IEEE Transactions on Instrumentation and Measurement, 2021 The accuracy of gravity disturbance horizontal components is an obstacle in strapdown airborne vector gravimetry at present. In the strapdown inertial navigation system (SINS) field, the rotation modulation technique has been put into practice to improve

Behaviour of semi-rigid composite connections for steel framed buildings [PDF]
, 2009 During propped construction the steel-concrete composite action resists dead as well as imposed loads. Conversely, the steel section alone resists the floor self-weight in unpropped beams.

Solar tracker with optical feedback and continuous rotation [PDF]
Atmospheric Measurement Techniques, 2020 Solar trackers are often used by spectrometers to measure atmospheric trace gas concentrations using direct sun spectroscopy. The ideal solar tracker should be sufficiently accurate, highly reliable, and with a longevity that exceeds the lifetime of the ...

Breaking continuous potato cropping with legumes improves soil microbial communities, enzyme activities and tuber yield. [PDF]
PLoS ONE, 2017 This study was conducted to explore the changes in soil microbial populations, enzyme activity, and tuber yield under the rotation sequences of Potato-Common vetch (P-C), Potato-Black medic (P-B) and Potato-Longdong alfalfa (P-L) in a semi-arid area of ...

Testing-Based Approach to Determining the Divergence Speed of Slung Loads
Aerospace, 2018 When a rotorcraft carries an external slung load, flight speed is often limited by the fear of divergent oscillations, rather than vehicle performance.

Analysis of potato-maize rotation on rhizosphere soil nutrient and enzyme activity for potato
浙江大学学报. 农业与生命科学版, 2016 As the fourth major food crop, potato growing area increased year by year, which was an important mainstay industry in some provinces of China. In recent years, continuous cropping became common in potato growing areas.
