Title : Two Heterogeneous Service Queue With Second Optional Repair Subject to Reneging During Compulsory Vacation and Breakdown Time
Volume, Issue, Year : 6(3)(2018)
Pages : 7−14

Abstract: This paper deals with a single server batch arrival queue, two stages of heterogeneous service with different (arbitrary) service time distribution subject to random breakdowns followed by a repair and compulsory server vacations with general (arbitrary) vacation periods. After first stage service the server must provide second stage service. However after the completion of each second stage service the server will take compulsory vacation. The system may breakdown at random and it must be send to repair process immediately. If the server could not be repaired with first essential repair, subsequent repairs are needed for the restoration of the server. Both first essential repair and second optional repair times follow exponential distribution. We consider reneging to occur when the server is unavailable during the system breakdown or vacation periods. The steady state solutions have been found by using supplementary variable technique.

Keywords: Batch Arrivals, Breakdowns, Steady state, First essential repair, Second optional repair, Reneging.

The transformation graph $G^{---}$ of G is a simple graph with vertex set $V(G)\cup E(G)$ in which adjacency is defined as follows: (a) two elements in $V(G)$ are adjacent if and only if they are non-adjacent in $G,$ (b) two elements in $E(G)$ are adjacent if and only if they are non-adjacent in $G,$ and (c) an element of $V(G)$ and an element of $E(G)$ are adjacent if and only if they are non-incident in $G$. In this paper, we determine the chromatic number of Transformation graph $G^{---}$ for Complete, Wheel and Friendship graph.

Title : A Study on Magneto-thermodiffusive Wave Propagation in Dual-phase-lag Thermoelasticity with Temperature-dependent Properties
Volume, Issue, Year : 6(3)(2018)
Pages : 45−61

Abstract: The present paper is concerned with the analysis of magneto-thermodiffusive wave propagation in a homogeneous, isotropic, thermally and perfectly conducting elastic medium with temperature dependent mechanical properties. The formulation is established under the purview of dual-phase-lag thermoelasticity theory with diffusion. The modulus of elasticity is taken as a linear function of reference temperature. The resulting non-dimensional coupled equations are applied to a specific problem of a half-space whose surface is subjected to a time dependent mechanical shock. The analytical expressions for the displacement components, stresses, concentration and temperature field in the physical domain are obtained by employing normal mode analysis. Finally, numerical solution is carried out for copper material and corresponding graphs are plotted to illustrate and compare theoretical results. Discussions have been made to highlight the effects of phase lag parameters, temperature dependent modulus of elasticity, frequency and time on the physical fields. Some particular cases of interest have been deduced from the present investigation. The phenomenon of a finite speed of propagation is observed graphically for each field.

Keywords: Dual-phase-lag, Diffusion, Magneto-thermoelasticity, Temperature-dependent elastic modulus, Normal mode analysis.

Abstract: Let G be a $(p,q)$ graph. A graph G admits centered polygonal sum labeling if a one to one function $f:V(G)\rightarrow N$ (where $N$ is a set of all non-negative integers) that induces a bijection $f^+: E(G)\rightarrow\{\mathbf{_CP_k(1)},\mathbf{_CP_k(2)},\cdots ,\mathbf{_CP_k(n)}\}$ of the edges of G defined by $f^+(uv) = f(u) + f(v)$ for every $e=uv \epsilon E(G),$ where $\mathbf{_CP_k(1)},\mathbf{_CP_k(2)},\cdots ,\mathbf{_CP_k(q)} $, $k\ge3$ are the first q centered polygonal numbers.

In this paper we characterize some families of graphs such as Path, Comb, Star graph, Subdivision of star, Bistar, $S_{m,n,r}$, Coconut tree admit centered polygonal sum labeling.

Title : Transient Thermoelastic Analysis of a Multi-layered Oblate Spheroidal Shell with Internal Heat Generation
Volume, Issue, Year : 6(3)(2018)
Pages : 145−158

Abstract: The principal aim of this paper is to investigate the thermoelastic responses in a generalised oblate spheroid subjected time-independent volumetric heat sources in each layer and sectional heat supply on the inner and outer curved surfaces. The closed-form solution is obtained for transient temperature distributions by establishing Sturm-Liouville integral transform considering series expansion function in terms of an eigenfunction of Sturm-Liouville boundary value problem for the composite region consisting of multilayered composites in an oblate spheroidal coordinate system. The relations obtained in this paper can be applied to any arbitrary boundary and initial conditions to avoid structural failure due to thermal stress response. Some results which are derived using computational tools are accurate enough for the practical purpose were depicted graphically. The three-layer elliptic region has been computed numerically and exhibited in a graphical form, by using dimensionless values and therefore discussed.

