Engineering is all about choosing the best compromise—both for a SPICE model that provides reasonable fidelity and for the tools enabling that model to be employed. A variety of linear models are ...

The transport and transformation of nitrogen (N) and dissolved organic carbon (DOC) originating from point sources such as effluent discharge or pond seepage are described by using a mechanistic ...

In its original form, Gibbs-Boltzmann statistical mechanics cannot describe “active matter,” such as living, driven, or self-propelled systems. Contemporary models of swarming and flocking behaviors, ...

There is considerable inherent error in equations for predicting width in gravel-bed rivers, and the relationship between width and bed load transport is poorly ...
