Experimental study and weighting analysis of factors influencing gas desorption

open access: yesFrontiers in Earth Science, 2023
Gas is one of the necessary contributing factors for coal and gas outburst accidents, and the gas desorbed in coal is the energy carrier in the outburst process.

Some remarks on the pore water pressure dissipation patterns from the one-dimensional consolidation test [PDF]

open access: yesArchives of Civil Engineering, 2022
The pattern of pore water pressure dissipation from the one-dimensional consolidation test significantly affects the calculated value of the coefficient of consolidation. This paper discusses the interpretation methodology for laboratory dissipation data

Eclipses in V444 Cygni: analysis of the continuum λ 4244 Å light-curve on a class of non-negative monotonically decreasing concaved/convex functions [PDF]

open access: yesSymposium - International Astronomical Union, 1999
A continuum λ 4244 Å light-curve of the eclipsing binary V444 Cyg (WN5+O6) is solved. The results generally agree with the previous ones obtained by Antokhin et al. (1997), with the exception that the conclusion on the slowness of the acceleration in the extended atmosphere of the WR component must be ‘softened’.

Decreasing and complete monotonicity of functions defined by derivatives of completely monotonic function involving trigamma function

open access: yesDemonstratio Mathematica
Abstract In this study, using convolution theorem of the Laplace transforms, a monotonicity rule for the ratio of two Laplace transforms, Bernstein’s theorem for completely monotonic functions, and other analytic techniques, the authors verify decreasing property of a ratio between three derivatives of a function involving trigamma ...

A New Odd Beta Prime-Burr X Distribution with Applications to Petroleum Rock Sample Data and COVID-19 Mortality Rate

open access: yesData, 2023
In this article, we pioneer a new Burr X distribution using the odd beta prime generalized (OBP-G) family of distributions called the OBP-Burr X (OBPBX) distribution.

Vehicle Optimal Velocity Curves for Minimum-Time Maneuver

open access: yesAdvances in Mechanical Engineering, 2014
A problem in vehicle minimum-time maneuver is the assumption that a vehicle passes through a given path in a minimal amount of time without deviating from the boundary of the given path.

Local Risk Proneness in Analytically Approximated Utility Functions under Monotonically Decreasing Preferences [PDF]

open access: yes, 2018
We discuss an analytical arctan form to approximate decreasing utilities based on several nodes of its graphics elicited in interval form. We demonstrate the process on two types of nodes originating from different subjective elicitation approaches. Our focus is also on the local risk attitude estimator, which in the case of decreasing preferences ...

Exploring Non-Gaussianity Reduction in Quantum Channels

open access: yesEntropy
The quantum relative entropy between a quantum state and its Gaussian equivalent is a quantifying function of the system’s non-Gaussianity, a useful resource in several applications, such as quantum communication and computation.
