environments
(MDPI, 2014-05)Service provisioning in assisted living environments faces distinct challenges due to the heterogeneity of networks, access technology, and sensing/actuation devices in such an environment. Existing solutions, such as ... -
STM study on the self-assembly of oligothiophene-based organic semiconductors
(Beilstein Institut, 2011-11)The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The ... -
Techniques for On-Line Diagnosis of Stator Shorted Turns in Induction Motors
Albizu Flórez, Igor; ; Mazón Sainz-Maza, Angel Javier ; Tapia Otaegui, María Aranzazu (Taylor & Francis, 2006-01)
In low voltage induction motors, the first indication of a stator fault is the appearance of an inter-turn short circuit. For this reason, several attempts to diagnose reliably these short circuits have been made. Although ... -
