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 ...
Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves
(AIP Publishing, 2014)
Artículo / Artikulua,
A zoned fishnet metamaterial lens is designed, fabricated, and experimentally demonstrated at millimeter wavelengths to work as a negative near-zero refractive index lens suitable for compact lens antenna configurations. ...
Phasorial differential pulse-width pair technique for long-range Brillouin optical time-domain analysis sensors
(Optical Society of America, 2014)
Artículo / Artikulua,
We introduce a novel phasorial differential pulse width pair (PDPP) method for Brillouin optical time domain analysis (BOTDA) sensors that combines spatial resolution enhancement with increased tolerance to non local ...
Implementation and control of a residential electrothermal microgrid based on renewable energies, a hybrid storage system and demand side management
(MDPI, 2014)
Artículo / Artikulua,
This paper proposes an energy management strategy for a residential electrothermal microgrid, based on renewable energy sources. While grid connected, it makes use of a hybrid electrothermal storage system, formed by a ...
Micro-displacement sensor combined with a fiber ring interrogated by an optical time-domain reflectometer
(IEEE, 2014)
info:eu-repo/semantics/article,
A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an OTDR is presented. The sensor configuration is characterized for measuring both longitudinal ...
Comparative study of ring and random cavities for fiber lasers
(Optical Society of America, 2014)
info:eu-repo/semantics/article,
An experimental comparison of three fiber laser structures with the same Raman gain medium is presented in order to establish the main pros and cons of each basic scheme. The first fiber laser is based on a hybrid ring–random ...
Compact dual-band terahertz quarter-wave plate metasurface
(IEEE, 2014)
info:eu-repo/semantics/article,
A dual-band quarter-wave plate based on a modified extraordinary transmission hole array is numerically analyzed and experimentally demonstrated at terahertz frequencies. To control independently orthogonal polarizations, ...
Novel sensor design using photonic crystal fibres for monitoring the onset of corrosion in reinforced concrete structures
(IEEE, 2014)
info:eu-repo/semantics/article,
In this paper, a novel sensing technique has been designed and investigated for the direct, in situ detection of steel corrosion distributed in reinforced concrete structures. At present, structural health monitoring in ...
Mapping smooth profile H-plane rectangular waveguide structures to substrate integrated waveguide technology
(Institution of Engineering and Technology, 2014)
info:eu-repo/semantics/article,
The guidelines for mapping rectangular waveguide structures to substrate integrated waveguide (SIW) technology are well understood for structures with straight walls. However, the mapping of a smooth profile structure from ...
Growth in the number of references in engineering journal papers during the 1972-2013 period
(Springer, 2014)
info:eu-repo/semantics/article,
The number of references per paper, perhaps the best single index of a journal’s scholarliness, has been studied in different disciplines and periods. In this paper we present a four decade study of eight engineering ...
