Abstract: This article investigates the librational motion control problem of the tethered space-tug (TST) system in the process of deorbiting space debris. By analyzing the dynamic equations of the ...

Umpires first began calling both balls and strikes way back in 1864, and baseballers have been arguing about those calls ever since. Strike-zone judgment has been the subject of some untold number of ...

Abstract: This article presents a wearable, low-cost, and high-accuracy electrogoniometry system designed for the dynamic measurement of range of motion (ROM). The system integrates two-axis ...
