A Comparison of Threshold-Free Measures for Assessing the Effectiveness of Educational Interventions (2024)
Journal Article
Einbeck, J., Coolen-Maturi, T., Uwimpuhwe, G., & Singh, A. (online). A Comparison of Threshold-Free Measures for Assessing the Effectiveness of Educational Interventions. The Journal of Experimental Education, https://doi.org/10.1080/00220973.2024.2405738

The effectiveness of educational interventions has traditionally been evaluated using effect size measures which focus on a single feature of the distribution of the outcomes under intervention and control conditions: a (standardized) mean difference...

Tip tilt and focus estimation based on LGS and downlink joint measurements for ground to GEO satellite optical communication link (2024)
Journal Article
Lognoné, P., Rekaya, G., Montmerle-Bonnefois, A., Paillier, L., & Conan, J.-M. (2024). Tip tilt and focus estimation based on LGS and downlink joint measurements for ground to GEO satellite optical communication link. Optics Express, 32(21), 37739-37757. https://doi.org/10.1364/oe.538333

Achieving high data rates in GEO Feeder optical uplinks faces challenges due to the fading nature of the channel induced by atmospheric turbulence. Adaptive optics pre-compensation using downlink measurements is a solution to mitigate the impact of t...
