Residual-Corrected Equivalent-Circuit Model with Universal Differential Equations for Robust Battery Voltage Prediction under Operating-Condition Shift
Alexandre Barbosa de Lima, Roberta Vieira Raggi
Accurate terminal-voltage prediction underpins model-based battery management, yet low-order equivalent-circuit models (\ecm{}) lack expressiveness under transient conditions, wher…

Structure-Informed Estimation for Pilot-Limited MIMO Channels via Tensor Decomposition
Alexandre Barbosa de Lima
Accurate channel state information in wideband MIMO systems is constrained by pilot overhead, a challenge intensifying as bandwidths scale toward 6G. This paper proposes a structur…

Digital Twin--Driven Adaptive Wavelet Strategy for Efficient 6G Backbone Network Telemetry
Alexandre Barbosa de Lima, Xavier Hesselbach, José Roberto de Almeida Amazonas
Classical orthogonal wavelets guarantee perfect reconstruction but rely on fixed bases optimized for polynomial smoothness, achieving suboptimal compression on signals with fractal…
