In this paper we introduce two concepts related to resolvability and the metric dimension of graphs. The kth dimension of a graph G is the maximum cardinality of a subset of vertices of G that is resolved by a set S of order k. Some first results are

The 2-dimension of a Tree

Let x and y be two distinct vertices in a connected graph G. The x, ylocation of a vertex w is the ordered pair of distances from w to x and y, that is, the ordered pair (d(x, w), d(y, w)). A set of vertices W in G is x, y-located if any two vertic

Different-distance sets in a graph

Autor: Jason T. Hedetniemi, Stephen T. Hedetniemi, Renu C. Laskar, Henry Martyn Mulder

Publikováno v: Communications in Combinatorics and Optimization, Vol 4, Iss 2, Pp 151-171 (2019)

A set of vertices $S$ in a connected graph $G$ is a different-distance set if, for any vertex $w$ outside $S$, no two vertices in $S$ have the same distance to $w$. The lower and upper different-distance number of a graph are the order of a smallest

Atmospheric SO2 oxidation by NO2 plays no role in the mass independent sulfur isotope fractionation of urban aerosols

Autor: G. Bardoux, Pierre Cartigny, David Widory, D. Au Yang, C. Laskar, Nelly Assayag

Publikováno v: Atmospheric Environment. 193:109-117

Modern anthropogenic aerosols usually exhibit low but significant Δ33S signatures (−0.6 to 0.5‰) whose origin still remains unclear. While isotope fractionation factors associated with the oxidation of SO2 by O2+TMI (Transition Metal Ion), H2O2

A path-neighborhood graph is a connected graph in which every neighborhood induces a path. In the main results the 3-sun-free path-neighborhood graphs are characterized. The 3-sun is obtained from a 6-cycle by adding three chords between the three pa

High molecular weight waxes from Short Path Distillates of vacuum residue

Autor: Rajani Kumar Baruah, Swasti Munshi, Arun Borthakur, Narayan C. Laskar, Manoj Kumar Sarmah

Publikováno v: Fuel Processing Technology. 92:2360-2365

Short Path Distillates of vacuum residue (boiling above 545 °C) is taken as feedstock for this study. Wax from this fraction is separated by solvent extraction method using methyl iso-butyl ketone (MIBK) as solvent. Both wax and the feedstock are ch

Copolymers of bulky fumarate: synthesis and their properties

Autor: Shashi D. Baruah, Narayan C. Laskar, Diganta Sarmah

Publikováno v: Journal of Polymer Research. 18:225-233

The free radical copolymerization of di-n-docosyl fumarate with vinyl acetate and n-alkyl (meth)acrylates was carried out in toluene at 70°C using benzoyl peroxide as an initiator. 1H NMR and carbon analysis was used to determine the copolymer compo

Fall colouring of bipartite graphs and cartesian products of graphs

Autor: Jeremy Lyle, Renu C. Laskar

Publikováno v: Discrete Applied Mathematics. 157(2):330-338

The question of whether a graph can be partitioned into k independent dominating sets, which is the same as having a fall k-colouring, is considered. For k=3, it is shown that a graph G can be partitioned into three independent dominating sets if and
