Modeling effects of disturbance across life history strategies of stream fishes
, 2021 A central goal of population ecology is to establish linkages between life history strategy, disturbance, and population dynamics. Globally, disturbance events such as drought and invasive species have dramatically impacted stream fish populations and ...

A nonlinear disturbance observer for robotic manipulators [PDF]
, 2000 A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...

Disturbance and temporal variability in invertebrate assemblages in two South African rivers [PDF]
, 2009 Includes abstract.This thesis presents an examination of the relationship between floods as disturbances, the disturbance regime and the temporal dynamics of invertebrate assemblages, over the short term and at intra- and inter-annual time scales in the ...

Disturbance-observer-based robust control for time delay uncertain systems [PDF]
, 2010 A robust control scheme is proposed for a class of systems with uncertainty and time delay based on disturbance observer technique. A disturbance observer is developed to estimate the disturbance generated by an exogenous system, and the design ...
