Bernstein Processes Associated with a Markov Process
A general description of Bernstein processes, a class of diffusion processes, relevant to the probabilistic counterpart of quantum theory known as Euclidean Quantum Mechanics, is given. It is compatible with finite or infinite dimensional state spaces and singular interactions. Although the relations with statistical physics concepts (Gibbs measure, entropy,. . . ) is stressed here, recent deve...
متن کاملApproximate Arc Length Parametrization
Current approaches to compute the arc length of a parametric curve rely on table lookup schemes. We present an approximate closed-form solution to the problem of computing an arc length parametrization for any given parametric curve. Our solution outputs a one or two-span Bézier curve which relates the length of the curve to the parametric variable. The main advantage of our approach is that we...
متن کاملRobust sensing of arc length
During arc welding, the arc heats and melts the workpiece as heat flux. When the welding current is given, the distribution and the intensity of the heat flux are determined by the length of the arc. The measurement and control of the arc length are fundamental in robotic and automated welding operations. Length of welding arc determines the distribution of the arc energy and thus the heat inpu...
متن کاملARC-LENGTH ESTIMATIONS FOR QUADRATIC RATIONAL Bézier CURVES COINCIDING WITH ARC-LENGTH OF SPECIAL SHAPES
In this paper, we present arc-length estimations for quadratic rational Bézier curves using the length of polygon and distance between both end points. Our arc-length estimations coincide with the arc-length of the quadratic rational Bézier curve exactly when the weight w is 0, 1 and∞. We show that for all w > 0 our estimations are strictly increasing with respect to w. Moreover, we find the pa...
متن کاملVariable Length Markov Chains
We study estimation in the class of stationary variable length Markov Ž . chains VLMC on a finite space. The processes in this class are still Markovian of high order, but with memory of variable length yielding a much bigger and structurally richer class of models than ordinary highorder Markov chains. From an algorithmic view, the VLMC model class has attracted interest in information theory ...
