Variations of zero forcing and power domination

open access: yes, 2022
Zero forcing is a propagation process on a graph that turns white vertices into blue vertices. In this process, an initial set of vertices in a graph $G$ are chosen to be blue and all others are colored white, then a color-change rule is iteratively ...

Large-Eddy Simulation of Flow Separation and Control on a Wall-Mounted Hump [PDF]

open access: yes, 2009
Active flow control techniques such as synthetic jets have been successful in increasing the performance of naturally separating flows on post-stall airfoils, bluff body shedding, and internal flows such as wide-angle diffusers.

Entrainment and mixing at the interface of shallow cumulus clouds: Results from a combination of observations and simulations

open access: yesMeteorologische Zeitschrift, 2014
This study combines observations, large-eddy simulations (LES), and direct numerical simulations (DNS) in order to analyze entrainment and mixing in shallow cumulus clouds at all relevant spatial scales and, additionally, to verify the results by the ...

Extracting learning backbones: a zero-forcing-based approach to graph sparsification for graph classification

open access: yesApplied Network Science
This paper introduces a control-theoretic framework for graph sparsification aimed at constructing sparse subgraphs that retain the learning capacity of the original graph, reducing structural complexity while maintaining downstream performance. We refer

Deep Learning-Based Contrail Segmentation in Thermal Infrared Satellite Cloud Images via Frequency-Domain Enhancement

open access: yesRemote Sensing
Aviation contrails significantly impact climate via radiative forcing, but their segmentation in thermal infrared satellite images is challenged by thin-layer structures, blurry edges, and cirrus cloud interference. We propose MFcontrail, a deep learning

Five Driving Forces of Multi-Access Edge Computing

open access: yesCoRR, 2018
The emergence of Multi-Access Edge Computing (MEC) technology aims at extending cloud computing capabilities to the edge of the wireless access networks. MEC provides real-time, high-bandwidth, low-latency access to radio network resources, allowing operators to open their networks to a new ecosystem and value chain.

Chaotic Oscillation via Edge of Chaos Criteria

open access: yes, 2017
In this paper, we show that nonlinear dynamical systems which satisfy the edge of chaos criteria can bifurcate from a stable equilibrium point regime to a chaotic regime by periodic forcing.

A Fog Computing Enabled Virtual Power Plant Model for Delivery of Frequency Restoration Reserve Services

open access: yesSensors, 2019
Nowadays, centralized energy grid systems are transitioning towards more decentralized systems driven by the need for efficient local integration of new deployed small scale renewable energy sources.

Relations between global forcing number and maximum anti-forcing number of a graph

open access: yes, 2020
The global forcing number of a graph G is the minimal cardinality of an edge subset discriminating all perfect matchings of G, denoted by gf(G). For any perfect matching M of G, the minimal cardinality of an edge subset S in E(G)-M such that G-S has a ...

Large-Scale Structure of a Leading-Edge Separation Bubble with Local Forcing

open access: yes, 1995
POD (proper orthogonal decomposition) is applied to turbulent leading-edge separation bubble to extract coherent structures. A two-dimensional leading-edge separation bubble is simulated by discrete-vortex method, where a time-dependent source forcing is
