Adaptive time varying autopilot design [PDF]
Scientific Technical Review, 2016 Missile autopilots represent devices for precise following of a target that missiles are sent to intercept. Commands that need to be executed are forwarded to the autopilot in order to achieve demanded performance.

Estimation of time-space-varying parameters in dengue epidemic models
Communication in Biomathematical Sciences, 2017 There are nowadays a huge load of publications about dengue epidemic models, which mostly employ deterministic differential equations. The analytical properties of deterministic models are always of particular interest by many experts, but their validity

Numerical Study on Identification of Time Varying Parameters of Vibration Systems
Shock and Vibration, 1997 An on-line least squares algorithm has previously been successfully applied to linear vibration systems in order to identify time varying parameters. In this article the limitations of the approach and the factors affecting the identification are further
