Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.Abstract We analyze five large‐scale tail disturbances in comet C/2022 E3 (ZTF)'s ion tail using images from astrophotographers, tracking specific features within the tail to determine their speeds. We employ a heliosphere model to estimate when the comet crossed the heliospheric current sheet (HCS).

The relational nature of citizen science
People and Nature, Volume 6, Issue 5, Page 2060-2076, October 2024.Abstract Most citizen science research inherently separates the observer (citizen science participant) from the observation (e.g. data point), placing artificial boundaries around what matters and how it comes to matter. We apply three elements of the philosophical framework of agential realism to reveal a more complex picture of how data arise within ...

ExposureNet: Mobile camera exposure parameters autonomous control for blur effect prevention
IET Image Processing, Volume 18, Issue 12, Page 3403-3414, 16 October 2024.The ExposureNet project addresses the issue of image blur caused by imbalanced camera exposure settings, by developing an autonomous system for controlling these settings. The system, trained comprehensively, predicts ideal exposure based on the semantic features of a scene, using only shutter speed and ISO as training signals.

Estimation of Reactive Torque Effect on Image Blur
Известия высших учебных заведений России: РадиоэлектроникаIntroduction. When the optical system of a spacecraft rotates, the motion of its internal components initiates the emergence of a reactive torque. This torque causes unintended angular displacement of the spacecraft body, leading to a deviation of the ...
