Abstract We examine the design of bid selection protocols and settlement rules in ancillary service markets. Such markets are typically operated by an independent system operator (ISO) for competitive procurement of reserves that are needed to...
Accurate quantification of land use/cover change (LULCC) is important for efficient environmental management, especially in regions that are extremely affected by climate variability and continuous population growth such as West Africa. In this context, accurate LULC classification and statistically sound change area estimates are essential for a better understanding of LULCC processes. This st...
