Subsurface modeling from seismic and borehole data is important for reservoir prediction, geophysical exploration and production. A reasonable model should honor borehole rock properties and conform to seismic structural and stratigraphic features. Such a subsurface model can be di cult to create in cases complicated by faults and unconformities. Automatic and semi-automatic methods have been p...

This paper presents the formulation of a time-dependent seismic fragility format for bridges, as well as new insights into the potential effects of aging and deterioration on seismic vulnerability traditionally neglected in fragility modeling, including joint impacts of multiple component deterioration not investigated to date. The study evaluates the impact of lifetime exposure to chlorides fr...

based on the convolutional model, a seismic trace is the convolution of seismic source wavelet and reflection coefficient series of the earth. seismic source wavelet estimation is one of the most important stages in processing and interpretation of seismic data. accurate estimation of wavelet increases the efficiency of the deconvolution and temporal resolution of seismic data. on the other han...

Additionally, there is an increasing need to maintain easy access to historical information for business or regulatory requirements. For example, a company may need to protect its interests by retrieving historical financial transactions to satisfy customer inquiries and resolve claims. In other cases, corporate policy or government regulations dictate that data must remain accessible for years...

1 Monsanto Company (Monsanto) has petitioned APHIS for a determination that MON 87705 soybean is unlikely to pose a plant pest risk (Rogan, 2009) and, therefore, should no longer be a regulated article under APHIS’ 7 Code of Federal Regulations (CFR) part 340. APHIS administers 7 CFR part 340 under the authority of the plant pest provisions of the Plant Protection Act of 2000 . This plant pest ...

This Comment illustrates how government regulation, criminal justice, private legal actions, and market forces contribute to the security of online transactions. Further, it argues that government regulation aimed at the prevention of cybercrime should be the primary focus of the efforts to improve online security. Ultimately, the Comment argues that as more businesses more online, securing onl...

The savings and loan debacle of the 1980s was a costly but important learning event for depository regulation in the United States. The origins of the debacle lay in restrictive government regulation that eventually led to financial difficulties for savings and loan institutions in the late 1970s and early 1980s. The Congress and at least three presidential administrations delayed for far too l...

This discussion is divided into two parts. The first, which addresses takings of private water rights, makes the following points: government regulation of private property for a public purpose, such as protection of species, raises important constitutional questions concerning whether a compensable “taking” of private property has resulted. This section discusses the property and liberty inter...

Private enforcement, or litigation, has played a historic role in protecting public health in the United States. Litigation is often employed as a means to protect public health when government regulation is absent or ineffectual. Litigation has been successfully employed to control both asbestos and tobacco and is poised for success in combating the obesity epidemic. Litigation is effective be...

Nowadays, the stress analysis mostly aimed at general buried pipelines. And few of the gas pipelines in tunnel (especially under the seismic action) were analyzed. Therefore, it is necessary to analyze the stress distribution of gas pipeline under seismic action in tunnel. In this paper, CEASAR II software was used to establish the stress model of China-Myanmar XX tunnel pipeline under seismic ...
