We consider the problem of estimating the value of a multiattribute resource, where the attributes are categorical or discrete in nature and the number of potential attribute vectors is very large. The problem arises in approximate dynamic programming when we need to estimate the value of a multiattribute resource from estimates based on Monte-Carlo(More)
BACKGROUND Macrophage infiltration and cytokine production are important in the pathogenesis of crescentic glomerulonephritis in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis. The aim of this study was to investigate whether urinary levels of chemokines, monocyte chemoattractant protein-1 (MCP-1) and fractalkine, were useful tools for(More)

W e address the problem of modeling energy resource allocation, including dispatch, storage, and the long-term investments in new technologies, capturing different sources of uncertainty such as energy from wind, demands, prices, and rainfall. We also wish to model long-term investment decisions in the presence of uncertainty. Accurately modeling the value(More)
