positioning underground reservoir by underground dams by using geoelectric method

Metagenome of the Siberian Underground Water Reservoir

We report on the metagenome of a deep subsurface aquifer in the Tomsk region of Russia, sampled via an oil exploration borehole drilled to a depth of 2.8 km. Methanogenic archaea were present in the water along with members of various bacterial phyla, including Firmicutes, Chloroflexi, Bacteroidetes, Ignavibacteriae, and uncultured candidate divisions.

Percolation Approach in Underground Reservoir Modeling

Assessing the Accuracy of Underground Positioning Using Pseudolites

Dr. William R Michalson is an Associate Professor in the Electrical and Computer Engineering Department at Worcester Polytechnic Institute, where he also directs the Satellite Navigation Laboratory. The majority of his research focuses on the development, test, and evaluation of GPS integrity monitoring algorithms, with an emphasis on integrity monitoring for sole-means of navigation and precis...

Framing Dependencies Introduced by Underground Commoditization

Internet crime has become increasingly dependent on the underground economy: a loose federation of specialists selling capabilities, services, and resources explicitly tailored to the abuse ecosystem. Through these emerging markets, modern criminal entrepreneurs piece together dozens of à la carte components into entirely new criminal endeavors. From an abuse fighting perspective, criminal reli...

Vibration Generated by Underground Railway Trains

The control of vibration generated by railways in tunnels is complicated by the dynamic interaction between tunnel and track. Conventional methods (floating slab track, ballast mats, under-sleeper pads) do not perform as well as might be expected and it is the purpose of this paper to explore the sources of error. The major factors which must be taken into account pertain to the three-dimension...

Connectivity Based Positioning System for Underground Vehicular Ad Hoc Networks

Underground vehicular ad-hoc networks are indorsing wireless networks because they can realize many goals such as improving the driving safety and monitoring the emergency alerts in underground environments (i.e., road tunnels). It is necessary for vehicular nodes to recognize their positions to achieve these goals. However, Global Positioning System (GPS) devices cannot operate in underground ...
