Design and operation of nuclear power stations (NPS) are followed by simulation neutron propagation in these stations. It is necessary to consider borders multi-scale structural elements consisting different materials. desirable use parallel computer because big size NPSs. To keep such conditions, algorithms codes for solving the integro-differential transport equation on unstructured grids bei...

‘‘The Journal’s continuing growth has made it necessary for us to be more selective in article acceptance. There must be significant extension of previous acoustical knowledge. One ‘‘just noticeable difference’’ is not enough. Articles must be acoustical, or have a clearly defined relationship to...acoustics. If your initial judgment is that the manuscript obviously does not meet these criteria...

The behaviour of ultrasonic wave propagation through liquid solution has become an important tool for studying physical and chemical properties of liquid solutions. The density, viscosity and ultrasonic velocity of of cholesteryl oleyl carbonate have been studied. From the experimental data various thermo acoustical parameters such as free volume, internal pressure and Rao’s constant and Wada’s...

The long term goal of this research is to develop high-frequency broadband acoustical scattering techniques to remotely and autonomously characterize zooplankton distribution, size, abundance, and community structure, on ecologically relevant spatial and temporal scales. In order to achieve this goal, an autonomous, compact, low-power, high-frequency, broadband acoustical backscattering system ...

Clusters resulting from the deletion of schwa in French are compared with identical underlying clusters in words and pseudowords. Both manual and automatic acoustical comparisons suggest that clusters resulting from schwa deletion in French are highly similar to identical underlying clusters. Furthermore, cluster duration is not longer for clusters resulting from schwa deletion than for identic...
