Nonlinear trapping stiffness of mid-air single-axis acoustic levitators
(American Institute of Physics, 2018)
Artículo / Artikulua,
We describe and experimentally explore a nonlinear stiffness model of the trapping of a solid
particle in a single-axis acoustic levitator. In contrast to the commonly employed linear stiffness
assumption, our nonlinear ...
A comprehensive model for lithium-ion batteries: from the physical principles to an electrical model
(Elsevier, 2018)
Artículo / Artikulua,
The growing interest in e-mobility and the increasing installation of renewable energy-based systems are leading to rapid improvements in lithium-ion batteries. In this context, battery manufacturers and engineers require ...
The influence of entrepreneurs’ social referents on start-up size
(Springer, 2018)
Artículo / Artikulua,
This paper uses social comparison theory to explore the effect that the average size of established businesses at the regional (provincial) level may have on start-up size. It is argued that established entrepreneurs at ...
Machines and energy. Energy capital ratios in Europe and Latin America 1875 - 1970'
(Taylor & Francis, 2018)
Artículo / Artikulua,
The relationship between energy and capital is one of the most important
aspects of modern economic growth. Machines need energy to produce all
the goods we enjoy; energy would be far less useful for humankind in
absence ...
Online detection of pathological TCP flows with retransmissions in high-speed networks
(Elsevier, 2018)
Artículo / Artikulua,
Online Quality of Service (QoS) assessment in high speed networks is one of the key concerns for service providers, namely to detect QoS degradation on-the-fly as soon as possible and avoid customers’ complaints. In this ...
Label-free wavelength and phase detection based SMS fiber immunosensors optimized with cladding etching
(Elsevier, 2018)
Artículo / Artikulua,
The performance of E-SMS (Etched Singlemode-Multimode-Singlemode) optical fiber structures as immunosensors has been assessed by the implementation of antibody/antigen immunoassays. Through this procedure
it has been ...
Long period fiber grating for biosensing: an improved design methodology to enhance add-layer sensitivity
(IEEE, 2018)
Artículo / Artikulua,
We present our theoretical study on the design of
LPFG sensor where its add-layer sensitivity is enhanced. addlayer
sensitivity quantifies the sensitivity of the sensor to the
changes taking place within few tens of ...
Trends in hospital morbidity from Alzheimer's disease in the European Union, 2000-2014
(SAGE, 2018)
Artículo / Artikulua,
Background: Alzheimer’s disease (AD) has become a concerning public health issue. We aimed to analyse the trends of hospital morbidity from AD in the European Union (EU) in the period 2000-2014.
Methods: Data from ...
El PCI como recurso didáctico para el desarrollo de las nuevas alfabetizaciones: una experiencia en los Grados de Maestro
(Universidad Politècnica de València, 2018)
Artículo / Artikulua,
Una experiencia didáctica desarrollada con el alumnado de los Grados de Maestro en Infantil y Primaria de la Universidad Pública de Navarra muestra que el Patrimonio Cultural Inmaterial (PCI) es un recurso didáctico que ...
Parameter-independent control for battery chargers based on virtual impedance emulation
(IEEE, 2018)
Artículo / Artikulua,
An effective battery voltage regulation is fundamental to extend battery lifetime and to avoid overvoltage. However, the design of this regulation is complicated due to the wide battery impedance range, which, when dealing ...
