Internal boundary layer in a singularly perturbed problem of fractional derivative

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
This paper is devoted to the study of internal boundary layer. Such motions are often associated with effect of boundary layer, i.e. low flow viscosity affects only in a narrow parietal layer of a streamlined body, and outside this zone the flow is as ...

Data assimilation for volcanic ash plumes using a satellite observational operator: a case study on the 2010 Eyjafjallajökull volcanic eruption [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Using data assimilation (DA) to improve model forecast accuracy is a powerful approach that requires available observations. Infrared satellite measurements of volcanic ash mass loadings are often used as input observations for the assimilation scheme ...

Air Force Pilot Expertise Assessment during Unusual Attitude Recovery Flight

open access: yesSafety, 2022
Pilot training and expertise are key aspects in aviation. A traditional way of evaluating pilot expertise is to measure performance output. However, this approach provides a narrow view of the pilot’s capacity, especially with regard to mental and ...

A note on operators from Kothe function spaces to $c_0(\Gamma)$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
It is well known that every operator from $E = L_p$, $1 \leq p <\infty$ to $c_0$ is narrow. We show that this result can be extended to a more general class of Kothe function spaces $E$.
