SELF-TUNING FUZZY CONTROL OF ELECTRO-HYDRAULIC SERVO SYSTEM
Proceedings of the JFPS International Symposium on Fluid Power, 1996 This study deals with a self-tuning fuzzy controller (STFC) when it is applied to an electro-hydraulic servo system. The STFC has a hierarchic structure consisting of an algorithm being identical to a fuzzy controller at the lower loop, and a tuning algorithm accommodating the performance evaluation and parameter modification function at the upper loop.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration
Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 915-924, April 2026.Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.
