A narrowband ultrasonic ranging method for multiple moving sensor nodes द्वारा Ashhar, Karalikkadan, Md. Noor-A-Rahim, Mohammad Omar Khyam, Soh, Cheong Boon

“…We propose a method to measure the range between multiple ultrasonic mobile nodes and static anchors in which we track the Doppler velocity and correct the errors between the transmitted and the received signals due to the Doppler effect. We utilize range-Doppler coupling to estimate the Doppler shift and adjust the range values calculated by correlation. …”

Reflection and scattering from CO₂-laser-produced plasmas द्वारा Hubbard, M, Hubbard, Martin

“…</p> <p>The spectral composition of the backscattered radiation in the region of the fundamental was investigated, and measured spectra were successfully interpreted by considering the stimulated Brillouin scattering process, and the Doppler effect of the expanding plasma corona. In particular, the depen- dence of the parametric growth rate on electron density was investigated by numerical solution of the ion acoustic wave dispersion relation.…”

A domain decomposition technique for generation and scattering of acoustic waves द्वारा Lim, Wei Xian

“…Additionally, implementation of DDT in external flow simulation has eliminated the unsteady perturbation observed in fully nonlinear far-field region and allows proper wave scattering, interference, and Doppler effect to be observed. For 2D viscous flow, a thermal plume under convective flow condition was simulated as a canonical study of thermoacoustic problem. …”

Current limitation in mercury vapour discharges द्वारा Stangeby, P

“…</p> <p>In the positive column at high currents, the neutral velocity distribution is found to be no longer Maxwellian (due to selective ionization of fast particles and of those with long flight paths) which leads to the unusual case of a non-Gaussian radiation absorption profile, although the only broadening influence is that due to the Doppler effect. The resultant profiles are computed and experimental results are presented which substantiate the calculations.…”
