The urban heat island effect is linked to the built environment and threatens human health during extreme heat events. In this study, we analyzed whether characteristic land uses within an urban area are associated with higher or lower surface temperatures, and whether concentrations of ―hot‖ land uses exacerbate this relationship. Zonal statistics on a thermal remote sensing image for the City...

Decentralized municipal stormwater management, whereby best management practices are dispersed throughout a watershed, are gaining popularity but face unique constraints related to land access and citizen engagement. Decentralized installations require perpetual access to public and private land, a constraint that may be solved creatively in many urban settings through the repurposing of vacant...

This study assesses whether multifunctional edible landscaping business models provide a sufficient business case at enterprise and city scales to justify widespread implementation. First, semi-structured interviews were conducted with four landscaping entrepreneurs, and the information obtained from the interviews was utilized to carry out a business model comparison with the Business Model Ca...

Abstract The aim of the present study was to establish effect management type and environmental variables on structure, abundance species richness soil mites (Acari: Mesostigmata) in twelve urban green areas Bucharest-Romania. Three categories ecosystem based upon were investigated: protected area, managed (metropolitan, municipal district parks) unmanaged areas. which analysed were: air temper...

Nearly 8 million dry tons (7 256 000 t) of municipal sewage sludge are produced each year in the USA by the more than 15 000 publicly owned treatment plants and the tonnage is increasing. Municipalities are faced with increasing cost of incineration, decreasing land for and increasing costs of landfills, and environmental concerns over ocean dumping. Under the circumstances, the attractiveness ...

It has been observed empirically that each coe cient in a Parks-McClellan lter converges to a steady state value as the lter length increases. This suggests the possibility of obtaining lters that are near optimal while "re-using" lter coe cients from shorter lters in the design of longer lters. In the context of approximate processing this then allows a ltering operation to be done in stages. ...

The science parks have important role in development of technology and are able to make economic growth of the countries. The purpose of this paper is the presentation of a Fuzzy Expert System (FIS) as Intelligent Systems to evaluate the science and technology parks.
