Bayesian Mode Regression [PDF]

open access: yes, 2014
This article has been made available through the Brunel Open Access Publishing Fund.Like mean, quantile and variance, mode is also an important measure of central tendency of a distribution.

Review of Research Progresses and Application of Geothermal Disaster Prevention on Large-Buried Tunnels

open access: yes, 2022
Geothermal disaster caused by high geotemperature is a commonly encountered geological problem in tunnel engineering, especially in large-buried tunnels, which is directly related to the safety, technology, and economy of tunnel construction.

External cavity mode structure of a two-mode VCSEL subject to optical feedback [PDF]

open access: yes, 2007
We consider a multi-transverse-mode vertical-cavity surface-emitting laser (VCSEL) subject to optical feedback. The system is modeled by a partial differential equation for the spatial carrier population, which is coupled to delay differential equations ...

A self-adaption horizontal thermosyphon technology in uneven thermal control of roadway embankments in sub-arctic permafrost regions

open access: yes, 2022
Most roadways have differential solar absorption across the embankment in cold regions due to the slope-facing problem or the difference in slope surface conditions, which can cause uneven thermal distribution and result in longitudinal crack.

A new numerical method for evaluating the variation of casing inner diameter after strike‐slip fault sliding during multistage fracturing in shale gas wells

open access: yesEnergy Science &Engineering, Volume 7, Issue 5, Page 2046-2058, October 2019., 2019
In this study, the relationship between microseismic moment magnitude and sliding distance was established. A 3D numerical model, considering the mechanical anisotropy of shale and heat‐fluid‐solid coupling effect during multistage fracturing, was developed to quantify variation of casing inner diameter after fault sliding.

A Cause Analysis of the High‐Content Nitrogen and Low‐Content Hydrocarbon in Shale Gas: A Case Study of the Early Cambrian in Xiuwu Basin, Yangtze Region

open access: yesGeofluids, Volume 2019, Issue 1, 2019., 2019
There are successes and failures in the exploration of marine shale gas in South China. In some shale gas plays with great basis for hydrocarbon generation, a phenomenon exists that gas loggings reflect low gas bearing in some of the wells and the gas is dominated by nitrogen rather than hydrocarbon gas. The study of nitrogen concentration in shale gas

Influence of Flaw Inclination Angle on Unloading Responses of Brittle Rock in Deep Underground

open access: yesGeofluids, Volume 2019, Issue 1, 2019., 2019
Excavation unloading is a primary stress condition for engineering rock mass in deep underground. Based on the unloading stress condition during the excavation operation, this paper employed a distinct element method (DEM) to simulate the unloading responses of intact and preflawed rock specimens.
