Semi-empirical models of actinide alloying
Journal of Nuclear Materials, 1999Abstract 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, 2001By 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, 1991Abstract 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.

SMOS Semi-Empirical Ocean Forward Model Adjustment
IEEE Transactions on Geoscience and Remote Sensing, 2012A prerequisite for the successful retrieval of geophysical parameters from remote sensing measurements is the development of an accurate forward model. The European Space Agency Soil Moisture and Ocean Salinity (SMOS), carrying onboard an L-band interferometric radiometer (Microwave Interferometric Radiometer using Aperture Synthesis), was launched on ...

A L-band semi-empirical ocean backscattering model
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017A semi-empirical model is proposed by merging an improved directional spectrum into the advanced integral equation method (AIEM) in this paper. By establishing a new angular spreading function (ASF), this improved directional spectrum provides a better description of wave directionality, especially over wavenumber range from short-gravity waves to ...

Semi-Empirical Model of Strong Evaporation
2017Knowledge of laws of strong evaporation is instrumental for the solution of a number of applied problems: the effect of laser radiation on materials (Gusarov and Smurov in Phys. Fluids 14:4242–4255, [1]), calculation of the parameters of discharge into vacuum of a flashing coolant (Larina et al. in Fluid Dyn. 31:127–133, [2]), etc.

A semi-empirical model for maximal LINPACK performance predictions
Sixth IEEE International Symposium on Cluster Computing and the Grid (CCGRID'06), 2006In general, the maximal LINPACK performance of a large cluster depends on the number of processors, the total memory capacities, the problem size, the block size, the middle-ware of message passing, and the BLAS (basic linear algebra subprograms) library. One must handle these multi-variables factors to predict the performance score.

Semi-Empirical Process Modeling: Model and Database Integration
CAE and Intelligent Processing of Polymeric Materials, 1997Abstract Process modeling has been successfully used in the plastics injection molding industry over the past decade. However, mathematical descriptions in certain areas of plastics processing are either not very well understood or are too complicated to be formulated.

A New Semi-empirical Model for the Analysis of Surface Roughness Heterogeneity
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006The use of a theoretical backscatter model to analyse medium to low spatial resolution microwave data is still very complicated, particularly because of the difficulty in defining a unique roughness parameter, capable of adequately representing heterogeneous terrain.

Semi-empirical model for intense evaporation
Thermophysics and Aeromechanics, 2017A semi-empirical model based on the linear kinetic theory was developed for intense evaporation. The extrapolated drops for pressure and temperature at the condensed phase surface were calculated through summing of linear and squared terms. The analytical dependencies were obtained for gas parameters in gas-dynamic zone as functions of Mach number ...
