Geometrical consequences of foam equilibrium

The equilibrium consequences of indexing

We study the consequences of indexing, i.e. commiting to invest in risky assets only via the market portfolio. We extend the canonical rational expectations model (Grossman and Stiglitz, 1980) to allow for multiple assets and endowment shocks, and show that indexing imposes a negative externality on other uninformed agents. More indexing makes informed trading on the market more profitable, whi...

Computation of Equilibrium Foam Structures Using the Surface Evolver

Weaire was supported in part by the EC Science Programme, contract SC*-CT92-0777 and HCM Network Contract ERBCHRX940542. Phelan was supported in part by Shell Research (Amsterdam) and an Irish-American Partnership studentship. The Surface Evolver has been used to minimise the surface area of various ordered structures for monodisperse foam. Additional features have enabled its application to fo...

Geometrical Derivation of Equilibrium Distributions in Some Stochastic Systems

Effect of Geometrical Modeling on the Prediction of Laser-Induced Heat Transfer in Metal Foam

Over the past several decades, aluminum foam (Al-foam) has found increasing popularity in industrial applications due to its unique material properties. Unfortunately, till date Al-foam can only be affordably manufactured in flat panels, and it becomes necessary to bend the foam to the final shape that is required in engineering applications. Past studies have shown that thin cell walls crack a...

Influence of seat foam and geometrical properties on BioRID P3 kinematic response to rear impacts.

As the primary interface with the human body during rear impact, the automotive seat holds great promise for mitigation of Whiplash Associated Disorders (WAD). Recent research has chronicled the potential influence of both seat geometrical and constitutive properties on occupant dynamics and injury potential. Geometrical elements such as reduced head to head restraint, rearward offset, and incr...
