An evaluation of the tribological performance of zirconia and CoCrMo femoral heads (1999)
Journal Article
Smith, S., Elfick, A., & Unsworth, A. (1999). An evaluation of the tribological performance of zirconia and CoCrMo femoral heads. Journal of Materials Science, 34(21), 5159-5162. https://doi.org/10.1023/a%3A1004737526529

Five new zirconia, five new CoCrMo and three explanted CoCrMo femoral heads were wear-tested in bovine serum for five million cycles using the Durham Hip Joint Wear Simulator. Wear was measured gravimetrically and surface topography with a 3D non-con... Read More about An evaluation of the tribological performance of zirconia and CoCrMo femoral heads.

Measurement and Computation of Energy Separation in the Vortical Wake Flow of a Turbine Nozzle Cascade (1999)
Journal Article
Carscallen, W., Currie, T., Hogg, S., & Gostelow, J. (1999). Measurement and Computation of Energy Separation in the Vortical Wake Flow of a Turbine Nozzle Cascade. Journal of Turbomachinery, 121(4), 703-708. https://doi.org/10.1115/1.2836723

This paper describes the observation, measurement, and computation of vortex shedding behind a cascade of turbine nozzle guide vanes that have a blunt trailing edge. At subsonic discharge speeds, periodic wake vortex shedding was observed at all time...

Using the approach in [5] for analysing time discretization error and assuming more regularity on the initial data, we improve on the error bound derived in [2] for a fully practical piecewise linear finite element approximation with a backward Euler...

Finite element approximation of a model for phase separation of a multi-component alloy with nonsmooth free energy and a concentration dependent mobility matrix. (1999)
Journal Article

Mathematical Models and Methods in Applied Sciences, 9(5), 627-663. https://doi.org/10.1142/s0218202599000336

We consider a model for phase separation of a multi-component alloy with nonsmooth free energy and a concentration dependent mobility matrix. In particular we prove that there exists a unique solution for sufficiently smooth initial data. Further, we...

Using the approach of Rulla (1996 SIAM J. Numer. Anal. 33, 68-87) for analysing the time discretization error and assuming more regularity on the initial data, we improve on the error bound derived by Barrett and Blowey (1996 IMA J. Numer.
