We collected eight field data sets of potatoes farms in five years (2004~2008) from Taiwan Seed Improvement and Propagation Station. Besides, generalized linear models were employed to estimate the proportion of the individual plant infected. By mean square error as criteria. optimal group sizes were changed from 20 to 40 plants per group so that the cost was reduced and the testing process was improved efficiently. Not only can the group-testing design advance the accuracy of testing, but it can reach to the purpose of optimization.

The main architecture of multiple WPANs accessing the HAN is proposed. The medium access control-level coordination solution applied in the access point for the coexistence of different communication protocols within WPAN is discussed. The diagram of the adaptive FRESH filter is described. The anti-interference models of the FRESH filter in the scenario of multiple WPANs accessing the HAN are proposed. The minimum mean square error convergence property of the FRESH filter with the change in data point number is analyzed.
