This paper presents two stochastic filters considering autoregressive models of first and second order for parameter estimation and system identification. Each model is applied to a reference of the corresponding order and their recursive and non-recursive estimation results are compared; obtaining their error functional values to determine their performance. Due to the recursive methods give b...

We investigate both first-order topology, as realized through Haldane's model, and second-order implemented an additional Kekul\'e distortion, on the honeycomb lattice. The interplay competition of terms result in a phase diagram at half-filling which contains 12 distinct phases. All phases can be characterized by first Chern number or quantized ${\mathbb{Z}}_{Q}$ Berry phase. Highlights includ...

Purpose – The purpose of this paper is to explore the two subjects, cybernetics and design, in order to establish and demonstrate a relationship between them. It is held that the two subjects can be considered complementary arms of each other. Design/methodology/approach – The two subjects are each characterised so that the author’s interpretation is explicit and those who know one subject but ...

Consistent answers to a query from an inconsistent database are answers that can be simultaneously retrieved from every possible repair; and repairs are consistent instances that minimally differ from the original instance. Database repairs can be specified as the stable models of a disjunctive logic program. In this paper we show how to use the repair programs to transform the problem of consi...
