TIME DOMAIN BROADBAND NOISE PREDICTIONS FOR NON-CAVITATING MARINE PROPELLERS WITH WALL PRESSURE SPECTRUM MODELS

Time domain broadband noise predictions for non-cavitating marine propellers with wall pressure spectrum models

The broadband noise can be dominant or important for total characteristics for marine propeller noise representing the minimum base of self-noise.Accurate prediction of such noise is crucial for survivability of underwater military vessels.While the FW-H Formulation 1B can be used to predict broadband trailing edge noise, the method required experi

Analysis of Cementum Layers in Archaeological Material

The aim of this study was to assess the utility of cementum layers for estimating age at death of remains from an archaeological site.Variability in cementum layer counts due to interobserver error and variation among dental regions were analyzed.Interobserver error was later incorporated into age ranges based on counts of cementum layers and compa
