    Comparative studies of PST thin films as prepared by Sol-Gel, LDCVD and sputtering techniques
    (Taylor and Francis, 2002) Huang, Zhaorong; Donohue, P. P.; Zhang, Qi; Williams, D.; Anthony, C. J.; Todd, M. A.; Whatmore, Roger W.
    Lead scandium tantalate (PST) thin films for pyroelectric applications have been deposited by using liquid delivery chemical vaporise deposition (LDCVD), sputtering and sol-gel techniques. These films were annealed by using rapid thermal annealing to improve their electrical properties. Their microstructures and electrical properties such as permittivity εr, dielectric loss tanδ, pyroelectric coefficient p, and thermal detection figure of merit Fd were studied. It is suggested to use a combination of methods to depositing films and then use rapid thermal annealing to produce high quality PST thin films.

    A review of data visualization: opportunities in manufacturing sequence management.
    (Taylor and Francis, 2006-10) Sackett, Peter J.; Al-Gaylani, M. F.; Tiwari, Ashutosh; Williams, D.
    Data visualization now benefits from developments in technologies that offer innovative ways of presenting complex data. Potentially these have widespread application in communicating the complex information domains typical of manufacturing sequence management environments for global enterprises. In this paper the authors review the visualization functionalities, techniques and applications reported in literature, map these to manufacturing sequence information presentation requirements and identify the opportunities available and likely development paths. Current leading-edge practice in dynamic updating and communication with suppliers is not being exploited in manufacturing sequence management; it could provide significant benefits to manufacturing business. In the context of global manufacturing operations and broad-based user communities with differing needs served by common data sets, tool functionality is generally ahead of user application.
