Over recent decades, "Transit-oriented development" has been developed as a new approach based on sustainability concepts. This approach is mainly concerning coordinated action between land use planning and transportation planning which tries to create a clean, people friendly, livable, and dynamic community with growing local economy. Today, old urban centers face enormous challenges in terms ...

developing an integrated model, establishing a balance between conservation and revitalization objectives in the historic environment, has always been a controversial issue in many countries; however, they sometimes have a type of symbiotic relationship with each other. in this regard, the main aim of this paper is to answer this question: is it possible to provide an appropriate model for “int...

extended abstract 1. introduction today the irregular growth of the population and its illogical distribution across natural and cultural environments of different communities has necessitated sustainable development in response to the unstable conditions of cities. mashhad is a city with fast growth and development but with no clear plan, especially after land reform program. in this sense, th...

We establish existence and non-existence results for entire solutions to the fractional Allen-Cahn equation in R, which vanish on helicoids and are invariant under screw-motion. In addition, we prove that helicoids are surfaces with vanishing nonlocal mean curvature.

We study the effect of a higher-order nonlinearity in the standard Kuramoto-Sivashinsky equation: partial differentialxG(Hx). We find that the stability of steady states depends on dv/dq , the derivative of the interface velocity on the wave vector q of the steady state. If the standard nonlinearity vanishes, coarsening is possible, in principle, only if G is an odd function of Hx. In this case...
