The rotor position is integrant information for vector control drive system of Permanent Magnet Synchronous Motor (PMSM). In this paper, the focus is on the rotor position of PMSM detecting by the resolver sensor. The outstanding features of this sensor are its robust structure and noise insensitivity. To extract speed from the output of resolver we need(More)
Distillation is an energy intensive operation in chemical process industries. There are around 40,000 distillation columns in operation in the US, requiring approximately 40% of the total energy consumption in US chemical process industries. However, analysis of separations by distillation has shown that more than 50% of energy is spent in purifying the(More)
The field of Spatial Data warehouses has been emerging since the past decade due to the need to analyze large volumes of spatial data. The data once stored in a spatial data warehouse has to be queried using spatial online analytical processing (SOLAP) systems. The research in field of spatial data warehouses has been on conceptual models, materialization(More)
