This paper, submitted for the Workshop/Theme session on Virtual & Augmented Reality: Technology, Design & Human Factors, organized by ISPRS Working Group IV/9, explores the research field opened by experiments in virtual environments from multidisciplinary approach. At the recently established Cognitive Cartography Lab, Eötvös University, Budapest we designed an experiment to study and better understand the role of visuospatial displays in spatial cognition, in particular the cognitive conditions of navigation in an imaginary city with a map. Below we present some preliminary results based on our experiments recording the spatial behaviour of 62 subjects, including their verbal reactions and eye tracking data collected during the sessions. We measured the wayfinding behaviour of participants after an active or passive learning phase. The analysis of the accumulated data suggested no significant differences in the efficiency of spatial problem solving between the groups of subjects. For further investigation we found that – although salient visual cues grasped the attention of the participants – they could not benefit from this knowledge of landmarks in the actual navigational tasks. Despite the lack of group differences, the low number of getting lost in such complex, large-scale virtual environment suggests that participants could solve the navigational tasks rather efficiently, most probably due to using different cognitive strategies. The project was part of an educational development plan and was supported by the Student Talent Grant of Eötvös University. It was designed by a multidisciplinary research group including university students and offered them the opportunity to collaborate, cross disciplinary borders and develop their profile when contributing to front-line scientific research.

In this paper we present the application of various neutron-based methods carried out at the Budapest Neutron Centre. Non-destructive and non-invasive neutron radiography (NR), prompt gamma activation analysis (PGAA) and time-of-flight neutron diffraction (TOF-ND) analysis were applied to reveal more information on raw material and production techniques of bronze artefacts that can be dated to the Central European Bronze Age (2000–1200 BC).

The moisture content of 25 different paprika powders was determined by an electronic moisture analyzer at 40, 50, 60, 70, 80, 90, 100 and 105°C by near infrared spectroscopy, using both peak area and peak height for the water; and by the traditional drying method, using an electric oven at 100°C for 1, 2 and 3 h. The data matrix was evaluated by principal component analysis. It was established that the moisture content of paprika powders can be equally determined by each method. The use of the NIR method has been proposed because it is both rapid and accurate, and the presence of other volatile compounds does not influence the reliability of the determination of the moisture content.
