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...

Our submission guesses at entailment based on word similarity between the hypotheses and the text. We attempt three kinds of comparisions: original words (with normalized dates and numbers) synonyms, and antonyms. Each of the three comparisions contributes a different weight to the entailment decision. Our results are insignificantly better than chance for the two-way comparison. However, for t...
