Characterization of mechanical properties of adult chests during pre-hospital manual chest compressions through a simple viscoelastic model
(Elsevier, 2023-12)Aim The purpose of this study was to develop a simple viscoelastic model to characterize the mechanical properties of chests during manual chest compressions in pre-hospital cardiopulmonary resuscitation (CPR). Metho ... -
Characterization of non-intentional emissions from distributed energy resources up to 500 kHz: A case study in Spain
(Elsevier, 2019-09-06)[EN] Narrow Band Power Line Communications (NB-PLC) systems are currently used for smart metering and power quality monitoring as a part of the Smart Grid (SG) concept. However, non-intentional emissions generated by the ... -
Characterization of the Potential Effects of EMC Filters for Power Converters on Narrowband Power Line Communications
(MDPI, 2021-01-12)Electromagnetic Compatibility (EMC) filters are one of the main solutions for dealing with the disturbances generated by power inverters. However, they show series/parallel resonances that introduce variations in the ... -
Chemical signatures in fin spine edge of Atlantic bluefin tuna (Thunnus thynnus) can serve as habitat markers of geographically distinct marine environments
(Elsevier, 2022-11)Chemical fingerprints in otoliths are commonly used as natural habitat markers in fishes. Alternatively, the first dorsal fin spine can provide valuable chemical information and may be more suitable for studying (i) ... -
Closed G2 forms and special metrics
(2015-07-10)En esta tesis se aborda el estudio y construcción de variedades G2 calibradas. Una tal variedad es una variedad de Riemann, de dimensión 7, con una métrica de Riemann definida por una cierta 3-forma diferencial, denominada ... -
Closing the loop: Waste valorisation from vegetal sources to develop fruit active films
(Elsevier, 2024-07)Cellulose-rich residue after agar extraction was incorporated into gelatin film forming formulations in order to revalorize it and improve film properties. This revalorized cellulose was compared with the commercial sodium ... -
Cloud Transmission: System Performance and Application Scenarios
(IEEE, 2014)[EN] Cloud Transmission (Cloud Txn) System is a flexible multi-layer system that uses spectrum overlay technology to simultaneously deliver multiple program streams with different characteristics and robustness for ... -
Cohomological tautness of singular Riemannian foliations
(Springer, 2018-11-16)For a Riemannian foliation F on a compact manifold M, J. A. Alvarez Lopez proved that the geometrical tautness of F, that is, the existence of a Riemannian metric making all the leaves minimal submanifolds of M, can be ... -
Combining statistical techniques to predict postsurgical risk of 1-year mortality for patients with colon cancer
(Dove Medical Press, 2018)Introduction: Colorectal cancer is one of the most frequently diagnosed malignancies and a common cause of cancer-related mortality. The aim of this study was to develop and validate a clinical predictive model for 1-year ... -
Crank-Nicholson method for rate equations in powder random lasers
(IOP Publishing, 2015)In this work, we show the resolution of the rate equations in powder random lasers by using the Crank-Nicholson finite difference method. Light propagation in our powders is described by the model of light diffusion. The ... -
Deep Neural Networks for ECG-Based Pulse Detection during Out-of-Hospital Cardiac Arrest
(MDPI, 2019-03-21)The automatic detection of pulse during out-of-hospital cardiac arrest (OHCA) is necessary for the early recognition of the arrest and the detection of return of spontaneous circulation (end of the arrest). The only signal ... -
Definition of the Future Skills Needs of Job Profiles in the Renewable Energy Sector
(MDPI, 2021-05-02)The growth of the renewable energy industry is happening at a swift pace pushed, by the emergence of Industry 4.0. Smart technologies like artificial intelligence (AI), Big Data, the Internet of Things (IoT), Digital Twin ... -
Design, Fabrication and Testing of a High-Sensitive Fibre Sensor for Tip Clearance Measurements
(MDPI, 2018-08)A highly sensitive fibre bundle-based reflective optical sensor has been designed and fabricated for Tip Clearance measurements in a turbine rig. The sensor offers high spatial and temporal resolution. The sensor probe ... -
Development of AI-Based Tools for Power Generation Prediction
(MDPI, 2023-11-16)This study presents a model for predicting photovoltaic power generation based on meteorological, temporal and geographical variables, without using irradiance values, which have traditionally posed challenges and difficulties ... -
Differential distribution pattern of native Ruditapes decussatus and introduced Ruditapes philippinarum clam populations in the Bay of Santander
(Elsevier, 2012-08-29)The aim of the present study is to provide a first characterization of the grooved carpet shell clam Ruditapes decussatus (native) and the Manila clam Ruditapes phillippinarum (nonindigenous) populations in the Bay of ... -
Dinosaur swim tracks from the Lower Cretaceous of La Rioja, Spain: An ichnological approach to non-common behaviours
(Elsevier, 2023-07)The reconstruction of behavioural patterns performed by non-avian dinosaurs is an important task of palaeontology in order to globally understand how these animals interacted with their environment. Their relation with ... -
