The geometric thinking in Mathematics degree: an analysis in the light of Duval and Van-Hiele
Educação Matemática Debate, 2020 In this research, we analyze the geometric thinking of undergraduate mathematics students from a university in Pernambuco. We are based on Duval's Theory of Semiotic Representation Records (1995), which presents a theoretical model on cognitive ...

Journal of Computer Assisted Learning, Volume 42, Issue 3, June 2026.ABSTRACT Background Pre‐service mathematics teachers frequently struggle with understanding the definitions and hierarchical classifications of quadrilaterals, often misidentifying inclusive relationships. These misconceptions hinder their ability to teach geometry effectively and reflect gaps in both content knowledge and pedagogical readiness.

Operational Near Real Time Global Riverine Sediment Flux Estimates From Space
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We present global estimates of riverine sediment flux derived from an open‐source suite of algorithms using the Harmonized Landsat Sentinel (HLS) and discharge products. We estimated Sediment Concentration (suspended sediment concentration [SSC]) via neural networks, trained and tested on matchups of in situ and HLS data, obtaining a median ...

Inside the ice shelf: using augmented reality to visualise 3D lidar and radar data of Antarctica
The Photogrammetric Record, Volume 34, Issue 168, Page 346-364, December 2019., 2019 From 2015 to 2017, the ROSETTA‐Ice project comprehensively mapped Antarctica's Ross Ice Shelf. The campaign imaged the ice‐shelf surface with lidar and its internal structure with ice‐penetrating radar. The first augmented reality (AR) visualisation of the Antarctic Ice Sheet, using the Microsoft HoloLens, is presented.

, 2022 Teorija Van Hiele pokušava dati odgovor na pitanje razine razumijevanja geometrije kao grane matematike, a sastoji se od pet razina koje opisuju razmišljanje ispitanika i sukladno tom ih smješta na jednu od tih pet razina.

Brain and Behavior, Volume 7, Issue 7, July 2017., 2017 In this work, we present our results of using machine learning to predict temporal behavior changes in Alzheimers Disease using entire topological feature maps of the hippocampus surface (2100 feature points). Our paper demonstrates that it is possible to use an entire topological map instead of just imaging derived volumetric measurements for ...
