On the topology of generalized quotients [PDF]

open access: yesApplied General Topology, 2008
Generalized quotients are defined as equivalence classes of pairs (x, f), where x is an element of a nonempty set X and f is an element of a commutative semigroup G acting on X.

Methods for designing the next generation of aircraft architectures using topology optimisation [PDF]

open access: yes, 2010
The need from energy efficient transportation has resulted in a growing interest in new aircraft configurations such as the Blended Wing Body. There is very little collective knowledge on the optimal structural layouts of these aircraft, and the ...

Generalized Metric Spaces Do Not Have the Compatible Topology [PDF]

open access: yesAbstract and Applied Analysis, 2014
We study generalized metric spaces, which were introduced by Branciari (2000). In particular, generalized metric spaces do not necessarily have the compatible topology.

Generalized Abstracted Mean Values [PDF]

open access: yes, 1998
In this article, the author introduces the generalized abstracted mean values which extend the concepts of most means with two variables, and researches their basic properties and ...

Smooth boundary topology optimization applied to an electrostatic actuator [PDF]

open access: yes, 2008
Smooth boundary topology optimization (SBTO) avoids many of the problems encountered by conventional cell based systems coupled with material homogenization or density method. Shape optimization becomes part of topology optimization. The effectiveness of

open access: yes, 2009
This letter introduces a robust generalized state estimator which is able to detect and reject gross measurement errors, parameter errors, and topology errors simultaneously.

More on μ-semi-Lindelöf sets in μ-spaces

open access: yesDemonstratio Mathematica, 2021
Sarsak [On μ\mu -compact sets in μ\mu -spaces, Questions Answers Gen. Topology 31 (2013), no. 1, 49–57] introduced and studied the class of μ\mu -Lindelöf sets in μ\mu -spaces. Mustafa [μ\mu -semi compactness and

Partial metrizability in value quantales

open access: yesApplied General Topology, 2004
Partial metrics are metrics except that the distance from a point to itself need not be 0. These are useful in modelling partially defined information, which often appears in computer science.

Topological generalizations of network motifs [PDF]

open access: yesPhysical Review E, 2004
Biological and technological networks contain patterns, termed network motifs, which occur far more often than in randomized networks. Network motifs were suggested to be elementary building blocks that carry out key functions in the network. It is of interest to understand how network motifs combine to form larger structures.

On the Generalization of Tempered-Hilfer Fractional Calculus in the Space of Pettis-Integrable Functions

open access: yesMathematics, 2023
We propose here a general framework covering a wide range of fractional operators for vector-valued functions. We indicate to what extent the case in which assumptions are expressed in terms of weak topology is symmetric to the case of norm topology ...
