Title : Paired Domination of Certain Nanotubes
Country : Kwara State
Authors : A.S.Shanthi and A.Sajiya Merlin Mahizl

Abstract: A vertex subset \textit{D} of a graph \textit{G} is a dominating set if every vertex of \textit{G} is either in \textit{D} or is adjacent to a vertex in \textit{D}. The paired-domination problem on \textit{G} asks for a minimum-cardinality dominating set \textit{S} of \textit{G} such that the subgraph induced by \textit{S} contains a perfect matching. A set \textit{S} of vertices in \textit{G} is a total dominating set of \textit{G} if every vertex of \textit{V} is adjacent to some vertex in \textit{S}. In this paper we construct a minimum paired dominating set for \textit{H}-Naphtalenic Nanotorus, \textit{TUC}${}_{4}$\textit{C}${}_{8}$ (\textit{S}) nanotube and \textit{V}-phenylenic nanotube and hence we determine the total dominating set.

Keywords: Nanotubes, Perfect Matching, Paired Domination.

Title : Superior Julia Sets and Superior Mandelbrot Sets in SP Orbit
Country : India
Authors : Mandeep Kumari, Sudesh Kumari and Renu Chugh

Abstract: The aim of this paper is to generate new Superior Julia and Superior Mandelbrot sets for complex-valued polynomials such as quadratic, cubic and higher degree polynomials using SP orbit, which is an example of four-step iterative procedure. In this paper, we visualize the graphical images of Superior Julia sets and Superior Mandelbrot sets and analyze their patterns. It is surprising to see that a few Superior Mandelbrot sets take the shape of decorated coupled Urns (Kalash in Hindi language), a decorated coupled Lightening lamp (Diya in Hindi language) and beautiful scared patterns (Rangolies in Hindi language). We believe that our results generalize and extend the existing results in the literature of Fractal theory.

Keywords: Superior Julia set, Superior Mandelbrot set, Superior escape criterion, SP orbit, complex polynomials.

Title : Improvement On Operator Axioms And Fundamental Operator Functions
Country : P.R. China
Authors : Pith Xie

Abstract: The Operator axioms have been contructed to deduce number systems. In this paper, we slightly improve on the syntax of the Operator axioms and construct a semantics of the Operator axioms. Then on the basis of the improved Operator axioms, we define two fundamental operator functions to study the analytic properties of the Operator axioms. Finally, we prove two theorems about the fundamental operator functions and pose some conjectures. Real operators can give new equations and inequalities so as to precisely describe the relation of mathematical objects or scientific objects.

Keywords: Real Functions, Operator, Number System.

Title : Some New Combination Graphs
Country : India
Authors : G.V.Ghodasara and Mitesh J.Patel

Abstract: A graph $G=(V,E)$ with $p$ vertices and $q$ edges is said to be combination graph, if there exists an injection $f:V(G)\rightarrow{}\{1,2,\ldots,p\}$ such that the induced edge function $g_{f}:E(G)\rightarrow \mathbb{N}$ defined by $g_{f}(uv)=\frac{(f(u))!}{| f(u)-f(v)|! (f(v))!} ( f(u)>f(v))$, for every $uv$ $ \in $ $E(G)$ is injective. In this paper we prove that some cycle and wheel related graphs obtained with the use of graph operations are combination graph.

Keywords: Combination graph, prism graph, umbrella graph, wheel graph.

Title : Analyzing the Expectations of the Old Aged People Using Fuzzy Model
Country : India
Authors : A.Victor Devadoss and A.Lincy Amala Celine

Abstract: The advancement of technology and the necessities of the day to day life force the children to leave their parents to the old aged homes. Due to this process, the mushroom growths of old aged homes exist. And how far this home for aged satisfies the expectations of the parents and the responsibilities of the children are of major concern. The expectations of the elderly are very simple but not all children realize their importance or value their presence in their lives. The varying degree of acceptance of their ageing parents according to the human values is a valid criterion to study the expectations of the old aged people. The fuzzy logic serves as an appropriate tool to study the expectations as it is an unsupervised data. The problem of study is analyzed using the appropriate fuzzy model in this paper. The section one is of introductory nature. The second section gives the introduction to triangular fuzzy cognitive maps. The description of the problem is given in section three; and in the fourth section the model is adapted to the problem of study. The conclusion is derived in the final section.

Keywords: Triangular fuzzy number, linguistic variables, weightage and maximum weight.
