In this letter we consider a prototype model which is described as an autonomous continuous time delayed differential equation with just one variable. The chaos has been investigated with variable delay time and the synchronization phenomenon is examined both numerically and analytically using the Krasovskii-Lyapunov functions. We have applied adaptive coupling law for synchronization,where the...

Diese Arbeit behandelt die Klassifizierung des Himmels in Bergbildern. Zu Beginn wird ein Verfahren zur Abschätzung des Himmels in einem Bild vorgestellt. Im Anschluss folgt die Vorstellung eines auf FloodFill-basierenden Klassifikators. Abschließend werden die Ergebnisse verschiedener Klassifikatoren vorgestellt. Eine Klassifizierung des Himmels dient der Vorbereitung für eine spätere Segmenti...

Length and Structure: The ITSEA has two forms: a Parent Form and a Childcare Provider Form. Both forms can be selfadministered or administered as a structured interview. If both parents fill out self-administered questionnaires, it is important that they do so independently. The Parent Form consists of 4 domains with 17 subscales for a total of 166 items. The Childcare Provider Form is the same...

Innovative algorithms have been developed during the past decade for simulating Newtonian physics for macromolecules. A major goal is alleviation of the severe requirement that the integration timestep be small enough to resolve the fastest components of the motion and thus guarantee numerical stability. This timestep problem is challenging if strictly faster methods with the same all-atom reso...

Variational EM has become a popular technique in probabilistic NLP with hidden variables. Commonly, for computational tractability, we make strong independence assumptions, such as the meanfield assumption, in approximating posterior distributions over hidden variables. We show how a looser restriction on the approximate posterior, requiring it to be a mixture, can help inject prior knowledge t...

In a continuous-time setting, Fill (2012) proved, for a large class of probabilistic sources, that the number of symbol comparisons used by QuickSort, when centered by subtracting the mean and scaled by dividing by time, has a limiting distribution, but proved little about that limiting random variable Y —not even that it is nondegenerate. We establish the nondegeneracy of Y . The proof is perh...
