This paper presents a variant of probabilistic roadmap algorithms that recently appeared as a promising approach to motion planning. We exploit a free-space structuring of the connguration space into visibility domains in order to produce small roadmaps. The algorithm has been implemented within a software platform allowing to address a large class of mechanical systems. Experiments show the ee...

Public Choice relies heavily on equilibrium analysis in its models of government failure. Austrians are suspicious of equilibrium analysis owing to its reliance on some variant of the perfect-knowledge assumption. To what extent then can Austrians consistently embrace public-choice descriptions of government failure? This paper argues that to maintain methodological consistency Public Choice sh...

The Prism is a new signal processing module which implements fully recursive, linear phase FIR filtering, so its computational cost fixed irrespective of filter length. also has negligible design cost. Recent work demonstrated how, using simple rules, chain six Prisms can create narrowband with arbitrary central frequency and bandwidth. In this paper, the technique applied to spectral analysis ...

Models of excitability fall into two broad categories: one with a sharp threshold, the other with a narrow but finite threshold region. In an attempt to clarify the notion, we have studied the application of two models of excitability to experiments on a variant of the BelousovZhabotinskii reaction in a well-stirred reactor. An interrupted separatrix model, which has a sharp threshold, is found...
