A novel algorithm to determine the leaf (leaves) of a binary tree from its preorder and postorder traversals
Volume 49, Issue 2 , December 2017, Pages 1-11
Abstract
Binary trees are essential structures in Computer Science. The leaf (leaves) of a binary tree is one of the most significant aspects of it. In this study, we prove that the order of a leaf (leaves) of a binary tree is the same in the main tree traversals; preorder, inorder, and postorder. Then, we prove ...

Volume 49, Issue 2 , December 2017, Pages 13-22
Abstract
Let $G$ be a graph with $p$ vertices and $q$ edges. The graph $G$ is said to be a super pair sum labeling if there exists a bijection $f$ from $V(G)\cup E(G)$ to $\{0, \pm 1, \pm2, \dots, \pm (\frac{p+q-1}{2})\}$ when $p+q$ is odd and from $V(G)\cup E(G)$ to $\{\pm 1, \pm 2, \dots, \pm (\frac{p+q}{2})\}$ ...

Volume 49, Issue 2 , December 2017, Pages 23-32
Abstract
A fuzzy graph is a symmetric binary fuzzy relation on a fuzzy subset. The concept of fuzzy sets and fuzzy relations was introduced by L.A.Zadeh in 1965\cite{zl} and further studied\cite{ka}. It was Rosenfeld\cite{ra} who considered fuzzy relations on fuzzy sets and developed the theory of fuzzy graphs ... Read MoreVulnerability Measure of a Network - a Survey
Volume 49, Issue 2 , December 2017, Pages 33-40
Abstract
In this paper we discuss about tenacity and its properties in stability calculation. We indicate relationships between tenacity and connectivity, tenacity and binding number, tenacity and toughness. We also give good lower and upper bounds for tenacity. Since we are primarily interested in the case where ... Read Morek-Remainder Cordial Graphs
Volume 49, Issue 2 , December 2017, Pages 41-52
Abstract
In this paper we generalize the remainder cordial labeling, called $k$-remainder cordial labeling and investigate the $4$-remainder cordial labeling behavior of certain graphs. Read MoreA new indexed approach to render the attractors of Kleinian groups
Volume 49, Issue 2 , December 2017, Pages 53-62
Abstract
One widespread procedure to render the attractor of Kleinian groups, appearing in the renown book [8], wantshuge memory resources to compute and store the results. We present a new faster and lighter version that drops the original array and pulls out group elements from integers.

Volume 49, Issue 2 , December 2017, Pages 63-101
Abstract
Sugeno-Weber family of t-norms and t-conorms is one of the most applied one in various fuzzy modelling problems. This family of t-norms and t-conorms was suggested by Weber for modeling intersection and union of fuzzy sets. Also, the t-conorms were suggested as addition rules by Sugeno for so-called ... Read MoreNew Algorithm For Computing Secondary Invariants of Invariant Rings of Monomial Groups
Volume 49, Issue 2 , December 2017, Pages 103-111
Abstract
In this paper, a new algorithm for computing secondary invariants of invariant rings of monomial groups is presented. The main idea is to compute simultaneously a truncated SAGBI-\G basis and the standard invariants of the ideal generated by the set of primary invariants. The advantage ...

Volume 49, Issue 2 , December 2017, Pages 113-118
Abstract
Some near-regular mechanical systems involve global deviations from their corresponding regular system. Despite extensive research on vibration analysis (eigensolution) of regular and local near-regular mechanical systems, the literature on vibration analysis of global near-regular mechanical systems ...

Volume 49, Issue 2 , December 2017, Pages 119-127
Abstract
In this paper we introduce the concept of $(1,2)^*$-sb-separated sets and $(1,2)^*$-soft b-connected spaces and prove some properties related to these \break topics. Also we disscused the properties of $(1,2)^*$-soft b- compactness in soft bitopological space Read MoreGroup $\{1, -1, i, -i\}$ Cordial Labeling of sum of $C_n$ and $K_m$ for some $m$
Volume 49, Issue 2 , December 2017, Pages 129-139
Abstract
Let G be a (p,q) graph and A be a group. We denote the order of an element $a \in A $ by $o(a).$ Let $ f:V(G)\rightarrow A$ be a function. For each edge $uv$ assign the label 1 if $(o(f(u)),o(f(v)))=1 $or $0$ otherwise. $f$ is called a group A Cordial labeling if $|v_f(a)-v_f(b)| \leq 1$ and $|e_f(0)- ...
