Journal of Natural Resources and Development, 2018 Soil erosion is one of the major environmental threats in the northwestern Amhara Region of Ethiopia. The objective of this study is to assess the spatial heterogeneity of soil erosion risk within the Gumara-Maksegnit watershed (57.3 km2) using the ...

Two versions of a specific natural extension [PDF]
arXiv, 2008 We give two versions of the natural extension of a specific greedy beta-transformation with deleted digits. We use the natural extension to obtain an explicit expression for the invariant measure, equivalent to the Lebesgue measure, of this beta-transformation.

Disentangling images with Lie group transformations and sparse coding [PDF]
arXiv, 2020 Discrete spatial patterns and their continuous transformations are two important regularities contained in natural signals. Lie groups and representation theory are mathematical tools that have been used in previous works to model continuous image transformations.

On Some q-Analogues of the Natural Transform and Further Investigations [PDF]
arXiv, 2015 Some q-analogues of classical integral transforms have recently been investigated by many authors in diverse citations. The q-analogues of the Natural transform are not known nor used. In the present paper, we are concerned with definitions and investigations of the q-theory of the Natural transform and some applications.

Exact solutions of the Laplace fractional boundary value problems via natural decomposition method
Open Physics, 2020 In this article, exact solutions of some Laplace-type fractional boundary value problems (FBVPs) are investigated via natural decomposition method. The fractional derivatives are described within Caputo operator.

A natural extension for the greedy beta-transformation with three deleted digits [PDF]
arXiv, 2008 We give an explicit expression for the invariant measure, absolutely continuous with respect to the Lebesgue measure, of the greedy beta-transformation with three deleted digits. We define a version of the natural extension of the transformation to obtain this expression. We get that the transformation is exact and weakly Bernoulli.

A remark on Yoneda's Lemma [PDF]
arXiv, 2017 Yoneda'e Lemma is about the canonical isomorphism of all the natural transformations from a given representable covariant (contravariant, reps.) functor (from a locally small category to the category of sets) to a covariant (contravariant, reps.) functor.
