TBSIM: A computer program for conditional simulation of three-dimensional Gaussian random fields via the turning bands method
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-12)
The simulation of spatially correlated Gaussian random fields is widespread in geologic, hydrologic and environmental applications for characterizing the uncertainty about the unsampled values of regionalized attributes. ...
Ultraviolet absorption bands and electronic charge transfers of salicylideneanilines in singlet excited states
(MARCEL DEKKER INC, 2001-01-12)
Salicylideneaniline presents an electronic absorption band spectrum of complex patterns between 200 and 450 nm. However, we have successfully developed the electronic transition assignments of this molecular compound and ...
Origin of chirality in charge transfer bands of Cu(II) acidates
(Pergamon Press, 1981)
Complexes of Cu(II) with L-aminoacids have positive charge transfer bands in their CD spectra at ca.230 nm and negative at ca. 270 nm. Examination of complexes with L-1,2-diamino propane shows that the positive band is ...
Low-Cost Ka-Band Cloud Radar System for Distributed Measurements within the Atmospheric Boundary Layer
(MDPI, 2020)
Radars are used to retrieve physical parameters related to clouds and fog. With these measurements, models can be developed for several application fields such as climate, agriculture, aviation, energy, and astronomy. In ...
Observation of localized ground and excited orbitals in graphene photonic ribbons
(IOP Publishing Ltd, 2018)
We report on the experimental realization of a quasi-one-dimensional photonic graphene ribbon supporting four flat-bands (FBs). We study the dynamics of fundamental and dipolar modes, which are analogous to the s and p ...
Line defect Ce3+ induced Ag/CeO2/ZnO nanostructure for visible-light photocatalytic activity
(Elsevier Science SA, 2018)
This article reports, synthesis and characterization of the ternary Ag/CeO2/ZnO nanostructure which was tested for visible light photocatalytic degradation of industrial textile effluent. The HR-TEM and XPS results confirms ...
First principle study of V-implantation in highly-doped silicon materials
(Elsevier, 2017)
Density Functional Theory (DFT) has been used to study structural and electronic properties of new compounds based on V-implanted Si and their potential as infrared photodetectors. Effects derived from the implantation of ...
Crystal structure, optical and magnetic properties of perovskite Gd(Mn0.7Ni0.3)O3 ceramic nanoparticles: An experimental and first-principles studies
(Elsevier Ltd, 2019)
The perovskite Gd(Mn0.7Ni0.3)O3 ceramic nanoparticles were synthesized by a facile sol-gel technique. The structure, electronic structure, surface morphology, optical and magnetic properties of GdMn0.7Ni0.3O3 nanoparticles ...
Characterization of sodium alginate and its block fractions by surface-enhanced Raman spectroscopy
(JOHN WILEY & SONS LTD, 2009-10-23)
The surface-enhanced Raman scattering (SERS) of sodium alginates and their hetero- and homopolymeric fractions obtained
from four seaweeds of the Chilean coast was studied. Alginic acid is a copolymer of β-D-mannuronic ...
On a continuous spectral algorithm for simulating non stationary Gaussian random fields
(Springer, 2018)
This paper presents an algorithm for simulating
Gaussian random fields with zero mean and non-stationary
covariance functions. The simulated field is obtained as a
weighted sum of cosine waves with random frequencies
and ...
