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)

Due to the heterogeneity and geographically distribution of Grid resources, effective and efficient task scheduling algorithms are required. Resource load balancing and minimizing makespan are the fundamental goals of effective and efficient task scheduling. It becomes more complicated when various QoS demands arise from users. In this paper, we have(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)

Recently developed architecture such as Compute Unified Device Architecture (CUDA) allows us to exploit the computational power of Graphics Processing Units (GPU). In this paper we propose an algorithm for implementation of Cover tree, accelerated on the graphics processing unit (GPU). The existing algorithm for Cover Tree implementation is for single core(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)
