Transport Phenomena in the Urban Street Canyon
1 Abstract A generic proecological traffic control model for the urban street canyon is proposed by development of advanced continuum field hydrodynamical control model of the street canyon. The model of optimal control of street canyon dynamics is also investigated. The mathematical physics' approach (Eulerian approach) to vehicular movement, to pollutants' emission, and to pollutants' dynamic...
متن کاملExposure and Toxicity Assessment of Ultrafine Particles from Nearby Traffic in Urban Air in Seoul, Korea
OBJECTIVES We investigated the particle mass size distribution and chemical properties of air pollution particulate matter (PM) in the urban area and its capacity to induce cytotoxicity in human bronchial epithelial (BEAS-2B) cells. METHODS To characterize the mass size distributions and chemical concentrations associated with urban PM, PM samples were collected by a 10-stage Micro-Orifice Un...
متن کاملPseudo - simultaneous measurements for the vertical variation of coarse , fine and ultrafine 2 particles in an urban street canyon 3 Authors 4
Pseudo–simultaneous measurements for vertical variation of coarse, fine and ultra fine particles in an urban street canyon. Atmospheric Environment 42, 4304–4319. Abstract 1 The vertical variation of particle number distributions and concentrations in a street 2 canyon is the result of the competing influences of meteorology, traffic and transformation 3 processes overall and for various partic...
متن کاملComputer Vision Techniques for Background Modelling in Urban Traffic Monitoring
Traffic data collection is an essential issue for road-traffic control departments, which need real-time information for traffic-parameter estimation: road-traffic intensity, lane occupancy, congestion level, estimation of journey times, etc., as well as for early incident detection. This information can be used to improve road safety as well as to make an optimal use of the existing infrastruc...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
