Implementation of smart grid provides an opportunity for concurrent implementation of nonintrusive appliance load monitoring (NIALM), which disaggregates the total household electricity data into data on individual appliances. This paper introduces a new disaggregation algorithm for NIALM based on a modified Viterbi algorithm. This modification takes… (More)

A two-stage computational model of evolution of a plume generated by laser ablation of an organic solid is proposed and developed. The first stage of the laser ablation, which involves laser coupling to the target and ejection of molecules and clusters, is described by the molecular dynamics ͑MD͒ method. The second stage of a long-term expansion of the… (More)
We consider the problem of overlap in the power draw between different appliances in nonintrusive load monitoring. We complement the power features by time-on and time-off statistics and use approximate semi-Markov models for robust computationally-efficient disaggregation. The superior disaggregation accuracy of our algorithm is demonstrated on actual… (More)
A computational approach that combines the molecular dynamics (MD) breathing sphere model for simulation of the initial stage of laser ablation and the direct simulation Monte Carlo (DSMC) method for simulation of the multi-component ablation plume development on the time-and length-scales of real experimental configurations is presented. The combined… (More)
