Based on time series data of SPOT / VGT and DMSP / OLS, the built-up and non-built-up areas of countries in South Asia were extracted via the local support vector machine method. Accuracy assessment showed that Kappa coefficients were above 0.85 were achieved in 1998 and 2013. Based on built-up areas detected, the urban expansion of the eight South Asian countries and their major cities were analyzed...
The surface mounting equipment (SME) is critical and complex in electronic assembly process. The key issue of SME is to realize accurate positioning and high-speed under the influence of parametric uncertainties (e.g., unknown gravitational load) and uncertain nonlinearities (e.g., friction). For achieving this aim, the adaptive robust control (ARC) based on dynamic LuGre model algorithm is proposed...
