Hand-as-a-prop: using the hand as a haptic proxy for manipulation in virtual reality
Haptic feedback can be almost as important as visual information in virtual reality environments. On the one hand, in Active Haptic Feedback, specialized devices such as vibrotactile gloves are employed; however, these ... -
Health indicator selection for state of health estimation of second-life lithium-ion batteries under extended ageing
Nowadays, the economic viability of second-life (SL) Li-ion batteries from electric vehicles is still uncertain. Degradation assessment optimization is key to reduce costs in SL market not only at the repurposing stage, ... -
Heat pipes thermal performance for a reversible thermoelectric cooler-heat pump for a nZEB
The nZEB standards reduce the energy demand of these buildings to a minimum, obtaining this little energy from renewable resources. Taking these aspect into consideration, a thermoelectric cooler-heat pump is proposed to ... -
Hg2+ optical fiber sensor based on LSPR generated by gold nanoparticles embedded in LBL nano-assembled coatings
Mercury is an important contaminant since it is accumulated in the body of living beings, and very small concentrations are very dangerous in the long term. This paper reports the fabrication of a highly sensitive fiber ... -
High aperture efficiency wide corrugations bull’s-eye antenna working at 60 GHz
A full metallic Bull’s-Eye (BE) antenna operating at 60 GHz is numerically and experimentally analyzed. The antenna presents wide grooves, rather than narrow ones, which support higher order resonances that lead to a large ... -
High frequency vibration sensor using a fiber laser with a multicore fiber interferometer
We present an interferometric vibration sensor that uses three-core fibers. The transducer is constructed by splicing a segment 20 mm long of a multicore optical fiber (MCF) to a single-mode optical fiber (SMF). The end ... -
High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems
An innovative of-chip antenna (OCA) is presented that exhibits high gain and efciency performance at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented on stacked silicon layers ... -
High performance antenna-on-chip inspired by SIW and metasurface technologies for THz band operation
In this paper, a high-performance antenna-on-chip (AoC) is implemented on gallium arsenide (GaAs) wafer based on the substrate integrated waveguide (SIW) and metasurface (MTS) technologies for terahertz band applications. ... -
High performance fiber laser resonator for dual band (C and L) sensing
This work presents an experimental analysis and comparison of the performance of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror both in C- and L-band. Single-wavelength emission ... -
High sensitive and selective C-reactive protein detection by means of lossy mode resonance based optical fiber devices
This work presents the development of high sensitive, selective, fast and reusable C-reactive protein (CRP) aptasensors. This novel approach takes advantage of the utilization of high sensitive refractometers based on ... -
High sensitivity humidity sensor based on cladding-etched optical fiber and lossy mode resonances
In this work a high sensitivity optical fiber humidity sensor (OFHS) is presented. The configuration chosen for this purpose is a cladding-etched single mode optical fiber (CE-SMF) coated with a thin film of tin oxide ... -
High sensitivity lossy-mode resonance refractometer using low refractive index PFA planar waveguide
In this work a new strategy to improve the sensitivity of refractometers based on lossy-mode resonances has been proved. The proximity of the PFA (tetrafluoroethylene-perfluoro polymer) substrate refractive index to that ... -

This paper presents the results of a study on developing an effective technique to increase the performance characteristics of antenna arrays for sub-THz integrated circuit applications. This is essential to compensate the ... -
Highly sensitive sensor for measuring material thermal expansion using a ring laser
A new thermal expansion sensor is presented in this letter. It combines an interferometric fiber sensor and an erbium-doped fiber ring laser as the light source. The sensor consists of a combination of single-mode, ... -
HIL flight simulator for VTOL-UAV pilot training using X-plane
With the increasing popularity of vertical take-off and landing unmanned aerial vehicles (VTOL UAVs), a new problem arises: pilot training. Most conventional pilot training simulators are designed for full-scale aircrafts, ... -
A historical account of types of fuzzy sets and their relationships
In this work we review the definition and basic properties of the different types of fuzzy sets that have appeared up to now in the literature. We also analyze the relationships between them and enumerate some of the ... -
Hospital preparedness during epidemics using simulation: the case of COVID-19
This paper presents a discrete event simulation model to support decision-making for the short-term planning of hospital resource needs, especially Intensive Care Unit (ICU) beds, to cope with outbreaks, such as the COVID-19 ... -
