Abstract: A colorimetric chemosensor molecule having a aza-macrocycle Zn (II)-complex (L.Zn) (Scheme 1, Formula 1A) which can recognize selectively and efficiently ATP (Adenosine triphosphate), a biologically significant triphosphate in aqueous medium at pH 7.4 is described. Since ATP is the source of energy in living organisms, L.Zn (Scheme 1, Formula 1A) can also be used as a staining agent in the living cells through binding to ATP, generated in situ during the metabolic process.

Abstract: To reduce the amount of storage space and computing power required to render image data, particularly building image data, primary and secondary colors may be extracted from the image data. The image data may be re-rendered using only the primary and secondary colors. The re-rendered image may be evaluated for patterns, the patterns thresholded to bi-level data and a Discrete Fourier Transform (DFT), or equivalent, may be performed on the bi-level data. Low order coefficients may be discarded depending on level accuracy desired. DFT coefficients and color data for the primary and secondary colors may then be used to construct an abstraction of the original image data, using data that is, in some cases, three or four orders of magnitude smaller than the original image data.

Abstract: A speaker recognition system generates a codebook store with codebooks representing voice samples of speaker, referred to as trainers. The speaker recognition system may use multiple classifiers and generate a codebook store for each classifier. Each classifier uses a different set of features of a voice sample as its features. A classifier inputs a voice sample of an person and tries to authenticate or identify the person. A classifier generates a sequence of feature vectors for the input voice sample and then a code vector for that sequence. The classifier uses its codebook store to recognize the person. The speaker recognition system then combines the scores of the classifiers to generate an overall score. If the score satisfies a recognition criterion, then the speaker recognition system indicates that the voice sample is from that speaker.

Abstract: A method for distributing information in a network environment is provided that includes receiving a communication flow and executing a routing decision for the communication flow that directs the communication flow to a selected one of a plurality of servers. The routing decision is based on a selected one or more user-specified parameters and on one or more data segments that reflect feedback associated with one or more of the servers. The feedback indicates one or more conditions associated with one or more of the servers.
