International Journal of Adaptive Control and Signal Processing, EarlyView.This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Surface Magnetic Flux Density Patterning in EDM of Permanent Magnets
Procedia CIRP, 2016 Abstract Traditional machining of permanent magnets is difficult because of magnetic forces and the brittleness of the materials. However, electrical discharge machining (EDM), a non-contact thermal machining method, has been successfully applied for the shape machining of magnetic materials. Magnetic materials are characterized by a Curie point, and

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
