Abstract: In classical steam assisted gravity drainage (SAGD) processes for in situ extraction of carbon-containing materials, vapor is introduced into the reservoir at a high pressure, requiring a comparatively great technical effort. According to the invention, condensed water is used that is introduced into the reservoir via an injection pipe (101, 106, 107) and is horizontally conducted inside the pipe within the reservoir such that the water can evaporate in situ and the heat can be applied to the reservoir. This results in a significantly simplified technical installation. In particular, there is no need to desalinate the water at great expense as in prior art.

Title: Scalable speech and audio encoding using combinatorial encoding of mdct spectrum
Inventor: REZNIK YURIY
IPC: G10L19/02
Filed: 2008-10-22
Abstract: A scalable speech and audio codec is provided that implements combinatorial spectrum encoding. A residual signal is obtained from a Code Excited Linear Prediction (CELP)-based encoding layer, where the residual signal is a difference between an original audio signal and a reconstructed version of the original audio signal. The residual signal is transformed at a Discrete Cosine Transform (DCT)-type transform layer to obtain a corresponding transform spectrum having a plurality of spectral lines.  The transform spectrum spectral lines are transformed using a combinatorial position coding technique. The combinatorial position coding technique includes generating a lexicographical index for a selected subset of spectral lines, where each lexicographic index represents one of a plurality of possible binary strings representing the positions of the selected subset of spectral lines. The lexicographical index represents non-zero spectral lines in a binary string in fewer bits than the length of the binary string.

Title: Rate-distortion quantization for context-adaptive variable length coding (cavlc)
Inventor: KARCZEWICZ MARTA
IPC: H04N7/26
Filed: 2009-04-10
Abstract: In general, this disclosure provides techniques for quantization of the coefficients of video blocks in a manner that can achieve a desirable balance of rate and distortion. The described techniques may analyze a plurality of quantization levels associated with each individual coefficient to select the quantization level for the individual coefficients that results in a lowest coding cost. Since CAVLC does not encode each coefficient independently, the techniques may compute the coding costs for each of the candidate quantization levels associated with the individual coefficients based on quantization levels selected for previously quantized coefficients and estimated (or predicted) quantization levels for subsequent coefficients of a coefficient vector. The quantization levels for each of the coefficients are selected based on computed coding costs to obtain a set of quantized coefficients that minimize a rate-distortion model.
