We consider a particle system on Z with finite state space and interactions of infinite range. Assuming that the rate of change is continuous and decays sufficiently fast, we introduce a perfect simulation algorithm for the stationary process. The basic tool we use is a representation of the infinite range change rates as a mixture of finite range change(More)
In Experiment 1, 10 pigeons were exposed to a successive symbolic matching-to-sample procedure in which the sample was generated by the pigeons' own behavior. Each trial began with both response keys illuminated white, one being the "correct" key and the other the "incorrect" key. The pigeons had no way of discriminating which key was correct and which(More)
Let α, β ∈ C r {0} and l ∈ N, odd with l ≥ 3. We determine all Hopf algebra quotients of the quantized coordinate algebra Oα,β(GLn) when α β is a primitive l-th root of unity and α, β satisfy certain mild conditions, and we caracterize all finite-dimensional quotients when αβ is not a root of unity. As a byproduct we give a new family of non-semisimple and(More)
Equivalence-equivalence responding (Eq-Eq) has become a behaviour analytic model of analogical reasoning. In previous works it was demonstrated that the exposition to a non-arbitrary relational task (facilitation procedure) improves performance in Eq-Eq tasks. In the present work we attempted to analyze the role of task components: arbitrary or nonarbitrary(More)
This paper presents a bridge between theory and hardware implementations of radio direction finding (RDF) techniques particularly Angle of Arrival (AoA) and radiolocalization technique namely Time Difference of Arrival (TDoA) in non-collaborative scenarios. It presents aspects that must be considered in the system design and performance tests, including(More)
In this paper an analysis of necessary and su¢cient conditions for persistency of excitation for a class of moored semisubmersibles with single-harmonic incoming wave is presented. The semiphysical model structure in 6 degrees of freedom is shown to contain a large number of parameters and states. The nonlinear system dynamics is able to produce chaotic(More)
