The Effect of Sensory Blind Zones on Milling Behavior in a Dynamic Self-Propelled Particle Model
Jonathan P. Newman, Hiroki Sayama
Emergent pattern formation in self-propelled particle (SPP) systems is extensively studied because it addresses a range of swarming phenomena which occur without leadership. Here w…
Orthonormal dilations of Parseval wavelets
Dorin Ervin Dutkay, Deguang Han, Gabriel Picioroaga +1
We prove that any Parseval wavelet frame is the projection of an orthonormal wavelet basis for a representation of the Baumslag-Solitar group We…
Binary quantization using Belief Propagation with decimation over factor graphs of LDGM codes
Tomas Filler, Jessica Fridrich
We propose a new algorithm for binary quantization based on the Belief Propagation algorithm with decimation over factor graphs of Low Density Generator Matrix (LDGM) codes. This a…
Computation of determinants using contour integrals
Klaus Kirsten, Paul Loya
It is shown how the pre-exponential factor of the Feynman propagator for a large class of potentials can be computed using contour integrals. This is of direct relevance in the con…
Unitary Representations of Wavelet Groups and Encoding of Iterated Function Systems in Solenoids
Dorin Ervin Dutkay, Palle E. T. Jorgensen, Gabriel Picioroaga
For points in real dimensions, we introduce a geometry for general digit sets. We introduce a positional number system where the basis for our representation is a fixed by…
