Wave Attenuation through Multiple Rows of Scatterers with Differing Periodicities
A solution method is proposed for calculating wave scattering by a multiple-row array in which the rows are permitted to have different periodicities. Each individual row contains ...

Reeb graphs: approximation and persistence
Given a continuous function f : X → IR on a topological space X, its level set f−1 (a) changes continuously as the real value a changes. Consequently, the connected components...

Monadic datalog over finite structures with bounded treewidth
Bounded treewidth and Monadic Second Order (MSO) logic have proved to be key concepts in establishing fixed-parameter tractability results. Indeed, by Courcelle's Theorem we ...
