Genetic algorithms (GAs) emulate the process of biological evolution, in a computational setting, in order to generate good solutions to difficult search and optimisation problems. GA-based optimisers tend to be extremely robust and versatile compared to most traditional techniques used to solve optimisation problems. This paper provides a very brief introduction to GAs and outlines their utili...

The privacy of electricity consumers has become one the most critical subjects in designing smart meters and their proliferation. In this work, a multilayer architecture been proposed for anonymous data collection from meters, which provides: (1) anonymity information third-party consumers; (2) Secure communication to utility provider network billing purposes; (3) Online control sharing end-use...

background & purpose: in the health sector, in addition to the important consequence of treatment, health system should meet the expectations regarding the desirability of services. expectations and perceptions of patients about the desirability of services play an important role in selecting hospitals, their loyalty to the organization & replanning to purchase. thus the present study has been ...

As expectations have risen about the deployment of smart grids, it is important to investigate the diffusion process of smart equipment such as smart meters, photovoltaic generation, and electric/hybrid vehicles. However, since the revealed preference data have not been accumulated for smart equipment diffusion, this paper conducts a conjoint analysis to examine consumers’ stated preferences on...

A quantity of miscible contaminant gas is released into the atmospheric boundary layer and the objective is to describe the evolution of contaminant concentration values within the cloud. Although turbulent convective motions will spread the contaminant cloud over distances of tens of meters the only mixing between host and contaminant fluid, and hence reduction of concentration values, takes p...

Abstract Free-standing hybrid risers are vertical slender steel pipes that commonly used in the oil and gas industry. These structures subjected to complex hydrodynamic loads results fatigue damage. The tidal forces develop on Freestanding Risers (FSR) with buoyancy cans ( BC ) because of varying outer pipe dimensions investigated this work. study considered riser diameters 0.2, 0.3, 0.5 0.6 me...
