Title |
: | AHP Based on Trapezoidal Linguistic Fuzzy Preference Relation |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 7−14 |

**Abstract: ** Consistency is an important issue in any decision making problem. Lack of consistency yields to unreliable solution. This paper proposes Trapezoidal fuzzy linguistic preference relation to improve the consistency of Fuzzy analytic Hierarchy process. In this study using Trapezoidal fuzzy linguistic preference relation and using only n-1 pairwise comparisons, a pairwise comparison matrix is constructed. The matrix satisfies additive reciprocal property and consistency. The proposed method is applied to the example given in \cite{14} and the results are compared. This study provides the same ranking as in \cite{14} without much involvement of decision maker.

**Keywords: ** Fuzzy AHP, consistency, Trapezoidal fuzzy number, linguisticvariable, Decision making.

Title |
: | An Analytical Solution for Transient Asymmetric Heat Conduction in a Multilayer Elliptic Annulus and its Associated Thermal Stresses |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 29−42 |

**Abstract: ** A closed-form solution is presented for the transient heat conduction problem in the elliptic annulus with multiple layers in the radial direction, but time-independent volumetric heat sources in each layer. The solution is obtained applying an integral transform technique analogous to Vodicka's approach considering series expansion function in terms of an eigenfunction to solve the heat conduction partial differential equation in elliptical coordinates. The results are obtained as a series solution in terms of Mathieu functions and hold convergence test. The temperature and thermal stresses for the three-layer elliptic region have been computed numerically and exhibited in a graphical form, by using dimensionless values and therefore discussed.

**Keywords: ** Multilayer elliptic annulus, heat conduction, integral transform, thermal stresses.

Title |
: | Cordial Labeling for Star Graphs |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 51−54 |

**Abstract: ** Cordial labeling is used to label the vertices and edges of a graph with $\left\{ 0,1 \right\}$ under constraint, such that the number of vertices with label $0$ and $1$ differ by atmost $1$ and the number of edges with label $1$ and $0$ differ by atmost $1$. In this paper we prove that the two star graph $K_{1,m} \wedge K_{1,n} $ with a wedge in common is a cordial graph for all $m\geq1$ and $n\geq1$.

Title |
: | A Mathematical Model for Unemployment Control-An Analysis with and without Delay |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 83−93 |

**Abstract: ** The paper presented a mathematical model to control unemployment using dynamic system. In this process we consider the situation where job search is open for native unemployed and new migrant workers enter into the territory as unemployed. So, government of that territory feels more burden of unemployment and make efforts for creating new vacancies with the help of private sector. Also, we assume that native unemployed and new migrant workers both make efforts for self-employment. We studied the local stability of the non-negative equilibrium point with and without delay. Numerical simulation has been carried out to illustrate the analytical result.

**Keywords: ** Employed persons, unemployed persons, self-employment, migration, delay, dynamic variables.

Title |
: | Strong Edge Coloring of Some Classes of Unicyclic Graphs |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 95−98 |

**Abstract: ** Let \textit{G } be an undirected simple graph. A strong edge coloring of a graph \textit{G } is a function $f : E \to \{1, 2,\dots, k\}$ such that $f(e_{1} )\ne f(e_{2} )$ whenever $e_{1} $ and $e_{2} $ lie within distance 2 from each other. In other words, no two edges lie on a path of length 3 receive same colors. The smallest number of colors essential for strong edge coloring of a graph \textit{G } is entitled as strong chromatic index and is represented by $\chi '_{s} (G)$. In this paper, we investigate strong chromatic index of some classes of unicyclic graphs.

**Keywords: ** Strong edge coloring, strong chromatic index, unicyclic graph.

Title |
: | Edge Sum Index of a Graph in a Commutative Ring |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 121−131 |

**Abstract: ** Let $\Gamma(Z_{n})$ be a graph. A bijection $f:E(\Gamma(Z_{n})) \to Z^{+}$, where $Z^{+}$ is a set of positive integers is called an edge mapping of the graph $\Gamma(Z_{n})$. Now, we define, $F(v)=\Sigma\{f(e);$ e is incident on $v \}$ on $V(\Gamma(Z_{n}))$. Then, F is called the edge sum mapping of the edge mapping f. $\Gamma(Z_{n})$ is said to be an edge sum graph if there exists an edge mapping $f:E(\Gamma(Z_{n})) \to N^{+}$ such that f and its corresponding edge sum mapping. F on $V(\Gamma(Z_{n}))$ satisfy the following conditions: (i) F is into mapping to$ Z^{+}$. That is, $F(v) \in Z^{+}$, for every $v \in E(\Gamma(Z_{n}))$. (ii) If $e_{1},e_{2},\dots,e_{n} \in E(\Gamma(Z_{n}))$ such that $f(e_{1})+f(e_{2})+\dots f(e_{n}) \in Z^{+}$, then $e_{1},e_{2},\dots,e_{n}$ are incident on a vertex in $\Gamma(Z_{n})$. In this paper, we evaluated the edge sum index of some standard graphs in zero divisor graph.

Title |
: | Cordiality in the Context of Duplication in Helm and Closed Helm |

Volume, Issue, Year |
: | 6(1−A)(2018) |

Pages |
: | 139−145 |

**Abstract: ** Let $G = (V(G) , E(G))$ be a graph and let $\displaystyle f:V(G)\rightarrow \{0,1\}$ be a mapping from the set of vertices to \{0,1\} and for each edge $uv \in E$ assign the label $|f(u)-f(v)|$. If the number of vertices labeled with 0 and the number of vertices labeled with 1 differ by at most 1 and the number of edges labled with 0 and the number of edges labeled with 1 differ by at most 1, then $f$ is called a cordial labeling. We discuss cordial labeling of graphs obtained from duplication of certain graph elements in helm and closed helm.

Volume, Issue, Year |

Pages |
: | 155−162 |

**Abstract: ** In this paper, we first give solution to a general family of fractional differential equation involving Hilfer derivative operator and the fractional integral operator whose kernel is the $\overline{H}$-function. Next, we record here solutions of two fractional differential equations involving the function associated with Gaussian Model free energy and Polylogarithm function of order g as special cases of our main result. These special cases are believed to be new. On account of the general nature of\, $\overline{H}$-function in our main findings, the results derived earlier by Srivastava et al. \cite{47}, Srivastava and Tomovski \cite{11} and Tomovski et al. \cite{9} follow as special cases.
