Multiple agents, equipped with a feature-based phonetic model and a connectionist cognitive model, interact via the naming game , with lexicon formation and change as emergent properties of this complex adaptive system. We present a new description of the naming game, situating it as a general, implementation-independent paradigm. Our addition of richer phonetic and cognitive models provides th...

Exposed root surfaces frequently exhibit non-carious notches representing material loss by abrasion, erosion, and/or abfraction. Although a contribution from mechanical stress is often mentioned, no definitive proof exists of a cause-effect relationship. To address this, we examined dimensional changes in dentin subjected to cyclic fatigue in two different pH environments. Human dentin cantilev...

The risk management paradigm has been proposed by a number of national and international research organisations as a useful framework for identifying robust decisions in the face of the inherent uncertainties associated with climate variability and anthropogenic climate change. The pursuance of risk management hinges on four fundamental considerations: a) a threshold for a particular system of ...

Phase interfaces in melting and solidification processes are strongly affected by the presence of convection in the liquid. One way of modeling their transient evolution is to couple an incompressible flow model to an energy balance in enthalpy formulation. Two strong nonlinearities arise, which account for the viscosity variation between phases and the latent heat of fusion at the phase interf...

Title of dissertation: DIRECT NUMERICAL SIMULATION OF INCOMPRESSIBLE MULTIPHASE FLOW WITH PHASE CHANGE Moon Soo Lee, Doctor of Philosophy, 2015 Dissertation directed by: Professor Amir Riaz Department of Mechanical Engineering Phase change problems arise in many practical applications such as air-conditioning and refrigeration, thermal energy storage systems and thermal management of electronic...

Soil erosion is triggered by rainfall through the detachment of soil particles and their transport downslope, playing a key role in models. Together with vegetation cover, temporal dynamic factor, inducing corresponding time variations rates. Under current climate change, also changing its characteristics our study aimed to reveal whether these changes will significantly affect erosivity Romani...
