On Differential Operators and Connections [PDF]

open access: yesTransactions of the American Mathematical Society, 1961
In this paper we construct, for an arbitrary principal bundle (with group a real Lie group) over a differentiable manifold, a sheaf of germs of linear differential operators of first order operating on the sheaf of germs of sections of any differentiable vector bundle associated with the given principal bundle. The commutators of these operators define

Certain Properties and Characterizations of Two-Iterated Two-Dimensional Appell and Related Polynomials via Fractional Operators

open access: yesFractal and Fractional
This paper introduces the operational rule for 2-iterated 2D Appell polynomials and derives its generalized form using fractional operators. It also presents the generating relation and explicit forms that characterize the generalized 2-iterated 2D ...

Analysis of the transition between multiple operational modes for hybrid AC/DC microgrids

open access: yesCSEE Journal of Power and Energy Systems, 2018
There are four basic operational modes for the hybrid AC/DC microgrid, including AC grid-connected while interconnecting, both off-grid while interconnecting, AC gridconnected without connection, and both off-grid without connection.

Measurement incompatibility and steering are necessary and sufficient for operational contextuality

open access: yesPhysical Review Research, 2020
Contextuality is a signature of operational nonclassicality in the outcome statistics of an experiment. This notion of nonclassicality applies to a breadth of physical phenomena. Here, we establish its relation to two fundamental nonclassical entities in

Analysis on the Thermal Balance and Operational Parameters for the District Heating System with Peak Load Boilers in Heating Substations

open access: yesEnergies, 2020
This study proposes to use gas-fired boilers as peak shaving heat sources in heating substations due to their capability to increase the reliability, flexibility and heat capacity without the need to change the district heating network (DHN).

Practical Extensions of Connected Operators

open access: yes, 1996
This paper deals with the notion of connected operators. These operators are becoming popular in image processing because they have the fundamental property of simplifying the signal while preserving the contour information. In this paper, we discuss some practical approaches for the extension and the generalization of these operators. We focus on
