Lithium-ion battery pack arrays for lifespan enhancement
(2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 12/21/2017)
Depending on the application, power and energy requirements may differ significantly and, most likely, a single lithium-ion cell will not suffice. Battery packs offer cell interconnections that allow to obtain several ...
Enhanced rate capability of lithium deficient spinel via controlling cooling rate
(Elsevier Science, 2020-02)
Lithium-deficient and Lithium-excess spinels LixMn1.6Ni0.4O4 (x = 1.05, 0.9) were synthesized by co-precipitation method assisted by ethylene glycol-oxalic acid. Control of cooling rates was performed in order to improve ...
Spectral Restoration Based Speech Enhancement for Robust Speaker Identification
Spectral restoration based speech enhancement algorithms are used to enhance quality of noise masked speech for robust speaker identification. In presence of background noise, the performance of speaker identification ...

Does curvature enhance forecasting?
(Banco Central do Brasil, 2008)
In this paper, we analyze the importance of curvature term structure movements on forecasts of interest rates. An extension of the exponential three-factor Diebold and Li (2006) model is proposed, where a fourth factor ...
