High‐intensity Effects in the Parametric Transmitting Array

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Design and Implementation of a Monopulse Sonar Transmitting Array

Robust approaches to remote calibration of a transmitting array

We consider the problem of estimating the gains and phases of the RF channels of a M-element transmitting array, based on a calibration procedure where M orthogonal signals are sent through M orthogonal beams and received on a single antenna. The received data vector obeys a linear model of the type y 1⁄4 AFg þ n where A is an unknown complex scalar accounting for propagation loss and g is the ...

On Demand Parametric Array Dataflow Analysis

We present a novel approach for exact array dataflow anal-ysis in the presence of constructs that are not static affine.The approach is similar to that of fuzzy array dataflow anal-ysis in that it also introduces parameters that represent in-formation that is only available at run-time, but the pa-rameters have a different meaning and are analyzed beforethey are introduc...

A multimode electromechanical parametric resonator array

Electromechanical resonators have emerged as a versatile platform in which detectors with unprecedented sensitivities and quantum mechanics in a macroscopic context can be developed. These schemes invariably utilise a single resonator but increasingly the concept of an array of electromechanical resonators is promising a wealth of new possibilities. In spite of this, experimental realisations o...
