In the so called "one way" electric carsharing system, users can take a car at a station, use and leave it at another station. This process usually leads to a situation where some stations are full while others are empty. The system is especially compelling because vehicles are electrical and a minimal charging time is required. Therefore, a balanced system requires the optimal distribution of ...

Abstract Carsharing contributes to sustainable urban mobility by reducing private car ownership and use. Thus, policy-makers planners need know how cities can foster carsharing the related benefits. Decentralized hubs are an emerging approach supporting carsharing. These provide designated parking spots in public street spaces of residential neighborhoods. The objective is embed services into i...

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 ...
