In a digital data processing system having an on-line file system component, a method and apparatus for archiving the contents of a selected client volume stored on the file system. The archiving is performed automatically, beginning with an initial duplication of the existing contents of the client volume into an archive volume, then continuing as changes, including additions, deletions and modifications, are made to the files comprising the client volume. Older, previously-archived versions of modified files are gracefully discarded so as to moderate the rate of growth of the archive volume. The archive volume may be used to restore the client volume, either selectively or in whole, in the event of inadvertent damage to, or loss of, files in the client volume.

An array of long carbon nanotubes (i.e. an array where the average length of the nanotubes is greater than 0.5 millimeters) is prepared by exposing a supported catalyst at elevated temperature to a gas mixture of hydrocarbon, inert gas, and a relatively low percentage of hydrogen. Addition of water vapor to the gas mixture may result in an increase in the length of the nanotubes, an increase the rate of growth, and a decrease in contamination of the array by amorphous carbon. The temperature and growth time are also chosen to minimize the amount of amorphous carbon that forms on the array. Fibers spun from the array have a higher tensile strength compared to known CNT fibers.

A method for optimizing the rate at which a given acid should be injected into a carbonate-containing rock formation during an acid injection process. The first step of the method calculates the Damkohler numbers for regimes in which kinematic force, diffusion rate and reaction rate control. The Damkohler numbers are then used to calculate the rate of growth of wormholes as a function of flux, taking into account compact dissolution, wormholing, and uniform dissolution. The calculated function is used to calculate an optimum flux for the formation. The optimum flux is then used to calculate an optimum injection rate at a given point in the acid injection process.

An exemplary fast start-up crystal oscillator with reduced start-up time. The exemplary oscillator reduces the start-up time (i.e., the time taken to attain sustained stable oscillations after the power is turned on) by increasing the negative resistance of a circuit. Increasing the negative resistance increases the rate of growth of the oscillations, thereby reducing start-up time. The exemplary crystal oscillator includes a gain stage with negative resistance. A crystal with shunt capacitance is placed in the feedback loop of the gain stage. A buffer is coupled to the gain stage such that it blocks the crystal shunt capacitance from loading the gain stage, effectively increasing the negative resistance of the gain stage. Further, an oscillation detection and control circuit is coupled between the crystal and the gain stage. The oscillation detection and control circuit connects the buffer during start-up, and disconnects the buffer once an oscillation signal attains sustained stable oscillations.

A technique for improving the performance of OFDM (Orthogonal Frequency Division Multiplexing) systems addresses the Sampling Frequency Offset (SFO) estimation and correction problems of conventional techniques and provides improved performance in a wide range of operating conditions. The technique teaches a correction scheme that uses known pilots in each OFDM symbol to estimate slope of phase error and subsequently calculate the correction factor for each of the sub-carriers in the associated OFDM symbol. The present subject matter further teaches an averaging slope estimates over a window of predetermined number of OFDM symbols to average out noise and get a refined correction factor. In addition, the present technique teaches tracking rate of growth of slope across OFDM symbols to estimate SFO, which can be used for the timing error correction in the time domain.

Feedback detection, adaptive notch filtering, and gain adjustment are combined for managing feedback.

This invention provides a continuous process of making continuous nanofibers of all kinds, such as SiC, BN, AlN, and C. Laser heating a vapor of feed-material made of all atomic elements needed to grow chosen nanofibers results in growth of nanofibers onto seed-nanostructures attached to a filament, which is then pulled up continuously at a rate controlled by a rate of growth of the nanofibers. More feed-material is supplied at a rate sufficient to enable the nanofibers to grow longer continuously without limit. Laser light focused into a doughnut shape provides a photon density gradient, which constrains the nanofibers to grow parallel to each other and in the form of cylinders, so that industrially useful structures like cables and cylinders can be made in one low cost operation and in large quantities.

A method and system for measuring the dimensions of the palpable surface of the prostate in the physician's office and calculating prostate volume, rate of growth and changes in rate of growth. A membrane with a grid pattern is located proximate the prostate. A physician moves a measurement system, formed at the end of the index finger and located in a glove, between opposite margins of the prostate. The measurement system counts the grid elements between the margins that translate into a quantitative measurement of size of the palpable surface of the prostate.

A system and method suppresses chattering events in a storage system by determining a suppression level based upon a rate of growth of log files. An event management system of the storage system calculates a histogram and a set of statistics including a mean and standard deviation associated with non-chattering events. A cutoff point is determined for the non-chattering events and is utilized for each received event to determine if the received event is a chattering event. Events determined to be a chattering event are suppressed according to a predefined suppression rate.
