Preparation and measurement: two independent sources of uncertainty in quantum mechanics [PDF]

open access: yes, 1999
In the Copenhagen interpretation the Heisenberg uncertainty relation is interpreted as the mathematical expression of the concept of complementarity, quantifying the mutual disturbance necessarily taking place in a simultaneous or joint measurement of ...

Influence of attractive van der Waals interactions on the optimal excitations in thermocapillary-driven spreading [PDF]

open access: yes, 2003
Recent investigations of microfluidic flows have focused on manipulating the motion of very thin liquid films by modulating the surface tension through an applied streamwise temperature gradient.

Dynamic Stall Control by Passive Disturbance Generators [PDF]

open access: yesAIAA Journal, 2011
Passive cylindrical disturbance generators mounted near the leading edge of an airfoil significantly improved its performance under dynamic stall conditions. Time-resolved particle image velocimetry and simultaneous pressure measurements were conducted at the midchord of a pitching airfoil equipped with passive disturbance generators.

Generalized Super-Twisting Backstepping Sliding Mode Control for Electro-Hydraulic Servo Systems Considering the Coexistence of Matched and Mismatched Uncertainties

open access: yesApplied Sciences, 2023
Aiming at the problem of the coexistence of matching and mismatching uncertainties in electro-hydraulic servo systems, disturbance observers and a backstepping sliding mode controller based on the generalized super-twisting algorithm (GSTA) are proposed ...

Residual error-disturbance uncertainties in successive spin-1/2 measurements tested in matter-wave optics

open access: yes, 2015
The indeterminacy inherent in quantum measurement is an outstanding character of quantum theory, which manifests itself typically in Heisenberg's error-disturbance uncertainty relation.

Thinning and disturbance growth in liquid films mobilized by continuous surfactant delivery [PDF]

open access: yes, 2003
A generalized linear stability analysis is applied to the case of a thin liquid film propelled to spread by a continuous supply of surfactant. The time-dependent base states for the film thickness and surfactant concentration give rise to a nonautonomous

Disturbance in weak measurements and the difference between quantum and classical weak values

open access: yes, 2015
The role of measurement induced disturbance in weak measurements is of central importance for the interpretation of the weak value. Uncontrolled disturbance can interfere with the postselection process and make the weak value dependent on the details of ...

Water waves generated by disturbances at an ice cover [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
This paper is concerned with twoโ€dimensional unsteady motion of water waves generated by an initial disturbance created at an ice sheet covering the water. The ice cover is modeled as a thin elastic plate. Using linear theory, the problem is formulated as an initial value problem for the velocity potential describing the motion in the liquid.

Generalized ๐‘†(๐ถ,๐ด,๐ต)-Pairs for Uncertain Linear Infinite-Dimensional Systems

open access: yesJournal of Applied Mathematics, 2009
We introduce the concept of generalized ๐‘†(๐ถ,๐ด,๐ต)-pairs which is related to generalized ๐‘†(๐ด,๐ต)-invariant subspaces and generalized ๐‘†(๐ถ,๐ด)-invariant subspaces for infinite-dimensional systems.
