(Gobierno de Navarra, 2009)
Artículo / Artikulua,
La electromiografía clínica es una metodología de registro y análisis de la actividad bioeléctrica del músculo esquelético orientada al diagnóstico de las enfermedades neuromusculares. Las posibilidades de aplicación y el ...
Fisiopatología y técnicas de registro de los movimientos oculares
(Gobierno de Navarra, 2009)
Artículo / Artikulua,
En el control de la motilidad ocular intervienen varios sistemas funcionales. Los reflejos vestíbulo-oculares y optocinéticos son respuestas automáticas para compensar los movimientos de la cabeza y del entorno visual y ...
Electromagnetic cloaking with canonical spiral inclusions
(IOP Publishing Ltd., 2008)
Artículo / Artikulua,
We report an electromagnetic cloaking structure that is composed of identical canonical spiral particles. By using the Clausius-Mosotti formula, the electric and magnetic polarizabilities of a single spiral particle are ...

Arrangements of via-holes in microstrip lines as metallodielectric periodic structures
(Wiley, 2000)
Artículo / Artikulua,
In this paper, the use of via holes in microstrip lines to design periodic structures that can be regarded as metallodielectric electromagnetic crystals is analyzed. The proposed novel periodic structures achieve a notably ...
Vibrato in singing voice: the link between source-filter and sinusoidal models
(Springer Open, 2004)
Artículo / Artikulua,
The application of inverse filtering techniques for high-quality singing voice analysis/synthesis is discussed. In the context of source-filter models, inverse filtering provides a noninvasive method to extract the voice ...
Influence of the power supply on the energy efficiency of an alkaline water electrolyser
(Elsevier, 2009)
Artículo / Artikulua,
Electric energy consumption represents the greatest part of the cost of the hydrogen
produced by water electrolysis. An effort is being carried out to reduce this electric
consumption and improve the global efficiency ...
