Abstract: Disclosed is a process for purifying monomers of Formula (II): wherein R1 and R2 are independently selected from alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, substituted alkoxy, and halogen; and R? is selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, substituted alkoxy, and halogen. After the monomer is synthesized, it is purified by column chromatography using neutral alumina and hexane as an eluent. The resulting product can also be further recrystallized using isopropanol, hexane, heptane, or toluene. Polymers formed from the purified monomer exhibit higher mobility and increased reproducibility of the mobility.

Abstract: A job log collection unit cooperates with job log management programs of copying machines to collect job logs held in the copying machines and store the collected job logs in a job log storage unit. A user change history creation unit refers to a human resource database to thereby determine whether a section which each user belongs to has been changed or not in a range of newly collected job logs. The user change history creation unit creates a user change history for each user who has encountered the change and stores the user change history in a user change history storage unit. A job log aggregation unit classifies the job logs of the job log storage unit into user sections by referring to the user change history of the user change history storage unit and aggregates the job logs in accordance with each section.

Abstract: A de-warp map is generated by applying principal component analysis (PCA) to vectors describing aspects of identified features of an object in an image. PCA provides vectors and coefficients describing curvature or image warping at selected points in the image. Estimates of the warping of the image generally are generated by interpolation and/or extrapolation from the vectors and coefficients provided by PCA. In some applications only two features need be identified. For example, the complicated curvature of the facing pages of an open book can be characterized by two vectors describing positions of top and bottom edges of the book. In such applications PCA can reduce to vector subtraction to determine a basis vector, vector addition and scaling to determine an average vector and simple assignment of known coefficient values. The de-warping map can be used to generate a de-warped version of the image.
