We need to predict the probability of unprecedented flooding of lands and coastlines due to unexpected storms,overflowing rivers,hurricanes,tidal surges and dam failures.This paper addresses new record floods that exceed all prior“historic”levels and are invariably due to extreme or severe weather and/or unexpected precipitation,defeating barriers and causing extensive power system outages.Given their inherently low occurrence,the probabilities of new(rare)record floods are treated as random outcomes and independent events using classical statistical mechanics and related hypergeometric sampling.This analysis straightforwardly replaces tuning or fitting to“normal”precipitation,regular tides and prior flood data and the traditional use of multi-parameter extreme value distributions(EVDs)used for weather-induced flood forecasting and estimating“return periods”.The approach is not reliant on geographic computer models,meteorological forecasting,published“flood zone”charts,or hydrological techniques and images.We illustrate the universal applicability of this Bayesian-style approach of solely addressing new records for a wide range of specific flooding case studies for rivers,major hurricanes,quasi-periodic coastal tides,and dam failures.The quantitative link is shown between extreme event extent and power outage duration,and the results impact disaster resilience,infrastructure vulnerability and emergency preparedness measures. 展开更多

随着高速客运需求的不断增加,在货物运输线路上增开高速旅客列车的可能性非常大。在既有货运线路上开行高速旅客列车只需增加有限的成本,不必新建轨道就可以提供高速客运服务。这属于所谓的“高速”客运铁路的范畴,亦称“新兴高速”... 随着高速客运需求的不断增加,在货物运输线路上增开高速旅客列车的可能性非常大。在既有货运线路上开行高速旅客列车只需增加有限的成本,不必新建轨道就可以提供高速客运服务。这属于所谓的“高速”客运铁路的范畴,亦称“新兴高速”铁路,包括目前美国联邦铁路局规定的5级和6级铁路。美同联邦铁路局规定的7级铁路不允许开行最高速度为125mph的超级货运列车,通常不适用于客货共线运输。 展开更多

In this special issue, we invited a few leading materials researchers to present topics in thin films, coatings, and nano structures. Readers will find most recent developments in topics, including recent advances in hard, tough, and low friction nanocomposite coatings; thin films for coating nanomaterials; electroless plating of silver thin films on porous Al2O3 substrate; CrN/Nano Cr interlayer coatings; nano-structured carbide derived carbon (CDC) films and their tribology; predicting interdiffusion in high-temperature coatings; gallium-catalyzed silica nanowire growth; and corrosion protection properties of organofunctional silanes. Authors are from both national laboratories and academia. 展开更多
