We derive a formula connecting in any dimension the Green function on the D+1 dimensional Euclidean Rindler space and the one for a minimally coupled scalar field with a mass m in the D dimensional hyperbolic space. The relation takes a simple form in the momentum space where the Green functions are equal at the momenta (p0,p) for Rindler and (m, p̂) for hyperbolic space with a simple additive r...

Urban parks, forests and open space systems provide many amenities for city dwellers. Yet perceptions of public value may not incorporate all of the scientifically confirmed public goods and services of urban green space. Theory and methods of economic valuation have been used to derive green space values – including direct use, environmental services, hedonic pricing and human health estimatio...

This study, on inner area in Ashiya city, by means of GIS, aims to make it clear how much trees space diminished by the Hanshin earthquake disaster, and to simulate green space system under the assumpution of animals moving. As a result, that diminished 6.12% of trees space in the private lots. We can predict effectively the betterment of green space system,through getting massive green space u...

Accurately quantifying the variation of urban green space is the prerequisite for fully understanding its ecosystem services. However, knowledge about the spatiotemporal dynamics of urban green space is still insufficient due to multiple challenges that remain in mapping green spaces within heterogeneous urban environments. This paper uses the city of Hangzhou to demonstrate an analysis methodo...

Green space has been identified as a modifiable feature of the urban environment and associations with physiological and psychological health have been reported at the local level. This study aims to assess whether these associations between health and green space are transferable to a larger scale, with English cities as the unit of analysis. We used an ecological, cross-sectional study design...

Water supply of green spaces in arid areas is a major challenge. A high percentage of green spacescreate lawns, which are high water consumer landscapes. Due to the environmental, recreational andathletic values of lawns, they are considered as non-removable elements in urban green space development.This paper reviews and discusses strategies for efficient water usage in lawn areas using librar...

The Barcelona superblock is an urban neighbourhood transformation strategy, with which car-based traffic redirected away from streets that are inside a 3 × block configuration. This design concept promises opportunities for alternative street use such as the of space into green space. potential to foster due however unclear, particularly outside original Barcelonan context. Concerning densifica...
