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 studies the uniqueness of two non-integral finite ordered meromorphic functions with finitely many poles when they share sets. Also, it provides an answer to a question posed by Gross for particular class functions. Moreover, some observations are made on results due Sahoo and Karmakar, Acta Univ. Sapient. Math., doi:10.2478/ausm-2018-0025; Sarkar, Bol. Soc. Mat. Mex., doi:10.1007/s4...

This article discusses solving non-linear programming problems containing integer, discrete and continuous variables. A novel mixed integer-discrete-continuous, non-linear optimization method based on Differential Evolution algorithm is described. Also the required handling techniques for integer, discrete and continuous variables are described including the techniques needed to handle boundary...

The facility location problem is a strategic decision-making for a supply chain, which determines the profitability and sustainability of its components. This paper deals with a scenario where two supply chains, consisting of a producer, a number of distribution centers and several retailers provided with similar products, compete to maintain their market shares by opening new distribution cent...

Multiplication of two numbers represented in base is shown to be computable by an on-line algorithm when is a negative integer, a positive non-integer real number, or a complex number of the form , where is a positive integer.

‎Let $G$ be a finite group‎. ‎We say that the derived covering number of $G$ is finite if and only if there exists a positive integer $n$ such that $C^n=G'$ for all non-central conjugacy classes $C$ of $G$‎. ‎In this paper we characterize solvable groups $G$ in which the derived covering number is finite‎.‎
