EMG modeling
The aim of this chapter is to describe the approaches used for modelling electromyographic (EMG) signals as well as the principles of electrical conduction within the muscle. Sections are organized into a progressive, ... -
Enabling personal privacy for pervasive computing environments
Protection of personal data in the Internet is already a challenge today. Users have to actively look up privacy policies of websites and decide whether they can live with the terms of use. Once discovered, they are ... -
End-of-fiber signals strongly influence the first and second phases of the M wave in the vastus lateralis: implications for the study of muscle excitability
It has been recurrently observed that, for compound muscle action potentials (M wave) recorded over the innervation zone of the vastus lateralis, the descending portion of the first phase generally shows an 'inflection' ... -
Energy management strategy for a battery-diesel stand-alone system with distributed PV generation based on grid frequency modulation
A hybrid PV-Battery-Diesel configuration is very attractive for stand-alone systems in terms of cost and reliability. In many applications, the battery and the diesel generator are centralized and generate the AC grid while ... -
Energy storage systems based on lithium-ion batteries and supercapacitors: characterization, modelling and integration with renewable energies
Los inconvenientes medioambientales, sociales y económicos que presentan los combustibles fósiles y nucleares están propiciando un uso cada vez mayor de fuentes de energía renovables. El fuerte desarrollo tecnológico de ... -
Enhanced radiation properties of a rectangular waveguide by means of a left handed media
In this paper, the results of experimental investigations to improve the gain between two antennas by means of a Left Handed Material (LHM) are presented. The basic idea is the use of a LHM media acting as a resonator ... -
Enhanced tolerance to pulse extinction ratio in Brillouin optical time domain analysis sensors by dithering of the optical source
We demonstrate the relaxation of the stringent requirements placed on the pulse extinction ratio in long-range Brillouin optical time-domain analysis sensors (BOTDA) by modulating the wavelength of the laser source that ... -
Enhancement of sensitivity in long period fiber gratings with deposition of low refractive index materials
It was proved [Opt. Lett. 30, 720 (2005)] that the deposition of an overlay of higher refractive index than that of the cladding on a long-period fiber grating (LPFG) causes large shifts in the attenuation bands induced by ... -
Enhancement of signal-to-noise ratio in Brillouin optical time domain analyzers by dual-probe detection
We demonstrate a simple technique to enhance the signal-to-noise ratio (SNR) in Brillouin optical time-domain analysis sensors by the addition of gain and loss processes. The technique is based on the shift of the pump ... -
Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ... -
Enhancement of the power radiated by a dipole antenna at boresight by means of a left handed superstrate
In this paper a comparison between the measured radiation performances of a single dipole and a dipole with a left handed superstrate based on a finite periodic repetition of a unit cell is presented. First of all the ... -

Enhancing the infrared and visible emission properties of calcium silicate hydrate for radiative cooling using metamaterials
Two periodic structures composed of metal cylinders with different orientations are used to improve the solar reflection of calcium silicate hydrate (CSH) while maintaining its atmospheric emission. Interesting effects ... -
eOftalmología: estado actual y tendencias futuras
La eSalud se puede definir como el uso de las tecnologías de la información y las comunicaciones para proporcionar o apoyar un diverso grupo de actividades relacionadas con la atención en salud. Si este concepto se ... -
Epsilon-near-zero metalenses operating in the visible
Several converging lenses working in the permittivity near to zero (ENZ) regime at optical frequencies are designed using an array of metal-dielectric-metal plasmonic waveguides. These plasmonic waveguides show a dispersive ... -
Erratum: “Transmission spectra changes produced by decreasing compactness of opal like structures” J. Appl. Phys. 105, 024910 (2009)
Performing a systematic review of our experimental data, we have realized that we introduced a significant mistake in our abovementioned publication. Figure 3 did not correspond to the situation described, and should be ... -
ESA-based in-fiber nanocavity for hydrogen–peroxide detection
A fiber-optic sensor sensitive to hydrogen peroxide has been designed based on the electrostatic layer-by-layer selfassembly method. Prussian blue has been deposited in a polymeric structure formed by Poly(allylamine ... -
Estado del arte de las antenas que combinan corrugaciones horizontales y verticales
