(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)I review recent highlights of the SAAO High-speed Photo-POlarimeter (HIPPO) on the study of magnetic Cataclysmic Variables. Its high-speed capabilities are demonstrated with example observations made of the intermediate ... -
High-speed rail network and periodic timetable: a comparative analysis of operational concepts
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)This paper compares chosen European high-speed railway (HS) networks in terms of their offer of HS passenger service. The criteria chosen for comparison are network topology, degree of service periodicity and degree of ... -
High-speed rail – highway 2.0?
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)High-speed rail lines should make it possible to fully replace air transport over the medium distances of Europe (about 500 km). In the Czech Republic, they are beginning to design. Estimates suggest that in five years, ... -
