Sentence examples for use of empirical models from inspiring English sources

This study is focused on the optimization of carriers for pulmonary drug delivery systems with the use of empirical models.

To overcome the constraints related to the use of empirical models in the flood project evaluation for isolated spillways design of earth dams, a variant of a submersible RCC dam has been studied with a spillway incorporated in dam's body.

For example, the radio propagation community makes considerable use of empirical models such as the global IRI, or the European COST-PRIME and COST-PROF family of models, which describe the average conditions of the unperturbed, sub-auroral ionosphere (Bilitza 1992; Bradley 1995; Hanbaba 1995; Zolesi and Cander 2004).

The elastic modulus of intact rock is used for many rock engineering projects, such as tunnels, slopes, and foundations, but due to the requirements of high-quality core samples and associated sophisticated test equipment, instead the use of empirical models to obtain this parameter has been an attractive research topic.

We illustrate potential pitfalls of structural equation modelling by criticizing their model for (a) its neglect of latent variables, (b) its complexity, (c) its questionable causal assumptions, (d) the use of empirical model reduction, (e) the mix-up of theoretical perspectives, and (f) the failure to compare alternative models.

We use a trio of empirical models to estimate the relative contributions of solar extreme ultraviolet heating, Joule heating and particle heating to the global energy budget of the earth's upper atmosphere.

The regression analysis has been used for the development of empirical models able to describe the effect of the process parameters on the quality of the cutting.

Finally, the pertinence of empirical models used by the Raman community is discussed.

The recent development of empirical models using pattern recognition techniques and neural networks (Nakamura et al. 2007, 2009; Wang et al. 2013; Zhao et al. 2014) allowed for a significant improvement of the forecast quality in comparison with the IRI model, as they are easy to implement automatically and flexible enough.

However, uncertainties exist among the codes because of the use of different empirical models.

Of course, the use of empirical channel models have disadvantages: they are difficult to generalize (although there exist hybrid models that mix empirical and theoretical contributions (e.g. [9])) and they are less accurate than other kinds of models (e.g. PHY models) in certain situations, since they usually require approximations.
