Intelligent Models Applied to Elastic Modulus of Jointed Rock Mass

, 2018
Elastic Modulus (Ej) of jointed rock mass is a key parameter for deformation analysis of rock mass. This chapter adopts three intelligent models {Extreme Learning Machine (ELM), Minimax Probability Machine Regression (MPMR) and Generalized Regression ...

Theoretical Methods for Wave Propagation across Jointed Rock Masses [PDF]

, 2010
Different methods are presently available for the analysis of wave propagation across jointed rock masses with the consideration of multiple wave reflections between joints. These methods can be divided into two categories.

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Parametric analysis of tunnel behavior in jointed rock

, 2012
Jointed rock masses are often encountered during underground excavation. Many failures of underground openings, during excavation and in operation, are reported closely related to joints.This paper investigates the impact of three basic factors affecting
