On robust stability of switched homogeneous systems
IET Control Theory & Applications, 2021 This paper analyses the robust stability of a class of homogeneous systems where a relation among the high‐order term, the decay rate and the domain of attraction of the system is explicitly established.

Gravity compensation and optimal control of actuated multibody system dynamics
IET Control Theory & Applications, 2022 This work investigates the gravity compensation topic, from a control perspective. The gravity could be levelled by a compensating mechanical system or in the control law, such as proportional derivative (PD) plus gravity, sliding mode control, or ...

Managing Spatial and Temporal Variability in Irrigated Agriculture Through Adaptive Control [PDF]
Australian Journal of Multi-Disciplinary Engineering, 2009 Spatial variability in crop production occurs as a result of spatial and temporal variations in soil structure and fertility; soil physical, chemical and hydraulic properties; irrigation applications; pests and diseases; plant genetics; and local microclimate.

The Singularity in Generic Gravitational Collapse Is Spacelike, Local, and Oscillatory [PDF]
, 1998 A longstanding conjecture by Belinskii, Khalatnikov, and Lifshitz that the singularity in generic gravitational collapse is spacelike, local, and oscillatory is explored analytically and numerically in spatially inhomogeneous cosmological spacetimes ...

Regional averaging and scaling in relativistic cosmology [PDF]
, 2002 Averaged inhomogeneous cosmologies lie at the forefront of interest, since cosmological parameters like the rate of expansion or the mass density are to be considered as volume-averaged quantities and only these can be compared with observations.

Factors Controlling the Spatial Variability of Mercury Distribution in Spanish Topsoil
Soil and Sediment Contamination: An International Journal, 2008 This study characterized the sources and scales of mercury variability in agricultural soils of the river Ebro (9.5 million ha) using geostatistical methods and data from 624 samples. The Ebro basin (20% of Spanish land mass) is an important agricultural area that is industrialized.
