Finite element modelling of unsaturated soils using a modified version of the Barcelona Basic Model [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper, unsaturated soil behaviour is numerically simulated using a modified version of the Barcelona Basic Model. The model has been implemented as a User-Defined Soil Model (UDSM) in the finite element code PLAXIS.

Subsurface exolife [PDF]

open access: yesInternational Journal of Astrobiology, 2018
AbstractWe study the prospects for life on planets with subsurface oceans, and find that a wide range of planets can exist in diverse habitats with ice envelopes of moderate thickness. We quantify the energy sources available to these worlds, the rate of production of prebiotic compounds, and assess their potential for hosting biospheres. Life on these

Subsurface Texture Mapping [PDF]

open access: yesIEEE Computer Graphics and Applications, 2006
Subsurface scattering within translucent objects is a complex phenomenon. Designing and rendering this kind of material requires a faithful description of their aspects as well as a realistic simulation of their interaction with light. This paper presents an efficient rendering technique of multilayered translucent objects.

Machine learning application for prediction of sonic wave transit time - A case of Niger Delta basin

open access: yesResults in Engineering, 2023
Sonic wave transit times are the major logs for estimating pertinent geomechanical parameters including overburden stress, pore pressure, effective stress, and unconfined compressible strength among others.

Automated Cloud Based Long Short-Term Memory Neural Network Based SWE Prediction

open access: yesFrontiers in Water, 2020
Snow derived water is a critical component of the US water supply. Measurements of the Snow Water Equivalent (SWE) and associated predictions of peak SWE and snowmelt onset are essential inputs for water management efforts.

A Comparative Study on the Dynamic Tensile Strength Evaluation Method of Rock Materials

open access: yesShock and Vibration, 2023
The representative calculation methods of dynamic tensile strength applied to the spalling test are comparatively reviewed in the same experimental cases. The results are compared with those of the ISRM suggested dynamic BD method.

Subsurface Topographic Modeling Using Geospatial and Data Driven Algorithm

open access: yesISPRS International Journal of Geo-Information, 2021
Infrastructures play an important role in urbanization and economic activities but are vulnerable. Due to unavailability of accurate subsurface infrastructure maps, ensuring the sustainability and resilience often are poorly recognized.

Developments in 3D Visualisation of the Rail Tunnel Subsurface for Inspection and Monitoring

open access: yesApplied Sciences, 2022
Railway Tunnel SubSurface Inspection (RTSSI) is essential for targeted structural maintenance. ‘Effective’ detection, localisation and characterisation of fully concealed features (i.e., assets, defects) is the primary challenge faced by RTSSI engineers,

Methodological approaches to planning remediation actions on military territories contaminated with petroleum products

open access: yesМінеральні ресурси України, 2023
This paper describes the urgent problem of remediation of the subsurface contaminated with petroleum products. A strategy for the control of petroleum contamination of the subsurface, which should be based on risk assessment and management, is proposed ...
