Design Conformity of Indonesian-Made Mini Rice Combine Harvester and Anthropometry of Javanese Farmers

open access: yesAgritech, 2020
The combine harvester in Yogyakarta Province Special Region has a small size because it is used to harvest rice in a narrow area. The purpose of this study is to determine which parts of the mini combine harvester machine are not ergonomic and need to be

A study of local and non-local spatial densities in quantum field theory [PDF]

open access: yes, 2012
We use a one-dimensional model system to compare the predictions of two different 'yardsticks' to compute the position of a particle from its quantum field theoretical state.

On the sum of narrow and C-compact operators

open access: bronzeВладикавказский 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.

Generalized uncertainty relations: Theory, examples, and Lorentz invariance [PDF]

open access: yes, 1995
The quantum-mechanical framework in which observables are associated with Hermitian operators is too narrow to discuss measurements of such important physical quantities as elapsed time or harmonic-oscillator phase.

On a problem with nonperiodic frequent alternation of boundary condition imposed on fast oscillating sets [PDF]

open access: yes, 2005
We consider singular perturbed eigenvalue problem for Laplace operator in a cylinder with frequent and nonperiodic alternation of boundary conditions imposed on narrow strips lying in the lateral surface.

Modelling of VTS supervisor by algorithm based on Petri net: case study of Dover incident

open access: yesTransport, 2021
The paper deals with collision prevention problem in maritime transport in the area of the narrow canals with predefined routes. The Dover incident, which is analysed and described in the paper, has shown that the control of the passage of ships through ...

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 ...

Boolean independent sequences and Bourgain-Rosenthal’s theorem (in Ukrainian) [PDF]

open access: yesМатематичні Студії, 2012
A property of boolean independent sequences of pairs of sets is obtained. This completes the proof of Bourgain-Rosenthal's theorem on narrow operators.
