Data from the Gravity Recovery and Climate Experiment (GRACE) satellite mission can be used to monitor changes in terrestrial water storage (TWS). In this study, we exploit TWS observations a new temporal gravity field model, Tongji-Grace2018, which was developed using an optimized short-arc approach at Tongji University. We analyzed groundwater (GWS) each of nine major river basins Chinese mai...

In this extended abstract, we explain a demo of the leakage-resilient authentication and data (key) management system which can be regarded as a prominent solution for secure cloud storage.

Well blowout rates in oil fields undergoing thermally enhanced recovery (via steam injection) in California Oil and Gas District 4 from 1991 to 2005 were on the order of 1 per 1,000 well construction operations, 1 per 10,000 active wells per year, and 1 per 100,000 shutin/idle and plugged/abandoned wells per year. This allows some initial inferences about leakage of CO2 via wells, which is cons...

River basins are key components of water supply grids. River basin operators must handle a complex set of objectives including runoff storage, flood control, supply for consumptive use, hydroelectric power generation, silting management, and maintenance of river basin ecology. At present, operators rely on a combination of simulation and optimization tools to help them make operational decision...

Many enterprise environments have databases running on network-attached storage infrastructure (referred to as Storage Area Networks or SANs). Both the database and the SAN are complex subsystems that are managed by separate teams of administrators. As often as not, database administrators have limited understanding of SAN configuration and behavior, and limited visibility into the SAN’s run-ti...

Soil moisture influences and is influenced by water, climate, and ecosystem conditions, affecting associated ecosystem services in the landscape. This paper couples snow storage-melting dynamics with an analytical modeling approach to screening basin-scale, long-term soil moisture variability and change in a changing climate. This coupling enables assessment of both spatial differences and temp...

In recent years, accidents of urban large scale sewage treatment plant at home and abroad have took a big loss to countries and individuals. Based on field research and scientific analysis of one large sewage treatment plant this paper use the safety check list to evaluate its safety and get that the main risk factors which should be focused on are poisoning and suffocation, electrical injuries...
