Simplified stress and simplified silhouette coefficient to a faster quality evaluation of multidimensional projection techniques and feature spaces
(2015-09-18)
Several multidimensional projection techniques have been proposed in literature over the last years. The quality of those techniques can be evaluated based on the dimensionality reduction or the clusters quality. The first ...
Existence and uniqueness of solution for two one-phase Stefan problems with variable thermal coefficients
(Pergamon-Elsevier Science Ltd, 2019-08)
One dimensional Stefan problems for a semi-infinite material with temperature dependent thermal coefficients are considered. Existence and uniqueness of solution are obtained imposing a Dirichlet, a Neumann or a Robin type ...
Sign changes of Fourier coefficients of cusp forms supported on prime power indices
(World Scientific Publishing Co. Pte Ltd, 2014)
© World Scientific Publishing Company. Let f be an even integral weight, normalized, cuspidal Hecke eigenform over SL2(Z) with Fourier coefficients a(n). Let j be a positive integer. We prove that for almost all primes σ ...
A mathematical framework for image segmentation evaluation
(Universidade Federal de São Paulo (UNIFESP), 2020-06-30)
The analysis of similarity has interested the scientific community from the early 1900’s, with the pioneering work of Jaccard, to our very day. Many methods and algorithms for improving the correct quantification of ...

A characterization of degree two Siegel cusp forms by the growth of their Fourier coefficients
(Walter de Gruyter Gmbh, 2014)
We characterize all cusp forms among the degree two Siegel modular forms by the growth of their
Fourier coefficients. We also give a similar result for Jacobi forms over the group SL2(Z) Z(2).
