  • Publication number: 20190339279
    Abstract: Starch nanoparticles (SNPs) were fluorescently labeled with 1-pyrenebutyric acid and pyrene fluorescence was employed to detect nitrated organic compounds (NOCs) in solution and on paper surfaces. Fluorescence quenching of the pyrene-labeled SNPs (Py-SNPs) by NOCs such as nitromethane, nitrotoluene (MNT), dinitrotoluene (DNT), and trinitrotoluene (TNT) was characterized in DMSO and water. Since pyrene is insoluble in water, the fluorescence of the pyrene excimer that dominated the fluorescence spectrum of the Py-SNPs dispersed in water was used for the fluorescence quenching experiments. The efficient binding of the aromatic NOCs to the pyrene aggregates of Py-SNPs dispersed in water was used to detect NOCs by Py-SNPs adsorbed at the surface of paper sheets. The low quantities of aromatic NOCs detected by the Py-SNPs demonstrate the potential of Py-SNP-coated paper for the detection of such compounds.

  • Patent number: 8090676
    Abstract: Systems and methods (300) for offline/online performance monitoring of batch processes (BPs) involving obtaining archived data (AD) obtained during runs of BP and including information defining a batch quality attribute for each run. The method also involves forming clusters by classifying AD for the runs into classes based on the batch quality attribute(s) and building a first multivariate statistical model (MSM) using AD. The method can further involve building a wavelet analysis based feature matrix (FM) using AD, forming a first projection (1200) by projecting FM onto a first MSM, building a second MSM (1300) using information obtained from the first projection, and computing centroids (C902, . . . , C918) and boundary profiles for the clusters (902, . . . , 918). The method can involve performing an online/offline performance monitoring (700/800) using an integrated version of the first and second MSM, a classification algorithm, centroids, and boundary profiles.

  • Patent number: 8078434
    Abstract: A method (300, 400, 500, 1200) for offline/online monitoring of batch processes. The method involves (312) decomposing a time domain of a batch process run (BPR) into several blocks and (334) building multivariate statistical models (MSMs) for each of them using archived data for a batch process (ABPD). ABPD comprises stored data obtained during BPRs. The method also involves (506, 1204) retrieving recently stored data (RSD) for a recent fully performed BPR run (FPRNEW) or current BPR run. The method further involves (520, 1210) building a feature vector matrix (FVM) using RSD. FVM contains feature vectors representing statistical measures of wavelet coefficients determined for variables (v0, . . . , vJ). A projection (1100, 1150, 1190) is formed by projecting feature vectors onto at least one MSM or a combined multivariate statistical model (CMSM). CMSM is a weighted average of at least two MSMs.
