Corner reflectors form the major scattering centers in the radar signatures of ships, aircraft and vehicles. The radar cross section (RCS) reduction of these "flare spots" (corner reflectors) plays an ...

Objective To analyse caesarean section (CS) using Robson 10-group classification system in an Ethiopian university hospital. Design Cross-sectional study. Setting A university hospital in eastern, ...

Researchers from the National University of Singapore (NUS) have achieved exciting progress in quantum metrology, a field ...

In this letter, we present a graphical method based on Green's analysis of scattering antennas to optimize the load impedances for achieving maximum modulated radar cross-section (RCS) of ...

While cross-sections with recessed corners showed zones of recirculation at the frontal and backward corners. The present results indicated that cross-sections with corner modifications create larger ...

This work aims to investigate the transverse free vibration of non-uniform beams with exponentially varying rectangular and circular cross-sections. When solving the governing equations for ...

Structures for lossless ion manipulation-based high-resolution ion mobility (HRIM) interfaced with mass spectrometry has emerged as a powerful tool for the separation and analysis of many isomeric ...
