Title : Cordial Labeling of Double Antenna One Point Union Graphs
Volume, Issue, Year : 6(1−E)(2018)
Pages : 853−858

Abstract: We discuss graphs of type $G^{(k)}$ i.e. one point union of k-copies of G for cordial labeling. We take G as double tail graph of $C_{3}$. i.e. $G= tail(C_{3},2-P_{m})$. In $tail(C_{3},2-P_{m})$ graph double paths are attached at same point of $C_{3}$. We restrict our attention to $m = 2, 3, 4 $. Further we consider all possible structures of $G^{(k)}$ by changing the common point on G and obtain non-isomorphic structures. We show all these structures as cordial graphs. This is called as invariance of different structures under cordial labeling.

Keywords: Cordial, labeling, tail graph, invariance, path, one point union.

Title : Cloud Load Prediction for Multiuser Mixed Distribution Task Length and Task Arrival Scenario
Volume, Issue, Year : 6(1−E)(2018)
Pages : 877−887

Abstract: In the mathematics queuing theory is one of the fields which can be used for finding solutions of a wide range of practical problems. One of the recently growing application of this field is in computer network traffic management. In this paper we applied the queuing theory for the prediction of job request queue in a cloud network where the job requests are arriving through a single queue and are combination of jobs generated by a number of users with each having the different job request patterns (distribution function). The growing adaption of cloud systems, resulting in excessive loading of cloud servers. Since the cloud is designed to provide different resources as service over the internet. The cloud user requests required resources from the cloud and the cloud serves these requests by forming virtual machines and allotting it some the resources from cloud resource pool. The resources allotted to VMs depends upon the requirements of the task and guaranteed QoS of the cloud. Once the task is completed these VM’s can either be dissolved to utilize its resources for another VM or can be suspended for later utilization and saving power. The creation of a VM may take several seconds while activation of a suspended VM is also required some time, which may ultimately cause sluggish response and latency in cloud response. Such situations can be avoided by predicting the upcoming task requirements. The knowledge of upcoming tasks can be used to decide whether VM’s needs to keep alive, suspended or dissolved to efficiently utilize the resources, saving power and serve the requests with minimum latency. The prediction of task requirements is a difficult job especially when the task requests are generated by different users and each user may follow different distribution function. This paper presents the HMM-based prediction model for such conditions and evaluates its performance.

Title : A Sequence of Complete Cosmic Scenario from Inflation to Late Time Acceleration with Adiabatic Particle Creation
Volume, Issue, Year : 6(1−E)(2018)
Pages : 895−902

Abstract: In the background of a flat FRW model, we assume the non-equilibrium thermodynamical process to be isentropic so that the entropy per particle does not change and consequently the dissipative pressure can be expressed linearly in terms of the particle creation rate. This paper deal with the Friedman equations and by a sequence of proper choices of the particle creation rate as a function of the Hubble parameter, it is possible to show a continuous cosmic evolution from inflation to late time acceleration.

Keywords: Particle creation, dissipative pressure, entropy production, isentropic process, unified cosmic evolution.

Title : Analysis of Langmuir-Hinshelwood Kinetics Model for Photocatalytic Degradation of Aqueous Direct Blue 71 Through Analytical Expression
Volume, Issue, Year : 6(1−E)(2018)
Pages : 903−913

Abstract: An analysis of the Langmuir-Hinshelwood expression is presented for the photocatalytic degradation of Aqueous Direct Blue 71. This analysis contains a nonlinear term that explains the kinetics of the heterogeneous catalytic processes. In this paper, we obtain approximate analytical solutions for the nonlinear equation by employing the Perturbation-Iteration Algorithms (PIA). The main objective is to propose an analytical method of solution, which do not require small parameters and avoid linearization and physically unrealistic assumptions. Furthermore, in this work decolorization efficiency (DE\%) and the numerical solution to the problem is also reported using MATLAB program. The analytical results are compared with the numerical and limiting case result. The obtained results are valid for the whole solution domain. A good agreement between the theoretical predictions and numerical results is observed. Langmuir-Hinshelwood model is analyzed with the help of analytical result for the different values of $H_{2}O_{2}$ and $SiO_{2}$-NP to describe photocatalytic degradation of the dye.

