Abstract Dielectric properties of dislocation-free hoar-frost ice crystals were measured in the audio-frequency range. Anomalously small relaxation strength was found in the dislocation-free area of the crystal samples while dislocations deliberately introduced by scratching the samples drastically modified the relaxation strength. Since measurements made in the area of high dislocation density indicated normal behavior, electrically charged dislocations are considered to be the source of the normally observed dielectric relaxation.

This paper indicates how vibration responses of a vehicle body produced by inputs at the rear wheels were modelled using a mobility matrix coupling method. The model simulates the multiple coupling of the sub-assemblies comprising the rear axle, rear suspension and vehicle body in the lower audio-frequency range. Such a model is useful when investigating the transmission paths along which vibrations travel into the vehicle body, subsequently generating internal noise.
