Testing for Bubbles and Change–Points

A model for a financial asset is constructed with two types of agents, who differ in terms of their beliefs. The proportion of the two types changes over time according to stochastic processes which model the interaction between the agents. Agents do not persist in holding “wrong” beliefs and bubble–like phenomena in the asset price occur. We consider tests for detecting bubbles in the conditio...

Phase diagrams for sonoluminescing bubbles

Sound driven gas bubbles in water can emit light pulses. This phenomenon is called sonoluminescence ~SL!. Two different phases of single bubble SL have been proposed: diffusively stable and diffusively unstable SL. We present phase diagrams in the gas concentration versus forcing pressure state space and also in the ambient radius versus gas concentration and versus forcing pressure state space...

Multi-layered folding with voids.

In the deformation of layered materials such as geological strata, or stacks of paper, mechanical properties compete with the geometry of layering. Smooth, rounded corners lead to voids between the layers, while close packing of the layers results in geometrically induced curvature singularities. When voids are penalized by external pressure, the system is forced to trade off these competing ef...
