Neural network recognition of features the fluorescence spectrum a thermosensitive probe is exploited in order to achieve fluorescence-based thermometry with an accuracy 200 mK 100 MHz bandwidth, and high robustness against fluctuations laser intensity used. The concept implemented on rhodamine B dyed mixture copper chloride glycerol, temperature dependent investigated range between 234 K 311 K. spatial dependence calibrated amplitude phase photothermally induced oscillations along axis...
This article presents a perceptual comparison of the loudness large range 64 different typical "living room" sounds transmitted through two walls: (1) light-weight wall, composed gypsum boards mounted on metal "C" studs and (2) heavy-weight built out lime sand bricks plastered one side.The walls had (laboratory measured) sound insulation spectra, but their Rw + C50-5000 rating was same: 52 dB.Compared to massspring-mass-type wall better properties in middle frequency worse at low frequencies...
Lorentz-force-induced vibrations in MRI systems cause significant acoustic noise levels during scanning, the main source being vibrating gradient coil. In this paper, a novel active vibration control technique is presented to reduce of coil, and hence, achieve reduction scanning. The uses seismic masses that are actuated by means piezo actuators create forces on coil counteracting its vibrations. Using four mass actuators, 3-8 dB at resonance frequencies achieved, giving an overall 3 for...
Although near-field acoustic holography (NAH) is recognized as a powerful and extremely fast imaging method based on the inverse solution of wave-equation, its practical implementation has suffered from problems with use discrete Fourier transformation (DFT) in combination small aperture sizes windowing. In this paper, presented that extrapolates finite spatial before DFT applied, which impulse response information known data. The developed called linear predictive border-padding an...
Due to the demand for higher accuracy and lower acoustic noise levels, there is a growing interest active vibration suppression in industrial application. Many control concepts have been proposed this field that are suited introduce damping systems with large number of modes. However, tuning often focussed on reduction one dominant mode. Such approaches less transparent when several modes involved. A combined loop-shaping root-locus approach reduce low-order controllers. The experimentally...
With the world facing urgency of energy transition, development efficient and quiet electrical infrastructures is topical importance in construction environment future. The problem noise from power distribution systems often underestimated, although several works literature underline effect disturbance on population, especially concerning low frequency range. This paper overviews issue low-frequency generated by substations, experimental characterization source to possible mitigation...
Lightweight floor structures, such as timber or hybrid floors, face challenges associated with excessive vibrations and elevated levels of low-frequency impact sound. Especially here, accurate prediction a floor’s vibration acoustic behavior is essential. However, typical laboratory testing building elements costly time-consuming. To reduce costs, in this study, adapted simulations are carried out on two types steel-timber structures to evaluate The made laminated veneer lumber the top...
