  • Obsolescence management for long-life contracts: State of the art and future trends 
    Romero Rojo, Francisco Javier; Roy, Rajkumar; Shehab, Essam (Springer Science Business Media, 2009-08-31)
    This paper provides a comprehensive literature review on the problem of obsolescence in “sustainment-dominated systems” that require support for many decades. Research on this topic continues to grow as a result of the ...
  • Obsolescence Risk Assessment Process Best Practice 
    Romero Rojo, Francisco Javier; Roy, Rajkumar; Kelly, S. (Institute of Physics (IoP), 2013-01-22)
    A component becomes obsolete when it is no longer available from the original manufacturer to the original specification. In long-lifecycle projects, obsolescence has become a major problem as it prevents the maintenance ...
  • Off-line particle size analysis of digested sludge. 
    Houghton, Jennifer I.; Stephenson, Tom (Elsevier Science B.V., Amsterdam., 2002-11-01)
    Particle size analysis was carried out on six samples of digested sludge using laser diffraction. The digested sludge was produced in laboratory-scale reactors under different feed regimes based on a mixture of primary ...
  • On adsorption-induced denaturation of folded proteins. 
    Fernández, Ariel; Ramsden, Jeremy J. (Jointly by, Collegium Basilea (Institute of Advanced Study) and Association of Modern Scientific Investigation., 2001-12)
    In the absence of intramolecular long range interactions, the extended local conformation of a peptide chain is entropically favoured over compact ones, since the area of the Ramachandran basin of attraction is larger ...
  • On Surface Grind Hardening Induced Residual Stresses 
    Salonitis, Konstantinos (Elsevier BV, 2014-06-02)
    Grind hardening process utilizes the heat generated in the grinding area for the surface heat treatment of the workpiece. The workpiece surface is heated above the austenitizing temperature by using large values of depth ...
  • On the Effect of Ageing on the Erosion of EB-PVD TBCs 
    Wellman, R. G.; Nicholls, John R. (Elsevier Science B.V., Amsterdam., 2004-01-30)
    Thermal barrier coatings have been used in gas turbine engines for some four decades, and the erosion resistance of these coatings has been well documented over the years by various different groups. However, as far as ...
  • On the integration of the CAx systems towards sustainable production 
    Salonitis, Konstantinos; Stavropoulos, Panagiotis (Elsevier BV, 2013-12-31)
    Achieving sustainable development and succeeding in sustainable production requires changes in industrial processes, type and quantity of resources used, treatment of waste, control of emissions, and finally in the final ...
  • On-line measurement of soil properties without direct spectral response in near infrared spectral range 
    Marin-González, O.; Kuang, Boyan Y.; Quraishi, M. Z.; Munoz-Garcia, M. A.; Mouazen, Abdul Mounem (Elsevier Science B.V., Amsterdam., 2013-08-01)
    So far, the majority of reports on on-line measurement considered soil properties with direct spectral responses in near infrared spectroscopy (NIRS). This work reports on the results of on-line measurement of soil properties ...
  • Onset of methanogenesis in landfilled MSW. 
    Barry, D. L.; Smith, Richard; Harries, C. (The Waste Conference Limited, 2004-09)
    This research project (Barry et al. 2003, 2004a and 2004b) assessed the time period for the onset of methanogenesis and examined the scale of methane (CH4) fluxing from waste surfaces during the waste placement phases ...
  • Open access 
    Ramsden, Jeremy J. (Collegium Basilea & AMSI, 2004-09)
    Editorial
  • Open standard, open source and peer-to-peer tools and methods for collaborative product development 
    Aziz, Hayder; Gao, James X.; Maropoulos, Paul G.; Cheung, Wai M. (Elsevier, 2005-04)
    This paper reports on a collaborative product development and knowledge management platform for small to medium enterprises. It has been recognised that current product lifecycle management (PLM) implementations are document ...
  • The Open2-Innova8ion Tool - A Software Tool for Rating Organisational Innovation Performance 
    Caird, Sally P.; Hallett, Stephen H.; Potter, Stephen (Elsevier Science B.V., Amsterdam., 2013-10-01)
    The Open2-Innova8ion Tool is an interactive, multi-media, web-based software tool for rating organisational innovation performance. This tool was designed for organisations to use as an adaptation of the European Commission's ...
  • Operating strategies for variable-flow sequencing batch reactors. 
    Bungay, S.; Humphries, M.; Stephenson, Tom (Blackwell Publishing, 2007-03)
    Sequencing batch reactors (SBRs) are variable-volume, non-steady-state, suspended-growth biological wastewater treatment reactors. The treatment process is characterised by a repeated treatment cycle consisting of a series ...
  • Optimal design for inspection and maintenance policy based on the CCC chart 
    Chan, Ling-Yau; Wu, Shaomin (Elsevier Science B.V., Amsterdam., 2009-10-01)
    In this paper, the concept of cumulative count of conforming chart (CCC chart) is applied in inspection and maintenance planning for systems where minor inspection, major inspection, minor maintenance and major maintenance ...
  • Optimal inspection policy for three-state systems monitored by control charts 
    Wu, Shaomin; Wang, Wenbin (Elsevier Science B.V., Amsterdam., 2011-08-01)
    This paper presents the formulations of the expected long-run cost per time unit for a system monitored by a static control chart and by an adaptive control chart respectively. The static chart has a fixed sampling ...
  • Optimal inspection policy for three-state systems monitored by variable sample size control charts 
    Wu, Shaomin (Springer Science Business Media, 2011-07-01)
    This paper presents the expected long-run cost per unit time for a system monitored by an adaptive control chart with variable sample sizes: if the control chart signals that the system is out of control, the sampling ...
  • Optimisation of business process designs: An algorithmic approach with multiple objectives. 
    Vergidis, K.; Tiwari, Ashutosh; Majeed, Basim; Roy, Rajkumar (Elsevier, 2007-09)
    Most of the current attempts for business process optimisation are manual without involving any formal automated methodology. This paper proposes a framework for multi-objective optimisation of business process designs. ...
