f-HybridMem: a consensual analysis via fuzzy consensus measures and penalty functions
This paper considers the consensual analysis in decision-making (CDM) processes based on fuzzy logic (FL) and interval-valued fuzzy logic (IVFL), providing a CDM-strategy, by exploring the axiomatic properties of fuzzy ... -
Fabrication of long period gratings by periodically removing the coating of cladding-etched single mode optical fiber towards optical fiber sensor development
Here, we present a novel method to fabricate long period gratings using standard single mode optical fibers (SMF). These optical devices were fabricated in a three-step process, which consisted of etching the SMF, then ... -
A family of alternating current amplifiers for ultra-low frequency operation
A family of capacitively coupled alternating current (AC) amplifiers featuring ultra-low (below 1 Hz) corner frequency is presented. This is achieved by using high-gain devices which actively boost feedback resistance and ... -
Far-field and near-field physics of extraordinary THz transmitting hole-array antennas
Despite three decades of effort, predicting accurately extraordinary transmission through subwavelength hole arrays has proven challenging. The lack of quantitative design and modeling capability to take into account ... -
Fast and robust ellipse detection algorithm for head-mounted eye tracking systems
In head-mounted eye tracking systems, the correct detection of pupil position is a key factor in estimating gaze direction. However, this is a challenging issue when the videos are recorded in real-world conditions, due ... -
Fast capacity and internal resistance estimation method for second-life batteries from electric vehicles
The success of second-life (SL) Li-ion batteries from electric vehicles is still conditioned by their technical and economic viability. The knowledge of the internal parameters of retired batteries at the repurposing stage ... -
Fault detection of planetary gears based on signal space constellations
A new method to process the vibration signal acquired by an accelerometer placed in a planetary gearbox housing is proposed, which is useful to detect potential faults. The method is based on the phenomenological model and ... -
FDTD and empirical exploration of human body and UWB radiation interaction on TOF ranging
In time-of-flight (TOF)-based human ranging systems, target sensors are often mounted on or close to the human body, which may raise non-line-of-sight (NLOS) cases and lead to significant ranging errors depending on the ... -
Femtosecond laser inscription of diffraction gratings in CYTOP fibers for optical fiber sensing
The use of the new CYTOP fibers for the inscription of optical structures and the sensing of different parameters has started to gain importance in the last decade. This work presents the design and manufacture of a CYTOP ... -
