ESTIMATING OPERATIONAL COSTS FOR ENHANCED CONTINUITY IN WATER SUPPLY AND SANITATION SERVICES: AN INVERSE DATA ENVELOPMENT ANALYSIS APPROACH IN CHILEAN UTILITIES

Study region: The largest 23 water utilities in Chile providing water and sanitation services to 97.9 % of total urban customers.Study focus: This study introduces an innovative methodological framework based on inverse data envelopment analysis technique to quantify the additional operational costs required for water utilities to enhance hp 15-da0

The present work investigates the effect of precursor concentration (mc) on the structural, optical, morphological and electrical conductivity properties of In2S3 thin films grown on amorphous glass substrates by nebulized spray pyrolysis (NSP) technique.The mixed phase of cubic and tetragonal structure of In2S3 thin films at higher concentration h

The keychron m6 mouse time evolution of the photoluminescence (PL) of 1300-nm emitting InGaAsN/ GaAs/GaAsP strain-compensated single quantum well (QW) in the temperature range of T 1/4 10 K - 300 K is investigated.The PL spectra observed at the early stages of copyright recombination is dominated by two transitions.These two transitions are identif
