摘要:
A system and method are described for progressively efficiently filtering and gathering netflow data. Flow records are analyzed to find out which keys (addresses, conversations, protocols etc) meet defined filter parameters. The netflow data is processed and a data structure of fixed size is continually maintained in order to facilitate efficient retrieval of the gathered netflow data.

A method, an apparatus, and a software product to process a plurality of input audio signals. The apparatus accepts a plurality of input signals and includes a multi-input, multi-output reverberator arranged to generate a set of output signals including delayed reverberation components simulating the reverberations a listener is likely to hear in a listening environment. The apparatus further includes a multi-input, two-output filter accepting the outputs of the reverberator and the plurality of input terminals, providing outputs for the left and right ears, and configured to implement a set of head related transfer functions corresponding to a listening environment and a set of directions of a listener in the listening environment. The apparatus is such that a listener listening to the outputs through headphones has the sensation of listening to the plurality of input audio signals as if they are emanating from a plurality of loudspeakers spatially located in the listening environment at a corresponding plurality of directions.

A high sensitivity glow discharge ion source system for analyzing particles includes an aerodynamic lens having a plurality of constrictions for receiving an aerosol including at least one analyte particle in a carrier gas and focusing the analyte particles into a collimated particle beam. A separator separates the carrier gas from the analyte particle beam, wherein the analyte particle beam or vapors derived from the analyte particle beam are selectively transmitted out of from the separator. A glow discharge ionization source includes a discharge chamber having an entrance orifice for receiving the analyte particle beam or analyte vapors, and a target electrode and discharge electrode therein. An electric field applied between the target electrode and discharge electrode generates an analyte ion stream from the analyte vapors, which is directed out of the discharge chamber through an exit orifice, such as to a mass spectrometer. High analyte sensitivity is obtained by pumping the discharge chamber exclusively through the exit orifice and the entrance orifice.
摘要:
A method of processing a series of input audio signals representing a series of virtual audio sound sources placed at predetermined positions around a listener to produce a reduced set of audio output signals for playback over speaker devices placed around a listener, the method comprising the steps of: (a) for each of the input audio signals and for each of the audio output signals: (i) convolving the input audio signals with an initial head portion of a corresponding impulse response mapping substantially the initial sound and early reflections for an impulse response of a corresponding virtual audio source to a corresponding speaker device so as to form a series of initial responses; (b) for each of the input audio signals and for each of the audio output signals: (i) forming a combined mix from the audio input signals; and (ii) forming a combined convolution tail from the tails of the corresponding impulse responses; (iii) convolving the combined mix with the combined convolution tail to form a combined tail response; (c)for each of the audio output signals: (i) combining a corresponding series of initial responses and a corresponding combined tail response to form the audio output signal.
摘要:
A technique for identifying deviations in patterns of data traffic between host devices communicating over a network involves establishing a baseline traffic distribution by categorizing data traffic during a learning period. The baseline traffic distribution includes a list of categories and a metric value and a measure of variability of the metric value for each category in the list. An observed traffic distribution is generated by categorizing data traffic during an observation period. The observed traffic distribution includes a list of categories and a metric value associated with each category in the list. An alarm is generated in response to at least one of the metric values of the categories of the observed traffic distribution deviating significantly from the corresponding metric value in the baseline traffic distribution based on a pair-wise comparison of the observed metric values with respective thresholds established for corresponding categories of the baseline traffic distribution.

A method of orally administering jojoba for fat reduction, blood lipid reduction, and cancer prevention and treatment in humans is disclosed. The method incorporates a sufficient quantity of jojoba, defatted jojoba meal, jojoba extract, defatted jojoba meal extract, naturally derived or synthesized simmondsin, or any naturally derived or synthesized simmondsin derivative or analogue, including aglycon, or any mixture thereof into an individual's diet in the form of a food, dietary supplement, or drug to provide simmondsin component in an amount greater than 0.01% of one's total daily diet by weight, or 0.05 gram/day. The dosage amount and duration of the administration can vary to achieve and maintain one's desired body composition and blood lipid levels. The dosage and duration of administration are increased for cancer prevention and treatment.
