Contrast of multi‐resolution analysis approach to transhumeral phantom motion decoding
CAAI Transactions on Intelligence Technology, 2021 In signal processing, multiresolution decomposition techniques allow for the separation of an acquired signal into sub levels, where the optimal level within the signal minimises redundancy, uncertainties, and contains the information required for the ...

Phantom maps and chromatic phantom maps [PDF]
American Journal of Mathematics, 2000 In the first part, we determine conditions on spectra X and Y under which either every map from X to Y is phantom, or no nonzero maps are. We also address the question of whether such all or nothing behavior is preserved when X is replaced with V Λ X for V finite. In the second part, we introduce chromatic phantom maps.

Study for pediatric protocol optimization in chest CT scans
Brazilian Journal of Radiation Sciences, 2019 Radiological exams are increasingly used in clinic for diagnostic analysis of different types of pathologies. These tests are associated with a dose that is received by the patient.
