Ergodicity Space for Measure-Preserving Transformations [PDF]
Chinese Journal of Mathematics, 2016 We introduce the concept of ergodicity space of a measure-preserving transformation and will present some of its properties as an algebraic weight for measuring the size of the ergodicity of a measure-preserving transformation. We will also prove the invariance of the ergodicity space under conjugacy of dynamical systems.

Integration of acoustic radiation force and optical imaging for blood plasma clot stiffness measurement. [PDF]
PLoS ONE, 2015 Despite the life-preserving function blood clotting serves in the body, inadequate or excessive blood clot stiffness has been associated with life-threatening diseases such as stroke, hemorrhage, and heart attack.

Fourier Transforms and Measure-Preserving Transformations [PDF]
Proceedings of the American Mathematical Society, 1974 There exists a continuous function f f on the real line, vanishing at infinity, such that, for every measure-preserving transformation h h , the composition f ∘ h f \circ h fails to be a Fourier transform.

The spectral measure and Hilbert transform of a measure-preserving transformation [PDF]
Transactions of the American Mathematical Society, 1989 V. F. Gaposhkin gave a condition on the spectral measure of a normal contraction on L 2 {L^2} sufficient to imply that the operator satisfies the pointwise ergodic theorem. We prove that unitary operators which come from measure-preserving transformations satisfy a stronger version of this condition.

Logical entropy of dynamical systems
Advances in Difference Equations, 2018 The main purpose of the paper is to extend the results of Ellerman (Int. J. Semant. Comput. 7:121–145, 2013) to the case of dynamical systems. We define the logical entropy and conditional logical entropy of finite measurable partitions and derive the ...

Image completion via transformation and structural constraints
EURASIP Journal on Image and Video Processing, 2020 Image completion is an approach to fill a damaged region (hole) in an image. In this study, we adopt a novel method which can repair a target region with structural constraints in an architectural scene. An objective function that consists of three terms

International Journal for Research in Vocational Education and Training, 2021 Context: Dual VET systems are often praised for their labour market proximity because of economic stakeholders’ involvement. However, when labour market requirements change rapidly, a lack of flexibility is attributed to them.

Almost everywhere convergence of convolution powers without finite second moment [PDF]
, 2010 We generalize a theorem of Bellow and Calder\'on concerning the a.e. convergence of the convolution powers $\ds \mu^nf(x)=\sum_{k}\mu^n(k)f(T^k x)$ where $T$ is a measure preserving transformation of a probability space and $\mu$ is a probability measure
