The Watt centrifugal governor is a device that automatically controls the speed of an engine. Dating to 1788, it can be taken as the starting point for automatic control theory (see MacFarlane [5] and references therein). In this paper the system coupling the Watt-centrifugal-governor and the steamengine will be called simply the Watt Governor System (WGS). Landmarks for the study of the local ...

Hypersonic boundary-layer stability has significant importance in vehicle design and successful operation. This paper investigates the stabilization effects of local wall cooling on hypersonic boundary layers over a 5 deg half-angle blunt cone with nose radius 0.0254 mm. We employed high-order-accurate flow solver to calculate steady for freestream Mach number 6.0 unit Reynolds [Formula: see te...

This paper introduces and analyzes an evolutionary model of a financial marketwith a risk-free asset. Focus is on the study of local stability of the wealth dynamics through the application of recent results on the linearization and stability of random dynamical systems (Evstigneev et al. Proc Am Math Soc 139:1061–1072, 2011). Conditions are derived for the linearization of the model at an equi...
