On Fully Practical Finite Element Approximations of Degenerate Cahn-Hilliard Systems (2001)
Journal Article

We consider a model for phase separation of a multi-component alloy with non-smooth free energy and a degenerate mobility matrix. In addition to showing well-posedness and stability bounds for our approximation, we prove convergence in one space dime...

The quantitative assessment of UHMWPE wear debris produced in hip simulator testing : the influence of head material and roughness, motion and loading (2001)
Journal Article

Biomaterial wear particles are known to provoke a foreign-body reaction when released from total joint prostheses. Considerable effort is being invested in the search for materials which, by wearing less, will release fewer particles. In this researc...

Uniting Bose-Einstein Condensates in Optical Resonators. (2001)
Journal Article

The relative phase of two initially independent Bose-Einstein condensates can be laser cooled to unite the two condensates by putting them into a ring cavity and coupling them with an internal Josephson junction. First, we show that this phase coolin... Read More about Uniting Bose-Einstein Condensates in Optical Resonators..

Cavity-assisted quasiparticle damping in a Bose-Einstein condensate. (2001)
Journal Article

We consider an atomic Bose-Einstein condensate held within an optical cavity and interacting with laser fields. We show how the interaction of the cavity mode with the condensate can cause energy due to excitations to be coupled to a lossy cavity mod...

Prediction of Turbomachinery Flow Physics from CFD - Review of Recent Computations of APPACET Test Cases (2001)
Journal Article

In order to maintain a competitive edge, the turbomachinery industry has to rely increasingly on design and analysis methods based on numerical simulation of flow. The European funded APPACET was set up to study the application of turbulence modellin...

Non-axisymmetric turbine end wall profiling (2001)
Journal Article

A design method for profiling the end wall to reduce secondary flow has been reported previously. A profile has been tested in the Durham Linear Cascade and the results confirmed the design method. This paper describes the design and testing of a sec... Read More about Non-axisymmetric turbine end wall profiling.

An efficient pyridine- and oxadiazole-containing hole-blocking material far organic light-emitting diodes: Synthesis, crystal structure, and device performance (2001)
Journal Article

In this paper, we focus on the synthesis and structure of the new bis(1,3,4-oxadiazole) system 2,5-bis[2-(4-tert- butylphenyl)-1,3,4-oxadiazol-5-yl]pyridine (PDPyDP). We have fabricated light-emitting diodes (LEDs) using poly[2-methoxy-5- (2-ethylhex...

Pin-on-plate studies on the effect of rotation on the wear of metal-on-metal samples (2001)
Journal Article

An important cause of osteolysis and subsequent loosening of replacement hip joints is the body's biological response to polyethylene wear debris. Interest has thus been renewed in hard bearing surfaces such as metal-on-metal implants. Tests were per...

An Improved Error Bound for a Finite Element Approximation of a Model for Phase Separation of a Multi-Component Alloy with a Concentration Dependent Mobility Matrix (2001)
Journal Article

Using a slightly different discretization scheme in time and adapting the approach in Nochetto et al. (1998) for analysing the time discretization error in the backward Euler method, we improve on the error bounds derived in (i) Barrett and Blowley (...

Metal ion sensing using ultrathin organic films prepared by the layer-by-layer adsorption technique (2001)
Journal Article

Bilayer films of poly(ethyleneimine) and poly(ethylene-co-maleic acid) have been prepared using the layer-by-layer assembly technique. These films have been characterized using surface plasmon resonance (SPR). Exposure to aqueous solutions of metal a...

Raman and finite-element analysis of a mechanically strained silicon microstructure (2001)
Journal Article

Raman microspectroscopy has been used to determine the volumetric micro-strain distribution in mechanically stressed silicon microstructures. Data are presented as strain images with a spatial resolution of around 0.8 µm. A useful correlation is demo...

Constructing Hardware/software Interface Using Protocol Converters (2001)
Presentation / Conference Contribution

Hardware/software partition is a critical phase in hardware/software co-design. This paper proposes a hybrid partitioning framework, in which we design a set of protocol converters to construct the nterface component between the hardware and software...
