In this paper, a filtered repetitive controller (FRC) is proposed for robot manipulator tracking. Error dynamics are obtained first, leaving an unknown periodic signal to be compensated. A new model to describe the periodic signal is proposed then. By this model, an FRC is designed to compensate for the unknown periodic signal. The resulting closed-loop error dynamics are analyzed with the help...

A fiber-reinforced composite (FRC) fixed prosthesis is an innovative alternative to a traditional metal restoration, as it is a conservative treatment method. This case report demonstrates a detailed procedure for restoring a missing anterior tooth with an FRC. A 44-year-old woman visited our department with an avulsed tooth that had fallen out on the previous day and was completely dry. This t...

Cat feeders serve as an important source of available food for free-roaming cats (FRCs) and can play a central role in providing data on FRC distribution, welfare, and health. Data on cat feeder personalities as well as a better understanding of their feeding practices offer relevance for decision making concerning FRC population control strategies. The current study surveyed 222 FRC feeders wh...

In this paper we investigated a fuzzy logic-based video rate control technique which aims to regulate the data rate of compressed video at a constant transmission rate without objectionable quality degradation. It is considered that conventional fuzzy rule-based control (FRC) does not eeectively control the two variables (video data rate and video quality) which are mutually contradictory. The ...

We present an experimental technique that permits mechanical-noise-free, cavity-enhanced frequency measurements of an atomic transition and its hyperfine structure. We employ the 532-nm frequency-doubled output from a Nd:YAG laser and an iodine vapor cell. The cell is placed in a folded ring cavity (FRC) with counterpropagating pump and probe beams. The FRC is locked with the Pound-Drever-Hall ...

In gambling situations, we found a paradoxical reinforcing effect of high-risk decision-making after repeated big monetary losses. The computerized version of the Iowa Gambling Task (Bechara et al., 2000), which contained six big loss cards in deck B', was conducted on normal healthy college students. The results indicated that the total number of selections from deck A' and deck B' decreased a...

This report describes DeckScape, an experimental World-Wide Web browser based on a deck metaphor. A deck consists of a collection of Web pages, and multiple decks can exist on the screen at once. As the user traverses links, new pages appear on top of the current deck. Retrievals are done using a background thread, so all visible pages in any deck are active at all times. Users can move and cop...

A non-invasive index of airway distensibility is required to track airway remodeling over time. The forced oscillation technique (FOT) provides such an index by measuring the change in respiratory system conductance at 5 Hz over the corresponding change in lung volume (ΔGrs5/ΔVL). To become useful clinically, this method has to be reproducible and easy to perform. The series of breathing maneuv...

1. THE OVERHAND SHUFFLE (~o The two most common methods of shuffling a deck of playing cards are the riffle shuffle and the overhand shuffle. The riffle shuffle is performed by splitting the deck into two halves and interlacing them. Aldous and Diaconis have shown in Ref. I that approximately 2 log N riffle shuffles suffices to randomize a deck (the meaning of this will be made more precise bel...
