An Object Grammar for Column-Convex Polyominoes

Annals of Combinatorics, 2004
This articles shows an object grammar decomposition for the classes of column convex and directed column-convex polyominoes. The authors obtain the enumeration of these classes according to the semi-perimeter. In addition to that, they give an explanation of the algebraicity of the generating function for both classes.

Processing Learning Objects with Attribute Grammars

2009 Ninth IEEE International Conference on Advanced Learning Technologies, 2009
The services provided by learning object repositories are usually enabled by the processing of the metadata documents associated with these learning objects. This paper proposes a way to process these metadata documents, which are usually encoded in XML, through a framework called XLOP.

From object algebras to attribute grammars

ACM SIGPLAN Notices, 2014
Oliveira and Cook (2012) and Oliveira et al. (2013) have recently introduced object algebras as a program structuring technique to improve the modularity and extensibility of programs. We analyze the relationship between object algebras and attribute grammars (AGs), a formalism to augment context-free grammars with attributes.

Derivations in Object-Oriented Graph Grammars

2004
This work aims to extend the algebraic single-pushout approach to graph transformation to model object-oriented systems structures and computations. Graphs whose sets of nodes and edges are partially ordered are used to model the class hierarchy of an object-oriented system, making the inheritance and overriding relations explicit.
