Intelligent control of wind-assisted PHEVs smart charging station
(MDPI, 2019)
info:eu-repo/semantics/article,
Two technology opportunities, integration of renewable energy sources and the electrification of vehicles are being encouraged to reduce dependency on fossil fuels and pollution problems. Nevertheless, the huge increase ...
Virtual FBGs using saturable absorbers for sensing with fiber lasers
(MDPI, 2018)
info:eu-repo/semantics/article,
The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
Super-wide impedance bandwidth planar antenna for microwave and millimeter-wave applications
(MDPI, 2019)
info:eu-repo/semantics/article,
A feasibility study of a novel configuration for a super-wide impedance planar antenna is presented based on a 2 × 2 microstrip patch antenna (MPA) using CST Microwave Studio. The antenna comprises a symmetrical arrangement ...
Strong angular dependence of resonant states in 2D dielectric cylinder rings
(AIP Publishing, 2018)
info:eu-repo/semantics/article,
We investigate collective resonators made of dielectric cylinders assembled as two-dimensional regular octagons and decagons. These structures exhibit collective resonance states that change their intensity with the incident ...
Generation of lossy mode resonances in planar waveguides toward development of humidity sensors
(IEEE, 2019)
info:eu-repo/semantics/article,
Lossy mode resonances (LMRs) are typically obtained with optical fibre. The Kretschmann configuration is an alternative but LMRs are generated with angles approaching grazing incidence. In this work, a new setup is explored, ...
Study on isolation improvement between closely-packed patch antenna arrays based on fractal metamaterial electromagnetic bandgap structures
(Institution of Engineering and Technology, 2018)
info:eu-repo/semantics/article,
A decoupling metamaterial (MTM) configuration based on fractal electromagnetic-bandgap (EMBG) structure is shown to significantly enhance isolation between transmitting and receiving antenna elements in a closely-packed ...
Watt-level green random laser at 532 nm by SHG of Yb-doped fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ...
Hybrid method based on topography for robust detection of iris center and eye corners
(ACM (Association for Computing Machinery), 2013)
info:eu-repo/semantics/article,
A multi-stage procedure to detect eye features is presented. Multiresolution and topographic classification are used to detect
the iris center. The eye corner is calculated combining valley detection and eyelid curve ...
Evaluation of accurate eye corner detection methods for gaze estimation
(Bern Open Publishing, 2014)
info:eu-repo/semantics/article,
Accurate detection of iris center and eye corners appears to be a promising approach for low cost gaze estimation. In this paper we propose novel eye inner corner detection methods. Appearance and feature based segmentation ...
Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides
(Nature Research, 2019)
info:eu-repo/semantics/article,
The deposition of an indium oxide (In2O3) thin film on conventional planar waveguides (a coverslip and a glass slide) allows generating lossy mode resonances (LMR) by lateral incidence of light on the waveguide and by ...
