Resource Allocation Strategies in a 2-Level Hierarchical Grid System
Efficient job scheduling in grids is challenging due to the large number of distributed autonomous resources. In this paper we study various resource allocation policies in a 2-le...

Semi-Supervised Linear Spectral Unmixing Using a Hierarchical Bayesian Model for Hyperspectral Imagery
This paper proposes a hierarchical Bayesian model that can be used for semi-supervised hyperspectral image unmixing. The model assumes that the pixel reflectances result from linea...
