Development and Evaluation of Near‐Real Time TEC and Ancillary Products for SANSA Space Weather
Space Weather, Volume 20, Issue 5, May 2022., 2022 Abstract In this paper, the second version of SANSA's Total Electron Content (TEC) maps is presented with its associated methodology and assumptions. The method is based on Ma and Maruyama (2003, https://doi.org/10.5194/angeo-21-2083-2003) determination of receiver bias and hence TEC for individual receivers.

Real‐Time Monitoring of Ionosphere VTEC Using Multi‐GNSS Carrier‐Phase Observations and B‐Splines
Space Weather, Volume 19, Issue 10, October 2021., 2021 Abstract Monitoring the Vertical Total Electron Content (VTEC) of the ionosphere is important for applications ranging from navigation to detection of space weather events. Therefore, emerging efforts have been made by several analysis centers to estimate the VTEC using different approaches in real‐time.

Analysis of central place foraging behaviour of wolves using hidden Markov models
Ethology, Volume 127, Issue 2, Page 145-157, February 2021., 2021 Abstract The foraging movement behaviour of grey wolves (Canis lupus) is unique in summer, when the focus of breeding wolves is on taking care of new‐born offspring. In this study, we analysed the movement tracks of nine radio‐collared wolves during their pup‐rearing season. The wolves lived in the boreal zone in Finland.

Journal of Advanced Transportation, Volume 2021, Issue 1, 2021., 2021 Over‐/underspeeding is one of the leading causes of road accidents. Traditional systems of detecting and reporting speed‐limit violations are not suitable for smart cities. Even the sophisticated conventional systems that use cameras or RFIDs for automating speed‐limit violations have several drawbacks, including cost, complexity, reliability, and ...
