  • Publication number: 20030022234
    Abstract: In a method, factors are selected for an experiment and interactions among levels of the factors are estimated. A probability value of positive interactions is then assigned for each of the estimated interactions. A combinatorial high throughput screening (CHTS) method is effected on an experimental space representing the levels and the probabilities for each interaction are adjusted according to results of the CHTS method. A system for conducting an experiment includes a reactor for effecting a CHTS method on an experimental space to produce results and a programmed controller that stores an assigned probability value for estimated positive interactions between levels of factors of the experimental space and adjusts the probabilities for each interaction according to results of the CHTS method.

  • Publication number: 20030013207
    Abstract: An experimental space comprising levels of factors is designed according to an incomplete block design and an experimental space comprising levels of factors is designed by random selection. Separate combinatorial high throughput screening experiments are effected on each experimental space to produce sets of results and best results are selected from the sets. A system for conducting an experiment includes a reactor for effecting a combinatorial high throughput screening method on an experimental space to produce results and a programmed controller that defines an experimental space comprising levels of factors according to an incomplete block design and defines an experimental space comprising levels of factors by random selection.

  • Patent number: 6460417
    Abstract: This invention relates to methods for testing elongation and cracking of coating arrays. The method includes simultaneously applying an elongating force to each of a plurality of coatings, and monitoring the coating integrity including cracks and thickness decrease in each coating. A relative performance characteristic of each coating is then determined based on a correlation between a detected crack and/or thickness decrease in the coating, and the corresponding elongating force.

  • Publication number: 20020135758
    Abstract: The present invention provides a method for quantifying structural defects of a coating composition on a given substrate, where certain structural defect-inducing tests are performed. In this method, a coating formulation is doped with a colorimetric or luminescent material. Concentration of the material depends on the quantum efficiency, excitation and emission wavelengths, and employed detection techniques, and can range from about 1 fM to about 1 mM. Before, during and/or after such tests, the coating is illuminated with a wavelength of radiation at which the reflected or transmitted color or emitted luminescence of the material in the coating is detectable with an optical detector or by visual inspection. In this fashion, the percentage of failure of the coating can be quantified as well as the level of interdiffusion of coating into substrate or substrate into coating. The method of the invention is thus particularly well-suited for the combinatorial analysis of an array of coating samples.

  • Publication number: 20020127597
    Abstract: A hybrid learning system is provided for searching an experimental space. A data mart is configured to acquire, store, and manipulate a set or meta-set of data including at least historical experimental data, descriptor data, and concurrent experimental data. A search engine is designed to use unsupervised learning techniques to select a set of evaluation points representing a corresponding set of experiments to be run, based on data from the data mart. A point evaluation mechanism provided with supervised learning modules which perform predictive processing based on the evaluation points selected by the search engine, and a scoring module performs a rating operation on outputs of the learning modules to rate the outputs of the learning modules from best to worst. The data mart search engine and point evaluation mechanism allow for a repetitive processing to refine an output of potential solutions without the requirement of continually running actual physical experiments.
