A semi-empirical model of the aerodynamics of manoeuvring insect flight. [PDF]
Blade element modelling provides a quick analytical method for estimating the aerodynamic forces produced during insect flight, but such models have yet to be tested rigorously using kinematic data recorded from free-flying insects.

Numerical modeling of ASR: an updated semi-empirical model
Alkali-silica reaction (ASR) is a deleterious expansion phenomenon affecting concrete structures worldwide. It occurs when a susceptible chemical composition of concrete components is present, and it is particularly rampant in inherently humid ...

Soybean root elongation in relation to water and mechanical stresses in intact and disturbed structures of an Oxisol [PDF]
IntroductionProcess-based root growth simulation models detail soil-root interactions, but do not incorporate the role of soil structure dynamics. Our objective was to parameterize the soybean root elongation under mechanical and hydric stress levels for

Constructing Semi-Empirical Sunspot Models for Helioseismology [PDF]
One goal of helioseismology is to determine the subsurface structure of sunspots. In order to do so, it is important to understand first the near-surface effects of sunspots on solar waves, which are dominant. Here we construct simplified, cylindrically-symmetric sunspot models, which are designed to capture the magnetic and thermodynamics effects ...

Development of semi-empirical model for radiochemical reactions [PDF]
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.
