A Logistic Approach for Kinetics of Isothermal Pyrolysis of Cellulose
López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Tarrío-Saavedra, Javier; Naya, Salvador; Artiaga, Ramón (MDPI, 2021-03)[Abstract] A kinetic model is proposed to fit isothermal thermogravimetric data obtained from cellulose in an inert atmosphere at different temperatures. The method used here to evaluate the model involves two steps: (1) ... -
Application of residuals from purification of bivalve molluscs in Galician to facilitate marine ecosystem resiliency through artificial reefs with shells – One generation
Carral Couce, Luis; Lamas, M.I.; Buenhombre, José Luis Mier; Cartelle Barros, Juan José; Naya, Salvador; Tarrío-Saavedra, Javier (Elsevier, 2023-01-15)[Abstract] The seas and oceans of the planet provide a wide range of essential resources. However, marine ecosystems are undergoing severe degradation due to the unsustainable exploitation and consumption patterns of the ... -
Automatic detection of defective crankshafts by image analysis and supervised classification
Remeseiro, Beatriz; Tarrío-Saavedra, Javier; Francisco-Fernández, Mario; Penedo, Manuel; Naya, Salvador; Cao, Ricardo (2019)[Abstract]: A crankshaft is a mechanical component of an engine that performs a conversion of an alternative movement of a piston in a rotational motion of a shaft. It is a critical part and one of the most expensive of ... -
Constructing a Control Chart Using Functional Data
Flores, Miguel; Naya, Salvador; Fernández-Casal, Rubén; Zaragoza, Sonia; Raña, Paula; Tarrío-Saavedra, Javier (MDPI AG, 2020-01-02)[Abstract] This study proposes a control chart based on functional data to detect anomalies and estimate the normal output of industrial processes and services such as those related to the energy efficiency domain. Companies ... -

Tarrío-Saavedra, Javier; Orois, Elena; Naya, Salvador (Universidad Nacional Autónoma de México, 2017)[Resumen] Este trabajo representa una nueva alternativa para el estudio, clasificación y comparación de la producción científica de centros de investigación, utilizando las funciones de tratamiento de datos del paquete ... -
Local Correlation Integral Approach for Anomaly Detection Using Functional Data
Sosa, Jorge; Flores, Miguel; Naya, Salvador; Tarrío-Saavedra, Javier (MDPI, 2023-02-06)[Abstract]: The present work develops a methodology for the detection of outliers in functional data, taking into account both their shape and magnitude. Specifically, the multivariate method of anomaly detection called ... -
Modelling Operative and Routine Learning Curves in Manoeuvres in Locks and in Transit in the Expanded Panama Canal
Carral Couce, Luis; Tarrío-Saavedra, Javier; Vega Sáenz, Adán; Bogle, Johnny; Alemán, Gabriel; Naya, Salvador (Cambridge University Press, 2021-05)[Abstract] Piloting in the Panama Canal is exceptional as, due to its importance, the functions of the captains of vessels are taken over by pilots. Hence, prior to inauguration of the expanded canal, a limited number of ... -
