Analysis of dominant classes in universal adversarial perturbations
(Elsevier, 2022-01)
The reasons why Deep Neural Networks are susceptible to being fooled by adversarial examples remains an open discussion. Indeed, many different strategies can be employed to efficiently generate adversarial attacks, some ...
Cantera Gorria and Red Ereño: Natural and Cultural Geoheritage (Basque Country, Spain)
(Springer, 2022)
[EN] Construction and ornamental stones are important elements of cultural heritage and geoheritage. The quarries, where these materials are extracted, are a type of site that combines these two types of heritage. Both the ...
Tracking ultrafast dynamics by sub-20-fs UV pulses generated in the lab open atmosphere
(Elsevier, 2023-02)
This study describes a simple method to generate sub-20 fs UV-pulses (264 nm) by third-harmonic generation, in an air-plasma filament formed after focusing the fundamental 800 nm beam directly in the lab open-atmosphere. ...
Syngas production by bio-oil steam gasification in a fountain confined conical spouted bed reactor
(Elsevier, 2023-08)
The combination of delocalized units for the fast pyrolysis of biomass to produce bio-oil followed by centralized units for the gasification of bio-oil appears as an economically attractive option for the full-scale ...
HAKA: HierArchical Knowledge Acquisition in a sign language tutor
(Elsevier, 2023-04)
Communication between people from different communities can sometimes be hampered by the lack of knowledge of each other's language. A large number of people needs to learn a language in order to ensure a fluid communication ...
Parameter and q asymptotics of Lq-norms of hypergeometric orthogonal polynomials
(Wiley, 2023-01)
The three canonical families of the hypergeometric orthogonal polynomials in a
continuous real variable (Hermite, Laguerre, and Jacobi) control the physical
wavefunctions of the bound stationary states of a great number ...
Characterization of PCDD/F and dl-PCB levels in air in Gipuzkoa (Basque Country, Spain)
(Elsevier, 2023-07)
This research examines the levels and trends of pollutants, specifically 17 congeners of PCDD/Fs and 12 dl-PCBs, in the air measured in the province of Gipuzkoa (Basque Country, Spain). The study used PCDD/Fs, dl-PCB, and ...
A comprehensive study of the phase segregation of a urea-based phase change material tested under thermal cycling conditions
(Elsevier, 2023-04)
Eutectic mixtures are used as PCMs due to the possibility to tailor the melting temperatures and mainly because the phase transition occurs at a unique temperature. Eutectic mixtures are assumed to be congruent melting and ...
Environmental corporate social responsibility, R&D and disclosure of “green” innovation knowledge
(Elsevier, 2023-04)
The literature on the environment has analyzed how firms carry out R&D to reduce their pollutant emissions, assuming that they maximize profits. However, empirical evidence shows that firms are increasingly concerned about ...
Design and experimental validation of a piezoelectric actuator tracking control based on fuzzy logic and neural compensation
(Elsevier, 2023-07)
This work proposes two control feedback-feedforward algorithms, based on fuzzy logic in combination with neural networks, aimed at reducing the tracking error and improving the actuation signal of piezoelectric actuators. ...
