Rounded Hartley Transform: A Quasi-involution
R. J. Cintra, H. M. de Oliveira, C. O. Cintra
A new multiplication-free transform derived from DHT is introduced: the RHT. Investigations on the properties of the RHT led us to the concept of weak-inversion. Using new construc…
Infinite Sequences, Series Convergence and the Discrete Time Fourier Transform over Finite Fields
R. M. Campello de Souza, M. M. Campello de Souza, H. M. de Oliveira +1
Digital Transforms have important applications on subjects such as channel coding, cryptography and digital signal processing. In this paper, two Fourier Transforms are considered,…
Multidimensional Wavelets for Scalable Image Decomposition: Orbital Wavelets
H. M. de Oliveira, V. V. Vermehren, R. J. Cintra
Wavelets are closely related to the Schrödinger's wave functions and the interpretation of Born. Similarly to the appearance of atomic orbital, it is proposed to combine anti-symme…
An Overview of Self-Similar Traffic: Its Implications in the Network Design
Ernande F. Melo, H. M. de Oliveira
The knowledge about the true nature of the traffic in computer networking is a key requirement in the design of such networks. The phenomenon of self-similarity is a characteristic…
