Traffic congestion worldwide has led to loss of human lives due to failure in transporting accident victims, critical patients, medical equipment and medicines on time. With the unending growth in vehicular traffic everywhere, Internet of Things (IOT) and Vehicular Ad Hoc Network (VANET) have embarked as a promising platform for an Intelligent Traffic Management System (ITMS). Many researches h...

A data-driven realistic design and evaluation of vehicular mobility has been particularly challenging due to a lack of large-scale real-world measurements in the research community. Current research methodologies rely on artificial scenarios, random connectivity, and use small and biased samples. In this paper, we perform a combined study to learn the structure and connectivity of urban streets...

Vulnerability assessment has become an important element for wise resource management and land use planning. This work examined the sensitivity of karstic aquifers, in the area of Irbid governorate northwest Jordan, to surface contamination by applying the EPIK method, and then compared this susceptibility evaluation to water-chemistry data collected from wells and springs within the area. An a...

BACKGROUND Vehicular traffic is a major source of outdoor air pollution in urban areas, and studies have shown that air pollution is worse during hours of commuting to and from work and school. However, it is unclear to what extent different commuting behaviors are a source of air pollution compared to non-commuters, and if air pollution exposure actually differs by the mode of commuting. This ...

The effect of automobile pollution was determined on chlorophyll content of four different tree species viz. Azadirachta indica L., Conocarpus erectus L., Guiacum officinale L.and Eucalyptus sp. growing along the roads of the city.  Significant changes in the level of chlorophyll “a”, chlorophyll “b” and total chlorophyll “a+b” were found in the leaves of fou...

UNLABELLED : Air pollution has been a matter of great concern globally because of the associated health risks to individuals. The situation is getting worse in developing countries with more urbanization, industrialization and more importantly the rapidly growing population posing a threat to human life in the form of pulmonary, cardiovascular, carcinogenic or asthmatic diseases by accumulating...

T HE LAST TWO decades have witnessed unprecedented growth in telecommunications, particularly in the area of wireless communications. This development in telecommunications opens doors to many sophisticated complex systems, e.g., social networks, smart grids, vehicular networks, and sensor networks, which previously were not feasible. Graph theory is among the most widely used tools for modelin...

In this work we propose an UML modeling of the “Greedy Perimeter Stateless Routing” (GPSR) protocol that integrate this geographic routing protocol, into "JavaNetwork Simulator" to simulate and study this protocol in a first time and offer some improvement in these features. Java Network Simulator (JNS) is a project of "translation" of Network Simulator (NS) in Java initiated by "the UCL Depart...

BACKGROUND Air pollution from vehicular traffic has been associated with respiratory diseases. In Palermo, the largest metropolitan area in Sicily, urban air pollution is mainly addressed to traffic-related pollution because of lack of industrial settlements, and the presence of a temperate climate that contribute to the limited use of domestic heating plants. This study aimed to investigate th...

AnnAGNPS (Annualized AGricultural Non-point Source), a continuous simulation and distributed pollution model, is widely applied in evaluating non-point source pollution and watershed management practices. However, the complexity of required input data and modeling procedure keep it from being an efficient modeling tool. An integrated GIS interface was developed to facilitate organizing and prep...
