Evaluation of a semi-empirical model in predicting erosion–corrosion

Wear, 2009
The phenomenon of erosion–corrosion has been studied extensively by various investigators but no accuratemodel has been developed to predict the interactions between erosion and corrosion.

Semi-empirical modeling of apertures

2003 IEEE International Symposium on Electromagnetic Compatibility, 2003. EMC '03., 2003
A novel method to include models of complex apertures into the finite-difference time-domain method is presented. Instead of resolving the geometrical details of the aperture, the aperture is treated as a magnetic dipole. The properties of the magnetic dipole moment are determined using the measured transmission cross section of the aperture. This semi-

Semi-Empirical Model for SEGR Prediction

IEEE Transactions on Nuclear Science, 2013
The underlying physical mechanisms in single event gate rupture (SEGR) are not known precisely. SEGR is expected to occur when the energy deposition due to a heavy ion strike exceeds a certain threshold simultaneously with sufficient electric field across the gate dielectric.

Semi-empirical models of actinide alloying

Journal of Nuclear Materials, 1999
Abstract Alloys of Np have been studied less than those of the neighboring elements, U and Pu; the higher actinides have received even less attention. Recent interest in 237Np, 241Am and other actinide isotopes as significant, long-lived and highly radiotoxic nuclear waste components, and particularly the roles of metallic materials in new handling ...

Semi-empirical model of solar plages

Science in China Series A: Mathematics, 2001
By use of the 2-m McMath-Pierce telescope at Kitt Peak, the high-quality spectra of a moderate-brightness plage near the center of solar disk were obtained. The data include seven spectral lines: Hα, Hβ, CaII H and K lines and infrared triplet. Under the assumption of plane-parallel atmosphere, the hydrostatic, transfer and statistic equilibrium ...

A semi-empirical model of sunspot umbra

Chinese Astronomy and Astrophysics, 1991
Abstract Based on data obtained with the Kitt Peak Observatory Solar Tower, we have constructed a semi-empirical model of sunspot umbra. Non-LTE calculation was used. The main features are: (1) The temperature structure of the corona and the transition region is similar to the VAL3C quiet sun model.
