We consider t he language L of the st rings over t he alphabet {a, I} of sha pe x lxl where Ixl is t he length of the st ring x . We show that L is recognized in real t ime by an iterat ive array but not by a one-way cellular auto maton , while the lan guage {O, 1}*· L is recognized in real t ime by a cellula r automato n but not by an iterat ive array.

Consider the one-way ANOVA problem of comparing the means m1; m2; . . . ; mc of c distributions F1…x† ˆ F…x ÿ m1†; . . . ; Fc…x† ˆ F…x ÿ mc†. Solutions are available based on (i) normal-theory procedures, (ii) linear rank statistics and (iii) M-estimators. The above model presupposes that F1; F2; . . . ; Fc have equal variances (ˆ homoscedasticity). However practising statisticans content that ...

This study examined how Twitter was used by all U.S. state education agencies (SEAs) for public engagement in education. Drawing on the ecological model of communication, this study analyzed the latest 71,913 tweets from 40 SEAs that had official Twitter accounts. The results of correlation analysis indicate no significant relationship between the SEAs’ presence on Twitter and the SEAs’ targete...

This study was the first-ever experiment to test how ideal expressions in hypothetical online dating profiles and exposure to romantic media are related to profile attractiveness, romantic beliefs, and endorsement of ideal partner characteristics. The sample contained 249 undergraduate students from a small, southwestern university. The study is a one-way experiment, with five manipulations and...

In this paper, four new algorithms for improvements of MD5 and SHA-Keyed/Unkeyed MD5 and Keyed/Unkeyed SHA are proposed. We change the mode of ®xed retrieval of the parameters to that of dynamic retrieval of the parameters by applying a mapping between the index phrase and the parameter table. As shown in the experimental result, with 1% degradation of performance, comparing to the original alg...

Does speaking a language without number words change the way speakers of that language perceive exact quantities? The Pirahã are an Amazonian tribe who have been previously studied for their limited numerical system [Gordon, P. (2004). Numerical cognition without words: Evidence from Amazonia. Science 306, 496-499]. We show that the Pirahã have no linguistic method whatsoever for expressing exa...

HADES ist ein im WiN­Labor an der Universität Erlangen entwickeltes System zur Ermittlung qualitätsrelevanter Daten wie IP­Paketlaufzeit und Paketverluste in Computernetzwerken. Gemessene und statistisch bewertete Paketlaufzeiten lassen Rückschlüsse zu, wie die Qualität von Netzwerkverbindungen einzuordnen ist und wo kritische Netzwerksituationen auftreten bzw. auftreten können. In dieser Arbei...
