Logarithmic conformal field theories with continuous weights [PDF]

open access: yes, 1997
We study the logarithmic conformal field theories in which conformal weights are continuous subset of real numbers. A general relation between the correlators consisting of logarithmic fields and those consisting of ordinary conformal fields is ...

Gas geological dynamic analysis and gas emission real-time pre-warning system

open access: yesGong-kuang zidonghua, 2015
In order to prevent coal and gas outburst accidents and improve mine security capacity, gas geological dynamic analysis and gas emission real-time pre-warning system was built in Xinyuan Company. Gas geology spatial database was built based on statistics

Numerical Simulation of the Cleaning Performance of a Venturi Scrubber

open access: yesEnergies, 2022
Industrial applications need to use different systems for the problem of gas cleaning. A lot of processes have been developed, such as the use of a venturi for gas cleaning and pollution reduction.

Power calculations for isentropic compressions of cryogenic nitrogen [PDF]

open access: yes
A theoretical analysis has been made of the power required for isentropic compressions of cryogenic nitrogen in order to determine the extent that the drive power for cryogenic tunnels might be affected by real gas effects.

The Response of US Macroeconomic Aggregates to Price Shocks in Crude Oil vs. Natural Gas

open access: yesEnergies, 2020
Price fluctuations in crude oil and natural gas, as important sources of energy, have a remarkable influence on our economies and daily lives. Therefore, it is extremely important to react appropriately and to formulate appropriate policies or strategies

Quotients and invariants of AS-sets equipped with a finite group action

open access: yes, 2019
Using the geometric quotient of a real algebraic set by the action of a finite group G, we construct invariants of GAS sets with respect to equivariant homeomorphisms with AS-graph, including additive invariants with values in ...

Enhanced Gas Recovery with Carbon Dioxide Sequestration in a Water-drive Gas Condensate Reservoir: a Case Study in a Real Gas Field [PDF]

open access: yesJournal of Petroleum Science and Technology, 2017
Gas reservoirs usually have high recovery due to high mobility and low residual gas saturation, although some of them producing under water-drive mechanism have low recovery efficiency.

Building the red sequence through gas-rich major mergers [PDF]

open access: yes, 2009
Understanding the details of how the red sequence is built is a key question in galaxy evolution. What are the relative roles of gas-rich vs. dry mergers, major vs. minor mergers or galaxy mergers vs. gas accretion? In Wild et al.

On weak shock diffraction in real gases [PDF]

open access: yes, 2014
Asymptotic solutions are obtained for the two-dimensional Euler system for real gases with appropriate boundary conditions which describe the diffraction of a weak shock at a right-angled wedge; the real gas effects are characterized by a van der Waals ...

Swept-wavelength mid-infrared fiber laser for real-time ammonia gas sensing

open access: yes, 2019
The mid-infrared (mid-IR) spectral region holds great promise for new laser-based sensing technologies, based on measuring strong mid-IR molecular absorption features.
