The complex business strategies of cloud services make Job scheduling a challenging issue. The mapping of user jobs onto a computing resource to achieve maximum benefit, satisfying the varying QoS of user's jobs, is the ultimate goal of a cloud provider. As this scheduling problem belongs to the family of combinatorial problems, it cannot be formulated as a(More)
In this study the dosimetric characteristics of 120-leaf multileaf collimators (MLCs) were evaluated for 6-MV and 18-MV photon beams. The dose rate, percentage depth dose, surface dose, dose in the build-up region, beam profile, flatness, symmetry, and penumbra width were measured using three field-defining methods: (i) 'Jaw only', (ii) 'MLC only', and(More)
The aim of this study was to evaluate the breast dose heterogeneity in CT-based radiotherapy treatment planning and to correlate with breast parameters. Also, the number of slices required for treatment planning in breast cancer by tangential field technique has been assessed by comparing the treatment plans according to International Commission on(More)
One of the important aspects in digital video applications is spatial and temporal characteristic. A very little progress has been achieved on spatio-temporal modeling of video data. In this paper, we present a fuzzy spatio-temporal model for video content description that supports spatio-temporal queries. Fuzzy definitions and membership functions of(More)