Title : On Commutativity of Assosymmetric Rings With Some Identities
Volume, Issue, Year : 6(1−E)(2018)
Pages : 915−924

Abstract: In this paper we present some results on assosymmetric rings satisfying some identities. A non-associative ring is defined as a nilpotent if there exists $k \geq0$ such that any product having k elements is zero. A ring is solvable if the chain of sub rings $S \supseteq S^{2} \supseteq (S^{2})^{2} \supseteq \dots$ reaches zero in a finite number of steps. While solvable associative rings are obviously nilpotent, solvable alternative rings need not be nilpotent [1].

Title : Post Optimality Analysis in Fuzzy Multi Objective Linear Programming
Volume, Issue, Year : 6(1−E)(2018)
Pages : 925−937

Abstract: Models of linear programming problems with fuzzy constraints are well known in the current literature. In this paper, the post optimality analysis (POA) of a given fuzzy efficient solution in a general fuzzy multi-objective linear programming (FMOLP) problem is considered. The POA determines the largest sensitivity region of changes in the input data the fuzzy efficient solution of FMOLP problem remains unchanged. For this reason, three cases are considered separately: changing in one objective function coefficient (the change in one of objective functions' coefficient), objective function removal and objective function addition. Each case is illustrated by a numerical example.

Keywords: Fuzzy multi objective linear programming, Fuzzy efficiency, Pareto optimality, Post optimality analysis.

Title : Two-Fluid Dark Energy Cosmological Models In Saez-Ballester Theory of Gravitation
Volume, Issue, Year : 6(1−E)(2018)
Pages : 989−995

Abstract: The present paper deals with cylindrically symmetric metric in the form of Marder (1958) with Saez-Ballester theory of gravitation in the presence of perfect fluid and dark energy. In order to obtain the deterministic solution of the field equations we have assumed that the expansion scalar in the model is proportional to the Eigen value of the shear tensor. We have also assumed that the two sources, here the perfect fluid and dark energy interact minimally with separate conservative parts of their energy momentum tensors together with the constant EoS parameter of the perfect fluid. The role of the dark energy in the present model with variable equation of state parameter is studied more in detail. Some physical properties of model are also discussed.

Keywords: Cylindrically symmetric metric, perfect fluid and dark energy as the source, Saez-Ballester theory of gravitation.

Title : $E_k$-Super Vertex Magic Labeling of Graphs
Volume, Issue, Year : 6(1−E)(2018)
Pages : 1005−1012

Abstract: Let $G$ be a graph with $p$ vertices and $q$ edges. An $E_k$-super vertex magic labeling ($E_k$-SVML) is a bijection $f: V(G) \cup E(G)\rightarrow \{ 1,2 , \ldots, p + q \}$ with the property that $f(E(G)) = \{ 1,2,\ldots, q \}$ and for each $v \in V(G)$, $f(v) + w_k(v) = M$ for some positive integer $M$. For an integer $k \geq 1$ and for $v \in V(G)$, let $w_k(v) = \sum\limits_{e \in E_k(v)}f(e)$, where $E_k (v)$ is the set of all edges which are at distance at most $k$ from $v$. The graph $G$ is said to be \textit{$E_k$-regular} with regularity $r$ if and only if $\left| E_k(e) \right| = r$ for some integer $r \geq 1$ and for all $e \in E(G)$. A graph that admits an $E_k$-SVML is called $E_k$-super vertex magic ($E_k$-SVM). This paper contain several properties of $E_k$-SVML in graphs. A necessary and sufficient condition for the existence of $E_k$-SVML in graphs has been obtained. Also, the magic constant for $E_k$-regular graphs has been obtained. Further, we establish $E_2$-SVML of some classes of graphs such as cycles, complement of cycles, prism graphs and a family of circulant graphs.

Keywords: $E_k$-super vertex magic labeling, $E_k$-regular graphs, circulant graphs.

