Follow the Data! A Strategy for Tracing Infrastructural Power

open access: yesMedia and Communication, 2023
Recalling the well-known strategy of “following the money” when investigating the underlying power structures and business models of legacy media, this article argues that studies of digital political economies can benefit instead from following the data.

The adaptive neural network sliding mode control for angle/force tracking of the dexterous hand

open access: yesAdvances in Mechanical Engineering, 2021
In order to achieve high precision control of the dexterous hand, an adaptive neural network sliding mode control algorithm based on the U-K (Udwadia-Kalaba) equation is proposed. Firstly, based on the U-K equation and considering the ideal and non-ideal

Mapping Distortion Correction in Null Testing of Sector-Shaped Off-Axis Aspheric Segments for Large Segmented Telescope

open access: yesPhotonics
Segmented primary mirror technology overcomes the manufacturing limitations of large-aperture monolithic mirrors by assembling the primary mirror from multiple off-axis aspheric sub-mirrors. However, null testing of such off-axis aspheric surfaces with a
