Dieser Leitfaden beschreibt Ansatzpunkte zur Implementierung von Assistenzsystemen für das Reichweitenmanagement von Elektrobussen im öffentlichen Personennahverkehr (ÖPNV) anhand eines Demonstratorsystems. Diese Systeme können den Betrieb von Elektrobussen ökologisch und ökonomisch optimieren und das Fahrpersonal unterstützen. Die Autoren untersuc...
Range plays a crucial role in the adoption and acceptance of electric mobility. Contrary to private car use, battery-electric buses (BEBs) in short-distance public transport ideally tend to exploit their available range on a daily basis to achieve optimal resource efficiency. Designing interfaces that provide accurate mental models of range dynamic...
Locomotion can be considered to represent a core need in human life and is—in its most natural form—achieved by using available muscular human energy to obtain relocation in space over time. In order to amplify the human capabilities of locomotion (e.g. expand the mobility space and pace) humans have developed mobility tools (i.e. vehicles) that au...

Energy-related behavior in resource dependent systems (e.g. electric vehicles, houses, ships) is an important factor for the actual energy efficiency such systems can achieve. Energy feedback human-machine-interfaces (HMIs) can support the awareness of energy dynamics in order to comprehend the situation and the influences on energy consumption and...
Die Nutzung eines elektrischen CarSharing-Fahrzeugs für Dienstreisen und sonstige Dienstfahrten kann finanzielle und ökologische Vorteile mit sich bringen. Dennoch gibt es Beispiele solcher Angebote, die in der Nutzungsintensität im Alltagsbetrieb weit unter dem möglichen Nutzungspotenzial bleiben. Über eine Online-Umfrage wurden 95 Mitarbeiter*inn...
Eco-driving plays a crucial role in the optimal use of electric buses in local public transport. Human-machine interfaces (HMIs) can support eco-driving but have to meet specific user requirements. We developed an indicator-based eco-driving interface prototype and then conducted an interview study with electric bus drivers (N = 10) to examine thei...

The purpose of this meta-analysis is to examine the nature and magnitude of the relation between
complex problem-solving skills (CPS) and intelligence, a topic that has been widely discussed
and that has instigated a vast array of partially contradicting findings in the past. Theoretically,
researchers have hypothesized the two constructs to be eve...
Questions
Question (1)
I would like to calculate the required sample size for a main study based on the results from my pilot study in a psychological experiment.
The hypotheses indicate a repeated measures multiple mean comparison, hence, a repeated measures ANOVA (one-way). In the pilot study, the normality assumption is violated, therefore, I used a Friedman test instead.
My question: How can I now calculate the required sample size for my main study? I already found the rule of thumb to add 15% of the calculated sample size for the corresponding parametric analysis. Yet, because the normality assumption is violated, I cannot trust this parametric analysis. I am therefore looking for an equation to calculate the required sample size with the output of the Friedman test.
Thanks in advance for your help

Psychological aspects like range stress are a key challenge for the optimal use of electric buses in local public transport. Goal of the project NuR.E is to support the driver-range interaction (assessment and extension) and to reduce uncertainty by providing prepared range assessment information and action-oriented range extension feedback through a user-centered interface system.
