On the sum of narrow and C-compact operators
Владикавказский математический журнал, 2018 В работе рассматриваются узкие линейные операторы, заданные на пространстве Банаха - Канторовича и принимающие значение в банаховом пространстве. Установлено, что сумма двух операторов S+T, где S - узкий оператор, а T- (bo)-непрерывный C-компактный оператор, также является узким оператором.

Daugavet centers are separably determined [PDF]
Математичні Студії, 2013 A linear bounded operator $G$ acting from a~Banach space $X$ intoa~Banach space $Y$ is a~Daugavet center if every linear boundedrank-$1$ operator $Tcolon X o Y$ fulfills$|G+T|=|G|+|T|$.

Data assimilation for volcanic ash plumes using a satellite observational operator: a case study on the 2010 Eyjafjallajökull volcanic eruption [PDF]
Atmospheric 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
Safety, 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 $c_0(\Gamma)$
Karpatsʹkì 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 $E$.

SIGNIFICANT WAVE HEIGHT DETERMINED FROM SEQUENCE OF X-BAND RADAR IMAGES USING TEAGER-HUANG TRANSFORM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 This work introduces a nonlinear and data-dependant method for extracting the significant wave height from a sequence of X-band radar images, which is based on the Teager-Huang Transform (THH).
