Performance analysis of a distributed optical fiber vibration sensor based on a sagnac interferometer
In this work, measuring capabilities of a Sagnac Interferometer-based Distributed Optical Fiber Sensor (DOFS) system are demonstrated by comparing its results to a conventional amplitude-based Distributed Acoustic Sensing ... -
Performance evaluation and interference characterization of wireless sensor networks for complex high-node density scenarios
The uncontainable future development of smart regions, as a set of smart cities’ networks assembled, is directly associated with a growing demand of full interactive and connected ubiquitous smart environments. To achieve ... -
Performance evaluation of spatial modulation patterns in compressive sensing terahertz imaging
Terahertz (THz) imaging traditionally uses pixel-to-pixel mechanical raster scanning, which is slow and limits the resolution and potential applications. Compressive Sensing Terahertz (CS-THz) imaging has the potential to ... -
Perspective chapter: thermal runaway in lithium-ion batteries
Lithium-ion batteries (LIBs) are becoming well established as a key component in the integration of renewable energies and in the development of electric vehicles. Nevertheless, they have a narrow safe operating area with ... -
Phase noise effects on phase-sensitive OTDR sensors using optical pulse compression
We introduce a detailed theoretical, numerical, and experimental study of the effects of laser's phase noise on the performance of phase-sensitive optical time-domain reflectometry (-OTDR) sensors that use optical pulse ... -
Photoisomerization-induced LMR shift for UV radiation detection
(Elsevier, 2024) Artículo / ArtikuluaThis work presents an optical sensor for ultraviolet radiation (UV) detection, based on the combined effects of Lossy Mode Resonance (LMR) in the mid infrared (MIR) spectral region and the photoisomerization of a polymeric ... -

The potential of forecasting in reducing the LCOE in PV plants under ramp-rate restrictions
An increasing number of grid codes are requiring the limitation of the PV output power fluctuation over a given time scale. Batteries represent the most obvious solution to smooth power fluctuations, with the corresponding ... -
Power angle-frequency droop control to enhance transient stability of grid-forming inverters under voltage dips
Due to the replacement of synchronous generators, grid operators are currently demanding to control grid-connected inverters in grid–forming mode to make them participate in the maintenance of the grid. To carry this ... -
Power efficient simple technique to convert a reset-and-hold into a true-sample-and-hold using an auxiliary output stage
A technique to implement true-sample-and-hold circuits that hold the output for almost the entire clock cycle without resetting to zero is introduced, alleviating the slew rate requirement on the op-amp. It is based on a ... -
