Abstract: An analytic method for the determination of the concentration of polysaccharide polymer in solution comprises the in-line derivatization of the polymer by reaction with sulfonate dye. The reaction results in an analyte-derivative, carried in a mobile phase, that can be detected and quantitatively determined by ultraviolet absorption or by fluorescence measurement. The method can provide sensitive and precise measurement in spite of limited solubility of the analyte.

Abstract: The invention is a method of spectral data classification that uses the decoupling of target chromaticity and lighting or illumination chromaticity in spectral data and the sorting and selection of spectral bands by values of a merit function to obtain an optimized set of combinations of spectral bands for classification of the data. The decoupling is performed in “delta-log” space. A rotation transform may be applied. For a broad range of parameters, correction of lighting chromaticity may be obtained by use of an equivalent “Planck distribution” temperature. Merit function sorting and band combination selection is performed by multiple selection criteria. The method achieves reliable pixel classification and target detection in diverse lighting or illumination, especially in circumstances where lighting is non-uniform across a scene, such as with sunlight and shadows on a partly cloudy day or in “artificial” lighting.

Abstract: A computer controlled environment system and method are used to provide the optimum environmental and nutritional conditions for the growth and development of seed potato cuttings for the initiation and development of tubers that can be used as the seed source for further multiplication under field conditions as seed potato stock. Use of a controlled environment system and method that provides optimum cultural conditions results in rapid growth and development of the potato cutting so as up to six crops of tubers can be harvested in a calendar year.
