  • k-Remainder Cordial Graphs 

    Ponraj, R.؛ Annathurai, K.؛ Kala, R. (University of Tehran, 2017-12-01)
    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.

  • New Algorithm For Computing Secondary Invariants of Invariant Rings of Monomial Groups 

    Rahmany, Sajjad؛ Basiri, Abdolali؛ Salehian, Behzad (University of Tehran, 2017-12-01)
    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 ...

  • A new indexed approach to render the attractors of Kleinian groups 

    Rosa, Alessandro (University of Tehran, 2017-12-01)
    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 ...

  • Normalized Tenacity and Normalized Toughness of Graphs 

    Javan, A.؛ Jafarpour, M.؛ Moazzami, D.؛ Moieni, A. (University of Tehran, 2017-12-01)
    In this paper, we introduce the novel parameters indicating Normalized Tenacity ($T_N$) and Normalized Toughness ($t_N$) by a modification on existing Tenacity and Toughness parameters.  Using these new parameters enables ...

  • A novel algorithm to determine the leaf (leaves) of a binary tree from its preorder and postorder traversals 

    Aghaieabiane, N.؛ Koppelaar, H.؛ Nasehpour, Peyman (University of Tehran, 2017-12-01)
    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 ...

  • Solving a non-convex non-linear optimization problem constrained by fuzzy relational equations and Sugeno-Weber family of t-norms 

    Ghodousian, Amin؛ Ahmadi, A.؛ Dehghani, A. (University of Tehran, 2017-12-01)
    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. ...

  • Some Properties of $(1,2)^*$-Soft b-Connected Spaces 

    Revathi, N.؛ Bageerathi, K. (University of Tehran, 2017-12-01)
    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- ...

  • Super Pair Sum Labeling of Graphs 

    Vasuki, R.؛ Arockiaraj, S.؛ Sugirtha, P. (University of Tehran, 2017-12-01)
    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 ...

  • Vibration Analysis of Global Near-regular Mechanical Systems 

    Shojaei, Iman؛ Rahami, Hossein (University of Tehran, 2017-12-01)
    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, ...

  • Vulnerability Measure of a Network - a Survey 

    Moazzami, Dara (University of Tehran, 2017-12-01)
    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 ...
