A Vis-Spectrophotometer with a new topology of nanophotonic diffraction grating
Victor Vermehren Valenzuela, H. M. de Oliveira
This paper presents a new topology for photonic crystals to replace the monochromator, introducing them with a new alignment (the so-called extended Trinitron) to guide the chromat…
ND-Wavelets Derived from Anti-symmetric Systems of Isolated Particles using the Determinant of Slater
H. M. de Oliveira, V. V. Vermehren
Wavelets are known to be closely related to atomic orbital. A new approach of 2D, 3D and multidimensional wavelet system is proposed from a paralell with anti-symmetric systems of…
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…
Close Approximations for Daublets and their Spectra
V. V. Vermehren, J. E. Wesen, H. M. de Oliveira
This paper offers a new regard on compactly supported wavelets derived from FIR filters. Although being continuous wavelets, analytical formulation are lacking for such wavelets. C…
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…
