Ocean Observations Required to Minimize Uncertainty in Global Tsunami Forecasts, Warnings, and Emergency Response

open access: yesFrontiers in Marine Science, 2019
It is possible that no catastrophe has mobilized the global ocean science and coastal emergency management communities more than the 2004 Indian Ocean tsunami. Though the Pacific tsunami threat was recognized, and a warning system had been in place since

Pit size evaluation using millimeter wave nondestructive evaluation method [PDF]

open access: yes, 2005
Corrosion precursor pitting size evaluation is a critical issue in the maintenance of aircrafts. Estimation of pit overall dimensions and especially its depth directly affects the required effort and cost associated with repair and maintenance of ...

Near infrared reflectance spectroscopy compared with soil clay and organic matter content for estimating within-field variation in N uptake in cereals [PDF]

open access: yes, 2008
Adjusting fertiliser applications to within-field variations in nitrogen (N) mineralisation during the growing season can increase yields, improve crop quality, reduce costs and decrease nutrient losses to the environment. Predicting such variations at a

Near-field radiation across a spherical pore in mesoporous silica

open access: yes工程科学学报, 2015
A mesoporous silica substrate consists of uniformly distributed and unconnected spherical pores. Since the pore diameter is less than the characteristic wavelength of thermal radiation,near-field radiative heat transfer cannot be ignored.

Implications of groundwater level changes before near field earthquakes and its influencing factors - several earthquakes in the vicinity of the Longmenshan-Anninghe fault as an example

open access: yesFrontiers in Earth Science
Characteristics of groundwater level changes may be correlated with subsequent earthquake events. However, the relationship and its determining factors remain unclear.
