Semi-Empirical Process Modeling: Model and Database Integration

CAE and Intelligent Processing of Polymeric Materials, 1997
Abstract 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.

Semi-empirical model for intense evaporation

Thermophysics and Aeromechanics, 2017
A 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 ...

Semi-Empirical Model of Strong Evaporation

2017
Knowledge 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 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.

Semi-Empirical Hamiltonian Model for Elliptical Cavities

2018
We propose to use the sum of TM_{0m0} modes to treat a radio-frequency superconducting elliptical cavity as a pill-box cavity with variable radius. The amplitudes of the different modes are obtained interpolating the field-map of the cavity with the model.

Semi-empirical model for helical magnetocumulative generators

IEEE Conference Record - Abstracts. PPPS-2001 Pulsed Power Plasma Science 2001. 28th IEEE International Conference on Plasma Science and 13th IEEE International Pulsed Power Conference (Cat. No.01CH37, 2001
Summary form only given. A semi-empirical model of a helical magnetocumulative generator (MCG) has been developed with a single adjustable variable (called the characteristic time) that describes the time dependent changes in the output current of these generators. A brief description of this model and the characteristic time will be presented.

Secondary Electron Spectra: A Semi-Empirical Model

Radiation Protection Dosimetry, 1985
A model based on evaluation of coefficients in Bethe's asymptotic expansion of the first Born approximation has been developed to extend the data base of differential ionization cross sections needed in track structure calculations. The coefficient of the lowest-order term in this expansion is related to the photoionization cross section of the target,

Semi-empirical Modelling of Hydrogen Sorption Isotherms

2021
Solid-state hydrogen storage is the key to environmentally-friendly fuel economy. Several reports have demonstrated adsorption within micropores can densify hydrogen past the solid phase [1] moving the field closer to practical hydrogen storage. However, determination of adsorbate hydrogen density is difficult, expensive and time-consuming.

The semi-empirical thermosphere model DTM2013

2014
Atmospheric density models are used in satellite orbit determination and prediction programs to compute the atmospheric drag force, as well as in upper atmosphere studies. They represent temperature and (partial) density as a function of altitude, latitude, local solar time, day-of-year, and parameters related to the state of atmospheric heating due to

Shell-model semi-empirical nuclear masses (I)

Nuclear Physics, 1965
Abstract The 1961 Nucleidic Mass Table has been revised by a least-squares adjustment including newer experimental data. Differences of nuclear masses were plotted as functions of N and Z, revealing shell and other structure effects. The information obtained form these graphs was used to construct a generalized shell model mass formula, representing ...
