Pollution in P2P file sharing occurs when a large number of decoy files are injected into the P2P system. Since peers “serve” each other in the P2P file sharing system, it is obvious that pollution dynamics are closely related to user behavior. Therefore, we first conduct a human subject study to investigate user behavior. We identify the factors that are key to model user behavior, e.g., coope...
BACKGROUND: Traffic-related pollution is associated with asthma onset in children. Its effect on adult-onset asthma is poorly investigated. OBJECTIVE: We used the SAPALDIA cohort study to investigate associations between the 11year change (1991-2002) in home outdoor traffic-related particulate matter up to 10 micrometers in diameter (TPM10) and asthma incidence. METHODS: Never-smokers without a...
Traffic noise pollution is a serious threat to wildlife species, resulting in isolating and reducing the population. The Asian Highway of Tehran-Mashhad, from which a 26.51 km long part is located inside Golestan National Park, is the main source of noise disturbance inside the area. The purpose of this study was to determine the most important criteria for noise pollution of this road; in orde...
Introduction: The body's response to noise pollution is very similar to the way the body responds to stress, which can lead to poor health over time. In this regard, this study was conducted to determine the general health of the elderly and its relationship with traffic noise pollution in Ardakan. Methods: This descriptive cross-sectional study was conducted in 1399. Participants were 200...
A neuro-fuzzy approach to vehicular traffic flow prediction for a metropolis in a developing country
Short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. The strong need to monitor and control congestion time and costs for metropolis in developing countries has therefore motivated the current study. This paper establishes the applicatio...
Background and Aim: Motor vehicles are an absolute necessity used extensively in all countries of the world. They are a major cause of air pollution with highly undesirable consequences. Thus, exposure to traffic pollution is a growing public health concern. Several studies indicate that people in the cabin of a vehicle inhale air with high concentrations of pollutants such as nitrogen oxides...
conclusions proximity to road traffic might be a risk factor for ra as there are suspected effects associated with no2 and so2. overall, the available evidence is too preliminary and scarce to draw firm conclusions. however, the results indicate the feasibility of further studies elucidating on the relationship between air pollution and ra. results four relevant papers were included in a qualit...
In the Macao Peninsula, the high population density (49,763 inhabitants/km2) and the lack of control over the number of vehicles (460 vehicles/km) have led to an increase in urban pollution. To provide useful information to local government and urban planners, this paper investigates the spatial distribution of traffic noise in the Macao Peninsula. The interactions among urban form, traffic flo...
Few studies have addressed associations between traffic-related air pollution and respiratory disease in young children. The present authors assessed the development of asthmatic/allergic symptoms and respiratory infections during the first 4 yrs of life in a birth cohort study (n = approximately 4,000). Outdoor concentrations of traffic-related air pollutants (nitrogen dioxide PM(2.5), particl...
