Sensitivity analysis of ground-level ozone concentration to emission changes in two urban regions of southeast Texas
Article Abstract:
The impact of changing emission inventory scenarios is assessed based on combinations of point, mobile, area-road and biogenic sources, on the tropospheric ozone concentration in two southeast Texas urban areas, during the rapid ozone formation event (ROFE) on August 25, 2000. The results revealed that removing Texas point source volatile organic compounds (VOC) emission gives the greatest reduction in Peak O3 concentration (128 ppbv) in the Houston area.

A multi-objective optimization approach to water management
Article Abstract:
A multi-criteria decision-making (MCDM) framework is developed to analyze production targets of water, under physical, biological, economic and environment constraints due to conflict between multiple goal requirements and the competing water demand of different sectors. It is observed that, MCDM provide better results than simple linear programming solution because they integrate the effect of all the objectives simultaneously.

A comparative study of US EPA 1996 and 1999 emission inventories in the west Gulf of Mexico coast region, USA
Article Abstract:
The spatial and diurnal emission characteristics of the gridded emission inventories are assessed and compared with those of the National Emission Trend 1996 (NET96). It was found that National Emission Inventory 1999 (NEI99) data exhibit greater emissions with respect to point and mobile sources but smaller emissions with respect to area sources when compared to the corresponding gridded NET96 data in the same study domain.
