Many natural phenomena, including geologic events and geophysical data, are fundamentally nonstationary exhibiting statistical variation that changes in space and time. Time-frequency characterization is useful for analyzing such data, seismic traces in particular. We present a novel time-frequency decomposition, which aims at depicting the nonstationary character of seismic data. The proposed ...

Animal reservoirs for infectious diseases pose ongoing risks to human populations. In this theory of zoonoses, the introduction event that starts an epidemic is assumed to be independent of all preceding events. However, introductions are often concentrated in communities that bridge the ecological interfaces between reservoirs and the general population. In this paper, we explore how the risks...

Throughout the 700-yearlong coal exploration period in Ruhr region, an abundance of geological, geophysical, seismic, and situ stress data was obtained from Carboniferous strata. In this study, we take advantage unique dataset to develop a static 3D geomechanical model predict spatially continuous distribution undisturbed state evaluate reactivation risk major fault zones. Compared point-wise i...

for marshall hodgson, the history of the islamic civilization is not an event, rather it is a chain of continuous events happening with a global harmony and historical continuity, enjoying a spirit among different cultures and nations and throughout historical periods. the continuity of historical events in the islamic world does not amount to the interconnection of all events in the islamic hi...

Introduction: Occupational nature, strenuous physical activity, shift work, spatial and geographical location, as well as support facilities and equipment, pose greater risks to individuals in the oil and gas industry, especially those engaged in offshore oil exploration and production activities. The purpose of this article is to explain the issue of health and well-being of oil and gas indust...
