Identifying atmospheric pollutant sources using a machine …
Estimating the sources of contaminant or hazard emissions is important for pollution control and safety management. Markov chain Monte Carlo (MCMC), combined with Bayesian inference, was used to identify the source terms of pollutants. However, the efficiency and accuracy of the forward dispersion model greatly impacted the …

Machine learning based quantitative consequence …
Apart from PHAST UDM, although there are machine learning based models that are constructed for toxic gas dispersion (Ma and Zhang, 2016; Ni et al., 2020; Qian et al., 2019; Wang et al., 2015, 2018), none of other dispersion models effectively complete this task. Therefore, there is a need for a widely applicable fast prediction model for toxic ...

Measures of Dispersion – Machine Learning Geek
The simplest measure of dispersion is Range; it is the difference between the highest value and lowest value in the dataset. It offers a crude insight into the spread of the data, but very susceptible to outliers. The range is helpful when you want to focus on extreme values in the dataset. The formula of Range is:
Fundamentals of High-Shear Dispersers
To create "dispersions" of solids, gases or immiscible liquids, a disperser must break the added components into individual particles, gas bubbles or liquid …
Combining the D3 dispersion correction with the neuroevolution machine
Machine-learned potentials (MLPs) have become a popular approach of modeling interatomic interactions in atomistic simulations, but to keep the computational cost under control, a relatively short cutoff must be imposed, which put serious restrictions on the capability of the MLPs for modeling relatively long-ranged dispersion interactions.

Deep Learning for Extracting Dispersion Curves | Surveys in …
A large number of dispersion curves need to be extracted for inversion, especially for surveys with long two-dimensional sections or large three-dimensional (3D) coverages. Human–machine interaction-based dispersion curves extraction, however, is still common, which is time-consuming.
Dispersing
Dispersing is the mixing of at least two substances that do not dissolve or hardly dissolve in each other and do not chemically react with one another. The goal while producing an industrial dispersion is to create a "satisfactorily" fine distribution in the continuous phase. A suspension is created when solid particles are dispersed in a liquid.
