This UCB report summarizes preliminary design analysis for the 50 MW(t) intermediate heat exchanger (IHX) for the demonstration of hydrogen production with the Next Generation Nuclear Plant (NGNP). Sulfur-iodine (SI) hydrogen production efficiency is maximized when sulfuric acid decomposition is performed at a low pressure (~1 MPa) compared to the NGNP(More)
Activated sludge process has been widely adopted to remove pollutants in wastewater treatment plants (WWTPs). However, stable operation of activated sludge process is often compromised by the occurrence of filamentous bulking. The aim of this study is to build a proper model for timely diagnosis and prediction of filamentous sludge bulking in an activated(More)
1 This paper presents a practical direct adaptive fuzzy H ∞ tracking control (AFHC) approach for a class of uncertain nonlinear systems with unknown control gain functions and external disturbances. A modified output tracking error is defined to eliminate high gain at the control input and to improve transient performance. An ideal control law is developed(More)
