On Graceful Labelings of Trees

2011
A tree is a connected acyclic graph. A tree of n vertices is said to be graceful if the vertices can be assigned the labels {0, 1, 2, ..., n - 1} such that the absolute value of the differences in vertex labels between neighboring vertices generate the set consisting distinct values {1, 2, 3, ...,n-1}.

Graceful Labelings of Nearly Complete Graphs

Results in Mathematics, 2002
A graph with \(q\) edges is graceful, if we can assign to each vertex an integer in \(\{0, 1, \ldots, q\}\), such that all edges have a different value of the absolute difference of the labels of its endpoints. This paper investigates which graphs that are `nearly complete', or a complete multipartite graph, are graceful.

Real-graceful labellings: a generalisation of graceful labellings.

Ars Comb., 2011
Every graph can be associated to a characteristic exponential equation involving powers of (say) 2, whose unknowns represent vertex labels and whose general solution is equivalent to a graceful labelling of the graph. If we do not require that the solutions be integers, we obtain a generalisation of a graceful labelling that uses real numbers as labels.

On graceful and cordial labeling of shell graphs.

Ars Comb., 2011
A graceful labeling, an \(\alpha \)-labeling (called here \(\Delta \)-labeling), and a cordial labeling of yet another special class of graphs are provided. Unfortunately, the paper contains many typographical, grammatical and stylistic errors.

Graceful labeling based En (Grace) cryption and De (Grace) cryption

2013 IEEE International Conference ON Emerging Trends in Computing, Communication and Nanotechnology (ICECCN), 2013
In recent years, Encryption has fascinated extra responsiveness owing to the swift development in multimedia and network technologies where the data has to be shielded from unauthorized access. Image scrambling scheme provide protection for digital images.
