Decision problem for shuffled genes
We consider a permutation-based model for the gene assembly process in ciliates. We give a procedure to decide whether a given micronuclear molecules may be assembled by using onl...

Micro-Macro Stack Systems: A New Frontier of Elementary Decidability for Sequential Systems
We define the class of micro-macro stack graphs, a new class of graphs modeling infinite-state sequential systems with a decidable model-checking problem. Micro-macro stack grap...

Formal Computation Independent Model of the Problem Domain within the MDA
The proposed approach called Topological Functioning Modeling for Model Driven Architecture (TFMfMDA) uses formal mathematical foundations of Topological Functioning Model. It intr...

The satisfiability threshold for randomly generated binary constraint satisfaction problems
Abstract. We study two natural models of randomly generated constraint satisfaction problems. We determine how quickly the domain size must grow with n to ensure that these models ...

Taking advantage of the Semantics of a Lesson Graph based on Learning Objects
Lesson graphs are composed of Learning Objects (LOs) and include a valuable amount of information about the content and usage of the LOs, described by the LO metadata. Graphs also ...
