Title : Performance Analysis of a Cold Standby System with fault Detection and Arrival Time of Server Subject to Imperfect Coverage
Country : India
Authors : Ashish Kumar || Monika Saini || Devesh Kumar Srivastava

Abstract: The main aim of present paper is to analyse the performance measures of a standby system by using the concept of arrival time of server, repair, imperfect coverage, detection and replacement. A single repair facility is provided to the system as and when required. The repairman takes some time to conduct the repair services. Upon failure of the unit repairman first detect the failed unit to check the feasibility of repair and replacement in case fault is not completely coverage. The repair, replacement, detection and arrival time of the repairman are considered as arbitrary distributed while failure rate is taken as negative exponential distributed. The failure time of the unit is exponentially distributed while the distribution of repair times, replacement time and recovery time of the unit follows arbitrary distribution. Various recurrence relations for reliability, MTSF, availability and profit function are derived using semi-Markov process and regenerative point technique. Graphs for availability and profit function are drawn with respect to failure rate.

Keywords: Standby System; Arrival Time of Server; Imperfect Coverage; Replacement and Performance Measures.

Title : New results on edge pair sum graphs
Country : India
Authors : P.Jeyanthi || T.Saratha Devi

Abstract: Let $G$ be a (p,q) graph. An injective map $f:E(G)\rightarrow\left\{\pm1,\pm2,\cdots,\pm q \right\}$ is said to be an edge pair sum labeling if the induced vertex function $f^{*}:V(G)\rightarrow Z-\left\{0\right\}$ defined by $f^{*}(v)= \mathop\sum\limits_{e\epsilon E_{v}}f\left(e\right)$ is one- one where $E_{v}$ denotes the set of edges in $G$ that are incident with a vertex $v$ and $f^{*}(V(G))$ is either of the form $\left\{\pm k_{1},\pm k_{2},\cdots,\pm k_{\frac{p}{2}}\right\}$ or $\left\{\pm k_{1},\pm k_{2},\cdots,\pm k_{\frac{p-1}{2}}\right\}$ $\bigcup$$\left\{\pm k_{\frac{p+1}{2}}\right\}$ according as $p$ is even or odd. A graph that admits an edge pair sum labeling is called an edge pair sum graph. In this paper we prove that the graphs jelly fish, Y-tree, theta, the subdivision of spokes in wheel $SS(W_{n})$, $P_{m} + 2K_{1}$, $C_{4} \times P_{m}$, $P_{n}\odot K^{c}_{m}$ admit edge pair sum labeling.

Keywords: Edge pair sum labeling, edge pair sum graph, jelly fish, Y-tree, theta graph, subdivision of spokes in wheel.

Title : Some Bounds on Co-isolated Locating Domination Number
Country : India
Authors : S.Muthammai || N.Meenal

Abstract: Let G (V, E) be a simple, finite and undirected connected graph. A non empty set S V of a graph G is a dominating set, if every vertex in V S is adjacent to atleast one vertex in S. A dominating set S V is called a locating dominating set, if for any two vertices v, w V S, N(v)S N(w)S. A locating dominating set S V is called a co isolated locating dominating set (cild set), if there exists atleast one isolated vertex in . The co isolated locating domination number gcild is the minimum cardinality of a co isolated locating dominating set. In this paper, some bounds on co isolated locating domination number are obtained. Also minimal cild sets are characterized. Further the graphs for which gcild to be p 2 are obtained.

Keywords: Dominating set, locating dominating set, co isolated locating dominating set, co isolated locating domination number.

Moreover we establish that it is the largest ideal with respect to some property on the operations.

