Ordered directional monotonicity in the construction of edge detectors
(Elsevier, 2021)
info:eu-repo/semantics/article,
In this paper we provide a specific construction method of ordered directionally monotone functions. We show that the functions obtained with this construction method can be used to build edge detectors for grayscale images. ...
Novel concentric hexagonal-shaped RFID tag antenna with T-shaped stub matching
(IEEE, 2021)
info:eu-repo/semantics/article,
This paper presents a unique concentric hexagonal-shaped ring antenna for radio frequency identification (RFID) tags. The rings are excited with a common microstrip feedline. The radiation characteristics of the antenna ...
Experimental assessment of first- and second-life electric vehicle batteries: performance, capacity dispersion, and aging
(IEEE, 2021)
info:eu-repo/semantics/article,
Nowadays, the reuse of electric vehicle batteries is considered to be a feasible alternative to recycling, as it allows them to benefit from their remaining energy capacity and to enlarge their lifetime. Stationary ...
High-isolation antenna array using SIW and realized with a graphene layer for sub-terahertz wireless applications
(Nature Research, 2021)
info:eu-repo/semantics/article,
This paper presents the results of a study on developing an effective technique to increase the performance characteristics of antenna arrays for sub-THz integrated circuit applications. This is essential to compensate the ...
Enabling customizable services for multimodal smart mobility with city-platforms
(IEEE, 2021)
Artículo / Artikulua,
In the last decades, the cities' capacity for generating digital information has grown exponentially. In this context, the successful implementation of smart cities' concept depends on the current possibility of handling ...
Propagation models in vehicular communications
(IEEE, 2021)
info:eu-repo/semantics/article,
In the advent of becoming reality, the era of autonomous vehicles is closer than ever, and with it, the need for faster and reliable wireless connections. The propagation channel determines the performance limits of wireless ...
Liquid level sensor based on dynamic Fabry–Perot interferometers in processed capillary fiber
(Springer Nature, 2021)
info:eu-repo/semantics/article,
In this work, a novel optical fiber sensor capable of measuring both the liquid level and its refractive
index is designed, manufactured and demonstrated through simulations and experimentally. For
this, a silica capillary ...
Single longitudinal mode lasers by using artificially controlled backscattering erbium doped fibers
(IEEE, 2021)
info:eu-repo/semantics/article,
In this work, we propose and experimentally demonstrate a new distributed short linear cavity fiber laser. At one of the cavity ends, fabricated by a commercial femtosecond fiber laser chirped pulse
amplfier, an artificially ...
Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
