The syntax of modeling languages is usually defined in two steps. The abstract syntax identifies modeling concepts whereas the concrete syntax clarifies how these modeling concepts are rendered by visual and/or textual elements. While the abstract syntax i ...
Graph transformations are one of the best known approaches for defining model-to-model transformations in model-based software development. They are defined over the abstract syntax of source and target languages, described by metamodels. Since graph trans ...

Parser combinators provide an elegant way of writing parsers: parser implementations closely follow the structure of the underlying grammar, while accommodating interleaved host language code for data processing. However, the host language features used fo ...
Computational models have played a central role in the debate over language learnability. This article discusses how they have been used in different stances, from generative views to more recently introduced explanatory frameworks based on embodiment, cog ...
In this paper, the problem of face authentication using salient facial features together with statistical generative models is adressed. Actually, classical generative models, and Gaussian Mixture Models in particular make strong assumptions on the way obs ...
We consider from practical perspective the (generally undecidable) problem of checking equivalence of context-free grammars. We present both techniques for proving equivalence, as well as techniques for finding counter-examples that establish non-equivalen ...
Vernayaz, le 7 juillet 2014 ; ; Face à moi, déboulant des hauteurs, la puissante eau de Pissevache se heurte à la roche et chute. A l'inverse, “une tour minérale”, d'une solennelle immobilité, s'élève vers le ciel. Contenue au sein de l'éloquente montagne, ...
Unresolved indirect branch instructions are a major obstacle for statically reconstructing a control flow graph (CFG) from machine code. If static analysis cannot compute a precise set of possible targets for a branch, the necessary conservative over-appro ...
