Abstract: The present invention relates to a method and apparatus to synchronise audio and video data. More particularly, the present invention relates to a loop-based audio-visual mixing apparatus and method for synchronising a plurality of videos and their corresponding audio streams to create audio-visual compositions. According to one aspect, there is provided a method for creating a synchronised lineal sequence from multiple inputs of audio and video data, comprising the steps of: providing a first input, comprising audio and video data; providing one or more subsequent inputs, comprising audio and video data; determining at least one rhythm metric unit for each input; queueing the or each subsequent inputs such that the or each subsequent input is triggered at a beginning of a next said rhythm metric unit of a determined input.

Abstract: Disclosed are methods for simulating pressures and saturations of oil, gas, and water in an oil reservoir with production and injection wells, which include (1) using of new approximating linear algebraic (finite difference) equations that more accurately represent actual pressures by basing the equations on new functional forms: ln(r) or 1/r, (2) solve the set equations using by defining a coarse grid array and a fine grid array nested in the fine grid array, and solving the coarse grid array and using the resulting solution to fix points in the fine grid array before it is solved, and (3) defining and solving a dynamic grid array based upon constant saturation contours.
