Proceedings of the Third (2016) ACM Conference on Learning @ Scale, 2016
Staff from edX, MIT, and Harvard will present two instructor dashboards for edX MOOCs. Current workflows will be described, from parsing and displaying data to using dashboards for course revision. A major focus will be lessons learned in the first two years of deployment.

Proceedings of the 5th International Conference on Technological Ecosystems for Enhancing Multiculturality, 2017
In this article an interactive tool for supporting the generation of Predictive Models for edX MOOCs is presented. This tool is a modular and scalable application that, based on the data collected from a MOOC course, allows the simple application of a complete Data Science process, where Machine Learning algorithms are applied to generate predictive ...

The application of EDXS to the biological sciences
Journal of Microscopy, 1984SUMMARYThe distribution of chemical elements in soft tissues may be faithfully preserved by very rapid freezing. Most often the material is then cryosectioned and the sections frozen‐dried prior to analysis, but direct analysis in the hydrated state is an established alternative.For bulk specimens, the shape of the analysed volume is uncertain.

Deep learning STEM-EDX tomography of nanocrystals
Nature Machine Intelligence, 2021Energy-dispersive X-ray spectroscopy (EDX) is often performed simultaneously with high-angle annular dark-field scanning transmission electron microscopy (STEM) for nanoscale physico-chemical analysis. However, high-quality STEM-EDX tomographic imaging is still challenging due to fundamental limitations such as sample degradation with prolonged scan ...

Optimization of EDX performance in Tecnai TEMs
Micron, 2003The quality of X-ray spectra from FEGTEMs has been improved by three different means: the use of beryllium shields, improved collimation and improved specimen holder geometry. The improvements lead to a significant increase in peak-to-background ratios and a reduction in spurious peaks in the EDX spectra.

The EDX Spectrometer in Museumuse
International Institute for Conservation of Historic and Artistic Works, 1971The enthusiasm for X-ray Fluorescence Spectroscopy using energy dispersive detection (EDX) evinced over the past year or so by Frankel,1 Hanson2 and workers in Ottawa3'4will continue, and a deluge of analytical results can be safely prophesized in the near future.

EDX - Energiedispersive Röntgenspektroskopie
2017EDX ist neben WDX eine Methode der Elektronenstrahlmikroanalyse, welche die von einem Festkorper infolge eines Elektronenbeschusses emittierten charakteristischen Rontgenstrahlen nutzt, um die darin enthaltenen Elemente qualitativ und quantitativ zu bestimmen.

An outcome-based dashboard for moodle and Open edX
Proceedings of the Seventh International Learning Analytics & Knowledge Conference, 2017This poster presents a cross-platform learning analytics dashboard on Moodle and Open edX for monitoring outcome-based learning progress. The dashboard visualizes students' interactions with the platforms in near real-time, aiming to help teachers and students monitor students' learning progress.
