The performance of systems that exhibit repetitive disturbances can be significantly improved using repetitive control. If the repetitive disturbance is periodic with respect to time, perfect asymptotic disturbance rejection can be achieved by well known methods. However, many systems have a repetitive nature with respect to a variable other than time. For this type of systems, we propose a del...

The Cumulative Repetitive Learning Model (CRLM) explores a novel approach to learning that draws inspiration from the concept of cumulative addition in statistics. In this model, is viewed as sequential process gradually increasing knowledge through repetitive practice and review. Similar frequency statistics, where numbers are successively added create running total, CRLM emphasizes repeated a...

The effect of repetitive electrical field stimulation and the response of the guinea-pig and rat ileal longitudinal muscle to single pulse stimulations was examined. Single pulse field stimulation produced twitch contraction which was inhibited by repetitive field stimulation (10 Hz, 40V, 0.5 msec for 5 m). This inhibition was largely, though never completely, reversed by naloxone. Contrac...

Background: Tension and migraine headaches are the most prevalent types of headaches. Some emotional and psychological factors are associated with these headaches. Objectives: To elucidate the nature of individual differences in emotion regulation and repetitive negative thinking among patients with tension headaches and migraine and compare it with normal subjects. Materials & Methods: In th...
