COVID-19 and its long-term effects on activity participation and travel behaviour: A multiperspective view

This paper discusses possible long-term effects of COVID-19 on activity-travel behaviour. Making use of theories and concepts from economics, psychology, sociology, and geography, this work argues that lasting effects can be expected, and specifically that peak demand among car and public transport users may be lower than if the pandemic...

COVID-19 passenger transport measures and their impacts

Governments all over the world have had to implement various policy measures in order to curb the spread of COVID-19, impacting many people's lives and livelihoods. Combinations of measures targeting the transportation sector and other aspects of social life have been implemented with varying degrees of success in different countries. This...

Culture, Corona, Crisis: Best Practices and the Future of Dutch Museums

The consequences of the coronavirus and the physical limitations it imposes on museums and their visitors force museums to rethink cultural identity and to approach the exhibition of material artworks differently. Only a limited number of people are allowed to visit the museum at one time, booking time slots is mandatory, making it difficult to...

Study of Corona Configurations under DC Conditions and Recommendations for an Identification Test Plan

Corona is one of the most common forms of partial discharge (PD) occurring in high voltage (HV) energy systems. The corona mechanism in air is not exclusive to the field of energy applications but has also been widely studied by physicists to theorize mechanisms of charge transfer during the different phases of gas discharge. The phases of the...

Physical interpretation of the floating electrode defect patterns under AC and DC stress conditions

Partial discharge is a prevalent phenomenon under high voltage (HV) where the discharge partially bridges the gap between two electrodes. At increasing voltage levels, physical dimensions and distances between the electrical parts become critical. Designing electrical components for such high voltages and planning of high voltage laboratories...

New clustering techniques based on current peak value, charge and energy calculations for separation of partial discharge sources

Clustering techniques are of main interest for separation of partial discharge (PD) sources. The separation is achieved if it is possible to extract from the PD pulses specific information related to the source. In this sense, this paper explores the capability of fundamental quantities derived from PD current pulses such as the peak amplitude...
