SUMMARY:Guy Nason (Royal Statistical Society Vice President for Academic Affairs; University of Bristol)
DESCRIPTION:Title: Network Time Series \nAbstract: \n A network time series is a multivariate time series where the individual series are known to be linked by some underlying network structure. Sometimes this network is known a priori\, and sometimes the network has to be inferred\, often from the multivariate series itself. Network time series are becoming increasingly common\, long\, and collected over a large number of variables. We are particularly interested in network time series whose network structure changes over time. \n We describe some recent developments in the modeling and analysis of network time series via network autoregressive integrated moving average (NARIMA) process models. NARIMA models provide a network extension to a familiar environment that can be used to extract valuable information and aid prediction. As with classical ARIMA models\, trend can impair the estimation of NARIMA parameters. The scope for trend removal is somewhat wider with NARIMA models and we exhibit some possibilities. \n We will illustrate the operation of NARIMA modeling on some real data sets. \n This is joint work with Kathryn Leeming (Bristol)\, Marina Knight (York) and Matt Nunes (Lancaster). \n

SUMMARY:Alan Compelli (Cork)
DESCRIPTION:Title: Soliton fission in a fluid of non-uniform depth\nAbstract: A surface water wave over a bed of non-uniform depth is considered. The fluid is incompressible\, inviscid and irrotational. The Hamiltonian is determined in terms of wave-only quantities using a Dirichlet-Neumann operator. By introducing an appropriate scaling regime\, and considering the bottom to vary slowly\, a KdV equation with variable coefficients is derived. A one-soliton solution approaching a ramp on the seabed is then considered and numerical results demonstrate the effect the ramp shape has on the birth of new solitons as the soliton passes over it. \n

SUMMARY:Ruaa Wana (Plymouth)
DESCRIPTION:Title: Smoothed Particle Hydrodynamics (SPH) Modelling of Tsunami Waves Generated by a Fault Rupture \nSmoothed Particle Hydrodynamics (SPH) is a meshfree\, Lagrangian\, particle method. It is particularly well suited to simulating flow problems that have large deformations or contain free surfaces. In this talk we use a single phase weakly compressible SPH model to simulate a dam break flow and the flow that occurs in experimental models of Tsunamis generated by a fault rupture. The experiments have been carried out at University of Plymouthâ€™s COAST laboratory. \n
