Higher spectral flow and an entire bivariant JLO cocycle

open access: yes, 2012
Given a smooth fibration of closed manifolds and a family of generalised Dirac operators along the fibers, we define an associated bivariant JLO cocycle. We then prove that, for any $\ell \geq 0$, our bivariant JLO cocycle is entire when we endow smoooth

The reservoir network: A new network topology for district heating and cooling [PDF]

open access: yes, 2020
Thermal district networks are effective solutions to substitute fossil fuels with renewable energy sources for heating and cooling. Moreover, thermal networking of buildings allows energy efficiency to be further increased.

Usage based topology for DCNs

open access: yes2015 IEEE International Conference on Communications (ICC), 2015
Many data center network topologies are designed to provide full bisection bandwidth for tens of thousands of servers in order to achieve high network throughput and server agility. However, the utilization rate of DCNs on average is below 10%, which results in a significant waste of network resources and energy.

Orderability and continuous selections for Wijsman and Vietoris hyperspaces

open access: yesApplied General Topology, 2003
Bertacchi and Costantini obtained some conditions equivalent to the existence of continuous selections for the Wijsman hyperspace of ultrametric Polish spaces. We introduce a new class of hypertopologies, the macro-topologies.

Topology of the set of univoque bases

open access: yesTopology and its Applications, 2016
Abstract Given a positive integer M, a number q > 1 is called a univoque base if there is exactly one sequence ( c i ) = c 1 c 2 ⋯ with integer digits c i belonging to the set { 0 , 1 , … , M } , such that 1 = ∑ i = 1 ∞ c i q − i .

Bases of topological epi-reflections

open access: yesTopology and its Applications, 1980
AbstractIn the first part of this paper a characterization of epi-reflective subcategories of the category TOP of topological spaces in terms of initial topologies is given. This characterization enables us to associate to each epi-reflective subcategory of TOP, regular systems of cogenerators.

Topology Adaption for the Quantum Internet

open access: yes, 2018
In the quantum repeater networks of the quantum Internet, the varying stability of entangled quantum links makes dynamic topology adaption an emerging issue. Here we define an efficient topology adaption method for quantum repeater networks.

The Upgrade of Topological Group Based on a New Hyper-topology [PDF]

open access: yesFuzzy Information and Engineering, 2011
Wang et al [1] have put forward the problem of upgrade of topology and obtained a series of systematic theories and applicable results. Li et al [2] have put forwarded the problem of upgrade of group and also obtained a series of results. Consequently, the problem of upgrade of mathematic structure has drawn more attention of researchers.

A New Topology-Switching Strategy for Fault Diagnosis of Multi-Agent Systems Based on Belief Rule Base

open access: yesEntropy, 2022
Effective fault-diagnosis strategies have been the focus of research on multi-agent systems (MASs). In this paper, the belief rule base (BRB)-based distributed fault-diagnosis problem for MASs is investigated, and a topology-switching strategy is ...

Topological dynamics on hyperspaces

open access: yesApplied General Topology, 2010
In this paper we wish to relate the dynamics of the base map to the dynamics of the induced map. In the process, we obtain conditions on the endowed hyperspace topology under which the chaotic behaviour of the map on the base space is inherited by the ...
