A Comparative Evaluation of Artificial Neural Network and Sunshine Based models in prediction of Daily Global Solar Radiation of Lalibela, Ethiopia

Cogent Engineering, 2022
Due to a lack of solar radiation measurement instruments in various regions across the world, particularly in Ethiopia, many empirical models have been developed to estimate global solar radiation. Reliable global solar radiation information is essential

A Global Empirical Model for Near‐Real‐Time Assessment of Seismically Induced Landslides

Journal of Geophysical Research: Earth Surface, 2018
Earthquake‐triggered landslides are a significant hazard in seismically active regions, but our ability to assess the hazard they pose in near‐real‐time is limited.

Empirical Models

, 2016
In experimental or clinical pharmacokinetics, the simplest experiment consists in administering, in a rapid input, a large number of drug molecules having the same pharmacological properties and then in the subsequent time interval, sampling biological fluids in order to follow the decline in number of molecules or in drug concentration.
