In this paper, we optimize user scheduling, power allocation and beamforming in distributed multiple-input multiple-output (MIMO) networks implementing user-centric clustering. We study both the coherent non-coherent transmission modes, formulating a weighted sum rate maximization problem for each; finding optimal solution to these problems is known be NP-hard. use tools from fractional program...

INTRODUCTION Patient appointment systems are of great importance for efficiently managing outpatient clinics as well as patient satisfaction as an indirect indicator for quality care rendered. PURPOSE To describe the hourly block and standard sequential scheduling appointment systems at two different hospitals, as well as to assess the patients' opinions regarding their waiting time in both s...

In order to establish a production plan, an open-pit mine is partitioned into a three-dimensional array of blocks. The order in which blocks are extracted and processed has a dramatic impact on the economic value of the exploitation. Since realistic models have millions of blocks and constraints, the combinatorial optimization problem of finding the extraction sequence that maximizes the profit...
