Common-mode and phase-to-ground voltage reduction in back-to-back power converters with discontinuous PWM
(IEEE, 2020)
info:eu-repo/semantics/article,
Discontinuous space vector pulsewidth modulation (DSVPWM) techniques are an interesting option for three-phase, two-level power converters when efficiency is a key factor. Such is the case of back-to-back (B2B) power ...
A comprehensive survey of 'metamaterial transmission-line based antennas: design, challenges, and applications'
(IEEE, 2020)
info:eu-repo/semantics/article,
In this review paper, a comprehensive study on the concept, theory, and applications of composite right/left-handed transmission lines (CRLH-TLs) by considering their use in antenna system designs have been provided. It ...
Experimental assessment of cycling ageing of lithium-ion second-life batteries from electric vehicles
(Elsevier, 2020)
info:eu-repo/semantics/article,
The reutilization of batteries from electric vehicles allows to benefit from their remaining energy capacity and to increase their lifespan. The applications considered for the second life of these batteries are less ...
Fundamental radiative processes in near-zero-index media of various dimensionalities
(American Chemical Society, 2020)
info:eu-repo/semantics/article,
Spontaneous emission, stimulated emission and absorption are the three fundamental radiative processes describing light-matter interactions. Here, we theoretically study the behavior of these fundamental processes inside ...
High-power filter design in waveguide technology: future generation of waveguide satellite filters in payloads handling increasing bit rates and numbers of channels
(IEEE, 2020)
info:eu-repo/semantics/article,
To design a filter for a particular application, many issues must first be considered. Which technology will be the most convenient? What design technique will provide better results for a particular set of frequency ...
Electric discharge detection and localization using a distributed optical fiber vibration sensor
(Elsevier, 2020)
info:eu-repo/semantics/article,
Partial discharges are a type of electric discharge that cause localized breakdowns in a small portion of an insulating material without forming a complete rupture. In high power electric machines as well as in transmission ...
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
(MDPI, 2020)
Artículo / Artikulua,
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ...
A review of IoT sensing applications and challenges using RFID and wireless sensor networks
(MDPI, 2020)
info:eu-repo/semantics/article,
Radio frequency identification (RFID) and wireless sensors networks (WSNs) are two fundamental pillars that enable the Internet of Things (IoT). RFID systems are able to identify and track devices, whilst WSNs cooperate ...
NATRA: Network ACK-Based Traffic Reduction Algorithm
(IEEE, 2020)
info:eu-repo/semantics/article,
Traffic monitoring involves packet capturing and processing at a very high rate of packets per second. Typically, flow records are generated from the packet traffic, such as TCP flow records that feature the number of bytes ...
A comprehensive review: materials for the fabrication of optical fiber refractometers based on lossy mode resonance
(MDPI, 2020)
info:eu-repo/semantics/article,
Lossy mode resonance based sensors have been extensively studied in recent years. The versatility of the lossy mode resonance phenomenon has led to the development of sensors based on different configurations that make use ...
