Scale appropriate modelling of diffuse microbial pollution from agriculture

Using efficient numerical methods in large-scale air pollution modelling

The air pollution, and especially the reduction of the air pollution to some acceptable levels, is an important environmental problem, which will become even more important in the next two-three decades. This problem can successfully be studied only when high-resolution comprehensive models are developed and used on a routinely basis. However, such models are very time-consuming, also when mode...

Modelling Agricultural Diffuse Pollution: CAP – WFD Interactions and Cost Effectiveness of Measures

Within the context of the Water Framework Directive (WFD) and the Common Agricultural Policy (CAP), the design of effective and sustainable agricultural and water resources management policies presents multiple challenges. This paper presents a methodological framework that will be used to identify synergies and trade-offs between the CAP and the WFD in relation to their economic and water reso...

Reducing nutrient pollution, challenges in agriculture

California’s Agriculture-Related Local Air Pollution Policy

Air pollution is a critical environmental issue for California, which has some of the nation’s most polluted air basins and also the nation’s most stringent set of state and local air quality standards. This paper reviews my previous work in Lin (2011), in which I examine the effects of agriculture-related local regulations in California on air quality, as measured by the number of exceedances ...

Local Appropriate Scale in Morphological Scale-space

This paper presents a novel approach to selecting appropriate scales for region detection prior to feature localization. We develop and formalize a number of requirements that should be fulllled by such an appropriate scale operator and show by theoretical considerations and experiments that a morphological opening-closing scale-space meets these requirements better than Gaussian scale-space. A...
