**Fuzzy Network Flow Problems**
* by Feblin C. Kennedy and S.U. Malini *

**Abstract:**

The concept of octagonal fuzzy numbers was introduced by the authors in an earlier paper [14]. In this paper, solution to network flow problems using octagonal fuzzy numbers are dealt with. viz, finding the shortest path of the network and project completion time. These problems were dealt with by several authors under different circumstances for different types of fuzzy numbers (to cite a few, [2] ,[3], [6], [7], [10]). In this paper the duration of activities are defined by octagonal fuzzy numbers which are more realistic and general in nature. Ranking using α–cut [14] is used to compare octagonal fuzzy numbers.

An algorithm is proposed to find fuzzy shortest path and fuzzy critical path of a project. Fuzzy shortest path, fuzzy critical path, fuzzy project completion time, fuzzy earliest start time, fuzzy earliest finish time, fuzzy latest start time, fuzzy latest finish time and fuzzy slack time for all activities are obtained as octagonal fuzzy numbers that captures the problem in a more realistic way.

**A Note on the Sparing Number of Generalised Petersen Graphs**
* by Sudev Naduvath, Chithra Kaithavalappil and Germina Augustine *

**Abstract:**

Let X denote a set of non-negative integers and P(X) be its power set. An integer additive set-labeling (IASL) of a graph G is an injective set-valued function ƒ : V (G) → P(X) – {φ} where induced function ƒ+ : E (G) → P(X) – {φ} is defined by ƒ+(uv) = ƒ(u) + ƒ(v), whereƒ(u) + ƒ(v) is the sumset of ƒ(u) and ƒ(v). The cardinality of the set-label of an element of G is said to be the set-indexing number of that element. A weak integer additive set-labeling is an IASL, in which the set-indexing number of every edge is equal to the set indexing number of at least one of its end vertices. The sparing number of a graph G is the minimum number of edges having set indexing number 1 required for G to admit weak IASL. In this paper, we discuss the sparing number of certain generalised Petersen graphs.

**Hope Algebra Action on Semialgebras**
* by M. Devendran and V. Selvan *

**Abstract:**

Let A be a k – semialgebra and let H be a k – Hopf algebra. In this paper we introduce the action of the Hopf algebra H on the semialgebra A. Also we study some ideal theoretic connection between the semialgebra A, its H – fixed subsemialgebra AH, by using the connection between ideals of the algebras of differences A of A, (AH) of AH.

**Estimation and Testing Procedures for the Reliability Functions of the Moore and Bilikam Family of Lifetime Distributions under Progressive type II right censoring**
* by Ajit Chaturvedi and Narendra Kumar *

**Abstract:**

In this article the Moore and Bilikam family of lifetime distributions is considered which covers many lifetime distributions as specific cases. Two measures of reliability R(t) = P(X>t) and P=P(X >X*) are considered. Point estimation and testing procedures are developed for R(t) and P under progressive type II right censoring. Three types of point estimators namely, uniformly minimum variance unbiased, maximum likelihood and invariantly optimal estimators are considered. Asymptotic confidence intervals are developed for the parameters θ and β. Testing procedures are also developed for the hypotheses related to different parametric functions. A comparative study of different methods of estimation is done through Monte Carlo simulation study.

**Disjoint Union Metric Spaces**
* by Meenakshi *

**Abstract:**

From the given metrics di on disjoint sets Xi, i = 1,2,3..., we define a new metric d on their union X so that it becomes a metric space. Further, we relate open spheres of the given sets to the open spheres of X so as to determine the structure of an open set in X. Finally, by using the inclusion mappings, we observe that the disjoint union topology of the topologies generated by di ’s on Xi ’s is the same as the topology generated by metric d on X.

**Constructions of Maximum Distance Separable Toeplitz Rhotrices over Finite Fields**
* by P. L. Sharma and S. Gupta *

**Abstract:**

Maximum Distance Separable (MDS) Matrices are used in block ciphers to achieve the maximum diffusion. Use of rhotrices increase the security as these are the representations of coupled matrices. We define Toeplitz rhotrix and construct the MDS rhotrices using Toeplitz rhotrices over finite fields.

**Some New Properties of k-Jacobsthal and k-Jacobsthal-Lucas Numbers**
* by Pankaj *

**Abstract:**

In this paper, some new properties of k-Jacobsthal and k-Jacobsthal-Lucas numbers are derived and proved by using matrices. The identities, which have been proved in this paper, are not encountered in the k-Jacobsthal and k-Jacobsthal-Lucas numbers literature.

