Abstract: Cable shovel excavators are used for primary production of geomaterials in many surface mining operations. A major problem in excavation is the variability of material diggability, resulting in varying mechanical energy ...

Abstract: Velocity correction methods are often used in numerical models simulating fluid flows. This paper presents a new method to evaluate the velocity correction coefficient: an equation constructed from the coefficient matrix ...

Abstract: The potential for the desiccation of clay liner component of composite liners due to temperature field generated by breakdown of organic matter in municipal solid waste landfills is examined using a model proposed by Zhou ...

Abstract: Using data for the month of June from 1951 through 2000, this study examined the air?sea interactions over the North Pacific after El Niño matured during the preceding fall season. The principal findings of this work are ...

Abstract: A three-dimensional buoyancy-extended version of

Abstract: The hydraulic shovel excavator has found significant applications in surface mining, construction, and geotechnical operations due to its flexibility and mobility. The key to high availability and utilization of this shovel ...

Abstract: This study deals with two teleconnection patterns and the subsequent wave train propagations during an East Asian summer. Diagnostic results are as follows: 1) a stationary wave ray with zonal wavenumber 5 approximates the ...

Abstract: Part II presents two modeling schemes for simulating the reeling/unreeling of a pipeline, with the aim of establishing the degrading effect of the process on the structural performance of the pipeline. A three-dimensional ...
