The complex morphology of an insect campaniform sensillum is responsible for transforming strains of the integument into a displacement of the campaniform dome and subsequently a deformation of the dendritic membrane. In this paper, the first step in this coupling process was investigated in identified campaniform sensilla on the wing of the blowfly by stimulating the sensilla with chord-wise d...

The extremely altered topmost surface layer, known as the white formed in a medium-carbon low-alloy steel result of impacts by angular 10–12 mm granite particles during slurry erosion process is comprehensively investigated. For this purpose, characteristics, morphology, and formation mechanism layer are described based on microstructural observations using optical, scanning transmission electr...

Wave diffraction is a very important phenomenon in marine engineering and several models have been developed for its simulation. The new version of SWAN, a third generation spectral model, includes an approximation to wave diffraction. The approximation is based on the mild-slope equation for refraction and diffraction, omitting phase information. The objective this paper is to evaluate the per...

This research intends to develop a method based on the Artificial Neural Network (ANN) to predict permanent earthquake-induced deformation of the earth dams and embankments. For this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. In order to predict earthquake-induced deformation o...

We report the surprising observation of directional tunneling escape from nearly spherical fused-silica optical resonators, in which most of the phase space is filled with nonchaotic regular trajectories. Experimental and theoretical studies of the dependence of the far-field emission pattern on both the degree of deformation and the excitation condition show that nonperturbative phase-space st...

1 Modern hearing aid technology allows the response pattern of a multi-microphone directional array to be varied in response to the acoustic environment. For example, some systems attempt to identify noise sources and respond by steering an acoustic null or nulls formed by the directional microphones toward the noise source. While this technology holds the promise of improved speech intelligibi...

The paper analyses possibilities of episodic multi-winner multi-directional associative memory taught by evolutionary algorithm. This kind of memory allows to store and recall more complex associations, like episode-to-episode.
