Analytics of type IIB flux vacua and their mass spectra
; ; ; Álvarez Urquiola, Mikel (Springer, 2023-01)
We analyze the tree-level potential of type IIB flux compactifications in warped Calabi-Yau orientifolds, in regions of weak coupling and moderately large complex structure. In this regime, one may approximate the flux-induced ... -
Angle-resolved direct emissivity measurements on unencapsulated solar cells for passive thermal control
González de Arrieta Martinez, Iñigo; Echániz Ariceta, Telmo ; ; López, Gabriel Alejandro (IEEE, 2024-03-18)
The emissivity of two unencapsulated photovoltaic cells has been measured by a direct radiometric method, between 30 and 50 °C, and indirectly at room temperature. The advantages of the angle-resolved direct method for the ... -

An extension of the online implantation chamber used for emission Mossbauer Spectroscopy (eMS) at ISOLDE/CERN that allows for quick removal of samples for offline low temperature studies is briefly described. We demonstrate ... -
Application of the k-Prototype Clustering Approach for the Definition of Geostatistical Estimation Domains
; Alberdi Celaya, Elisabete; ; (MDPI, 2023-02-01)
The definition of geostatistical domains is a stage in the estimation of mineral resources, in which a sample resulting from a mining exploration process is divided into zones that show homogeneity or minimal variation in ... -
Aspects of quality control of wind profiler measurements in complex topography
(Copernicus Gesellschaft, 2014)It is well known in the scientific community that some remote sensing instruments assume that sample volumes present homogeneous conditions within a defined meteorological profile. At complex topographic sites and under ... -
Assessing the suitability of the minimum capture size and protection regimes in the gooseneck barnacle shellfishery
(Elsevier, 2014-12-19)The suitability of a total-length-based, minimum capture-size and different protection regimes was investigated for the gooseneck barnacle Pollicipes pollicipes shellfishery in N Spain. For this analysis, individuals that ... -
Assessment of Biomass Energy Potential and Forest Carbon Stocks in Biscay (Spain)
Mateos Sánchez, Esperanza; ; (MDPI, 2016-03)
The aim of this research is to identify, quantify and characterize the potential available forest biomass of Pinus radiata D. Don and Eucalyptus globulus Labill. across Biscay province in northern Spain. In order to do ... -
Assessment of the Evolution of End-Tidal Carbon Dioxide within Chest Compression Pauses to Detect Restoration of Spontaneous Circulation
Gutiérrez Ruiz, José Julio; Leturiondo Sota, Mikel ; Ruiz de Gauna Gutiérrez, Sofía ; Ruiz Ojeda, Jesús María ; ; ; ; ; (Public Library Of Science, 2021-05-18)
Background Measurement of end-tidal CO2 (ETCO2) can help to monitor circulation during cardiopulmonary resuscitation (CPR). However, early detection of restoration of spontaneous circulation (ROSC) during CPR using ... -
BAMS: A Tool for Supervised Burned Area Mapping Using Landsat Data
; Alvarado Herrán, María Teresa; Artano Pérez, Karmele ; Martinez Blanco, Maria Pilar ; Mesanza Moraza, Amaia ; Torre Tojal, Leyre ; ; (MDPI, 2014-12)
A new supervised burned area mapping software named BAMS (Burned Area Mapping Software) is presented in this paper. The tool was built from standard ArcGIS (TM) libraries. It computes several of the spectral indexes most ... -
Bayesian network-based over-sampling method (BOSME) with application to indirect cost-sensitive learning
(Nature, 2022-05)Traditional supervised learning algorithms do not satisfactorily solve the classification problem on imbalanced data sets, since they tend to assign the majority class, to the detriment of the minority class classification. ... -
Beach management policy analysis concerning safety flag systems in Northern Spain