**Prioritized Information Fusion Method for Uncertain Linguistic Information and its Application to Multiple Attribute Group Decision Making**
* by Rajkumar Verma *

**Abstract:**

In this paper, we investigate the uncertain linguistic multiple attribute group decision making (MAGDM) problems in which the attributes and decision-makers are in different priority levels. By combining the idea of quasi-arithmetic mean and prioritized weighted average (PWA) operator, we first propose a new aggregation operator called quasi-uncertain linguistic prioritized weighted average (QULPWA) operator for aggregating uncertain linguistic information. The properties of the new aggregation operator are studied in detail and their special cases are examined. Furthermore, based on the QULPWA operator, an approach to deal with multiple attribute decision-making problems under uncertain linguistic environments is developed. Finally, a practical example about the selection of university faculty is provided to illustrate the developed multiple attribute decision-making process.

**Restricted 2-Burst-Correcting Non-Binary Optimal Codes**
* by Vinod Tyagi and Tarun Lata *

**Abstract:**

Burst is the most common error in almost all communication channels and burst error correcting codes are developed to deal with such errors. According to Fire [7], a burst of length b or less is a vector whose all the non-zero components are confined to some b consecutive positions, the first and the last of which is non-zero. In this paper, we have introduced the idea of “restricted burst”, which is the modification of the definition of a burst. By a restricted burst of length b or less we mean a vector whose all the non-zero components are confined to some b consecutive positions, the first and last of which is nonzero with a restriction that all the non-zero consecutive positions contain same field element. For example in non-binary case for q = 3, n = 3 and b = 2, we have the following vectors of restricted burst of length 2 or less 110, 220, 011, 022, 100, 200, 010, 020, 001, 002. This idea may look hypothetical from practical point of view but we know it is true for binary case. Also the work may not have any practical utility at present but it is interesting from theoretical point of view. In this work, we present two construction techniques for optimal codes with respect to restricted burst of length 2 or less for linear as well as for byte oriented codes with redundancy r ≥3.

**Properties of Generalized k-Jacobsthal like Sequence Using Matrices**
* by Pankaj *

**Abstract:**

The Jacobsthal sequence has been generalized in many ways, some by preserving the initial conditions, others by preserving the recurrence relation. In this paper, we define a new generalization {Mk,n} n = 1,with initial conditions Mk,o = 2Mk,1= m+k, which is generated by the recurrence relation Mk,n+1 = kMk,n + 2Mk,n–1 for n ≥ 1, where k, m are integer numbers. Some new properties concerning this new generalization have been described using matrix algebra.

**Ideals in Gamma Semirings**
* by Tilak Raj Sharma And Shweta Gupta *

**Abstract:**

In this paper, the concept of ideals, k –ideals are introduced and their properties are studied. These results will be used to obtain some other new results such as the operations on ideals, the inclusion preserving bijection between the set of all ideals of a semiring R and the set of all ideals of Rn,n and other properties are studied. Moreover, ideals of Notherian and regular semirings are generalized.

**Local Metric Dimension of Families of Certain Graphs**
* by Fancy V F and V Jude Annie Cynthia *

**Abstract:**

Let G(V, E) be a graph with vertex set V and edge set E. Then a subset of V namely W is said to be a local metric basis of G, if for any two adjacent vertices u, v V\W, there exists a vertex w W, such that d(u, w) d(v,w). The minimum cardinality of local metric basis is called the local metric dimension of G and is denoted by l (G). In this paper we discuss the local metric basis of some simple graphs and investigate the local metric dimension of some families of Generalised Petersen graph. Also we discuss the local metric basis of Circulant graphs in this paper.

**Group {1,–1,i,–i}Cordial Labeling of Some New Graphs**
* by M.K. Karthik Chidambaram, S. Athisayanathan and R. Ponraj *

**Abstract:**

Let G be a (p,q)graph and A be a group. Let f :V (G) A be a function. The order of u A is the least positive integer n such that un = e. We denote the order of u by o(u). For each edge uv assign the label 1 if (o(f(u)),o(f(v))) = 1 or 0 otherwise. f is called a group A Cordial labeling if |vf(a) –vf(b)| 1 and |ef(0) –ef(1)| 1, where vf(x) and ef(n) respectively denote the number of vertices labeled with an element x and number of edges labeled with n(n = 0,1). A graph which admits a group A Cordial labeling is called a group A Cordial graph. In this paper we define group {1,–1,i,–i} Cordial graphs and prove that the Sunflower graph SFn, the graph Lotus inside a circle LCn, the Umbrella graph Un,n are all group {1,–1,i,–i} Cordial for all n. We further characterize Jewel graphs that are group {1,–1,i,–i} Cordial.