Title : Study of Anomalous Behavior of blood flow in Capillary Surrounded by tissue
Country : India
Authors : Rekha Bali || Swati Mishra || P.N.Tandon

Abstract: A Mathematical model for the two phase flow of blood in a narrow capillary surrounded by the tissue has been presented in this paper. We have developed the earlier two phase models of blood flow in capillaries into a model of capillary-tissue fluid exchange system by including porous tissue enclosing the capillary. Blood is not a homogeneous fluid, It is a suspension. The suspended blood cells accumulate at the axis in response to flow, resulting in a blunting of the velocity profile near the axis in contrast to the parabolic profile observed in homogeneous fluids. Earlier models have not included the effect of fluid exchange in between the capillary and the tissue while microtubes or capillaries are surrounded by tissue. Therefore, our aim is to include effects of permeability of the tissue with two phase flow of blood in narrow tubes. The model consists of a core region of suspension of all erythrocytes and a peripheral layer of plasma surrounding the core. The governing partial differential equations have been solved by using mathematical and computational techniques. Analytical results, in the proposed model for apparent viscosity, Bluntness and ratio of capillary hematocrit with discharge hematocrit values have been presented and discussed through graphs for various values of parameters and with their axial variations.

Keywords: Anomalous behavior, Apperant viscosity, Bluntness, Capillary-tissue fluid exchange.

Title : Algorithmic Aspects of k-Geodetic Sets in Graphs
Country : India
Authors : Dr.A.Anto Kinsley || K.Karthika

Abstract: Let \textit{G} be a connected graph of order \textit{p} $\mathrm{\ge}$ 2. We study about the geodetic sets and \textit{k}-geodetic sets of \textit{G}. We study link vectors and prove a theorem to develop an algorithm to find the \textit{k}-geodetic sets. Initially we study algorithms to find the closed interval between any two vertices of \textit{G} and to find it's link vectors. In this paper we present two algorithms to check whether a given set of vertices is a \textit{k}-geodetic set and to find the minimum \textit{k}-geodetic set of \textit{G}.

Keywords: Graph, geodetic set, k-geodetic set, graph algorithms.

Title : Radiation effects of MHD Oscillatory Rotation Flow through a Porous Medium bounded by two Vertical Porous Plates in the Presence of Hall Current and Dufour effect with chemical reaction
Country : India
Authors : Dr.K.Balamurugan || Mr.R.Karthikeyan

Abstract: In this Article, Radiation Effects of Oscillatory flow through a porous medium bounded by two vertical porous plates in the presence of Hall Current and Dufour Effect with homogeneous First order chemical reaction under the influence of uniform magnetic field is studied. One plate is kept stationary and another plate is oscillating with uniform velocity. The Plates are subjected to the constant injection and suction velocities respectively. The basic governing equations of the problem are transformed into a system of non dimensional differential equations, which are solved analytically by using Perturbation techniques. The dimensionless Velocity, temperature and concentration profiles are displayed graphically showing the effects of fluid flow for the different values of the parameters involving in this problem like Hartmann Number M, Radiation Parameter F, Grashof Number Gr, chemical reaction parameter R, Dufour effects Du, It is observed that increase of Permeability parameter K, Hall Parameter m, shows the increase effects of Velocity profile. The increase of chemical reaction parameter R shows decrease effects of concentration.

Keywords: Hall Current, Dufour Effect, Chemical Reaction, MHD, Porous Medium, Oscillatory flow, Heat Source, Rotation effect.

Title : Study of Non-Newtonian Herschel-Bulkley Model through Stenosed Arteries
Country : India
Authors : Vipin Kumar Verma

Abstract: The present paper contains a study of blood flow in arteries from the heart keeping in view the nature of blood flow circulation in human body. Blood has been represented by a non-Newtonian fluid obeying Herschel-Bulkley equation. The usual blood flow in arteries is obstructed by abnormal tissue development on the walls of these vessels, called as stenosis in bio transport system.Integral method has been used to solve the unsteady non linear Navier- Stokes equations in cylindrical coordinates system governing flow assuming axial symmetry under laminar flow condition. The effect of the stenosis geometry is assumed to overshadow any influence of wall distensibilty.

Keywords: Artery, stenosis, distensibility, laminar flow.
