A Test Method for Dynamic Transmission Error of Transmission Gear of High Speed Accessories of Aeroengine by Lou Jianglei, Ma Zhi, Lei Duncai, He Ling

“…In this system， the real-time rotation angel of the driving gear and driven gear is respectively measured at the same time by magnetic grid sensor， through the high-speed data acquisition， storage devices of NI and the producer/consumer design pattern of LabVIEW for real-time acquisition and storage of the high-frequency data. Finally， the digital counting method is used to obtain the gear dynamic transmission error curve. …”

A Characterization of the Diffuse Galactic Emissions in the Anticenter of the Galaxy by L. Fauvet, J. F. Macías-Pérez, S. R. Hildebrandt, F.-X. Désert

“…Using the Archeops and WMAP data, we perform a study of the anticenter Galactic diffuse emissions—thermal dust, synchrotron, free-free, and anomalous emissions—at degree scales. The high-frequency data are used to infer the thermal dust electromagnetic spectrum and spatial distribution allowing us to precisely subtract this component at lower frequencies. …”
