Range–Angle Transceiver Beamforming Based on Semicircular-FDA Scheme

IEEE Transactions on Aerospace and Electronic Systems, 2022
Incontrast to the steady angle-dependent transmit beampattern of the conventional phased array, the counterpart of a frequency diverse array (FDA) is basically time variant and range–angle coupled, which limits its potential application in many scenarios.

Experimental investigation of buoyancy effects on local heat transfer of supercritical pressure CO2 in horizontal semicircular tube

International Journal of Heat and Mass Transfer, 2021
To estimate the characteristics of local heat transfer in the channel of a printed circuit heat exchanger (PCHE), a semicircular channel (tube) was manufactured to replicate the channel shape of the PCHE.

Semicircular Flap Revisited

Archives of Ophthalmology, 1986
The semicircular flap of Tenzel has proved to be an excellent reconstructive procedure for central eyelid defects. Although originally described for defects measuring half of the eyelid, we have found that it may be used for defects greater than 60% in the lower eyelid, if the lower eyelid retractors and inferior orbital septum are identified and ...

Investigation on local convection heat transfer of supercritical CO2 during cooling in horizontal semicircular channels of printed circuit heat exchanger

Applied Thermal Engineering, 2019
The local heat transfer characteristics of supercritical CO2 flowing in horizontal semicircular straight channel of the printed circuit heat exchanger (PCHE) geometries during cooling under forced and mixed convection conditions have been numerically ...

Magneto-nanofluidic thermal transport and irreversibility in semicircular systems with heated wavy bottom under constant fluid volume and cooling surface constraints

International Journal of Numerical Methods for Heat & Fluid Flow
Purpose This study aims to investigate the influence of wall curvature in a semicircular thermal annular system on magneto-nanofluidic flow, heat transfer and entropy generation.

Lateral Semicircular Canal Dehiscence

Otology & Neurotology, 2007
genesis of these symptoms has been attributed to the presence of a third window, which provides a different path for the dissipation of acoustic energy (4). A subset of patients, however, are asymptomatic, and these patients’ conditions are diagnosed on imaging or postmortem analyses of temporal bones.
