The Role of Visual Scaffolding in Enhancing Iranian EFL Students’ Writing Ability [PDF]

open access: yesIssues in Language Teaching, 2019
To better illuminate the link between scaffolding and visual aids, this quasi-experimental study attempted to scaffold an intact group of 14 intermediate-level Iranian English as a foreign language (EFL) learners through providing graphs with the aim of ...

Drawing Graphs Within Graphs

open access: yesJournal of Graph Algorithms and Applications, 2005
Summary: The task of drawing subgraphs is often underestimated and they are simply emphasized using different colors or line styles. In this paper, we present an approach for drawing graphs within graphs that first produces a layout for the subgraphs thus increasing their locality.

Classifying image analysis techniques from their output

open access: yesInternational Journal of Computational Intelligence Systems, 2016
In this paper we discuss some main image processing techniques in order to propose a classification based upon the output these methods provide. Because despite a particular image analysis technique can be supervised or unsupervised, and can allow or not

Biclique Graphs of K3-free Graphs and Bipartite Graphs

open access: yesProcedia Computer Science, 2021
A biclique of a graph is a maximal complete bipartite subgraph. The biclique graph of a graph $G$, $KB(G)$, defined as the intersection graph of the bicliques of $G$, was introduced and characterized in 2010. However, this characterization does not lead to polynomial time recognition algorithms.

Interaction graphs: Graphings

open access: yesAnnals of Pure and Applied Logic, 2017
In two previous papers, we exposed a combinatorial approach to the program of Geometry of Interaction, a program initiated by Jean-Yves Girard. The strength of our approach lies in the fact that we interpret proofs by simpler structures - graphs - than Girard's constructions, while generalizing the latter since they can be recovered as special cases of

Graphs whose line graphs are ring graphs [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Given a graph H, a path of length at least two is called an H-path if meets H exactly in its ends. A graph G is a ring graph if each block of G which is not a bridge or a vertex can be constructed inductively by starting from a single cycle and then in each step adding an H-path that meets graph H in the previous step in two adjacent vertices.

Packing Smaller Graphs into a Graph

open access: yesDiscrete Mathematics, 1989
Let G be a connected graph and \(\alpha_ m(G)\) denote the largest number of vertex-disjoint connected subgraphs \(H_ 1,H_ 2,...,H_ k\) of G each having m vertices. The authors obtain the following bounds for the m-packing number \(\alpha_ m(G)\) for a connected graph G of order n and maximum degree \(\Delta\). \[ \lceil \frac{n-m+1}{(m-1)(\Delta -1)+1}

A Novel Similarity Score for Link Prediction Approach Using Financial Transaction Networks and Firms’ Attribute

open access: yesIEEE Access
Financial transaction networks represent inter-firm relationships, where firms and transactions act as nodes and edges, respectively. Link prediction in these networks aims to identify potential future or missing transactions or links, providing valuable

Graph Passing in Graph Transformation.

open access: yesElectron. Commun. Eur. Assoc. Softw. Sci. Technol., 2012
Graph transformation works under the whole world assumption. Therefore, in realistic systems, both the individual graphs and the set of all such graphs can grow very large. In reactive formalisms such as process algebra, on the other hand, each system is split into smaller components which continually interact; the interactions pass information such as
