Long-Term Evolution (LTE) networks comprising conventional cellular macrocells plus user-installed femtocells offer an economically viable solution to achieving high user capacity and upgrading to future fourth-generation systems. With the growing impetus for frequency reuse, the capacity of each user depends on not only the power spectral density of its own, but also on those of others in neighboring...
Not too bad. A rate allocation that is suboptimal with respect to a utility maximization formulation still maintains the maximum flow-level stability when the utility gap is sufficiently small, and provides a minimum size of stability region otherwise. Utility-suboptimal allocation may also enhance other network performance metrics, e.g., it may increase network throughput and reduce link saturation...
Segmentation is a fundamental problem in image processing having a wide range of applications. Image segmentation algorithms in the literature range from a cost criterion based optimization techniques to various heuristic methods. In this paper, we propose utilizing mean shift spectral clustering for perceptually better image segmentation results
