20150195005 | METHOD AND APPARATUS FOR FAST AND ACCURATE ACQUISITION OF CROSSTALK COEFFICIENTS - In accordance with an embodiment, the method includes inserting a plurality of crosstalk probing signals within the wired multi-carrier communication system for probing the crosstalk from respective ones of the plurality of disturber lines into the victim line, carrying out crosstalk measurements over the victim line, and estimating the crosstalk coefficients from the crosstalk measurements. The method further includes organizing the plurality of disturber lines into subsets of disturber lines, and individually assigning disjoint groups of carriers to the respective subsets of disturber lines. The insertion of the plurality of crosstalk probing signals is confined within the respectively assigned groups of carriers. The subsets of disturber lines and/or the groups of carriers used for a second or subsequent iteration are tailored based on crosstalk characteristics observed for the respective disturber lines during a pervious iteration. | 07-09-2015 |

20150095594 | Method and Apparatus for Bit-Interleaving - A manner of processing data for transmission in a data communication network. Node having a main memory and an interleaver is provided. Received data is stored in the main memory and a bandwidth map is prepared. The data is then selectively read out and pre-processing according to the bandwidth map and stored in an interleaver memory. The date is later read out and post-processed before interleaving into a downstream data frame. The pre- and post-processing provide the data in a more efficient form for interleaving. | 04-02-2015 |

20100211367 | SYSTEM AND METHOD OF INTEGRATING SUBTERRANEAN COMPUTER MODELS FOR OIL AND GAS EXPLORATION - The invention provides a system and method for integrating petroleum system and geomechanical computer models for use in oil and gas exploration. In one embodiment, the invention provides a petroleum system model capable of analyzing data relating to a subterranean formation and calculating the geometry and geochemistry of each layer of the formation through geologic time. The present invention also provides a geomechanical model in communication with the petroleum system model such that information concerning each layer of the subterranean formation may be shared and cross-referenced as an iterative operation prior to the analysis of subsequent layers. At each step of the iterative operation, results are calculated, validated, and cross-referenced in order to produce improved reliability estimates of petroleum charge and mechanical seal integrity for the subterranean formation. | 08-19-2010 |
20120136636 | FINITE ELEMENT ADJUSTMENT FOR BASIN FAULTS - A method can include providing finite elements described with respect to a horizontal coordinate axis and a vertical coordinate axis to model a sedimentary basin, identifying a finite element having a horizontal boundary intersected by a fault, subdividing the finite element into two finite elements, and representing the fault along a boundary between the two finite elements. Various other apparatuses, systems, methods, etc., are also disclosed. | 05-31-2012 |

20140257701 | OUTPUT COMPRESSION FOR GEOLOGICAL STRATA PHYSICAL PROPERTY MODELING - Methods, systems, and computer-readable media for compressing topological grid data for layered geological strata are described. The techniques include obtaining topological grid data for a layered geological structure, where the topological grid data includes a plurality of cell representations, a majority of the cell representations including at least one data value, where the topological grid data includes at least one pinch-out cell representation lacking a data value. The techniques also include interpolating a data value for the at least one pinch-out cell representation to produce interpolated topological grid data. The techniques also include transforming the interpolated topological grid data to obtain frequency domain interpolated topological grid data. The techniques also include truncating ordered coefficients of the frequency domain interpolated topological grid data to obtain truncated frequency domain interpolated topological grid data. The techniques also include storing on a non-transitory storage medium the truncated frequency domain interpolated topological aid data. | 09-11-2014 |
