Self-adjusting, or adaptive, systems have gathered much recent interest. We present a model for self-adjusting systems which treats the control parameters of the system as slowly varying, rather than constant. The dynamics of these parameters is governed by a low-pass filtered feedback from the dynamical variables of the system. We apply this model to the(More)
A functional analysis isolated peer attention as the primary maintaining variable for disruptive behavior displayed by a student with attention deficit hyperactivity disorder. Using a brief reversal design, noncontingent reinforcement was then shown to reduce disruptive behavior relative to the peer attention condition. Implications for assessing behavior(More)
Searching for information in large rather unstructured real-world data sets is a dicult task, because the user expects immediate responses as well as high-quality search results. Today, existing search engines, like Google, apply a keyword-based search, which is handled by indexed-based lookup and subsequent ranking algorithms. This kind of search is able(More)
Nanoplasmonic excitations as generated by few-cycle laser pulses on metal nanostructures undergo ultrafast dynamics with timescales as short as a few hundred attoseconds (1 as = 10(-18) s). So far, the spatiotemporal dynamics of optical fields localized on the nanoscale (nanoplasmonic field) have been hidden from direct access in the real space and time(More)
Konzepte aus der Domäne Tourismus beschränkt ist (siehe Abbildung 1). Die Wurzel der Ontologie ist das Konzept " Object ". Darunter wurden die vier Hauptkonzepte " TouristicObject " , " Person " , " Event " und " Media " definiert, von denen alle weiteren speziali-sierten Unterkonzepte abgeleitet werden. Das Konzept " TouristicObject " beschreibt Objekte,(More)
