A Study of Multigrid Methods with Application to Convection-Diffusion Problems
(UMIST (the University of Manchester Institute of Science and Technology), U.K., 1998-04-15)The work accomplished in this dissertation is concerned with the numerical solution of linear elliptic partial differential equations in two dimensions, in particular modeling diffusion and convection-diffusion. The ... -
Bounds on the number of isolates in sum graph labeling
(Discrete Mathematics, 2001)A simple undirected graph H is called a sum graph if there is a labeling L of the vertices of H into distinct positive integers such that any two vertices u and v of H are adjacent if and only if there is a vertex w with ... -
On two conjectures concerning vertex magic total labelings of generalized Petersen graphs
(Bulletins of ICA, 2001)A vertex-magic total labeling of a graph with $v$ vertices and $e$ edges is defined as a one-to-one map taking the vertices and edges onto the integers $1,2,\dots ,v+e$ with the property that the sum of the label on a ... -
Diregularity of digraphs of out-degree three and order two less than Moore bound
(Proceeding of 12th Australasian Workshop on Combinatorial Algorithms, 2001)It is easy to show that any digraph with out-degree at most $d \ge 2$, diameter $k \ge 2$ and order $n=d+d^2+\dots + d^k - 1$, that is, two less than Moore bound must have all vertices of out-degree $d$. In other words, ... -
Edge-magic total labelings of wheels, fans and friendship graphs
(Bulletins of ICA, 2002)An edge-magic total labeling on a graph with v vertices and e edges will be defined as a one-to-one map taking the vertices and edges onto the integers 1, 2, · · · , v+e with the property that the sum of the label on ... -

Vertex-antimagic total labelings of graphs
(Discussiones Mathematicae Graph Theory, 2003)In this paper we introduce a new type of graph labeling for a graph G(V;E) called an (a; d)-vertex-antimagic total labeling. In this labeling we assign to the vertices and edges the consecutive integers from 1 to |V| + |E| ... -

(a,d)-Edge-Antimagic Total Labelings of Caterpillars
(Lecture Notes in Computer Science, 2005)For a graph G = (V,E), a bijection g from V(G) ∪ E(G) into { 1,2, ..., ∣ V(G) ∣ + ∣ E(G) ∣ } is called (a,d)-edge-antimagic total labeling of G if the edge-weights w(xy) = g(x) + g(y) + g(xy), xy ∈ E(G), form an arithmetic ... -

Open Problems in the Construction of Large Directed Graphs
(Proceedings of the sixteenth Australasian Workshop on Combinatorial Algoritms, 2005-09-15)In this paper we consider the problem of how to construct directed graphs with given maximum out-degree and diameter. To deal with this problem, we describe several construction techniques. These fall into three broad ... -

Vertex-magic total labelings of disconnected graphs
(Journal of Prime Research in Mathematics, 2006)Let $G$ be a graph with vertex set $V=V(G)$ and edge set $E=E(G)$ and let $e=\vert E(G) \vert$ and $v=\vert V(G) \vert$. A one-to-one map $\lambda$ from $V\cup E$ onto the integers $\{ 1,2, ..., v+e \}$ is called {\it ... -
On the degrees of a strongly vertex-magic graph
(Discrete Mathematics, 2006)Let G=(V ,E) be a finite graph, where |V |=n2 and |E|=e1.A vertex-magic total labeling is a bijection from V ∪E to the set of consecutive integers {1, 2, . . . , n + e} with the property that for every v ∈ V , (v) +w∈N(v) ... -

Electropolymerisation and Characterisation of Doped-Polypyrrole as Humidity Sensor
(Indonesian Journal of Chemistry, 2006-07)A new type of sensing materials for humidity measurement has been developed based on conducting polymer polypyrrole synthesised from pyrrole by adding some dopant compounds, bromide and chloride, it is prepared by ... -
Super Edge-Antimagicness for a Class of Disconnected Graphs
(CIAO (Center for Informatics and Applied Optimisation), ITMS (School of Information Technology and Mathematical Science), University of Ballarat Australia., 2006-07-13)A graph G of order p and size q is called an (a,d)-edge-antimagic total if there exist a bijection f : V (G) U E(G) ---> {1, 2, ...., p + q} such that the edge-weights, w(uv) = f(u) + f(v) + f(uv); uv in E(G), form an ... -
