Structural equation modeling (SEM) encompasses such diverse statistical techniques as path analysis, confirmatory factor analysis, causal modeling with latent variables, and even analysis of variance ...

Researchers used a process called symbolic regression to derive the equations from a biogeochemical model of the ocean.

In the past few decades, the use of phase field-modeling equations for mathematical modeling has progressed. Phase separation has been studied extensively in thermodynamics and materials engineering, ...

Sometimes ecological data just don’t make sense. The sockeye salmon that spawn in British Columbia’s Fraser River offer a prime example. Scientists have tracked the fishery there since 1948, through ...

Clouds are made up of individual, microscopic spheres of water, or hydrometeors, that change and interact with one another based on environmental conditions and the characteristics of the hydrometeor ...

Computational models and simulations have had an important role in engineering analysis since as far back as the 1960s. It is widely recognized that the use of modeling and simulation tools can make ...

A closed-loop drilling system, to be effective, requires reliable two-way communication between the downhole module and surface. 1 2 Today's drilling industry uses mud-pressure pulse telemetry as one ...
