    摘要： An introduction of nuclear fusion into conventionally fission-based nuclear reactors. Particularly, coolant in the reactor serves as the secondary fuel that absorbs neutrons from the fission core, and releases energy through fusion reactions. Molten Lithium is the preferred coolant in the invention, as it produces Helium gas through the neutron-Lithium fusion without leaving any radioactive or chemical impact to the environment. A Helium pressure controller is also introduced in the system to manage the Helium gas produced by nuclear reactions of the secondary fuel. Lithium Chloride (LiCl) is proposed as the secondary coolant in lieu of the commonly used molten salt in order to achieve higher power production efficiency. A reactor based on the proposed system requires less space than a conventional reactor of the same power. It is a better choice than conventional nuclear reactors when space is a key constraint, for example, on a container ship.

    摘要： Techniques and tools for encoding enhancement layer video with quantization that varies spatially and/or between color channels are presented, along with corresponding decoding techniques and tools. For example, an encoding tool determines whether quantization varies spatially over a picture, and the tool also determines whether quantization varies between color channels in the picture. The tool signals quantization parameters for macroblocks in the picture in an encoded bit stream. In some implementations, to signal the quantization parameters, the tool predicts the quantization parameters, and the quantization parameters are signaled with reference to the predicted quantization parameters. A decoding tool receives the encoded bit stream, predicts the quantization parameters, and uses the signaled information to determine the quantization parameters for the macroblocks of the enhancement layer video. The decoding tool performs inverse quantization that can vary spatially and/or between color channels.

    摘要： Aspects of the present invention relate to systems, methods and devices for upsampling images and design of upsampling filters. Some aspects relate to a determination of a phase offset position in a higher resolution picture relative to a lower resolution picture. Interpolation filter coefficients for some filters may then be selected based on the filter offset. Other aspects relate to selection of coefficients for filters that are not dependent on the phase offset. In certain implementations, a weighting factor may be used to combine the effects of a phase-offset-dependent filter and an independent filter.

    摘要： Reduced complexity inverse discrete cosine transform (IDCT) masks and a method for reducing the number of IDCT calculations in video decoding are provided. The method comprises: accepting an n×m matrix of DCT coefficients; performing (n−y) horizontal IDCT operations, where y is greater than 0; performing y scaling operations; and, generating an n×m block of pixel information. Some aspects of the method further comprise: performing (m−z) vertical IDCT operations, where z is in the range between 0 and m/2. In some aspects, performing (n−y) horizontal ICDT operations includes performing IDCT operations for the first (n−y) horizontal rows. Then, performing y scaling operations includes: selecting the DC component from the first position of each horizontal row; scaling the selected DC component; and, copying the scaled DC component into the remaining positions of each of horizontal row.
