This paper presents a possibilistic (fuzzy) model in optimal siting and sizing of Distributed Generation (DG) for loss reduction and improve voltage profile in power distribution system. Multi-objective problem is developed in two phases. In the first one, the set of non-dominated planning solutions is obtained (with respect to the objective functions of fuzzy economic cost, and exposure) using...

The scientific community is active in developing new models and methods to help reach the ambitious target set by UN SDGs7: universal access electricity 2030. Efficient planning of distribution networks a complex multivariate task, which usually split into multiple subproblems reduce number variables. present work addresses problem optimal secondary substation siting, means different clustering...

Previous research suggests that minority residential areas have a disproportionate likelihood of hosting various envirotnmental hazards. Some critics have responded that the contemporary correlation of race and hazards may reflect post-siting minority movein, perhaps because of a risk effect on housing costs, rather than discrimination in siting. This article examines the disproportionate sitin...

safety distance has already been a main measurement for the hazard control of chemical installations interpreted to mean providing space between the hazardous installation and different types of targets. but, the problem is how to determine the enough space. this study considers the application of quantitative risk assessment to evaluating a compressed natural gas station site and to identify n...

Centre of the Cell is a unique biomedical science education centre, a widening participation and outreach project in London's East End. This article describes Centre of the Cell's first five years of operation, the evolution of the project in response to audience demand, and the impact of siting a major public engagement project within a research laboratory.

Background There is a growing concern that school siting, construction and renovation practices in the United States are inconsistent with efforts to reduce sprawl, encourage compact growth, and increase the sustainability of our built and natural environments. Current practices also undermine efforts to support walking and cycling to school, and to strengthen community-based schools. A range o...

BACKGROUND Pit latrines are one of the most common human excreta disposal systems in low-income countries, and their use is on the rise as countries aim to meet the sanitation-related target of the Millennium Development Goals. There is concern, however, that discharges of chemical and microbial contaminants from pit latrines to groundwater may negatively affect human health. OBJECTIVES Our g...
