摘要： In staircase forward error correction coding, a stream of data symbols are mapped to data symbol positions in a sequence of two-dimensional symbol blocks Bi, i a positive integer. Each of the symbol blocks has data symbol positions and coding symbol positions. Coding symbols for the coding symbol positions in each symbol block Bi in the sequence are computed. The coding symbols are computed such that, for each symbol block Bi that has a preceding symbol block Bi−1 and a subsequent symbol block Bi+1 in the sequence, symbols at symbol positions along one dimension of the preceding symbol block Bi−1, concatenated with the data symbols and the coding symbols along the other dimension in the symbol block Bi, form a codeword of a FEC component code, and symbols at symbol positions along the one dimension of the symbol block Bi, concatenated with the data symbols and the coding symbols along the other dimension in the subsequent symbol block Bi+1, form a codeword of the FEC component code. Thus, each row in [Bi−1T Bi] and each column in [ B i B i + 1 T ] , for example, is a valid codeword.

摘要： Interleavers based on golden-section increments are disclosed for use with Turbo and Turbo-like error-correcting codes. The interleavers have a tendency to maximally spread the error-bursts generated by an error-burst channel or decoder, independent of the error-burst length. The code block size uniquely defines a golden section increment without having to perform a time consuming search for the best increment value. The disclosed embodiments include golden relative prime interleavers, golden vector interleavers and dithered golden vector interleavers. Also disclosed are methods to reduce the size of memory required for storing the interleaving indexes.

摘要： The invention comprises an enhancement to max-log-APP processing that significantly reduces performance degradation associated with introducing the "max" approximation into log-APP computations, while still maintaining lower computational complexity associated with max-log-APP processing. This enhancement is achieved by adjusting extrinsic information produced by a max-log-APP process where the magnitude of the extrinsic information is reduced, for example, by multiplying it with a scale factor between 0 and 1.

摘要： An electric heating assembly for use with an electric kettle or similar liquid heating apparatus has a resistance heating wire disposed within a metal sheath and connected to pins which project from respective ends of the sheath. A temperature sensitive cut-out device is connected in thermal transfer relationship to a sleeve or liner of thermally conductive material which is fitted into the element sheath at one end thereof in thermal transfer relationship with the inner surface of the sheath. The sleeve or liner extends into the sheath a sufficient distance to surround a heated portion of the resistance heating wire adjacent its connection to the inner end of the respective pin.

摘要： A method for determining at least one dynamic flow characteristic of a multiphase flow circulating in a pipe, said flow being composed of an aqueous phase and a hydrocarbon (oil) phase. Oxygen atoms in the aqueous phase are activated by irradiation with neutrons at a chosen first location in the pipe. The concentration of activated oxygen at a chosen second location in the pipe is measured with a detector as a function of time t, so as to obtain at least one signal S(t). Then a relationship is fitted to the signal S(t) so as to derive the values of the velocity U of the aqueous phase. The slip velocity v.sub.s of a dispersed phase relative to the velocity of a continuous phase is also advantageously determined. From the values of velocities U and v.sub.s and from the volume fraction y.sub.1 of the continuous phase in the pipe (obtained by an ancillary measurement), the volumetric flow rates of the phases are determined.

摘要： Once the drilling of an oil or gas well is finished the bore must be cased and cemented. It is important that the cement lining be complete, and to ensure this it is necessary to sweep out the mud in the annulus ahead of the rising cement. Unfortunately, this often proves difficult, and various procedures and mechanisms have been devised in the past to improve the chances of achieving efficient mud-removal and forming a complete cement lining, though none have been truly successful. One of the techniques presently employed involves the utilization of a wash, but it has been noted that such a wash, even when turbulent, has very little component of its movement in the annulus in a direction other than up along the annulus, and that as a result it has very little effect on gelled mud deposits, especially those in the small casing/bore inter-distance of a severely eccentric casing. It has now been discovered that a considerably increased amount of lateral motion, and thus a very significantly enhanced degree of mud removal capability, is provided if the liquid be a multiphase liquid in which one of the phases is a gas--in other words, if the liquid be full of bubbles--and the invention provides a cleaning method particularly suitable for the cleaning of gelled mud deposits off the casing and bore walls of an oil/gas well prior to cementing the casing in place, in which there is caused to flow over and in contact with the dirty surface a "burbulent" liquid.

摘要： Multiple data permutation operations in respective different dimensions are used to provide an overall effective data permutation using smaller blocks of data in each permutation than would be used in directly implementing the overall permutation in a single permutation operation. Data that has been permuted in one permutation operation is block interleaved, and the interleaved data is then permuted in a subsequent permutation operation. A matrix transpose is one example of block interleaving that could be applied between permutation operations.

摘要： Apparatus is described for rapidly coating a large area, or for rapidly producing a powder. In one embodiment, a liquid having a coating chemical is pumped from a liquid reservoir to a distribution manifold. From the distribution manifold, the liquid is carried under pressure to a geometric array, e.g., linear, of atomization nozzles. Flow equalization means are provided for equalizing the flow of the liquid delivered to each nozzle, and, preferably, means are provided for equalizing the temperature of the liquid delivered to each nozzle. The liquid, upon exiting the nozzles with the attendant pressure drop atomizes. The atomized liquid coats a substrate either in non-reacted or reacted form, or forms a powder. In a preferred embodiment, a solution of precursor chemical is reacted in a geometric array of flames produced at the nozzles, and a coating material produced in the flame coats the substrate, or a powder is formed. In another embodiment, vaporized precursor and vaporized are fed to a burner chamber having a linear exit slit. The vapor exiting the slit is burned, and material produced in a flame reaction are deposited on a substrate, or the powder formed is collected.
