To cope with computing power limitations, air quality models that are used in integrated assessment applications are generally approximated by simpler expressions referred to as "source-receptor relationships (SRR)". In addition to speed, it is desirable for the SRR also to be spatially flexible (application over a wide range of situations) and to require a "light setup" (based on a limited num...

Stormwaters, flowing into storm sewers, are known to significantly increase the annual pollutant loads entering urban receiving waters and this results in significant degradation of the receiving water quality. Knowledge of the characteristics of stormwater pollution enables urban planners to incorporate the most appropriate stormwater management strategies to mitigate the effects of stormwater...

Service wait time is a key performance indicator in the food service industry. A real-case scenario of a cafeteria situated on a college campus is studied for service time. During the lunch hours, there is always a large queue that impacts serviceability. This study identifies the stations and events where the wait time increase and suggests with a solution. A discrete event simulation (DES) mo...

This paper focuses on the use of Atmospheric Dispersion and Impact Assessment Modeling (ADIAM) in nuclear emergency management. As a complement to field measurements, these tools participate in emergency decision support regarding the assessment of impacted areas and population protection countermeasures. This paper aims to study how this expertise is used during crisis situation and question t...

A model for the statistical analysis of the total amount of insurance paid out on a policy is developed and applied. The model simultaneously deals with the number of claims (zero or more) and the amount of each claim. The number of claims is from a Poisson based discrete distribution. Individual claim sizes are from a continuous right skewed distribution. The resulting distribution of total cl...

Skin, as a protective organ of the body, is subject to many factors from within the body and from the outside environment that constantly challenge its integrity and protective functions. Diverse factors such as ultraviolet light (UV), atmospheric pollution, increased atmospheric ozone, wounds, infections, hormonal status, metabolic diseases, psychological stress and the natural process of agin...

Being part of a highly dynamic system, contaminated sediments are especially in need of an integrated management approach. Due to change in importance from source to diffuse pollution and the variety of chemical substances in the environment, different scientific fields need to cooperate and incorporate their data in a common risk assessment scheme. Public perception of risk that is associated ...

The present MYPLANET project responds to the first FP7-call “PEOPLE-INITIALTRAINING-ITN-2007-1” published by the European Commission. This collaborative initial training network represents a European initiative to train a new generation of engineers in the field of high performance computing applied to the numerical combustion simulation, energy conversion processes and related atmospheric poll...

Ecosystems are dynamic systems and the study of their functioning and evolution requires the development of dynamic biogeochemical models. A wide application and a pronounced development of this type of model has taken place during the last two decades due essentially, to the development of computer technology, which has permitted the handling of very complex mathematical systems, and also to t...

The paper presents some preliminary results from numerical simulations of meteorological processes and air pollutant transport based on field measurements perfomed during winter 2006 at three target areas along the Adige Valley (Northern Italy) within the project ALPNAP, funded by the European Regional Development Fund under the initiative Interreg III B "Alpine Space"(cf. de Franceschi and Zar...
