Stable and controllable noise
We introduce a stable noise function with controllable properties. The well-known Perlin noise function is generated by interpolation of a pre-defined random number table. This table must be modified if user-defined constraints are to be satisfied, but modification can destroy the stability of the table. We integrate statistical tools for measuring the stability of a random number table with us...
متن کاملLocally controllable manipulation by stable pushing
When a polygonal object is pushed with line contact along an edge, the push is called stable if the object remains fixed to the pusher. The object is small-time locally controllable by stable pushing if, by switching among pushing edges, it can be pushed to follow any path arbitrarily closely. Because the pushes are stable by the frictional mechanics, pushing plans can be executed without posit...
متن کاملLocally controllable polygons by stable pushing
This paper characterizes polygons that are small-time locally controllableby stable pushing as a function of the polygon shape, the location of the center of friction, and the friction coefficient at the pushing contact. Such polygons can be pushed to follow any path arbitrarily closely, a useful property for planar manipulation. Because the pushes are stable, pushing plans can be executed with...
متن کاملA Robust Distributed Estimation Algorithm under Alpha-Stable Noise Condition
Robust adaptive estimation of unknown parameter has been an important issue in recent years for reliable operation in the distributed networks. The conventional adaptive estimation algorithms that rely on mean square error (MSE) criterion exhibit good performance in the presence of Gaussian noise, but their performance drastically decreases under impulsive noise. In this paper, we propose a rob...
متن کاملRandom Offset Curves and Surfaces with Controllable Noise
We introduce a novel parametric representation called ROPN (Random Offset Parametric representation with Noise), which is useful to represent a family of shapes sharing similar complex patterns often being able to be defined with the gradient noise functions. PORN is defined by replacing a static offset distance in a general offset with a gradient noise function. For example, PORN curve Cn(t) i...
