The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

While more attention has been paid in recent years to urban point source pollution control through the establishment of wastewater treatment plants in many developing countries, no considerable planning nor any serious measures have been taken to control urban non-point source pollution (urban stormwater runoff). The present study is a screening analysis to investigate the pollution loads in ur...

this paper reviews the experience of persian designers and planners for creating the most livableand greenery capital city in the hole region of middle east throughout the 17th century. new concepts of urban greendevelopment emerged in that time. some of these ideas where extremely creative and vanguard from there era andstill some of them are the main theoretical basics of urban green planning...

Measurements of height and weight are important data source relating to growth and development, puberty, and nutritional status of children and adolescents. In clinical setting, the charts of the National Center for Health Statistics (NCHS), USA, are used in Iran. A survey identified significant differences in weight- and height-for-age across provinces, between urban and rural children. Althou...

Urban population potential is a good measure of urban spatial interactions. However, previous studies often assigned population data to the administrative point of the government or the centroid of the region, such as the county, ward or village. In these cases, two problems exist: (1) the zone centroid problem and (2) the scale problem. To better deal with these problems, we proposed a novel m...

Abstract. Appropriate spatial accessibility to healthcare facilities is an important component of the efficient delivery healthcare. This study aims measure in Isfahan Metropolitan Area, a rapidly growing megacity Iran. We used two methods population-weighted fuzzy analytic hierarchy process and two-step floating catchment area (2SFCA) urban facilities, including hospitals, pharmacies, clinics,...

INTRODUCTION TRANSPORTATION of people is increasing as our society grows and the demand for railway services that can provide high-speed and high-capacity transportation is becoming greater. The number of train rides taken in Japan in 2006 was 22,243 million, more than anywhere else in the world by some margin, making Japan one of the world’s leading railway nations. A major feature of railway ...

Progress of construction technology Japan has a relatively small proportion of lowland, consisting mainly of alluvial coastal plains. Railway construction started in the early Meiji Era (1868–1912) and since the construction technology was still immature, the first lines were built in level coastal areas. The rails were laid mostly on earth structures such as embankments and cuttings. Many rail...

Urban railway systems are increasingly relying on information and communications technologies (ICT). This evolution makes cybersecurity an important concern, in addition to the traditional focus on reliability, availability, maintainability and safety. In this paper, we examine two examples of cyberintensive systems in urban railway environments—a communications-based train control system, and ...

This contribution analyses the urban identity and historical patterns of spatial development in ancient Baghdad Isfahan, according to Actor Network Theory (ANT) Actor-Relational Approach (ARA). In case two different hubs (Baghdad Isfahan).This article demonstrates how course history, those interactions between various path-dependent networks have produced various, but specific types urbanity th...
