Semi-Empirical Model of Droplet Size Distribution From the Maximum Entropy Principle in Sodium Spray
Frontiers in Energy Research, 2022 When a sodium leakage accident occurs in the sodium-cooled fast reactor, the leaked sodium reacts violently with the air in the form of droplets, resulting in the phenomenon of sodium spray fire.

Parameter estimation for empirical and semi-empirical models in a direct ethanol fuel cell
Energy Reports, 2023 Experimental data from a Direct Ethanol Fuel Cell (DEFC) provides a general perspective about its performance; nevertheless, it does not provide information about the cell’s physical characteristics nor information to improve its performance.

Development of semi-empirical model for radiochemical reactions [PDF]
Journal of Korean Medical Science, 2001 A mathematical model, which represents the radio-chemical reactions in water, was developed to study the effect of the radio-chemical products on cell killing. The five differential equations were solved using dose rate equation and cell survival as a function of dose was computed.

Semi–Empirical Model of the Simulation of Traffic Pollution Dispersion Near Roadways
The Baltic Journal of Road and Bridge Engineering, 2011 A semi-empirical statistical model based on physical processes intended for simulation of traffic pollution dispersion near roadways is applied. The pollution source is a road and transport, which in this model is simulated as an undeviating cut-off ...

Semi-Empirical Model for Nano-Scale Device Simulations [PDF]
, 2010 We present a new semi-empirical model for calculating electron transport in atomic-scale devices. The model is an extension of the Extended H\"uckel method with a self-consistent Hartree potential. This potential models the effect of an external bias and

Electron density in the F1 layer over Norilsk in 2007–2014
Solar-Terrestrial Physics, 2019 We report the results of the analysis of annual variations in daily electron density (N) for various solar activity conditions — minimum, rise, and maximum (2007–2014) — obtained from digisonde measurements at the ionospheric station Norilsk (69.4° N, 88.

Semi-empirical Model of Global Exposure using Stochastic Geometry [PDF]
2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021 Exposure to electromagnetic fields due to cellular networks in an urban environment is studied using stochastic geometry. We describe a simple but functional and realistic semi-empirical model based on the modeling of base station patterns as Poisson Point Processes and applied to two Brussels municipalities.

Quantifying the performance of a top-down natural ventilation Windcatcher™ [PDF]
, 2009 Estimating the performance of a natural ventilation system is very important if one is to correctly size the system for a particular application. Estimating the performance of a Windcatcher™ is complicated by the complex flow patterns that occur during ...
