3D Display of Spacecraft Dynamics Using Real Telemetry [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2002
3D display of spacecraft motion by using telemetry data received from satellite in real-time is described. Telemetry data are converted to the appropriate form for 3-D display by the real-time preprocessor.

Estimation of a General Along-Track Acceleration in the KOMPSAT-1 Orbit [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2002
General along-track acceleration was estimated in the KOMPSAT-1 orbit determination process. Several sets of the atmospheric drag and solar radiation pressure coefficients were also derived with the different spacecraft area.

Neural network-based colonoscopic diagnosis using on-line learning and differential evolution [PDF]

open access: yes, 2004
In this paper, on-line training of neural networks is investigated in the context of computer-assisted colonoscopic diagnosis. A memory-based adaptation of the learning rate for the on-line back-propagation (BP) is proposed and used to seed an on-line ...

Strong Coulomb effects in hole-doped Heisenberg chains

open access: yes, 2005
Substances such as the ``telephone number compound'' Sr14Cu24O41 are intrinsically hole-doped. The involved interplay of spin and charge dynamics is a challenge for theory.

Sequential drain amylase to guide drain removal following pancreatectomy [PDF]

open access: yes, 2018
BACKGROUND: Although used as criterion for early drain removal, postoperative day (POD) 1 drain fluid amylase (DFA) ≤ 5000 U/L has low negative predictive value for clinically relevant postoperative pancreatic fistula (CR-POPF).
