Analysis of the unstable Tollmien-Schlichting mode on bodies with a rounded leading edge using the parabolized stability equation [PDF]

, 2008
The interaction between free-stream disturbances and the boundary layer on a body with a rounded leading edge is considered in this paper. A method which incorporates calculations using the parabolized stability equation (PSE) in the Orr-Sommerfeld ...

A Novel Model-Free Continuous Sliding Mode Controller with a PI Sliding Surface for Industrial Robots: Achieving Near-Zero Tracking Errors and GUUB Stability [PDF]

The Egyptian International Journal of Engineering Sciences and Technology
This study presents a novel continuous sliding mode control (SMC) law for robotic arms, emphasizing computational efficiency, structural simplicity, and stability. The proposed controller, which does not require the robot's dynamic model in its structure,

Stability of Growth Models with Generalised Lag Structures [PDF]

This paper considers the lag structures of dynamic models in economics, arguing that the standard approach is too simple to capture the complexity of actual lag structures arising, for example, from production and investment decisions.

Global Stability of a Premixed Reaction Zone (Time-Dependent Liñan’s Problem) [PDF]

, 1990
Global stability properties of a premixed, three-dimensional reaction zone are considered. In the nonadiabatic case (i.e., when there is a heat exchange between the reaction zone and the burned gases) there is a unique, spatially one-dimensional steady ...

Nash Equilibrium and Robust Stability in Dynamic Games: A Small-Gain Perspective [PDF]

This paper develops a novel methodology to study robust stability properties of Nash equilibrium points in dynamic games. Small-gain techniques in modern mathematical control theory are used for the first time to derive conditions guaranteeing uniqueness

Invariant Regions and Global Asymptotic Stability in an Isothermal Catalyst [PDF]

, 1988
A well-known model for the evolution of the (space-dependent) concentration and (lumped) temperature in a porous catalyst is considered. A sequence of invariant regions of the phase space is given, which converges to a globally asymptotically stable ...

Parameter estimation in nonlinear AR–GARCH models [PDF]

This paper develops an asymptotic estimation theory for nonlinear autoregressive models with conditionally heteroskedastic errors. We consider a general nonlinear autoregression of order p (AR(p)) with the conditional variance specified as a general ...
