Proton double irradiation field-cycling nuclear magnetic resonance imaging: Testing new concepts and calibration methods
(Institute of Electrical and Electronics Engineers, 2020-11-11)
Double resonance experiments in field-cycling nuclear magnetic resonance (NMR) are powerful tools for the indirect detection of quadrupolar and electron resonances, dynamic nuclear polarization-induced signal amplification, ...
Obtaining accurate and calibrated coil models for transcranial magnetic stimulation using magnetic field measurements
(Springer Heidelberg, 2020-07)
Currently, simulations of the induced currents in the brain produced by transcranial magnetic stimulation (TMS) are used to elucidate the regions reached by stimuli. However, models commonly found in the literature are too ...
Workflow to spectral imagery calibration obtained in remotely piloted aircrafts (RPAs) by the empirical line methodFluxo de trabalho para a calibração de imagens espectrais obtidas em aeronaves remotamente pilotadas (ARPs) pelo método da linha empírica
(2019-01-01)
The usage of Remotely Piloted Aircrafts (RPAs) in environmental studies increased over the past years due to the possibility of performing low-cost aerial image acquisition. However, these studies often need to extract ...
Sistemas vinculados e o problema da fixação de calibre na ação
(Universidade Estadual Paulista (Unesp), 2019-12-13)
The present work deals with gauge symmetries in discrete systems and classical field theories. The text presents the method of counting degrees of freedom in Hamiltonian formalism in order to investigate the problem of ...
Análise comparativa dos resultados obtidos pelos métodos de calibração de campo tridimensional e bidimensional
(Universidade Federal do Paraná, 2015-06-01)
Automation resources have been used in Digital Photogrammetry in various applications. A complex and critical process in Photogrammetry, the camera calibration, can be performed automatically. Among the methods for camera ...
Modeling a spatially restricted distribution in the Neotropics: How the size of calibration area affects the performance of five presence-only methods
(Elsevier B.V., 2010-01-24)
We here examine species distribution models for a Neotropical anuran restricted to ombrophilous areas in the Brazilian Atlantic Forest hotspot. We extend the known occurrence for the treefrog Hypsiboas bischoffi (Anura: ...
