A data fusion-based framework to integrate multi-source VGI in an authoritative land use database

open access: yesInternational Journal of Digital Earth, 2021
Updating an authoritative Land Use and Land Cover (LULC) database requires many resources. Volunteered geographic information (VGI) involves citizens in the collection of data about their spatial environment. There is a growing interest in using existing

Numerical approach for retention characteristics of double floating-gate memories

open access: yes, 2010
We report on a numerical investigation in which memory characteristics of double floating-gate (DFG) structure were compared to those of the conventional single floating-gate structure, including an interference effect between two cells.

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

The Future of VGI

open access: yes, 2017
In this final chapter, we speculate on future developments in the field of Volunteered Geographic Information (VGI); we focus on how VGI will be a affected by future technological developments, but we also consider issues such as VGI quality, the relationship of VGI with science and citizens, and the impact of VGI in future cities and societies.
