Output contraction analysis of nonlinear systems

CoRR, 2023
This paper introduce the notion of output contraction that expands the contraction notion to the time-varying nonlinear systems with output. It pertains to the systems' property that any pair of outputs from the system converge to each other exponentially.

Generalizations of Darbo’s fixed point-theorem and its application to the solvability of a nonlinear fractional differential equation [PDF]

Nonlinear Analysis
This paper introduces novel fixed-point theorems for generalized Proinov contraction mappings utilizing the measure of noncompactness. These results significantly extend existing contraction principles and provide novel methods for analyzing nonlinear ...

Three-dimensional flow of Newtonian and Boger fluids in square-square contractions [PDF]

, 2009
The flow of a Newtonian fluid and a Boger fluid through sudden square–square contractions was investigated experimentally aiming to characterize the flow and provide quantitative data for benchmarking in a complex three-dimensional flow.

An electrooptical muscle contraction sensor [PDF]

, 2010
An electrooptical sensor for the detection of muscle contraction is described. Infrared light is injected into the muscle, the backscattering is observed, and the contraction is detected by measuring the change, that occurs during muscle contraction ...

Effect of the contraction ratio upon viscoelastic fluid flow in three-dimensional square-square contractions [PDF]

, 2011
In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.

Note on Nonlinear Contraction Semigroups [PDF]

Proceedings of the American Mathematical Society, 1969
1. Let X be a Banach space and let { F(£); 0^£< » } be a family of nonlinear operators from X into itself satisfying the following conditions: (i) T(0)=I (the identity) and T{£+7]) = T{£)T{v) for ?, t?^0. (ii) ||r(£)x-7X£);y||=g||x-3,|| for x, y EX. (iii) limj_o+ ||F(£)x — x|| =0 for xEX.
