Eftekhar, Z. (author), Pel, A.J. (author), van Lint, J.W.C. (author)Global System for Mobile Communications (GSM) data provides valuable insights into travel demand patterns by capturing people's consecutive locations. A major challenge, however, is how the polling interval (PI; the time between consecutive location updates) affects the accuracy in reconstructing the spatio-temporal travel patterns. Longer...journal article 2023

de Wilt, Wouter (author)Big data analytics (BDA) and supply chain resilience are both present and important topics, but research on the relation between the subjects is limited. This also holds for the translation of the subject for a specific industry. This research therefore addresses this relation and translates it to a comprehensive partial resilience assessment...master thesis 2022

Gadepalli, Ravi (author), Gumireddy, Sushmitha (author), Bhamidipati, Srirama (author), Cats, O. (author)Many cities have introduced metro rail systems over the past two decades, particularly in developing countries. However, there is lack of knowledge on the impacts of new lines on the service and ridership for the related urban bus lines, and in particular those directly affected by the opening of the new service(s). We undertake a...journal article 2022

Galanopoulos, Apostolos (author), Iosifidis, G. (author), Salonidis, Theodoros (author), Leith, Douglas J. (author)An increasing number of mobile applications rely on Machine Learning (ML) routines for analyzing data. Executing such tasks at the user devices saves the energy spent on transmitting and processing large data volumes at distant cloud-deployed servers. However, due to memory and computing limitations, the devices often cannot support the...journal article 2022
