Green virtual topology design algorithm based on constraint-based routing
Tongxin xuebao, 2014 To reduce the energy consumption of Internet core network, a formulation model for green virtual topology design (GVTD) problem was developed, which employs the following measures: traffic aggregation, network resources allocation on demand, virtual ...

Topological and semi-topological Galois embedding problems [PDF]
arXivWe reformulate the embedding problem in Galois theory as a question within the frameworks of topological and semi-topological Galois theory. We prove that these problems are solvable when the fundamental group of the base space is a free group of countable rank.

On ring-valued invariants of topological pairs [PDF]
arXiv, 2007 Based on the notion of a $\Delta$-group(oid), ring-valued invariants of pairs of topological spaces can be defined in intrinsic topological terms.

$Z_{2}$ Topological Order and Topological Protection of Majorana Fermion Qubits [PDF]
arXiv, 2017 The Kitaev chain model exhibits topological order that manifests as topological degeneracy, Majorana edge modes and $Z_{2}$ topological invariance of the abulk spectrum. This model can be obtained from a transverse field Ising model(TFIM) using the Jordan-Wigner transformation. TFIM has neither topological degeneracy nor any edge modes.

IEEE Access, 2018 This paper proposes a new design of a dual-polarized base station antenna for sub-6-GHz 5G communication covering the band from 3.3 to 3.8 GHz. The proposed antenna offers a good impedance matching across the desired frequency band with $\text {VSWR ...

Development of Active External Network Topology Module for Floodlight SDN Controller
Моделирование и анализ информационных систем, 2015 Traditional network architecture is inflexible and complicated. This observation has led to a paradigm shift towards software-defined networking (SDN), where network management level is separated from data forwarding level.

Projected p-wave superconducting wave-functions for topological orders [PDF]
arXiv, 2007 In this paper we develop a sysmatical theory for topological orders by the projected p-wave superconducting (SC) wave-functions and unify the different topological orders for spin models into the fermionic picture. We found that the energy for the fermions at k=(0,0), (0, pi), (pi, 0), (pi, pi) acts as a topological invariable to characterize 16 ...
