New lower bounds for the constants in the real polynomial Hardy--Littlewood inequality
W. Cavalcante, D. Nunez-Alarcon, D. Pellegrino
In this short note we obtain new lower bounds for the constants of the real Hardy--Littlewood inequality for -linear forms on spaces when and for certain v…
Application of Enhanced-2D-CWT in Topographic Images for Mapping Landslide Risk Areas
V. V. Vermehren Valenzuela, R. D. Lins, H. M. de Oliveira
There has been lately a number of catastrophic events of landslides and mudslides in the mountainous region of Rio de Janeiro, Brazil. Those were caused by intense rain in localiti…
Magnetic and nonmagnetic phases in doped AB2 t-J Hubbard chains
R. R. Montenegro-Filho, M. D. Coutinho-Filho
We discuss the rich phase diagram of doped AB2 chains by using data from density matrix renormalization group and exact diagonalization techniques. The vs (hole dopin…
Inertial-Hall effect: the influence of rotation on the Hall conductivity
Julio E. Brandão, F. Moraes, M. M. Cunha +2
Inertial effects play an important role in classical mechanics but have been largely overlooked in quantum mechanics. Nevertheless, the analogy between inertial forces on mass part…
Wavelet Analysis as an Information Processing Technique
H. M. de Oliveira, D. F. de Souza
A new interpretation for the wavelet analysis is reported, which can is viewed as an information processing technique. It was recently proposed that every basic wavelet could be as…
A Row-parallel 88 2-D DCT Architecture Using Algebraic Integer Based Exact Computation
A. Madanayake, R. J. Cintra, D. Onen +4
An algebraic integer (AI) based time-multiplexed row-parallel architecture and two final-reconstruction step (FRS) algorithms are proposed for the implementation of bivariate AI-en…
