Title : Einstein Criterion for Finsler Space With Special $(\alpha, \beta)$-Metrics
Volume, Issue, Year : 6(1−D)(2018)
Pages : 643−649

Abstract: Einstein-Finsler metrics are very useful to study geometric structure of spacetime and to build applications in theory of relativity. In this paper, we consider the special $(\alpha, \beta)$-metric $L=\mu \frac{\alpha^2}{\beta}+\nu \frac{\beta^2}{\alpha}$ and obtained the Riemann curvature. Then we obtained the necessary and sufficient condition for that $(\alpha, \beta)$-metric to be Einstein metric, when $\beta$ is a constant killing form. Finally, we proved that the above metric is Einstein if and only if it is Ricci flat.

Keywords: $(\alpha,\beta)$-metrics, Riemannian curvature, Ricci curvature, Einstein Finsler space.

Abstract: In 1965, the concept of total coloring was introduced by Behzad \cite{MB} and in 1967 he \cite{MG} came out new ideology that, the total chromatic number of complete graph and complete bi-partite graph. A total coloring of a graph $G$ is an assignment of colors to both the vertices and edges of $G,$ such that no two adjacent or incident vertices and edges of $G$ are assigned the same colors. In this paper, we have discussed the total coloring of splitting graph of Path, Cycle and Star graph. Also, we determine the total chromatic number of splitting graph of Path, Cycle and Star graphs.

Title : Square Divisor Cordial Labeling in the Context of Vertex Switching
Volume, Issue, Year : 6(1−D)(2018)
Pages : 687−697

Abstract: A square divisor cordial labeling of a graph $G$ with vertex set $V(G)$ is a bijection $f$ from $V(G)$ to $\{1,2,\ldots,|V(G)|\}$ such that an edge $e=uv$ is assigned the label $1$ if $[f(u)]^2|f(v)$ or $[f(v)]^2|f(u)$ and the label $0$ otherwise, then $|e_f(0)-e_f(1)|\leq1$. A graph which admits square divisor cordial labeling is called a square divisor cordial graph. In this research article we prove that the graphs obtained by switching of a vertex in bistar, comb graph, crown and armed crown are square divisor cordial. In addition to this we also prove that the graphs obtained by switching of a vertex except apex vertex in helm and gear graph are square divisor cordial

Abstract: The paper presents a classification and analysis of the results achieved using fuzzy logic to the model of transportation and traffic problems. In the recent years, research has been focused to estimating and techniques to help solve different engineering, management, control and computational problems. Natural systems teach us that very simple individual organisms can form system capable of performing highly tasks by dynamically interacting with each other. The main goal of the paper is to show how we can use fuzzy optimization approach when solving traffic and transportation. The fuzzy Ant system described in the paper represents an attempt to handle the uncertainty that sometimes exists in transportation problems.

Pages : 707−709

Abstract: In this paper, we introduce a new class of functions to be called countable KC and inversely countable KC functions. We study some relations between countable KC functions and inversely countable KC functions. We prove that if f is a continuous function from a space X to a Frechet, countable KC space Y, then $f(H)$ is closed in Y whenever H is a limit point compact set of X. It is also proved that if f is a countable KC function from a Frechet space X to a compact space Y, having closed point inverses, then f is continuous.

Title : Three-Dimensional Couette Flow Through Porous Medium Between Two Infinite Horizontal Parallel Porous Plates
Volume, Issue, Year : 6(1−D)(2018)
Pages : 719−730

Abstract: Aim of the paper is to investigate heat transfer through Couette flow of a viscous incrompessible fluid between two infinite horizontal parallel porous flat plates. The lower plate is stationary and the upper plate is moving with uniform velocity U subjected to transverse sinusoidal injection through lower plate and uniform suction through upper plate. Hence, the flow becomes three-dimensional due to fluid injection through lower plate. The governing equations of motion and energy are solved by regular perturbation technique and separation of variables technique. Velocity and temperature distributions are discussed numerically and shown through graphs. Nusselt number and coefficient of skin-friction at the plates are derived, discussed numerically and shown through graphs.

Keywords: Three-dimensionl, Couette flow, porous medium, skin-friction, Nusselt number.

Title : An Inventory Model for Deteriorating Items with Time Varying Demand and Shortages Using Fuzzy Environment
Volume, Issue, Year : 6(1−D)(2018)
Pages : 731−739

Abstract: Inventory in wider sense is defined as any idle resource of an enterprise. It is physical stock of goods, kept for the purpose of future affairs. Invention scheduling is a difficult task in industry with different operational constraints as well as strategic plan of the business revenue purpose and limit on finishing. To reduce the difficulties we introduce crisp and fuzzy model. Here fuzzy model consist of three methods gradient mean representation method, signed distance method, centroid method to deffuzify the total cost function with the help of triangular fuzzy number. The results obtained by these methods are compared with the help of a numerical example. Sensitivity analysis is also carried out to explore the effect of changes in the values of some of the system parameters. The aim of the study is to minimize the total cost function.

Keywords: Inventory, Deterioration, Shortages, Demand, Fuzzy variable, Triangular fuzzy number, Graded mean representation method, Signed distance method, Centroid method.

Abstract: The objective of this paper is to present the efficient and effective importance in productivity with the help of system repair and optimal maintenance. In fact the repair and maintenance is more concerning issue in the prevention of the losses due to breakdowns with in an enterprise. Queueing model is employed to analyze the system repair. Which describes the repair rate of the state is less or more. It is necessary to plan the activities to be carried out to ensure that the machines and plants of enterprises (production units) are working continuously. Therefore the gain is more important particularly when the production system grows as well as production quantity increases. Such study emphasis on optimal maintenance policy which is discussed in different cases. Availability of the system is examined by varying the various parameters.

Title : A Study on Sequencing Problem in Two Different Environments
Volume, Issue, Year : 6(1−D)(2018)
Pages : 835−839

Abstract: To represent uncertainty the fuzzy numbers are ideally suited. In the present paper, we have considered the sequence performance measurements and job mean flow time as fuzzy in nature. Using fuzzy technological values, we consider fuzzy sequencing problem in a different method. The concepts of Average High Ranking Method (AHRM) are considered. This idea is used to minimize the total cost in earliness (lateness) at fuzzy environment. It has been shown that fuzzy approaches are used to tackle uncertainty into processing of jobs very effectively. In the procedure to obtain completion time, fuzzy ranking technique and defuzzification methods are involved to compare the fuzzy numbers and to facilitate the effective deterministic algorithm to get the best solution. In the present work, we have compared Crisp sequencing problem and Fuzzy sequencing problem. To support our study, numerical examples are illustrated in this paper.

Keywords: Crisp number, fuzzy number, triangular fuzzy number, sequencing problem, fuzzy environment.}
