Incompressible Navier-Stokes equation solvers based on lattice Boltzmann relaxation systems. (2008)
Presentation / Conference Contribution
Banda, M., Seaid, M., & Teleaga, I. (2008, December). Incompressible Navier-Stokes equation solvers based on lattice Boltzmann relaxation systems

In this talk some recent numerical results based on discrete-velocity relaxation systems will be presented. Discrete-velocity equations are derived from continuous Boltzmann-type equations with appropriate approximations suitable for incompressible f...

Maximizing supermodular functions on product lattices, with application to maximum constraint satisfaction (2008)
Journal Article
Krokhin, A., & Larose, B. (2008). Maximizing supermodular functions on product lattices, with application to maximum constraint satisfaction. SIAM Journal on Discrete Mathematics, 22(1), 312-328. https://doi.org/10.1137/060669565

Recently, a strong link has been discovered between supermodularity on lattices and tractability of optimization problems known as maximum constraint satisfaction problems. This paper strengthens this link. We study the problem of maximizing a superm...

Journal Article
Walton, J. (2008). The changing use of electronic document delivery in the inter-library loan service : a survey. https://doi.org/10.1108/02641610810856381

Purpose – The purpose of this paper is to outline findings of a recent MSc study into electronic article provision in interlending and document supply presented to the Robert Gordon University in June 2007. Design/methodology/approach – The paper is... Read More about The changing use of electronic document delivery in the inter-library loan service : a survey.

Slab stiffness control of trench motion: Insights from numerical models (2008)
Journal Article
Di Giuseppe, E., van Hunen, J., Funiciello, F., Faccenna, C., & Giardini, D. (2008). Slab stiffness control of trench motion: Insights from numerical models. Geochemistry, Geophysics, Geosystems, 9(2), https://doi.org/10.1029/2007gc001776

Subduction zones are not static features, but trenches retreat (roll back) or advance. Here, we investigate the dominant dynamic controls on trench migration by means of two- and three-dimensional numerical modeling of subduction. This investigation...

A conceptual framework for understanding semi-arid land degradation: ecohydrological interactions across multiple-space and time scales (2008)
Journal Article
Turnbull, L., Wainwright, J., & Brazier, R. (2008). A conceptual framework for understanding semi-arid land degradation: ecohydrological interactions across multiple-space and time scales. Ecohydrology, 1(1), 23-34. https://doi.org/10.1002/eco.4

Land degradation is a problem prolific across semi‐arid areas worldwide. Despite being a complex process including both biotic and abiotic elements, previous attempts to understand ecosystem dynamics have largely been carried out within the disparate...

Comparing alternative approaches to measuring the geographical accessibility of urban health services: Distance types and aggregation-error issues (2008)
Journal Article
Apparicio, P., Abdelmajid, M., Riva, M., & Shearmur, R. (2008). Comparing alternative approaches to measuring the geographical accessibility of urban health services: Distance types and aggregation-error issues. International Journal of Health Geographics, 7(7), Article 7. https://doi.org/10.1186/1476-072x-7-7

Background Over the past two decades, geographical accessibility of urban resources for population living in residential areas has received an increased focus in urban health studies. Operationalising and computing geographical accessibility measures...

We investigate the routing and transfer of particulate organic carbon (POC) from the western Southern Alps, New Zealand, using organic carbon (Corg) and nitrogen (Norg) concentrations and stable carbon isotopes (δ¹³Corg). In this active mountain belt... Read More about Riverine particulate organic carbon from an active mountain belt: importance of landslides.

Structural chemistry of (PPh4)2M(WS4)2 materials. (2008)
Journal Article
Crossland, C. J., Evans, I. R., & Evans, J. S. O. (2008). Structural chemistry of (PPh4)2M(WS4)2 materials. Dalton Transactions, 2008(12), 1597-1601. https://doi.org/10.1039/b716407f

In this paper we discuss the structural chemistry of (PPh4)2M(WS4)2 (M = Co, Ni, Zn) materials. For M = Ni we and others have been unable to grow single crystals and we report the structure determination from powder diffraction. The material is tricl...

Nonlinear Fluid Dynamics from Gravity (2008)
Journal Article
Bhattacharyya, S., Minwalla, S., Hubeny, V. E., & Rangamani, M. (2008). Nonlinear Fluid Dynamics from Gravity. Journal of High Energy Physics, 2008(02), Article 045. https://doi.org/10.1088/1126-6708/2008/02/045

Black branes in AdS5 appear in a four parameter family labeled by their velocity and temperature. Promoting these parameters to Goldstone modes or collective coordinate fields—arbitrary functions of the coordinates on the boundary of AdS5—we use Eins...
