Linear non-normal energy amplification of harmonic and stochastic forcing in turbulent channel flow [PDF]
, 2010 The linear response to stochastic and optimal harmonic forcing of small coherent perturbations to the turbulent channel mean flow is computed for Reynolds numbers ranging from Re_tau=500 to Re_tau=20000.

Open global shadow graph and it’s zero forcing number
, 2023 Zero forcing number of a graph is the minimum cardinality of the zero forcing set. A zero forcing set is a set of black vertices of minimum cardinality that can colour the entire graph black using the color change rule: each vertex of G is coloured ...

The failed zero forcing number of a graph [PDF]
Involve, a Journal of Mathematics, 2015 Given a graph G, the zero forcing number of G, Z(G), is the smallest cardinality of any set S of vertices on which repeated applications of the color change rule results in all vertices joining S. The color change rule is: if a vertex v is in S, and exactly one neighbor u of v is not in S, then u joins S in the next iteration.

Metric dimension and zero forcing number of two families of line graphs [PDF]
, 2012 summary:Zero forcing number has recently become an interesting graph parameter studied in its own right since its introduction by the “AIM Minimum Rank–Special Graphs Work Group”, whereas metric dimension is a well-known graph parameter.

Line graphs: Their maximum nullities and zero forcing numbers [PDF]
Czechoslovak Mathematical Journal, 2016 The main aim of this paper is to analyze the maximum nullity and zero forcing number, and their positive counterparts, for general families of line graphs associated with graphs possessing some specific properties. In [\textit{F. Barioli} et al., Linear Algebra Appl. 428, No.

Computing the Zero Forcing Number for Generalized Petersen Graphs [PDF]
, 2020 Let G be a simple undirected graph with each vertex colored either white or black, u be a black vertex of G, and exactly one neighbor v of u be white. Then change the color of v to black. When this rule is applied, we say u forces v, and write u ® v .
