The poet and philosopher, George Santayana is often quoted as having said that “those who cannot learn from history are doomed to repeat it.” While he certainly did not have emissions forecasting in mind when identifying this conceit, it does have application to air pollutant emission projection practitioners. Under contract to the Lake Michigan Directors Consortium, E.H. Pechan & Associates, I...

The day-ahead electricity market is closely related to other commodity markets such as the fuel and emission markets and is increasingly playing a significant role in human life. Thus, in the electricity markets, accurate electricity price forecasting plays significant role for power producers and consumers. Although many studies developing and proposing highly accurate forecasting models exist...

In order to perform a study of the carcinogenic potential of polycyclic aromatic hydrocarbons (PAH), benzo(a)pyrene equivalent (BaP-eq) concentration was calculated and modelled by a receptor model based on positive matrix factorization (PMF). Nineteen PAH associated to airborne PM10 of Zaragoza, Spain, were quantified during the sampling period 2001-2009 and used as potential variables by the ...

To help systematically lower anthropogenic Greenhouse gas (GHG) emissions, accurate and precise GHG emission prediction models have become a key focus of climate research. The appeal is that the predictive will inform policymakers, hopefully, in turn, they bring about systematic changes. Since transportation sector constantly among top contributors, especially populated urban areas, substantial...

In a vehicular ad hoc network (VANET), the periodic exchange of single-hop status information broadcasts (beacon frames) produces channel loading, which causes channel congestion and induces information conflict problems. To guarantee fairness in beacon transmissions from each node and maximum network connectivity, adjustment of the beacon transmission power is an effective method for reducing ...

Detailed on-line measurements of city air quality are necessary to support compliance with air quality standards and emission strategy developments and to inform both policy makers and the general public in a timely manner. Current approaches to pollution monitoring, however, rely on very small numbers of stationary nodes. Providing detailed air quality information is a particularly hard challe...

This study identified concentrations, molecular distributions, toxicities, and sources of polycylic aromatic hydrocarbons (PAHs) in road dust from different areas of Ulsan, the largest industrial city in Korea. The total PAH concentrations in industrial areas were dependent on industrial emissions and vehicular exhaust, while those in urban areas were mainly dependent on traffic density, sampli...

A general proecological urban road traffic control idea for the street canyon is proposed with emphasis placed on development of advanced continuum field gasdynamical (hydrodynamical) control model of the street canyon. The continuum field model of optimal control of street canyon is studied. The mathematical physics' approach (Eu-lerian approach) to vehicular movement, to pollutants' emission,...