Title : Analysis of Preemptive Priority Retrial Queueing System with Starting Failure, Modified Bernoulli Vacation with Vacation Interruption, Repair, Immediate Feedback and Impatient Customers
Volume, Issue, Year : 6(1−E)(2018)
Pages : 1013−1023

Abstract: This paper considers $M^{[X_{1} ]} ,M^{[X_{2} ]} /G_{1} ,G_{2} /1$ general retrial queueing system with priority services. The server serves two types of customers and follows the pre-emptive priority rule subject to starting failure, repair, immediate feedback, orbital search and modified Bernoulli vacation with vacation interruption. High priority customes are considered as a feedback customer. After vacation completion, service completion and repair completion if there is no high priority customers present in the system the server may go for orbital search or remains idle. The high priority customer may renege the queue and the low priority customers may balk the orbit. Retrial time, service times, repair time and vacation time are assumed to be arbitrarily distributed. Various performance measures are derived and numerical results are presented. Using the supplementary variable technique, the steady-state distributions of the server state and the number of customers in the orbit are obtained. Further, some particular cases of interest are discussed. Finally, numerical illustrations are provided.

Keywords: Priority queueing systems, Starting failure, Modified Bernoulli vacation, Vacation interruption, Immediate feedback, Reneging, Balking.

Title : Degrees and Degree Sequences of PAN Critical Graphs
Volume, Issue, Year : 6(1−E)(2018)
Pages : 1025−1028

Abstract: A pseudo-complete coloring of a graph G is an assignment of col¬ors to the vertices of G such that for any two distinct colors, there exist adjacent vertices having those colors. The maximum number of colors used in a pseudo-complete coloring of G is called the pseudo-achromatic num¬ber of G and is denoted by $\psi_s (G)$. A graph G is called edge critical if $\psi_s (G-e)< \psi_s (G)$ for any edge e of G. A graph G is called vertex critical if $\psi_s (G-v)< \psi_s (G)$ for every vertex v of G. These graphs are generally called as pseudo-achromatic number critical graphs (shortly as PAN Critical graphs). In this paper, we investigate the properties of these critical graphs.

Keywords: Pseudo-complete coloring, Pseudo-achromatic number, k-edge critical graph, k-vertex critical graph.

Title : Global Cototal Domination in Graphs
Volume, Issue, Year : 6(1−E)(2018)
Pages : 1051−1055

Abstract: A set of vertices D in a graph G is a dominating set, if each vertex of G is dominated by some vertices of D. The domination number $\gamma(G)$ is the minimum cardinality of a dominating set of G. A dominating set D of a graph G is a global dominating set if D is also a dominating set of $\bar{G}$. The global domination number $\gamma_g(G)$ is the minimum cardinality of a global dominating set of G. A dominating set D of a graph G is a cototal dominating set if the induced sub graph, $\langle V-D\rangle$ has no isolated vertices. The cototal domination number $\gamma_{cot}(G)$ is the minimum cardinality of a cototal dominating set of G. In this paper we introduce a new concept, the global cototal domination number $\gamma_{gcot}(G)$. A dominating set D of a graph G is a global cototal dominating set if D is both a global dominating set and a cototal dominating set. The global cototal domination number $\gamma_{gcot}(G)$ is the minimum cardinality of a global cototal domination set of G. We initiate the study of global cototal domination number and present bounds and some exact values of $\gamma_{gcot}(G)$ for some classes of graphs.

Title : Diffusion-Thermo Effects on Heat and Mass Transfer of Non-Newtonian Power Law Fluid past a Porous Flat Plate with Chemical Reaction
Volume, Issue, Year : 6(1−E)(2018)
Pages : 1077−1083

Abstract: The diffusion-thermo effects on heat and mass transfer of a laminar boundary layer flow of a non-Newtonian power law fluid past a porous flat plate in the presence of magnetic field with chemical reaction effects have been considered. A suitable set of dimensionless variables is used and similar equations governing the flow are obtained. The resulting the non-linear ordinary differential equations are first linearised using Quasi-linearization technique and then an adequate implicit finite difference scheme is employed to obtain a numerical solution for the ordinary differential equations. The Representative results for the velocity, temperature and concentration profiles illustrating the influence of various governing parameters are presented and discussed. Temperature rises with increase in Dufour number and the effect of Chemical reaction parameter is to decrease the concentration of the fluid.

Keywords: Non-Newtonian fluid, power law index, Dufour number, Chemical reaction parameter, Finite Difference method.
