Numerical Simulation of Piles in a Liquefied Slope Using a Modified Soil–Pile Interface Model
Applied Sciences, 2023 The liquefaction of soil surrounding a pile significantly affects the dynamic interaction between the soil and the pile. In particular, liquefaction of the sloping ground can induce permanent deformation and a bending moment on the pile due to the ...

A Novel Centrifugal Diffuser Test Device [PDF]
Volume 1: Aircraft Engine; Turbomachinery, 1985 A large scale (2 inch wide test vanes at 50-inch inlet diameter), low speed (100–200 ft/sec) steady flow radial cascade wind tunnel for diffuser studies was designed, built and tested. The apparatus was shown to provide flow angles from radial in the range 58–72 degrees with suitable spanwise profiles.

Influence of Centrifuge Temperature on Routine Coagulation Testing [PDF]
Clinical Chemistry, 2006 A standardized procedure for specimen collection is essential to achieve accurate and reliable coagulation measurements (1). Efforts have been made to identify the most suitable procedures for collecting, handling, and storing specimens for coagulation testing (2)(3)(4)(5)(6), including a recommendation that samples be centrifuged at room temperature ...

WAVE PROPAGATION THROUGH SOILS IN CENTRIFUGE TESTING [PDF]
Journal of Earthquake Engineering, 1998 Wave propagation phenomena in soils can be experimentally simulated using centrifuge scale models. An original excitation device (drop-ball arrangement) is proposed to generate short wave trains. Wave reflections on model boundaries are taken into account and removed by homomorphic filtering. Propagation is investigated through dispersion laws.
