Water disaster is one of the five natural disasters in coal mines, and it badly threats the lives safety of miners. As well known, the main reason of evoked flooding is water conducted fractured zone in the coal seam. Based on the Maxwell equation, we try to study the relationship between apparent resistivity and stratigraphic dip as well as strata direction. The numerical results show that the...

Used initially in exploration, the dipmeter tool helped to locate and identify the major features of geologic structures that serve as oil traps. With improved techniques in data acquisition and computation, the application of this tool has expanded until it has become the principle logging measurement for describing internal lithologic features as well as revealing the sedimentological process...

Organic field-effect transistors (OFETs) were fabricated by depositing a regioregular poly(3-hexylthiophene) (P3HT) active layer using a dip-coating method. The field-effect mobility in OFETs depends on chain orientation and crystallinity and is related to direction and withdrawal speed with respect to the source/drain orientation. In this paper, how to control the structural and transport prop...

Continuously recording Global Positioning System stations near the 28 March 2005 rupture of the Sunda megathrust [moment magnitude (Mw) 8.7] show that the earthquake triggered aseismic frictional afterslip on the subduction megathrust, with a major fraction of this slip in the up-dip direction from the main rupture. Eleven months after the main shock, afterslip continues at rates several times ...

Polycrystalline SrBi2Nb2O9-layered ferroelectric thin films were synthesized on PtyTiySiO2ySi substrate using the polymeric precursors solution. The dip-coated films were specular and crack-free and crystallized during firing at 700 ±C. Single-, double-, and triple-layered films were obtained by several dips in the deposition solution, and the influence of crystallization between each dip was s...

We present a stand-alone software platform, Borehole and Ice Feature Annotation Tool (BIFAT), for the examination, annotation and analysis of glacier borehole images. This tool aids in the lengthy and often subjective process of annotating layers and other features in optical and acoustic glacier borehole televiewer logs. Since these view 360◦ around the full circumference of an exploratory bor...

Map of geological cross section is the most intuitive expression strata in vertical direction. Realizing automatic filling lithologic patterns and reflecting changes stratum curvature are important contents map drawing. The traditional pattern method can not show change rock dip angle. To solve this problem, an algorithm drawing based on arc fitting proposed. By analyzing mathematical relations...
