Internal Decoupling in Nonlinear Process Control

Jens G. Balchen, Bernt Lie, Ingar Solberg • Modeling, Identification and Control (1988)

A simple method has been investigated for the total or partial removal of the effect of non-linear process phenomena in multi-variable feedback control systems. The method is based upon computing the control variables which will drive the p...

Generic Riemannian Maps from Nearly Kaehler Manifolds

Richa Agarwal, Shahid Ali • Computer Sciences & Mathematics Forum (2023)

In order to generalise semi-invariant Riemannian maps, Sahin first introduced the idea of “Generic Riemannian maps”. We extend the idea of generic Riemannian maps to the case in which the total manifold is a nearly Kaehler manifold. We stud...

Mathematics and Indispensability

Elliott R. Sober • The Philosophical Review (1993)

Mathematics plays an indispensable role in the explanations that modern science provides of empirical phenomena. From this unexceptionable observation, a controversial philosophical conclusion is sometimes drawn. The claim is advanced that ...
