The main population centre of the volcanic Hawaiian-island chain in the north-central Pacific Ocean is on the island of Oahu (population about 900,000) (Figure 1). Oahu depends on ground water, which is mainly produced from coastal aquifers, for its potable-water supply. Oahu has high rainfall, highly permeable aquifers, and a coastal confining layer that results in high heads at the coast and ...

Puredata is used to demonstrate a exible and e cient approach to one problem in procedural game audio, that of creating footsteps. A model of ground pressure curves from bipedal movement combined with a synthesis layer and mapping of force to frictional excitement emulates the movement of actors on a surface. The speed and weight of the actor, the material composition of the ground and the work...

In this paper, we prove that quantum layers over a surface which is ruled outside a compact set, nonplanar but asymptotically flat, admit a ground state for the Dirichlet Laplacian. The work here also represents some technical progress toward resolving the conjecture that a quantum layer over any nonplanar, asymptotically flat surface with integrable Gauss curvature must possess ground state. ©...

This paper investigates the thermo-hydro-mechanical (THM) behaviour of soils subjected to seasonal temperature variations in both permafrost and seasonally frozen conditions. Numerical modelling of soil freezing and ice segregation processes is presented, and compared against small-scale physical modelling experiments. The coupled THM model presented, which is solved by way of a transient finit...

An investigation of the Planetary Boundary Layer (PBL) height evolution over Greece, during the solar eclipse of 29 March 2006, is presented. Ground based observations were carried out using lidar detection and ranging devices and ground meteorological instruments, to estimate the height of the mixing layer (ML) before, during and after the solar eclipse in northern and southern parts of Greece...
