Effect of both protective and reducing agents in the synthesis of multicolor silver nanoparticles
In this paper, the influence of variable molar ratios between reducing and loading agents (1:100, 1:50, 1:20, 1:10, 1:5, 1:2, 1:1, 2:1) and between protective and loading agents (0.3:1, 0.75:1, 1.5:1, 3:1, 7.5:1, 30:1, ... -
Effect of the glottal source and the vocal tract on the partials amplitude of vibrato in male voices
In this paper the production of vocal vibrato is investigated. The most relevant features of the acoustical vibrato signal, frequency and amplitude variations of the partials, will be related to the voice production ... -
Effects of pump pulse extinction ratio in Brillouin optical time-domain analysis sensors
We report on two previously unknown non-local effects that have been found to impair Brillouin optical time-domain analysis (BOTDA) sensors that deploy limited extinction ratio (ER) pump pulses. The first one originates ... -
Efficient implementation of GALS systems over comercial synchronous FPGAs: a new approach
This paper introduces a new approach for implementing Glocally Asynchronous – Locally Synchronous (GALS) systems over commercial available Field Programmable Gate Arrays (FPGA). This new vision is aimed to overcome the ... -
Egituren egoeraren monitorizaziorako zuntz optikoan oinarritutako sentsore sinplifikatua
Brillouin hedatuko denbora eremu optikoaren analisian (BOTDA) oinarritutako sentsoreak, estruktura handien (100 km luzerako estrukturak) deformazioa eta tenperatura neurtzeko gaitasuna dute. Lan honetan, BOTDA konfigurazio ... -
Electro-thermal modelling of a supercapacitor and experimental validation
This paper reports on the electro-thermal modelling of a Maxwell supercapacitor (SC), model BMOD0083 with a rated capacitance of 83 F and rated voltage of 48 V. One electrical equivalent circuit was used to model the ... -
Electroinductive waves in chain of complementary metamaterial elements
Electronductive waves supported by chains of resonators drilled on a metallic plate are presented. Propagation of energy comes as a consequence of the electric coupling between these resonators. Therefore, these waves ... -
Electroinductive waves role in left-handed stacked complementary split rings resonators
In this letter it is presented a Left-Handed Metamaterial design route based upon stacked arrays of screens made of complementary split rings resonators under normal incidence in the microwave regime. Computation of ... -
Electromagnetic band gap technology for millimetre wave applications
En esta tesis se ha estudiado el uso de estructuras Electromagnetic Bandgap (EBG) para frecuencias en la banda de las millimétricas. Estas frecuencias son muy apropiadas para aplicaciones de generación de imágenes ... -
Electromagnetic cloaking with canonical spiral inclusions
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 ... -
Electromagnetic response of extraordinary transmission plates inspired on Babinet’s principle
This chapter is devoted to polarization effects arisen from perforated metallic plates exhibiting extraordinary transmission (ET). Setting aside the state-of-the-art of perforated metallic plates, we show that by applying ... -
Electromangetic force density in electrically and magnetically polarizable media
The force density induced by electromagnetic fields in electrically and magnetically polarizable media is studied analytically. Different formulations of the force density as a function of field-related quantities, ... -
Electromyographic, cerebral, and muscle hemodynamic responses during intermittent, isometric contractions of the biceps brachii at three submaximal intensities
This study examined the electromyographic, cerebral and muscle hemodynamic responses during intermittent isometric contractions of biceps brachii at 20, 40, and 60% of maximal voluntary contraction (MVC). Eleven volunteers ... -
Electronic controlled device for the analysis and design of photovoltaic systems
The characterization and design of photovoltaic systems is a difficult issue due to the variable operation atmospheric conditions. With this aim, simulators and measurement equipments have been proposed. However, most of ... -
Electronic model-driven health computing platforms in the management of chronicity: contributions to integration and harmonization of e-health standards and modelling efficient eophthalmology services
En general, los servicios de salud se diseñan para tratar episodios agudos, mientras que las enfermedades crónicas consumen cerca del 80% del presupuesto de los servicios nacionales de salud debido a una gestión subóptima ... -
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 ...
