Development of a Unique Synthetic Data Set to Improve Sea-Level Research and Understanding

Muck Problems in Subway Shield Tunneling in Sandy Cobble Stratum

“…And surface settlement has been effectively controlled. Specific tunneling parameters are shown in Table3 and Table4 [5][6][7]. According to the geological and environmental conditions of Chengdu subway, the main role of the foam in EPB shield tunneling is to reduce the mechanical wear of shield machine.…”

How to improve estimates of real-time acceleration in the mean sea level signal

“…Although extensive research has been undertaken into sea level rise, there remains considerable conjecture and scientific debate about the temporal changes in mean sea level and the climatic and associated physical forcings responsible for them (Watson, 2015a). Of keen interest is whether there is a measurable acceleration in ocean water level records (e.g., Baart, Van Koningsveld, and Stive, 2011;Donoghue and Parkinson, 2011;Houston and Dean, 2011a;Houston and Dean, 2011b;Rahmstorf and Vermeer, 2011;Visser, Dangendorf, and Petersen, 2015;Watson, 2011], a feature central to projections based on the current knowledge of climate science (Stocker et al, 2013).…”

“…Improving knowledge of acceleration in mean sea level lies principally with improving the temporal resolution of the trend signal. This is no trivial task given that ocean water level records are a complex composite of numerous dynamic influences of largely oceanographic, atmospheric or gravitational origins operating on differing temporal and spatial scales, superimposed on a comparatively low amplitude signal of sea level rise driven by climate change influences (Watson, 2015a).…”

“…In total some 1450 separate analyses were applied to a complex synthetic data set (Watson, 2015a), resulting in 21 million individual time series analyses. Key findings from this analysis were that enhanced accuracy in resolving the temporal resolution of the trend were achieved through the use of longer, annual average data, coupled with the use of so called "data adaptive" analytics, in particular, SSA and multi-resolution wavelet decomposition.…”

Heating Control of Heated Twin Radiosonde Humidity Sensor Based on DMC

“…In addition, the dynamic characteristics of the system with pure lag or nonminimum phase are not affected by the direct application of the algorithm [17][18][19][20][21]. For resolving issues related to rain (cloud) drops soaked, freezing and other conditions that causing the humidity sensor to detect inaccurate moisture signals, a dual heating radiosonde humidity sensor was proposed in this paper based on the traditional heating control method, which effectively reduces the impact of humidity measurement accompanied with external environment [22][23][24][25][26][27][28][29].…”
