Singular reduction of resonant Hamiltonians
Meyer, Kenneth Ray; Palacián Subiela, Jesús Francisco
; Yanguas Sayas, Patricia (IOP PublishingLondon Mathematical Society, 2018)
Artículo / Artikulua
We investigate the dynamics of resonant Hamiltonians with n degrees of freedom to which we attach a small perturbation. Our study is based on the geometric interpretation of singular reduction theory. The flow of the ... -
Oscillatory motions in restricted N-body problems
Alvarez-Ramírez, Martha; Rodríguez García, Antonio; Palacián Subiela, Jesús Francisco ; Yanguas Sayas, Patricia (Elsevier, 2018)
Artículo / Artikulua
We consider the planar restricted N-body problem where the N−1 primaries are assumed to be in a central configuration whereas the infinitesimal particle escapes to infinity in a parabolic orbit. We prove the existence of ... -
Binary relations coming from solutions of functional equations: orderings and fuzzy subsets
Campión Arrastia, María Jesús; Miguel Turullols, Laura de ; García Catalán, Olga Raquel ; Induráin Eraso, Esteban ; Abrísqueta Usaola, Francisco Javier (World Scientific Publishing Company, 2017)
Artículo / Artikulua
We analyze the main properties of binary relations, defined o n a nonempty set, that arise in a natural way when dealing with real-valued functions that satisfy certain classical functional equations on two variables. We ... -
Assigning numerical scores to linguistic expressions
Campión Arrastia, María Jesús; Falcó Díaz de Cerio, Edurne ; García Lapresta, José; Induráin Eraso, Esteban (MDPI, 2017)
Artículo / Artikulua 
In this paper, we study different methods of scoring linguistic expressions defined on a finite set, in the search for a linear order that ranks all those possible expressions. Among them, particular attention is paid to ... -
Effect of the temperature in the mechanical properties of austenite, ferrite and sigma phases of duplex stainless steels using hardness, microhardness and nanoindentation techniques
Argandoña Salinas, Gorka; Palacio, José; Berlanga Labari, Carlos; Biezma, María V.; Rivero Fuente, Pedro José ; Peña, Julio; Rodríguez Trías, Rafael (MDPI, 2017)
Artículo / Artikulua
The aim of this work is to study the hardness of the ferrite, austenite and sigma phases of a UNS S32760 superduplex stainless steel submitted to different thermal treatments, thus leading to different percentages of the ... -
Stochastic spatio-temporal models for analysing NDVI distribution of GIMMS NDVI3g images
Militino, Ana F.; Ugarte Martínez, María Dolores ; Pérez Goya, Unai (MDPI, 2017)
Artículo / Artikulua
The normalized difference vegetation index (NDVI) is an important indicator for evaluating vegetation change, monitoring land surface fluxes or predicting crop models. Due to the great availability of images provided by ... -
Mid-infrared spectroscopy (MIR) for simultaneous determination of fat and protein content in meat of several animal species
Lozano Saiz, María; Rodríguez Ulibarri, Pablo; Echeverría Morrás, Jesús ; Beruete Díaz, Miguel ; Sorolla Ayza, Mario ; Beriain Apesteguía, María José (Springer, 2017)
Artículo / Artikulua
The aim of this research was to study the application of MIR spectroscopy as an alternative to conventional methods to determine fat and protein content. Samples of the main species used to produce meat products were ... -
Temporal evolution of brain cancer incidence in the municipalities of Navarre and the Basque Country, Spain
Ugarte Martínez, María Dolores; Adin Urtasun, Aritz ; Goicoa Mangado, Tomás ; Casado, Itziar; Ardanaz, Eva; Larrañaga, Nerea (BioMed Central, 2015)
Artículo / Artikulua
Background: Brain cancer incidence rates in Spain are below the European’s average. However, there are two regions in the north of the country, Navarre and the Basque Country, ranked among the European regions with ...
