ABOUT THE COVER " A fter school, I would often go down on Chestnut Street to see the pictures in Earle's Galleries, " Henry Ossawa Tanner recalled about his early years (1). He was especially drawn to the marine subjects of T. Alexan-der Harrison (1853–1930). " After drinking my fi ll of these art wonders, I would hurry home and paint what I had seen, and what fun it was " (1). When at age 12 o...

This paper is concerned with H∞ filtering problem for T-S fuzzy systems with partly immeasurable premise variables. By using measurable premise variables of fuzzy models as the premise variables of fuzzy filters, a new fuzzy filter scheme is constructed. Further based on a class of line integral fuzzy Lyapunov functions, a convex condition for designing H∞ filters is proposed. In contrast to th...

This paper presents the design of a digitally-controlled speed electrical drive in the presence of arbitrary external immeasurable load disturbances. The extraction of a known class of external disturbances is achieved by using the novel DOB (Disturbance Observer), in which the discrete-time model of external disturbance is included implicitly. It is shown, analytically, by simulation, and expe...

In this paper, an adaptive fuzzy backstepping output feedback control approach is proposed for a class of strict-feedback stochastic nonlinear systems with time delays and immeasurable states. Fuzzy logic systems are firstly utilized to approximate the unknown nonlinear functions, and then a fuzzy state observer is designed to estimate the immeasurable states. By combining the fuzzy adaptive co...

This review has focused on important but less visible aspects of fibromyalgia (FM) with respect to the high impact of this disorder on patients and societies. FM is a common but challengeable illness. It is characterized by chronic widespread pain, which can be accompanied by other symptoms including fatigue, sleep disturbances, cognitive dysfunction, anxiety and depressive episodes. While our ...
