The compensational loop constituted by the gasflow style angular velocity gyroscope was proposed to improve signal of gasflow style tilt. The compensational loop could remove acceleration interfere from the signal of tilt. This gasflow type assembled inertial sensor not only measured static state angular, but also restrained the acceleration disturbance(More)
Understanding how the dynamics of vegetation growth respond to climate change at different temporal and spatial scales is critical to projecting future ecosystem dynamics and the adaptation of ecosystems to global change. In this study, we investigated vegetated growth dynamics (annual productivity, seasonality and the minimum amount of vegetated cover) in(More)
A tree-ring width chronology was developed using the tree-ring cores of Huangshan pine (Pinus taiwanensis Hayata) from the Dabie Mountains, central China. Descriptive statistics of the chronology indicated that Huangshan pine showed a common signal likely associated to climate. A correlation analysis was conducted between the chronology and climate(More)
This paper reported the structure rule and the signal processing technique of the sensor that utilizes the gas pendulum property of natural convection in the hermetic chamber to sense carrier obliquity. The sensor organ design, signal processing technique and software compensation effect of one dimension, two dimensions and omnidirectional tilt sensors were(More)
