An in-depth study of harmonic current reduction in European commercial buildings due to the cancellation effect when a set single-phase uncontrolled rectifiers and fluorescent lamps are connected at same voltage level is essential, since both types non-linear loads very present residential sectors. This paper provides an appropriate index assess global currents for this study. The equivalent ci...

Given increases in electricity consumptions, coupled with finite resources and technological advances, ICT-enabled electrical networks such as smart grids are increasingly being deployed by energy companies. One part of smart grids is smart meters, which are digital electrical meters, having the potential to increase energy efficiency in both residential and industrial sectors. However, a chall...

Given rising electricity consumption, coupled with finite resources, ICT-enabled electrical networks such as smart grids are increasingly being deployed by energy companies. One part of smart grids is smart meter technology (SMT), which are digital electrical meters, having the potential to increase energy efficiency in both residential and industrial sectors. However, a challenge to SMT-implem...

With a rapid growth rate, urbanization is casting a profound impact on both production and residential sector in China, influencing the energy consumption accordingly. Based on theoretical analysis and LMDI (Log Mean Divisia Index) method, the change of energy consumption in the two sectors is decomposed into several effects related to urbanization. According to the empirical result from 1980 t...

Traditional whole building energy modeling suffers from several factors, including the large number of inputs required to characterize the building, the specificity required to accurately model building materials and components, simplifying assumptions made by underlying simulation algorithms, and the gap between the as-designed and as-built building. Prior work has attempted to mitigate these ...

We describe a practical method for estimating the economic cost of outages in electronic communications networks, accommodating temporal, geographical and sectoral variations in incidence. The method is illustrated with two types of examples: a hypothetical outage of the main fixed line network operator in Ireland, and seven examples of outages affecting individual local exchanges in areas with...

An inventory of anthropogenic primary aerosol emissions in China was developed for 1990–2005 using a technology-based approach. Taking into account changes in the technology penetration within industry sectors and improvements in emission controls driven by stricter emission standards, a dynamic methodology was derived and implemented to estimate inter-annual emission factors. Emission factors ...

Airborne particulate trace metals have been measured bimonthly during day and night hours in four permanent stations located in residential, industrial and commercial sectors of La Plata City region, to characterize the sources and variability of atmospheric inputs. Airborne trace metal regional averages (Pb 64 +/- 62, Cu 30 +/- 27, Mn 26 +/- 20, Zn 273 +/- 227, Fe 1183 +/- 838, Ca 5343 +/- 361...

In the recent years, there has been an increasing academic and industrial interest for analyzing the electrical consumption of commercial buildings. Whilst having similarities with the Non Intrusive Load Monitoring (NILM) tasks for residential buildings, the nature of the signals that are collected from large commercial buildings introduces additional difficulties to the NILM research causing e...

This study investigates how neighborhood deterioration is associated with stress and depressive symptoms and the mediating effects of perceived neighborhood social conditions. Data come from a community survey of 801 respondents geocoded and linked to a systematic on-site assessment of the physical characteristics of nearly all residential and commercial structures around respondents' homes. St...
