  • Modeling Tip: Importing & Exporting Traffic Data in CALRoads View

    The CALINE series of models was developed to estimate pollutant concentrations from motor vehicles at roadway intersections. It includes three primary models: CALINE, CAL3QHC, and CAL3QHCR. The latter allows processing of real meteorological data (up to one year) and input of vehicular emissions, traffic volume, and signalization (ETS) data. Data reflecting traffic conditions for individual hours ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Environmental modelling for blue collars

    Model complexity and the ‘breakpoint of diminishing returns’; ‘physical’ vs. ‘conceptual’ modelling; the relevance and limits of the heuristic solutions; screening vs. analytical modelling; perceptions of uncertainties, calibration and sensitivity analysis; and the ‘ethics in modelling’ – are only a few issues outstanding in the volatile philosophy of the environmental modelling. Glossing on ...

  • Modelling trade and environmental linkages in China

    Interactions between trade and the environment have been studied extensively as a reaction to the pressure that the accelerated pace of globalisation has placed on environment and trade. Distinguishing itself from previous work, this study focuses on a modelling analysis of the interactions between trade and the environment in China. A non-linear simultaneous equation trade and environment model ...

  • Endogenous technology and environmental quality in economic models

    The debate on the relationship between the economy and the environment focuses on the question whether there is a trade-off between economic growth and environmental quality. In order to enable a quantification of this essentially empirical question, it is necessary to integrate the environment into economic models. This article considers the integration of the environment in models of economic ...

  • Understanding QSPR uncertainty in environmental fate modeling

    In cases where experimental data on chemical‐specific input parameters are lacking, chemical regulations allow the use of alternatives to testing, such as in silico predictions based on quantitative structure‐property relationships (QSPRs). Such predictions are often given as point estimates; however, little is known about to what extent uncertainties associated with QSPR predictions contribute ...

  • An Interactive Environmental Economy Model for Energy Cycle in Iran

    ABSTRACT The growing world economy calls for saving natural resources with sustainable development framework. This paper intends to look at the environment-energy interface (impacts on the environment stemming form the energy sector) and to propose measures for reducing this impact without trying to impede economic development. In addition, this paper estimates the amounts of energy subsidies ...

  • On the formulation of environmental fugacity models and their numerical solutions

    Multimedia models based on chemical fugacity, solved numerically, play an important role in investigating and quantifying the environmental fate of chemicals such as persistent organic pollutants (POPs). These models have been utilised extensively in the study of the local and global distribution of chemicals in the environment. This paper describes potential sources of error that may arise ...

  • Regulatory models for environmental impact assessments in Hungary

    This paper describes the methodology and input requirements of environmental impact assessments regulated in Hungary by national standards for more than 10 years. The main characteristics are (a) various models simulate the impact of point, multi-source, line and area sources on local, urban and regional scales, (b) design transmission matrices are readily available for the greater part of the ...

  • Models of energy saving systems: the battlefield of environmental planning

    Traditionally, energy planning has been interpreted as planning for an appropriate energy supply system, based on a crude prognosis for the energy demand. Over the past couple of decades, however, the immense possibilities of regulating energy demand - and the benefits of doing it - have become increasingly recognised and also partly included in the planning. This paper first describes some ...

  • Atmospheric environmental impact assessment modelling in France

    The most widely accepted model of atmospheric dispersion for impact assessment in France is the Gaussian model of Doury. The Centre d'Etudes Atomiques (CEA) and Electricite de France (EDF) have developed their own software systems, which include several compatible or nested meteorological, trajectory, and dispersion codes. These systems are fitted to the various atmospheric scales from regional ...

  • Improved environmental multimedia modeling and its sensitivity analysis

    Modeling of multimedia environmental issues is extremely complex due to the intricacy of the systems with the consideration of many factors. In this study, an improved environmental multimedia modeling is developed and a number of testing problems related to it are examined and compared with each other with standard numerical and analytical methodologies. The results indicate the flux output of ...

  • Environmental Noise

    Introduction The ability to hear sounds is a sensory function vital for human survival and communication. However, not all sounds are wanted. 'Unwanted sounds', for which the term 'noise' is normally used, often have their origin in human activities (mainly transport, industry and households). This article addresses environmental noise ­ also referred to in the scientific literature as ...

  • A Process Flow Model of ISO 14001 for the Implementation of an (EMS) Environmental Management System

    ABSTRACT   There is increasing interest all over the world in Environmental Management Systems.  Many Japanese electronic companies have mandated that their plants should be ...


  • A conflict measure model and its application to supplier evaluation under environmental uncertainty

    As environmental issues are of increased concern, many enterprises have participated in some forms of green-purchasing initiatives. Beside the traditional criteria, the supplier's environmental consciousness, environmental mission, advances in developing environmentally friendly goods, etc., should be evaluated. The attitude difference among supply chain partners will create potential problems ...

  • Probability density estimation in stochastic environmental models using reverse representations

    The estimation of probability densities of variables described by stochastic differential equations has long been done using forward time estimators, which rely on the generation of forward in time realizations of the model. Recently, an estimator based on the combination of forward and reverse time estimators has been developed. This estimator has a higher order of convergence than the classical ...

  • Application of dispersion models in the environmental assessment process in the United Kingdom

    The UK planning process has traditionally been separated from the licensing process as far as industry is concerned. Implementation of the Environmental Assessment Directive (85/337/EEC) has therefore been the responsibility of planners, not pollution regulators. This is one of the reasons why there are no formalised procedures for using dispersion models in the environmental assessment ...
