Urban regeneration has proved to be a testing and on-going challenge for both central government and local authorities within the UK and successful solutions have proved to be elusive, at best partial rather than comprehensive and often difficult to sustain. Long-term structural economic decline, the continuing shift from a manufacturing to a service and knowledge based economy, the relentless ...

As urban population grow, commercial activities play a fundamental role in providing goods, services and are part of cities fabric. Policy makers and urban planners need new tools to study these areas. This paper describes how machine learning can be applied to predict the density of commercial activities in cities. A supervised machine learning method called Gradient Boosting was applied to a ...

here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

Since the industrial revolution, accelerated urban growth has overflown administrative divisions, merged cities into large built extensions, and blurred the boundaries between urban and rural land-uses. These traits, present in most of contemporary metropolis, complicate the definition of cities, a crucial issue considering that objective and comparable metrics are the basic inputs needed for t...

Urban vulnerability is the probability of damage to cities and urban infrastructures against natural unnatural events. In this regard, in last half century, land subsidence has involved many countries as a potential risk for urban, industrial agricultural areas. With occurrence subsidence, physical structural characteristics structures built city are changed show different behavior. For reason,...

After 1980s, the People’s Republic of China modernized rapidly, resulting in vast changes to the fabric of cities. At the same time, China developed more sophisticated urban planning practices and historic preservation regulation. In 1982, the government officially created the concept of “predominant historic and cultural city,” for cities that are considered to have very significant historic a...

in this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. fabrics are impregnated with shear thickening fluid (stf). the effects of the (stf) have been considered as frictional effect. the stf has been made (nano silica and polyethylene glycol (peg)) and then diluted by ethanol proportion of 3:1. yarn pulling out test from in...

For many years the urban renewal approach of Rotterdam, executed during the period 19751993, served as an example on the national and international level. With this approach a process of revitalization was initiated, which meant that the urban fabric and building supply had to adapt to changing conditions and accommodate new demands. Due to large financial and social investments in Rotterdam, a...
