On designing an optimum sonar window

Design of an optimum wideband active sonar array with robustness

The use of wideband active sonar array processing to estimate the range, velocity and bearing of a target has received much interest in the literature recently. Although increased attention has been focused on wideband correlation processing for estimating range and velocity, array directivity patterns are almost always computed and interpreted under the narrowband signal assumption. This paper...

Energy window setting for optimum Tl-201 cardiac imaging [Persian]

  Introduction: Poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. Scattered photons are the main cause of degrading the contrast and resolution in SPECT imaging that result in error in quantification. Thallium decay is ve...

Designing Magnetic Components for Optimum Performance Article

Assuming that the reader is familiar with basic magnetic design theory, this topic provides design guidance to achieve high efficiency, low electromagnetic interference (EMI), and manufacturing ease for the magnetic components in typical offline power converters. Magnetic-component designs for a 90-W notebook adapter and a 300-W ATX power supply are used as examples. Magnetic applications to be...

Intelligent Algorithm for Optimum Solutions Based on the Principles of Bat Sonar

This paper presents a new intelligent algorithm that can solve the problems of finding the optimum solution in the state space among which the desired solution resides. The algorithm mimics the principles of bat sonar in finding its targets. The algorithm introduces three search approaches. The first search approach considers a single sonar unit (SSU) with a fixed beam length and a single start...
