Análise de metodologia para detecção de perda total de excitação em geradores síncronos sob condição de perda parcial de campo
(Universidade Federal do PampaUNIPAMPABrasilCampus Alegrete, 2017)
Unfolded partial least squares/residual bilinearizationcombined with the Successive Projections Algorithmfor interval selection:enhanced excitation-emission fluorescence data modeling in presence of inner filter effect
(Springer Heidelberg, 2015-05)
The use of the successive projections algorithm (SPA) for elimination of uninformative variables in interval selection, and unfold partial least squares regression (U-PLS) modeling of excitation-emission matrices (EEM),when ...
Energy loss of protons in Wolframiun using fully relativistic binding energies and wave functions, and mean excitation energies of W, Au, Pb and Bi
(American Physical Society, 2009-12)
We present a theoretical study on the energy loss of protons in wolframium by calculating target fully relativistic wave functions and binding energies. The HULLAC code is employed to obtain numerical solutions of the Dirac ...
Avaliação do desempenho dos métodos de proteção contra a perda de excitação em geradores síncronos: uma contribuição para a melhoria da técnica baseada em combinações de sinais
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2019-07-19)
This work aims to evaluate the behavior of synchronous generators against total (TLOE)
and partial (PLOE) loss of excitation, to demonstrate the behavior of the main electrical variables
involved, to analyze the performance, ...
Four-way kinetic-excitation-emission fluorescence data processed by multi-way algorithms. Determination of carbaryl and 1-naphthol in water samples in the presence of fluorescent interferents
(Elsevier Science, 2010-09)
Four-way data were obtained by recording the kinetic evolution of excitation-emission fluorescence matrices for samples containing the analytes carbaryl and 1-naphthol, two widely employed pesticides, in the concentration ...
Sensitivity of photoelectron energy loss spectroscopy to surface reconstruction of microcrystalline diamond films
(Applied Surface Science, 2013)
In X-ray Photoelectron Spectroscopy (XPS), binding energies and intensities of core level peaks are
commonly used for chemical analysis of solid surfaces, after subtraction of a background signal. This
background due to ...
Proteção contra perda de excitação em geradores síncronos: uma nova proposta utilizando o método do cálculo contínuo da impedância aparente
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-10-16)
This work presents a new Loss-of-Excitation in synchronous generators protection scheme based on the Continuous Apparent Impedance Calculation. This methodology aiming to improve security and dependability to the ANSI 40 ...
Simultaneous determination of pesticides in fruits by using second-order fluorescence data resolved by unfolded partial least-squares coupled to residual bilinearization
(Hindawi, 2018)
Abstract: In the present work, a chemometric-assisted spectrofluorimetric method has been developed for the simultaneous determination
of natural fluorescent pesticides, carbaryl, carbendazim, and thiabendazole, in orange ...
Calpain inhibition rescues troponin T3 fragmentation, increases Cav1.1, and enhances skeletal muscle force in aging sedentary mice
(Wiley Blackwell Publishing, Inc, 2016-06)
Loss of strength in human and animal models of aging can be partially attributed to a well-recognized decrease in muscle mass; however, starting at middle-age, the normalized force (force/muscle cross-sectional area) in ...
