Upper bounds on scattering processes and metamaterial-inspired structures that reach them
(IEEE, 2014)
Artículo / Artikulua,
The physical limitations on time-harmonic scattering processes are investigated on the basis of the optical theorem. Previously derived least upper bounds on the total scattering and absorption cross-sections are obtained ...
Synthesis of Brillouin frequency shift profiles to compensate non-local effects and Brillouin induced noise in BOTDA sensors
(Optical Society of America, 2014)
Artículo / Artikulua,
We present a novel technique for Brillouin optical time domain analysis (BOTDA) sensors that simultaneously compensates non local effects and reduces Brillouin noise. The technique relies on the wavelength modulation of ...
Terajets produced by dielectric cuboids
(AIP Publishing, 2014)
Artículo / Artikulua,
The capability of generating terajets using three-dimensional (3D) dielectric cuboids working at terahertz (THZ) frequencies (as analogues of nanojets in the infrared band) is introduced and studied numerically. The focusing ...
Electromyographic, cerebral, and muscle hemodynamic responses during intermittent, isometric contractions of the biceps brachii at three submaximal intensities
(Frontiers Media, 2014)
info:eu-repo/semantics/article,
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 ...
A fiber optic ammonia sensor using a universal pH indicator
(MDPI, 2014)
Artículo / Artikulua,
A universal pH indicator is used to fabricate a fiber optic ammonia sensor. The advantage of this pH indicator is that it exhibits sensitivity to ammonia over a broad wavelength range. This provides a differential response, ...
Radio characterization for ISM 2.4 GHz wireless sensor networks for judo monitoring applications
(MDPI, 2014)
Artículo / Artikulua,
In this work, the characterization of the radio channel for ISM 2.4GHz Wireless Sensor Networks (WSNs) for judo applications is presented. The environments where judo activity is held are usually complex indoor scenarios ...
Generation of surface plasmon resonance and lossy mode resonance by thermal treatment of ITO thin-films
(Elsevier, 2014)
Artículo / Artikulua,
Silicon wafers coated with IndiumTinOxide (ITO) by application of sputtering technique have been
characterized after different post-annealing techniques, showing that this last factor is critical for the
quality of the ...
Control strategies to smooth short-term power fluctuations in large photovoltaic plants using battery storage systems
(MDPI, 2014)
Artículo / Artikulua,
The variations in irradiance produced by changes in cloud cover can cause rapid fluctuations in the power generated by large photovoltaic (PV) plants. As the PV power share in the grid increases, such fluctuations may ...
Gasohol quality control for real time applications by means of a multimode interference fiber sensor
(MDPI, 2014)
Artículo / Artikulua,
In this work we demonstrate efficient quality control of a variety of gasoline and ethanol (gasohol) blends using a multimode interference (MMI) fiber sensor. The operational principle relies on the fact that the addition ...
Analysis matrix for smart cities
(MDPI, 2014)
Artículo / Artikulua,
The current digital revolution has ignited the evolution of communications grids and the development of new schemes for productive systems. Traditional technologic scenarios have been challenged, and Smart Cities have ...
