Computer-aided methods in rheometry

During the many years of operating a rheometry laboratory for a wide range of chemists, physicists, and engineers (graduate students and postdocs) at the University of Massachusetts, we have developed a comprehensive set of computer-aided Theological characterization methods for polymeric liquids and solids. In addition to performing the best possible rheometry experiments, the aim was to tailor data analysis methods to rheometry and thus obtain the optimum amount of information from the data without reading artefacts into the data (overfitting). This avoidance of overfitting is a major concern which should be addressed more widely (Winter, 1997) in order to utilize computer-aided methods to their fullest extent.
