background: an effective polymer gel dosimeter can be fabricated by varying the composition of its chemical components. materials and methods: the magat gel dosimeter formulations that used different compositions of methacrylic acid (maa) and gelatin were extensively investigated in the present study according to the r2–dose response and r2–dose sensitivity. the irradiation of magat gel was per...

In this paper we describe the proof of an optimisation that can be applied to tuple space based run-time systems (as used in Linda). The optimisation allows, under certain circumstances, for a tuple that has been destructively removed from a shared tuple space (for example, by a Linda in) to be returned as the result for a non-destructive read (for example, a Linda rd) for a di erent process. T...

This paper introduces a real, unmodified Many-Objective optimisation problem for use in optimisation algorithm benchmarking. The radar waveform design problem has 9 objectives and an integer decision space that can be scaled from 4 to 12 decision variables. Proprietary radar waveform design software has been encapsulated in a fast and portable form to facilitate research groups in studying high...

BACKGROUND Modern intensity modulated radiotherapy (IMRT) mostly uses iterative optimisation methods. The integration of machine parameters into the optimisation process of step and shoot leaf positions has been shown to be successful. For IMRT segmentation algorithms based on the analysis of the geometrical structure of the planning target volumes (PTV) and the organs at risk (OAR), the potent...
