Mixed-integer polynomial programming (MIPP) problems are one class of mixed-integer nonlinear programming (MINLP) problems where objective function and constraints are restricted to the polynomial functions. Although the MINLP problem is NP-hard, in special cases such as MIPP problems, an efficient algorithm can be extended to solve it. In this research, we propose an algorit...

Energy disaggregation, known in the literature as Non-Intrusive Load Monitoring (NILM), is task of inferring energy consumption each appliance given aggregate signal recorded by a single smart meter. In this paper, we propose novel two-stage optimization-based approach for disaggregation. first phase, small training set consisting disaggregated power profiles used to estimate parameters and sta...

This paper proposes a new challenging optimization problem, called COOLING-AWARE WORKLOAD PLACEMENT PROBLEM, that looks for a workload placement that optimizes the overall data center power consumption given by the sum of the server power consumption and of the computer room air conditioner power consumption. We formulate CWPP as a Mixed Integer Non Linear Problem using a cross-interference mat...
