Abstract: An apparatus for recovering symbol timing in a CAP-based high-speed communication system such as an ADSL or VDSL, using a single-sided prefilter pair, in which timing information is obtained by means of the single-sided prefilter pair and a multiplier instead of a squaring unit used in general communication systems, for the recovery of accurate data, so that the symbol timing can be recovered through a digital signal process at a clock rate which is four times as high as a symbol transmission rate. According to the present invention, the single-sided prefilter pair and multiplier are used instead of the squaring unit spreading a frequency band. Therefore, the frequency band is not spread, so that the timing can be obtained with no signal overlapping due to sampling, although a sampling frequency is four times as high as a symbol frequency.

Abstract: A phonetic distance calculation method for similarity comparison between phonetic transcriptions of foreign words. A system manager defines character element transformation patterns occurrable between phonetic transcriptions derived from the same foreign language. A system generates new phonetic transcriptions according to the defined character element transformation patterns and assigns a demerit mark to each of the generated phonetic transcriptions according to a phonetic distance. A minimum phonetic distance between each of the generated phonetic transcriptions and a given phonetic transcription is calculated on the basis of a minimum edit distance calculation method. Any one of the generated phonetic transcriptions with a smallest one of the calculated minimum phonetic distances is determined to be most similar to the given phonetic transcription.

Abstract: In a multi-chamber tube in which a partition extending longitudinally through the body portion of the tube divides the interior thereof into the plurality of chambers each for containing respective substances to be discharged in combination from the tube, unwanted fluctuations in the amount of substances discharged from the tube can be reduced by the partition extending through the tube at an angle relative to the closure seam at the filling opening at the bottom of the tube.

Abstract: A method for altering wettability of a reservoir formation includes the steps of providing a water-based fluid containing a wettability altering coating system; and flowing the fluid into a reservoir so as to coat the reservoir with the coating system.
