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 ...
Wavelength and intensity based lossy mode resonance breathing sensor
(Elsevier, 2021)
info:eu-repo/semantics/article,
Copper oxide (CuO) allows the generation of lossy mode resonance (LMR) in a wide wavelength range of the optical spectrum, both in the visible and the near-infrared (NIR). For this, it is necessary to use a configuration ...
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 ...
Optimal strain-gauge placement for mechanical load estimation in circular cross-section shafts
(Elsevier, 2021)
Artículo / Artikulua,
The customary electrical circuit configuration for estimating mechanical loads with strain gauges uses Wheatstone full- or half-bridges. For each mechanical load to be estimated, a dedicated bridge with two or four gauges
has ...
A metasurface-based single-layered compact AMC-backed dual-band antenna for off-body IoT devices
(IEEE, 2021)
info:eu-repo/semantics/article,
In this article, a compact printed monopole dual-band antenna using artificial magnetic conductor (AMC)-plane with improved gain and broader bandwidth, applicable for off-body internet of things (IoT) devices is presented. ...
Empirical and modeling approach for environmental indoor RF-EMF assessment in complex high-node density scenarios: public shopping malls case study
(IEEE, 2021)
Artículo / Artikulua,
This work provides an intensive and comprehensive in-depth study from an empirical and modeling approach of the environmental radiofrequency electromagnetic fields (RF-EMF) radiation exposure in public shopping malls, as ...
Corrosion behavior in volcanic soils: in search of candidate materials for thermoelectric devices
(MDPI, 2021)
info:eu-repo/semantics/article,
Thermoelectric generators have emerged as an excellent solution for the energy supply of volcanic monitoring stations due to their compactness and continuous power generation. Nevertheless, in order to become a completely ...
Hybrid Raman‑erbium random fiber laser with a half open cavity assisted by artificially controlled backscattering fiber refectors
(Springer Nature, 2021)
Artículo / Artikulua,
A hybrid Raman-erbium random fber laser with a half-open cavity assisted by chirped artifcially
controlled backscattering fber refectors is presented. A combination of a 2.4 km-long dispersion
compensating fber with two ...
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 ...
Energy-efficient amplifiers based on quasi-floating gate techniques
(MDPI, 2021)
Artículo / Artikulua,
Energy efficiency is a key requirement in the design of amplifiers for modern wireless applications. The use of quasi-floating gate (QFG) transistors is a very convenient approach to achieve such energy efficiency. We ...
