There is evidence that access to green spaces have positive effects on health, possibly through beneficial effects on exercise, air quality, urban heat islands, and stress. Few previous studies have examined the associations between green space and mortality, and they have given inconsistent results. This ecological study relates green space to mortality in Hong Kong from 2006 to 2011. The Norm...
To mitigate the urban heat island effect has become a global issue when we are faced with the challenge of climate change. Through literature review, plant photosynthesis can reduce the carbon dioxide and mitigate the urban heat island effect to a degree. Because there are not enough open space and parks, green roof has become an important policy in Taiwan. We selected elementary school buildin...
Mobility restrictions imposed during the COVID-19 pandemic present a useful study system for understanding temporal and spatial patterns of green space use. Here, we examine characteristics sociodemographic factors associated with change in frequency use before lockdown Brisbane, Australia drawing on survey 372 individuals. Applying regression analysis, found that individuals who visited differ...
In this paper we investigate a kind of boundary value problem involving a fractional differential equation. We study the existence of positive solutions of the problem that fractional derivative is the Reimann-Liouville fractional derivative. At first the green function is computed then it is proved that the green function is positive. We present necessary and sufficient conditions for existen...
This paper addresses a challenging global problem, insufficient accessible urban public green space, based on building typology. Offering sufficient spaces and maintaining the equalities of citizens’ accessibility in high-intensity cities has been increasingly challenging. Thus, providing adequate by 2030 is sub-goal SDGs No. 11. Solving this problem commonly considered responsibility planning;...
Extended Abstract Introduction Urban green space, including major applications and major cities considered that it comes as breathing lungs of cities is mentioned. Since urban space filled with smoke, tail, noise machines, factories, and motorized equipment is urban green spaces urban places that people only hours away from family and friends along with rest and pay a stylized. Due to ur...
The fundamental solution (Green function) for the Cauchy problem of the space-time fractional diffusion equation is investigated with respect to its scaling and similarity properties, starting from its Fourier-Laplace representation. Then, by using the Mellin transform, a general representation of the Green function in terms of Mellin-Barnes integrals in the complex plane is derived. This allow...
