Rarefied gas effects on the aerodynamics of high area-to-mass ratio spacecraft in orbit [PDF]
The aerodynamic situation of a satellite-on-a-chip operating in low Earth orbit bears some resemblance to a classical Crookes radiometer. The large area-to-mass ratio characteristic of a SpaceChip means that very small surface-dependent forces produce ...

ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Accuracy Assessment of SGP4 Orbit Information Conversion into Osculating Elements [PDF]
The SGP4 model is one of the analytical orbit models applied for the orbit prediction using TLE orbit information. For the orbit accuracy improvement, a model conversion was performed to apply a more precise model. Assuming that a TLE data set is the
