On a Density for Sets of Integers
R. J. Cintra, L. C. Rêgo, H. M. de Oliveira +1
A relationship between the Riemann zeta function and a density on integer sets is explored. Several properties of the examined density are derived.
The Adaptive Mean-Linkage Algorithm: A Bottom-Up Hierarchical Cluster Technique
H. M. de Oliveira
In this paper a variant of the classical hierarchical cluster analysis is reported. This agglomerative (bottom-up) cluster technique is referred to as the Adaptive Mean-Linkage Alg…
Close expressions for Meyer Wavelet and Scale Function
V. VV. Vermehren, H. M. de Oliveira
Many continuous wavelets are defined in the frequency domain and do not have analytical expressions in the time domain. Meyer wavelet is ordinarily defined in this way. In this not…
Elliptic-cylindrical Wavelets: The Mathieu Wavelets
M. M. S. Lira, H. M. de Oliveira, R. J. Cintra
This note introduces a new family of wavelets and a multiresolution analysis, which exploits the relationship between analysing filters and Floquet's solution of Mathieu differenti…
On Filter Banks and Wavelets Based on Chebyshev Polynomials
R. J. Cintra, H. M. de Oliveira, L. R. Soares
In this paper we introduce a new family of wavelets, named Chebyshev wavelets, which are derived from conventional first and second kind Chebyshev polynomials. Properties of Chebys…
