In-Orbit Performance of the GRACE Follow-on Laser Ranging Interferometer
Get PDFThe Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km. Autonomous controls that lock the laser frequency to a cavity reference and establish the 5 degrees of freedom two-way laser link between remote spacecraft succeeded on the first attempt. Active beam pointing based on differential wave front sensing compensates spacecraft attitude fluctuations. The LRI has operated continuously without breaks in phase tracking for more than 50 days, and has shown biased range measurements similar to the primary ranging instrument based on microwaves, but with much less noise at a level of 1 nm/Hz at Fourier frequencies above 100 mHz. © 2019 authors.

A Lean Perspective of the Medication Delivery System at the Veterans Hospital - (VA Boston Healthcare System – West Roxbury Campus)
No full textNurse-patient interaction is vital to the quality of patient care at any hospital. To increase the amount of time nurses have to spend with their patients the West Roxbury VA Hospital installed a number of automated medication dispensing units. This medication delivery system provides a stock of medications that are immediately available to nurses. Our team worked to quantify the success of this system at reducing missing medications and to analyze the hospital's current medication delivery system as a whole
