Analysis of Electron Mobility in Inversion-Mode Al2O3/InxGa1-xAs MOSFETs [PDF]

, 2011
The electron mobility in Al2O3/InxGa1-xAs (x = 0.53, 0.65, or 0.75) metal-oxide-semiconductor field-effect transistors was analyzed for scattering by oxide charge, as well as interface charge and roughness, and compared with measured transfer ...

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

Deep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

GEOLOGY OF PASSION: G.H.’S RETURN TO THE CAVE

Revista Brasileira de Literatura Comparada, 2023
The Passion according to G.H. is one of the texts most commented on by specialized critics. Since it is a classic text, that is, a book that can be read by each new generation from new entries, the present work attempts a reading of Clarice Lispector’s ...

Dynamic prediction of coal and gas outburst risk based on quantitative analysis of stress–energy evolution and adaptive correction

Deep Underground Science and Engineering, EarlyView.
This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.

Gravity inversion of deep-crust and mantle interfaces in the Three Gorges area

Geodesy and Geodynamics, 2012
To better understand the heterogeneity of deep-crust and mantle interfaces in the region of the Three Gorges, China, we used the Parker-Oldenburg iterative inversion method to invert existing Bouguer gravity data from the Three Gorges area (1 : 500000 ...

Characteristics Analysis and Stage Division of Class Ⅰ Gas Hydrate Deposit Developed by Vertical Well and Depressurization Based on Numerical Analysis

Energy Science &Engineering, EarlyView.
The production process can be divided into two stages according to the relationship between the gas production rate and the decomposition gas rate. The ratio of cumulative decomposition gas to cumulative gas production can be used to evaluate the contribution of the gas hydrate layer.

Numerical Simulation Study on Optimization of Horizontal Sublevel Top‐Coal Caving Mining Technique for Steeply Inclined Extra‐Thick Coal Seam

Energy Science &Engineering, EarlyView.
As the sublevel height increases, the top‐coal recovery amount gradually increases, but both the top‐coal recovery rate and the thickened top‐coal recovery rate show a downward trend, and the decline in the top‐coal recovery rate is gradually increasing. The comparison indicates that the optimal sublevel height is 20 m.

Positive tectonic inversion of the Western Sicily margin: Geodynamic implications for the central sector of the Africa-Eurasia plate boundary

BSGF - Earth Sciences Bulletin
The offshore western Sicily region is located at the active Africa-Eurasia plate boundary, between the southern Tyrrhenian backarc basin and the African continental margin, where tectonic processes make this sector prone to strong earthquakes and ...
