A characterization of Volunteered Geographic Information [PDF]

open access: yes, 2010
This paper characterizes the Volunteered Geographic Information (VGI) phenomenon and explores comprehensively its relation with SDI. The SDI component view is used as common framework for describing the main characteristics of VGI and as framework for

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.

Geographically Weighted Cronbach's Alpha (GWalpha): An Exploratory Local Measure of Reliability for Scale Construction

open access: yesGeographical Analysis, EarlyView.
ABSTRACT Scales, as survey instruments, are crucial for investigating people's attitudes and behaviors in social science research. Cronbach's alpha is the most frequently used measure of internal consistency reliability for multi‐item survey scales. Affected by the spatial context of respondents' locations, the reliability of responses to a scale may ...

Expertise‐inspired artificial intelligence pipeline for clinically applicable reconstruction of tooth‐centric radial planes: Development and multicenter validation

open access: yesBMEMat, Volume 3, Issue 3, September 2025.
The expertise‐inspired AI pipeline demonstrates significant clinical utility for rapid and precise analysis of dento‐maxillofafcial CBCT and benefits for intelligent oral health management. Abstract Owing to the tooth‐centered nature of most oral diseases, the tooth‐centric radial plane of cone‐beam computed tomography (CBCT) depicts the anatomical and
