Gas analyzer's drift leads to systematic error in maximal oxygen uptake and maximal respiratory exchange ratio determination
(Frontiers Media, 2015-10)
The aim was to examine the drift in the measurements of fractional concentration of oxygen (FO2) and carbon dioxide (FCO2) of a Nafion-using metabolic cart during incremental maximal exercise in 18 young and 12 elderly ...
Detecting the presence-absence of bluefin tuna by automated analysis of medium-range sonars on fishing vessels
(Public Library Science, 2017-02-02)
This study presents a methodology for the automated analysis of commercial medium range sonar signals for detecting presence/absence of bluefin tuna (Tunnus thynnus) in the Bay of Biscay. The approach uses image processing ...
Sima de Illobi (Aralar, Navarra) yacimiento de oso pardo ( U. arctos Linnaeus, 1758). Estudio taxonómico y tafonómico
(Sociedad de Ciencias Aranzadi = Aranzadi Zientzia Elkarteak, 2011-12-07)
[ES] En este trabajo, presentamos los resultados logrados del estudio del conjunto paleontológico de la Sima de Illobi (Aralar, Navarra). Este estudio consta de dos partes, análisis taxonómico y tafonómico.
En la primera, ...
Restos esqueléticos de osos ( Ursus arctos y Ursus spelaeus) en el oriente de la Región Cantábrica. Distribución geográfica y análisis biométrico
(Sociedad de Ciencias Aranzadi = Aranzadi Zientzia Elkarteak, 2015-05-29)
[ES] En este trabajo se presenta un amplio conjunto paleontológico recuperado en treinta y cuatro cavidades situadas en la mitad oriental de los Montes Vascos. Los restos estudiados fueron recopilados durante cuatro décadas ...
En la ruta occidental del poblamiento de la Península Ibérica
(Sociedad de Ciencias Aranzadi = Aranzadi Zientzia Elkarteak, 2016-12-01)
[ES] Tradicionalmente, viene considerándose que el paso de los grupos humanos por los Pirineos resulta dificultoso durante el Paleolítico y existen, efectivamente, datos que contradicen este planteamiento. Incluso podemos ...
Genetic turnovers and northern survival during the last glacial maximum in European brown bears
(John Wiley & Sons, 2019-05-29)
The current phylogeographic pattern of European brown bears (Ursus arctos) has
commonly been explained by postglacial recolonization out of geographically distinct
refugia in southern Europe, a pattern well in accordance ...
Novel control algorithm for MPPT with Boost converters in photovoltaic systems
(Elsevier, 2017-07)
The great advances in efficiency and performance of photovoltaic modules would not be very useful if they do not work close to their maximum power point (MPP). In this paper a novel Sliding Mode Control (SMC) based algorithm ...
Contributions of Bottom-Up Energy Transitions in Germany: A Case Study Analysis
(MDPI, 2017-04)
Within the context of an energy transition towards achieving a renewable low-impact energy consumption system, this study analyses how bottom-up initiatives can contribute to state driven top-down efforts to achieve the ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Robust labeling of human motion markers in the presence of occlusions
(Elsevier, 2019-08-11)
Human motion capture by optical sensors produces snapshots of the motion of a cloud of points that need to be labeled in order to carry out ensuing motion analysis for medical or other purposes. We generate the labeling ...
