    In multi-stage radiotherapy, a patient is treated in several stages separated by weeks or months. This regimen has been motivated mostly by radiobiological considerations, but also provides an approach to reduce normal ...
  • Failure Diagnosis Using Deep Belief Learning based Health State Classification 

    Tamilselvan, Prasanna; Wang, Pingfeng (Elsevier, 2013-03-13)
    Effective health diagnosis provides multifarious benefits such as improved safety, improved reliability and reduced costs for operation and maintenance of complex engineered systems. This paper presents a novel multi-sensor ...
  • A first best toll pricing framework for variable demand traffic assignment problems 

    Yildirim, Mehmet Bayram; Hearn, Donald W. (Elsevier, 2005)
    In this paper, we present a toll pricing framework for a general variable demand traffic assignment problem with side constraints, where the demand between an origin destination pair is a function of the least total travel ...
  • Food vs. biofuel: an optimization approach to the spatio-temporal analysis of land-use competition and environmental impacts 

    Cobuloglu, Halil I.; Bueyuektahtakin, I. Esra (Elsevier Ltd., 2015-02-15)
    Biofuel production from food crops leads to debates about the increase in food prices and security of the food supply. On the other hand, biofuels derived from cellulosic (energy) crops offer positive environmental impacts. ...

    Masud, Abu S.M. (Elsevier Ltd., 1985)
    Plant labor productivity index, defined as the ratio of the standard labor hours and actual labor hours, is an important factor in the determination of the future manpower needs at Cessna Aircraft Co. (Pawnee Division). ...
  • A framework to minimise total energy consumption and total tardiness on a single machine 

    Mouzon, Gilles C.; Yildirim, Mehmet Bayram (Taylor & Francis, 2008)
    A great amount of energy is wasted in industry by machines that remain idle due to underutilisation. A way to avoid wasting energy and thus reducing the carbon print of an industrial plant is to consider minimisation ...
