Research ArticleOpen accessIn the abstractAn Investigation of Sustainable Development in Urban Neighborhoods Using Statistical ModelsSedigheh LotfiProblem statement: Sustainable has a close relation to the quality of life in the different parts of each city. While the level of sustainability is studied in many urban areas world wide but it has been less considered in the Iranian cities. The city of Babolsar is selected to investigate the level of development by detail study of its 16 … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,337 accessesView PDFCite
Research ArticleOpen accessIn the abstractRoad Transport Congestion Costs Calculations Adaptation to Engineering ApproachMarjan Lep, Beno MesarecThe article represents so called "engineering" approach for computing the total road transport congestion costs. According to economic welfare theory, the total costs of transport congestion are defined as dead weight loss (DWL) of infrastructure use. With a set of equations DWL could be formulated in a mathematical way. Because such form of equation is not directly applicable for concrete … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Indoor Positioning System (IPS) using Grid ModelWutjanun Muttitanon, Nitin Kumar Tripathi, Marc SourisTo date many positioning systems are available to determine or track a user's location; three main categories include Global Positioning System (GPS), wide area location system and indoor positioning system. GPS has its limitation (poor signals) in indoor or urban uses, while wide-area location systems are cellular networks dependent. For indoor positioning system many approaches like infrared sensing, radio frequency, … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 7,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping of Flood Risk Zones in Ala River Basin Akure, NigeriaOlajire Olabanji Olatona, O.A. Obiora-Okeke, J.R. AdewumiFloods are water induced disasters that lead to temporary inundation of dry land and cause serious damages in the affected location such as loss of lives and properties and destruction of infrastructures. Nigeria has experienced a lot of flood incidences and the impact of flood has also increased due to population growth coupled with uncontrolled developmental practices. The result of … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 7 Feb 2018 · 9,243 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensity Based Routing Algorithm for Spare/Dense Topologies in Wireless Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: A Mobile Ad-Hoc Networks (MANETs) operate in environments without infrastructures with an undefined network size. Most routing protocols of Mobile Ad-hoc Networks (MANETs) were studied using open space models where nodes were able to move throughput the entire simulation area. However, a more realistic topology should account for restricted mobility of nodes, such as in an urban city … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Integration of Network-Based Models for Spill Response and Homeland SecurityDavid E. Amstutz, Rakesh Bahadur, Jonathan M. Pickus et al.The integration of three hydraulic GIS (Geographic Information System) applications is presented which represent the water infrastructures of cities and urban areas and US streams and rivers. The water infrastructures include drinking water distribution systems, wastewater collection systems and source water. The National Research Council[1] states that problems dealing with the collective behavior of networks such as river systems, water … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,729 accessesView PDFCite
