Adaptive stabilization with exponential decay [PDF]
Systems & Control Letters, 1990 Abstract Adaptive high gain stabilizers for classes of linear time-invariant state space systems are presented. The classes cover multi-input—multi-output systems where the state dimension is not known. Only standard assumptions such as minimum phase and known respectively unknown sign are required.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
