... that, when predicting the location and level of single- and multi-crack damage on noise-free and noisy data sets, the proposed method is more accurate than the multi-layer perceptron method and multi-layer perceptron by wavelet packet transformation. In addition, the proposed method produces a reasonable...

...J.J. Kollé; L.D. Bibee ABSTRACT Seismometers deployed on the deep ocean floor are subject to significant noise from interfacial seismic waves, currents, surface waves, ships and marine life. This paper describes an autonomous, battery-powered drilling system designed to deploy a seismometer deep...

... be connected with drift divergence or with deformation. This is because any change in the form of an ice cover element must be accompanied by regrouping of Ice floes and their clash if Ice concentration is enough. Dynamic phenomena in ice cover lead to specific acoustic noise under the ice. Knowing...

...C.Y. Liaw ABSTRACT: The "hopping" phenomenon in the phase space of a ship rolling model with two coexisting attractors, representing the heave and heave/roll responses, is investigated. The noise-induced erosion of basins of attraction is studied using the simple cell-to-cell mapping technique...

... have some good characteristics, allowing objective assessment, high-speed judgment, nonhuman error, etc. Therefore, an image processing system allows weld defects to be detected using X-ray radiography in the presence of background noise. This paper deals with an image processing method for detecting...
