The influence of the length of the calibration period and observation frequency on predictive uncertainty in time series modeling of groundwater dynamics

The influence of the length of the calibration period and observation frequency on the predictive uncertainty in time series modeling of groundwater dynamics is investigated. Studied series are from deltaic regions with predominantly shallow groundwater tables in a temperate maritime climate where heads vary due to precipitation and...

The use of questionnaires in colour research in real-life settings: In search of validity and methodological pitfalls

This research discusses the validity of applying questionnaires in colour research in real life settings.<br/>In the literature the conclusions concerning the influences of colours on human performance and well-being are often conflicting. This can be caused by the artificial setting of the test process. Applying questionnaires could also be a...
