Compacted soil has lower water infiltration and hydraulic conductivity, which contributes to increased runoff and erosion on slopes. The aim of the present study was to assess runoff and sediment on three skidding trail longitudinal gradients (15%, 25%, and 35%) and different levels of machine traffic (low, medium, and high), over a two-year period following the impact in the Hyrcanian forest, ...
اندازه گیری شدت صدا (sound intensity) برای تشخیص منابع نویز در یک مجموعه متراکم از قطعات در حال کار و مرتبط با یکدیگر در خودرو کابردهای فراوانی دارد. خوشبختانه بر اساس تلاشهای محققان [ j.y.chunf] and [f. j. fahy] سیستمی طراحی شده که میتوان بدون استفاده از اتاقک آکوستیک شدت صوت را با دقت خوبی در محیط های آزاد اندازه گیری کرد.
Traffic management solutions are increasingly called for to address problems of transport and mobility. In particular, coordinated traffic lights that create green waves along major arterials are an increasingly used strategy to reduce travel times. Although it is usually assumed that an improved traffic flow will result in lower vehicle emissions, little scientific research has been spent on t...
BACKGROUND In epidemiological studies of the potential health effects of traffic related air pollution, self reported traffic intensity is a commonly used, but rarely validated, exposure variable. METHODS As part of a study on the impact of Traffic Related Air Pollution on Childhood Asthma (TRAPCA), data from 2633 and 673 infants from the Dutch and the German-Munich cohorts, respectively, wer...
BACKGROUND Epidemiological evidence of the effects of long-term exposure to air pollution on the chronic processes of atherogenesis is limited. OBJECTIVE We investigated the association of long-term exposure to traffic-related air pollution with subclinical atherosclerosis, measured by carotid intima media thickness (IMT) and ankle-brachial index (ABI). METHODS We performed a cross-sectiona...
In this work, an intelligent traffic light controller that incorporates very important personnel (VIP) movement is presented. VIP movement often cause chaos or in the worst case accident at cross junctions. Traffic quantity, waiting time and siren intensity are the inputs to the system. The fuzzy logic tool box in Matlab 7.0 was used to simulate the system. The results obtained from running the...
Mobility, and the fact that nodes may change their communication peers in time, generate permanently changing traffic flows in a Bluetooth scatternet. Thus, forming an optimal scatternet for a given traffic pattern may be not enough, rather a scatternet that best supports traffic flows as they vary in time is required. In this article we propose an algorithm suite that enables us to modify the ...
Received Jan 12, 2018 Revised Mar 16, 2018 Accepted Mar 30, 2018 Traffic congestion plagues all driver around the world. To solve this problem computer vision can be used as a tool to develop alternative routes and eliminate traffic congestions. In the current generation with increasing number of cameras on the streets and lower cost for Internet of Things (IoT) this solution will have a greate...
In this article, we study transportation network in Minnesota. We show that the system is characterized by Taylor’s power law for fluctuation scaling with nontrivial values of the scaling exponent. We also show that the characteristic exponent does not unequivocally characterize a given road network, as it may differ within the same network if one takes into account location of observation poin...
