Liquefaction and Cyclic Mobility of Saturated Sands

Journal of the Geotechnical Engineering Division, 1975
Saturated sands subjected to earthquake loadings can develop two different phenomena, i.e., liquefaction and cyclic mobility. Liquefaction can develop only in loose sands and its mechanism is related to the critical state of the sand. Cyclic mobility can develop in any sand.

Unified modeling of flow liquefaction and cyclic mobility

Soil Dynamics and Earthquake Engineering, 2000
Abstract Flow liquefaction and cyclic mobility are two different phenomena that are encountered during strong earthquakes. Flow liquefaction is associated with the contractive behavior of loose granular materials and cyclic mobility is associated with the dilative response of both loose and dense granular materials at low confining stresses.

Cyclic mobility response of a dense sand stratum

Computers and Geotechnics, 1991
Abstract The cyclic mobility response of a dense sand stratum is examined using a semi-empirical effective stress model. The model is based on two families of intersecting yield loci, one for loading and the other for unloading. The yield loci are generated from Cam Clay type energy balance equations and the associated flow rule.

Cyclic Pursuit of mobile robots: A linear approach

2017 IEEE International Conference on Signal Processing, Informatics, Communication and Energy Systems (SPICES), 2017
Cyclic Pursuit is a distributed control law wherein competitive or non-cooperative local interactions among agents are used to achieve cooperative global behaviors. Due to their inherent nonlinear dynamics, unicycle models are widely used in designing cyclic pursuit control laws for mobile robots. This paper introduces a simplified technique for design

Optimization of a cyclic queue for mobile dentistry

Proceedings of the 6th International Conference on Queueing Theory and Network Applications, 2011
We consider the allocation of mobile dentistry resources to a scattered population. A cyclic queueing network is used to model the allocation process. The resulting model may be transformed to a geometric program. Numerical results are given.

Cyclic ADP-ribose: A calcium mobilizing metabolite of NAD+

Molecular and Cellular Biochemistry, 1994
Mobilization of Ca+2 from intracellular stores is a signalling mechanism that is of fundamental importance to many cellular processes. It is mediated by two major mechanisms, the inositol 1,4,5-trisphosphate pathway and the Ca+2-induced Ca+2 release process.

Constitutive Modeling of Flow Liquefaction and Cyclic Mobility

Computer Simulation of Earthquake Effects, 2000
Flow liquefaction is due to contractive response of loose granular soils, while cyclic mobility is related to both contractive and dilative response of granular soils. These two failure mechanisms may occur in a single soil, depending on the density and confining pressure applied.
