Using Empirical Mode Decomposition To Study Periodicity And Trends In Extreme Precipitation, Noah Pfister
Using Empirical Mode Decomposition To Study Periodicity And Trends In Extreme Precipitation, Noah Pfister
Graduate College Dissertations and Theses
Classically, we look at annual maximum precipitation series from the perspective of extreme value statistics, which provides a useful statistical distribution, but does not allow much flexibility in the context of climate change. Such distributions are usually assumed to be static, or else require some assumed information about possible trends within the data. For this study, we treat the maximum rainfall series as sums of underlying signals, upon which we perform a decomposition technique, Empirical Mode Decomposition. This not only allows the study of non-linear trends in the data, but could give us some idea of the periodic forces that …
Sustainable Agriculture In Vermont: Economics Of Climate Change Best Management Practices And The Complexity Of Consumer Perceptions Of Raw Milk, Alexander Paul Helling
Sustainable Agriculture In Vermont: Economics Of Climate Change Best Management Practices And The Complexity Of Consumer Perceptions Of Raw Milk, Alexander Paul Helling
Graduate College Dissertations and Theses
Changing weather patterns, the declining social fabric of rural communities, and economic uncertainty increasingly pose challenges to Vermont communities. The socially and environmentally embedded production practices within sustainable agriculture present a potential solution to these problems. In order to make the most of the potential benefits of these practices society must maximize their adoption. This requires an understanding of both farmer adoption of these practices and consumer perceptions of the resulting food products. This thesis contributes two original articles on sustainable agriculture through the analysis of factors driving both farmer adoption and consumer perceptions of products and practices often thought …
