Semi-empirical Haken–Strobl model for molecular spin qubits
New Journal of Physics, 2023 Understanding the physical processes that determine the relaxation T _1 and dephasing T _2 times of molecular spin qubits is critical for envisioned applications in quantum metrology and information processing.

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.

A SEMI-EMPIRICAL MODEL TO PREDICT DIESEL ENGINE COMBUSTION PARAMETERS [PDF]
Journal of Mechanical Engineering and Sciences, 2013 To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved.

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.

A Semi-Empirical Model for Predicting Frost Properties [PDF]
Processes, 2021 In this study, a quantitative method for classifying the frost geometry is first proposed to substantiate a numerical model in predicting frost properties like density, thickness, and thermal conductivity. This method can recognize the crystal shape via linear programming of the existing map for frost morphology.

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 ...

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.
