Sound absorption by clamped poroelastic plates [PDF]
Measurements and predictions have been made of the absorption coefficient and the surface acoustic impedance of poroelastic plates clamped in a large impedance tube and separated from the rigid termination by an air gap.

Moisture transport in the ventilated channel with heating by coil [PDF]
This article considers the moisture transport phenomenon in the vertical ventilated channel. HVF construction parameters are determined influencing the rate of moisture transport. It is necessary to have h ≤ L/25 ≈ 8 cm.

Research on a fault current limiter based on variable reactor
With the increase of the power load in power grid, the short circuit level continues to rise, and excessive short-circuit current will do great damage to power equipment and imperil power systems.

Photonic band gap in isotropic hyperuniform disordered solids with low dielectric contrast [PDF]
We report the first experimental demonstration of a TE-polarization photonic band gap (PBG) in a 2D isotropic hyperuniform disordered solid (HUDS) made of dielectric media with a index contrast of 1.6:1, very low for PBG formation.

Measuring Transducer for Air Gap Capacitive Sensor in Hydrogenerator
One of the most important parameters of powerful hydro generators (HG) is the air gap between the rotor and the stator, and its deviation from the set norms is a defect that can lead to serious accidents.

Full-Scale Experiments of Water-Mist Systems for Control and Suppression of Sauna Fires
Sauna is a common fixture in many facilities; a specific fire-protection system is typically designed and installed for this application, as short circuits or direct contact with incandescent materials may result in a fire.

The air gap between tape and drum in a video recorder [PDF]
Lubrication with ambient air is not quite generally applied. The best known application is the "oil bearing" in tape recording systems for audio, video and computer applications; where the gap height that is needed for effective lubrication may quite ...

Impact of 3D air gap eccentricity on winding insulation temperature characteristic in PMSG
The static air gap eccentricity is one of the prevalent faults in permanent magnet synchronous generators. In previous studies, the variation of magnetic flux density, stator current and vibration have been studied mostly.
