Estimation of unknown pesticide levels in experimental samples is an important aspect of many agricultural and environmental studies. Such measurements are often made utilizing a “standard” dose response curve. This methodology compares the biological response of a target organism at known dosages to the response of the same organism exposed to an unknown sample. These “bioassays” are typically...

We present a parameter estimation approach for LuGre friction model based on chain-code method. The approach employs shape characteristics of friction force-displacement curve to measure the similar degree, here it is Euclidean distance, between the original curve and simulated curve. Once the Euclidean distance is smaller than the given error, we can consider the final dynamic parameters are t...

The process of classifying objects is a fundamental feature of most human pursuits, and the idea that people classify together those things that people find similar is both intuitive and popular across a wide range of disciplines. Estimation of difference between curves (curve matching) is an useful and often necessary technique in many applications, including: pattern recognition, image object...
