Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features.

This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less
Diagnosis of Reference Flow Control Alerts for the Identification of Malicious Event Sequences (DiagRF). There are a reported two billion computer attacks worldwide per year. Many of these attacks require a skilled human to decipher them and to develop the "signatures" by which they can be detected.

There are a reported two billion computer attacks worldwide per year. Many of these attacks require a skilled human to decipher them and to develop the "signatures" by which they can be detected. The main outcome of this project will be fundamental knowledge regarding how information flows can be tracked and then forensically analysed in a distributed computer system or network in order to enable the automatic characterization of certain classes of attacks. This new approach will enable the automatic development of attack signatures and thus the detection of such attacks. The project will lead to the development of a prototype which implements the automatic analysis and characterization of such attacks to provide proof of concept.Read moreRead less

Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated. The inorganic contaminants in sediments can be released back into the water body through mass transfer processes. The mass transfer rate is largely controlled by the wave-driven seepage flux across the seabed. Quantification of this flux is thus a key factor in modelling water quality of coastal water bodies. This project aims to: (1) develop models forwave-induced seepage flux within sediments and ....Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated.

Tidal watertable fluctuation in a sandy ocean beach. Tidal dynamics in a sandy beach is important for erosion, saltwater intrusion and biological activities. Most previous researches were based on linearised shallow flow, ignoring capillary effects and soil behaviour, which are particularly important for a sandy beach. In this project, we propose to establish an analytical approximation for the tidal watertable fluctuation in a sandy beach by incorporate the capillary effects and soil behaviour. ....Tidal watertable fluctuation in a sandy ocean beach.
