A Review on the Modeling of the Clinching Process Chain - Part I: Design Phase

Journal of Advanced Joining Processes, 2022
In many areas of product manufacturing, constructions are often mechanically joined of different materials to realize assemblies of various complexity with numerous point-shaped connections. Thereby, clinching is a frequently used joining technology. For

Connected Morphological Operators for Binary Images [PDF]

Computer Vision and Image Understanding, 1999
Summary: This paper presents a comprehensive discussion on connected morphological operators for binary images. Introducing a connectivity on the underlying space, every image induces a partition of the space in foreground and background components. A connected operator is an operator that coarsens this partition for every input image.

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

CSEE 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.

Certain Properties and Characterizations of Generalized Gould–Hopper-Based Hybrid Polynomials

Mathematics
This study offers a comprehensive generalization of the Gould–Hopper polynomials and their Appell-type analogs. Employing the quasi-monomiality approach, we delineate fundamental analytical characteristics, including recurrence relations, associated ...

Operational research in low-income countries: what, why, and how? [PDF]

, 2009
Operational research is increasingly being discussed at institutional meetings, donor forums, and scientific conferences, but limited published information exists on its role from a disease-control and programme perspective.

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

Fractal 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 ...

Measurement incompatibility and steering are necessary and sufficient for operational contextuality

Physical 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
