Nonlinear consolidation models of clay with time dependant drainage properties

Foam consolidation and drainage.

A theoretical model of foam as a consolidating continuum is proposed. The general model is applied to foam in a gravity settler. It is predicted that liquid drainage from foam in a gravity settler begins with a slow drainage stage. Next, a stage with faster drainage occurs where the drainage rate doubles compared to the initial stage. The experiments conducted within the framework of this work ...

On the Thermal Consolidation of Boom Clay

When a mass of saturated clay is heated, as in the case of host soils surrounding nuclear waste disposals at great depth, the thermal expansion of the constituents generates excess pore pressures. The mass of clay is submitted to gradients of pore pressure and temperature, to hydraulic and thermal flows, and to changes in its mechanical properties. In this work, some of these aspects were exper...

Discrete Time Dynamical Models and Their Quantum Like Context Dependant Properties

In this paper we demonstrate that a quantum-like interference pattern could appear as a statistical effect of interference of deterministic particles, i.e. particles that have trajectories and obey deterministic dynamical equations, if one introduces a discrete time. The nature of the resulting interference picture does not follow from the geometry of force field, but is strongly attached to th...

Comparison of Two Nonlinear Radiation Models for Agricultural Subsurface Drainage

Comparison of time to the event and nonlinear regression models in the analysis of germination data

Extended abstract   Introduction: Numerous studies are being carried out to reveal the effects of different treatments on the germination of seeds from various plants. The most commonly used method of analysis is the nonlinear regression which estimates germination parameters. Although the nonlinear regression has been performed based on different models, some serious problems in its structure...
