Members are represented as nodes, and each distinct interaction between any two members is represented by a directed arc.
For each pair of nodes connected by a directed arc, the node with the outgoing arc was called a parent of the node with the incoming arc.
Dependencies are represented qualitatively by a directed acyclic graph where each node corresponds to a variable, and a direct arc between nodes represents a direct influence.
Consequently, each term in (v_{k}bar{beta}_{kj}) is the weight (w(Q)) of a unicyclic subgraph Q of (mathcal{G}) obtained from such a tree T by adding a directed arc ((k,j)) from vertex k to vertex j.
We define the oriented graph G ⪯ in X as follows: the vertices of G ⪯ are the elements of X, and two vertices x, y ∈ X are connected by a directed edge (arc) if x ⪯ y.
A path of length l in G is a sequence v p 1,…, v p i, v p i +1,…, v p l of l nodes, where each pair v p i, v p i +1 of consecutive nodes is connected by a directed edge (arc), which starts in v p i and ends in v p i +1.
A few-layered graphene nanosheets on a Ta thin film were synthesized by a direct current (DC) arc plasma jet chemical vapor deposition (CVD) process that does not critically depend on cooling rates.
The transformer rating is derived from the operating conditions of a medium size direct arc furnace.
A two-way dependency relationship between attributes in two different clusters was called inter-dependency, denoted by a two-way directed arc between the clusters.
MgO nanobelts were obtained by magnesium nitrate decomposition using the direct arc plasma jet chemical vapor deposition technique, with a molybdenum substrate at 950 °C for 5 min.
