Experimental Study of AM and PM Noise in Cascaded Amplifiers
(MDPI, 2022-02-05)An experimental study of amplitude modulation (AM) and phase modulation (PM) noise spectra in cascaded amplifiers was carried out as a function of the number of amplification stages and the input power. Flicker and white ... -
Experimental study of the isotope effect of the permeability in structural steels for fusion reactors: Eurofer and SS316
(Elsevier, 2024-03)The transport of hydrogen isotopes through the elements that make up a fusion reactor, and their corresponding interaction with these materials, have a direct impact on its operation. Consequently, it is essential to master ... -
Experimental Study of the Response of Efficient Lighting Technologies to Complex Voltage Fluctuations
(Elsevier, 2014-07-09)The replacement of incandescent lamps with more energy-efficient lighting technologies has a direct influence on the way flicker is measured. The International Electrotechnical Commission (IEC) established in the 61000-4-15 ... -
Experimental Study of the Summation of Flicker Caused by Wind Turbines
(MDPI, 2019-06-22)Integration of wind energy into the grid faces a great challenge regarding power quality. The International Electrotechnical Commission (IEC) 61400-21 standard defines the electrical characteristics that need to be assessed ... -
Experimental study on the thermal control of a roof-top collective building antenna using a porous matrix filled with Water-Copper nanofluid
(Elsevier, 2022-04)This experimental work addressed the thermal control a roof-top collective building antenna meant to control home equipment in smart buildings. The antenna was placed inside a concentric quasi-cylindrical cavity maintained ... -
Experimental test of a hypothesized diachronic change in Basque accentuation
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2006)In the central and western Basque-speaking regions there are two main accentual types: In the Northern Bizkaian area we find a pitch-accent system with demarcative phrase-initial rises and uniformly falling (H*L) accents, ... -
