Bus rapid transit is an innovative, high capacity, lower cost public transit solution in metropolitan cities. Idea is to dedicate lanes for quick and efficient transport of passengers to their destinations. In the present investigation the environmental impact assessment of bus rapid transit in Tehran metropolitan city is brought out. For this purpose bus rapid transit Lane No. 10 is investiga...
Investment in transport infrastructure reduces the cost of distance and enables firms to establish contacts over larger distances. Using data from a panel of Spanish manufacturing firms and geographic information system techniques, this article studies the impact of domestic transport cost reductions on firms’ export market participation, taking into account the role of entry costs and other fi...

Wan Carbon capture and sequestration (CCS) is an important option for CO2 mitigation and an optimized CO2 pipeline transport system is necessary for large scale CCS implementation. In the present work, a hydrodynamic ...
the problem of designing a set of routes with minimum cost to serve a collection of customers with a fleet of vehicles is a fundamental challenge when the number of customers to be dropped or picked up is not known during the planning horizon. the purpose of this paper is to develop a vehicle routing problem (vrp) model that addresses stochastic simultaneous pickup and delivery in the urban pub...
the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
Optimal transport distances are a fundamental family of distances for probability measures and histograms of features. Despite their appealing theoretical properties, excellent performance in retrieval tasks and intuitive formulation, their computation involves the resolution of a linear program whose cost can quickly become prohibitive whenever the size of the support of these measures or the ...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
In this work, a molecular dynamics simulation of the transport of water - methanol mixture through the single wall carbon nanotube (SWCNT) is reported. Methanol and water are selected as fluid molecules since water represents a strongly polar molecule while methanol is as an intermediate between polar and strongly polar molecules. Some physical properties of the methanol-water mixture such as r...
Transportation is a necessity if the day-to-day economic activities of the society must move on. There are different modes of informal transport available in Nigeria. This study evaluated the determinants of the modal choice of informal transport among commuters in North central city of Ilorin, Nigeria. The study used primary data generated through a structured questionnaire administered to 100...
Western region development is fundamental to the sustainable growth of China. The rapid growth in the East and the backwardness in the West vividly demonstrate its unbalanced regional economic structure. The catching-up of the Western region constitutes a major concern for the long-term sustainable development in terms of economic growth as well as in terms of politic stability. Western region ...
