Experimental evaluation of distortion in amplitude modulation techniques for parametric loudspeakers
Parametric loudspeakers can generate a highly directional beam of sound, having applications in targeted audio delivery. Audible sound modulated into an ultrasonic carrier will get self-demodulated along the highly directive ... -
Experimental evidence of coherence resonance in a time-delayed bistable system
We report on the experimental observation of coherence resonance in a bistable system with delay. Our system consists of a vertical-cavity surface-emitting laser subject to time-delayed optical feedback simultaneously from ... -
Experimental evidence of the viability of thermoelectric generators to power volcanic monitoring stations
Although there is an important lack of commercial thermoelectric applications mainly due to their low efficiency, there exist some cases in which thermoelectric generators are the best option thanks to their well-known ... -
Experimental evidence that rill-bed morphology is governed by emergent nonlinear spatial dynamics
Past experimental work found that rill erosion occurs mainly during rill formation in response to feedback between rill-flow hydraulics and rill-bed roughness, and that this feedback mechanism shapes rill beds into a ... -
Experimental investigation of flame flashback in a swirl burner by means of planar laser-induced fluorescence

Experimental investigation of the applicability of a thermoelectric generator to recover waste heat from a combustion chamber
A thermoelectric generator prototype has been built; it produces 21.56 W of net power, the produced thermoelectric power minus the consumption of the auxiliary equipment, using an area of 0.25 m2 (approximately 100 W/m2). ... -
Experimental investigation of the particle oscillation instability in a single-axis acoustic levitator
Single-axis acoustic levitators are employed in biomedicine, chemistry and physics experiments due to their ability to trap in mid-air objects of a wide range of materials and sizes. Although this type of levitator has ... -

Experimental polymorphism survey in intergenic regions of the icaADBCR locus in Staphylococcus aureus isolates from periprosthetic joint infections
Staphylococcus aureus is a leading cause of prosthetic joint infections (PJI) characterized by bacterial biofilm formation and recalcitrance to immune-mediated clearance and antibiotics. The molecular events behind PJI ... -
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
The terahertz band has been historically hindered by the lack of efficient generators and detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz gap.” A rapid development of terahertz ... -