Title : Evolutionary Vertical Size Reduction: A novel Approach for Big Data Computing
Volume, Issue, Year : 6(3)(2018)
Pages : 215−225

Abstract: Complexity of model based machine learning techniques depends mainly on the size of feature vector, so various feature selection and feature extraction methods are widely employed for size reduction. Although horizontal size reduction approaches can exponentially subside the complexity of learning algorithms, utilizing all instances to build and train any models can potentially be problematic. As illustration, not only problematic data can lead for over-fitting and over-generalization, but using noisy data can cause no proper decision makings. Furthermore, performance and complexity of instance/memory based classifiers (e.g. k-NN) are highly depends on train samples. In this paper, evolutionary vertical size reduction approach is introduced to identify and filter problematic and noisy data, not only for enhancing the performance and robustness of machine learning techniques but for ebbing the needs for remarkable system resources. To this end, genetic algorithms are proposed to label problematic instances in datasets. To evaluate the performance of proposed approach, benchmark classification datasets are employed to quantify the impacts of filtering noisy and problematic data in classification applications. Despite the fact that proposed vertical size reduction approach enhances machine learning techniques (mainly supervised learning methods), real world applications which contain big data would require remarkable system resources. To address this drawback, cloud computing frameworks (such as MapReduce on Hadoop) is recommended to make the proposed vertical size reduction more applicable for big data processing.

Title : Generalization of an Inequality with Sum of Fractions
Volume, Issue, Year : 6(3)(2018)
Pages : 227−230

Abstract: Cvetkovski introduced the inequality: $\frac{a^2+b^2}{a+b}+\frac{b^2+c^2}{b+c}+\frac{c^2+a^2}{c+a}\geq a+b+c$ in his book \textit{Inequalities: Theorems, Techniques and Selected Problems}. Starting from there we generalize this inequality to the case with non-negative real number exponents: $\frac{a^m+b^m}{a^n+b^n}+\frac{b^m+c^m}{b^n+c^n}+\frac{c^m+a^m}{c^n+a^n}\geq a^{m-n}+b^{m-n}+c^{m-n}$ for $m\geq n$. Moreover, we also discuss the order of the sum of fractions when the exponents in the fractions change, and prove the inequality $\frac{a^m+b^m}{a^n+b^n}+\frac{b^m+c^m}{b^n+c^n}+\frac{c^m+a^m}{c^n+a^n}\geq\frac{a^{m-l}+b^{m-l}}{a^{n-l}+b^{n-l}}+\frac{b^{m-l}+c^{m-l}}{b^{n-l}+c^{n-l}}+\frac{c^{m-l}+a^{m-l}}{c^{n-l}+a^{n-l}}$ for real numbers $m\geq n\geq l\geq 0$. Versions of the two inequalities with $k$-variables are also examined.

Title : Analysis of Two-Echelon Inventory System With Two Demand Classes With Direct Demand
Volume, Issue, Year : 6(3)(2018)
Pages : 261−271

Abstract: This paper deals with a continuous review two-echelon inventory system with two demand classes.. The demand at retailer is of two types. The First type of demand is usual single unit and the second type is of bulk or packet demand. The arrival distribution for single and packet demands are assumed to be independent Poisson with rates $\lambda_{1}\ (>0)$ and $\lambda_{q}\ (>0)$ respectively. The model permits a direct demand of distributor which follows Poisson with rate $\lambda_{d}\ (>0) $. The operating policy at the lower echelon for the (s, S) that is whenever the inventory level drops to `\textbf{s'} on order for $Q = (S-s)$ items is placed, the ordered items are received after a random time which is distributed as exponential with rate $\mu>0$. We assume that the demands occurring during the stock-out period are lost. The retailer replenishes the stock from the distributor which adopts $(0, M)$ policy. The objective is to minimize the anticipated total cost rate by simultaneously optimizing the inventory level at all the equations. The joint probability disruption of the inventory levels at retailer and the distributor are obtained in the steady state case. Various system performance measures are derived and the long run total expected inventory cost rate is calculated. Several instances of numerical examples, which provide insight into the behavior of the system, are presented.

Title : Exploring the Properties of m-bonacci Sequences
Volume, Issue, Year : 6(3)(2018)
Pages : 357−363

Abstract: This paper formalized the definition of an m-bonacci sequence, a generalization of the more commonly known Fibonacci and Tribonacci sequences. Four theorems are then introduced to discuss the properties of these sequences and establish a relationship between the terms of the sequence with the related characteristic equation. A generating function is obtained that expresses all the terms of the sequence, and with an elaborate analysis of the function the last theorem-to limit the ratio of consecutive terms to 2-is proved using an alternate method.

Keywords: Number theory, Fibonacci sequences, Mathematical Induction, Generating Functions.

Title : A Study on Gender Inequality in Education by Using Fuzzy Associative Memories
Volume, Issue, Year : 6(3)(2018)
Pages : 365−368

Abstract: Education plays a major role for the development of human beings to recognize their rights in terms of social, political and economic growth of the country. More than one-third of women around the world who are illiterate are Indian women. Thus, the inequalities of women in education not only affects the women's lives but also on the economic developments of the country. This papers explores how Gender inequality in education affects the development of the society by using Fuzzy logic as it helps to study the uncertainties with the help of appropriate Fuzzy model.Here Section one deals with Introduction. Section two gives definitions of Fuzzy Associative Memories. Section three description of the problem is explained. Section four deals with the adaptation of the problem. Ultimately section five reveals the conclusion.

Keywords: Fuzzy Associative Memories, Gender inequality, Education.
