Using surface particles to interact with complex everyday surfaces
… digital content onto any complex physical surface. While devices like the IPod and IPad have received tremendous commercial success, the interaction capabilities for users are still limited to a small mobile screen. As projectors continue to decrease in size, cost and power consumption, …

Insulator-insulator Contact Charging As A Function Of Pressure
… research has been performed that shows that the surface charge on an insulator after triboelectric charging with another insulator is rapidly dissipated with lowered atmospheric pressure. This pressure discharge is consistent with surface ions being evaporated off the surface once their vapor …

Investigation into smoothed particle hydrodynamics for non-newtonian droplet modelling
… a non-Newtonian pressure correction method with surface tension. Three experiments were performed to analyze the different aspects of SPH. From the results of the experiments, we concluded that this method can produce stable simulations if an artificial viscosity model is included, a third-order …

Numerical and experimental evaluation of the erodibility of particle packings with surface treatments and spring reinforcements using the discrete element method
… particle packings subjected to added mass surface treatments was explored using a combination of physical flume experiments and the discrete element method (DEM). Packings composed of spherical glass particles, with and without surface treatments and angled at two different slopes, were …

Augmenting complex surfaces with projector-camera systems
… interaction with appropriated, everyday, passive surfaces. Instead of restricting interaction to a single rectangle, projection-based augmented reality makes interaction ubiquitous, taking the computer out of the box. Extending interaction to almost any surface enables new possibilities in a host …

Semiclassical studies of decoherence produced by scattering
The conventional notion of coherent atom-surface scattering originates from the existence of Bragg peaks in elastic scattering. The helium atom acts as a quantum mechanical matter wave that is coherent with itself; the well-defined phase relationship of the particle beam at the different spatial …

Numerical Investigation of breaking waves and their interations with structures using MLPG_R method
… developed technique for identifying the free surface particles is presented, which is much more robust than those existing in literature. A semi-analytical method for numerical evaluation of integrals in a local domain and on its surface is presented to form the matrix for the algebraic …

ISPH Modelling of Solitary Wave Interaction with Permeable Beaches
… are more suitable for simulating violent free-surface flows. Smooth Particle Hydrodynamics (SPH) is a meshless and particle method, which can be applied to simulations of moving free surface flows with porous structures. This thesis presents an incompressible SPH (ISPH) model that can simulate …
