摘要： The present invention relates to an encoding method processing video object planes (VOPs) of I, P or B type and including a dynamic allocation of said VOPs. According to said method, for each input frame a preliminary forward motion estimation is carried out between current and previous frames. Current and previous motion fields are then used to evaluate a coherence factor, expressed as connected to the sums of local differences within current and previous motion field. According to the value of the coherence factor with respect to an empirically determined threshold, a decision is finally taken on the type of the frame to be coded.

摘要： The invention relates to encoding of an input sequence of digital images delivering a base and an enhancement layer bitstream for transmission of video data in real time over a fluctuating-rate transmission channel. The method distributes the encoded data for the images of said sequence between two subsequences of base and an enhancement layer and evaluates degree of occupation of two associated buffers. A notional (virtual, dummy) bi-directional image is created in one of the subsequences which is intended to receive stuffing data, when the degree of occupation on the buffer associated with said subsequences isbelow a predetermined threshold. This method enables the adding of stuffing data in a case not provided for by the MPEG-4 standard, for example, for a sequence encoded in the rectangular mode and having no (regularly coded) bi-directional images (B-frames).

摘要翻译： 本发明涉及一种数字图像的输入序列的编码，该数字图像传送用于在波动率传输信道上实时传输视频数据的基本和增强层比特流。该方法在基站和增强层的两个子序列之间分配用于所述序列的图像的编码数据，并评估两个相关缓冲器的占用程度。当与所述子序列相关联的缓冲器上的占用程度低于预定阈值时，在旨在接收填充数据的子序列之一中创建概念（虚拟，虚拟）双向图像。该方法能够在不由MPEG-4标准提供的情况下添加填充数据，例如，对于以矩形模式编码并且没有（有规则编码的）双向图像（B帧）的序列。

摘要： In the Improved PB-frames mode, one of the options of the H.263+ Recommendation, a macroblock of a B-frame may be encoded according to a forward, a backward or a bidirectional prediction mode. The invention relates to a method of encoding a sequence of pictures defining a strategy for the choice of a prediction mode among the three possible ones in the encoding of B-macroblock. This strategy is based upon SAD(Sum of Absolute Difference) calculations and motion vectors coherence and allows to use backward prediction when scene cuts occur. The calculations are here performed on original pictures allowing less calculation and reduction in CPU burden. The invention also relates to an encoding system for carrying out said method and including a computer-readable medium storing instructions that allow the implementation of this method.

摘要： A turbine blade that may include an airfoil and a blade dovetail, the blade dovetail being shaped corresponding to a dovetail slot in a turbine disk. The blade dovetail may include a dovetail backcut sized and positioned according to blade geometry to maximize a balance between stress reduction on the disk, stress reduction on the blade, a useful life of the turbine blade, and maintaining or improving the aeromechanical behavior of the turbine blade. A start point of the dovetail backcut, which defines a length of the dovetail backcut along a dovetail axis, may be determined relative to a datum line positioned a fixed distance from a forward face of the blade dovetail along a centerline of the dovetail axis. The start point of the dovetail backcut may be at least approximately 1.645 inches in an aft direction from the datum line.

摘要： Blade load path on a gas turbine disk can be diverted to provide a significant disk fatigue life benefit. A plurality of gas turbine blades are attachable to a gas turbine disk, where each of the gas turbine blades includes a blade dovetail engageable in a correspondingly-shaped dovetail slot in the gas turbine disk. In order to reduce gas turbine disk stress, an optimal material removal area is defined according to blade and/or disk geometry to maximize a balance between stress reduction on the gas turbine disk, a useful life of the gas turbine blade, and maintaining or improving the aeromechanical behavior of the gas turbine blade. Removing material from the material removal area effects the maximized balance.

摘要： A turbine bucket airfoil has a conical fillet about the intersection of the airfoil tip and tip shroud having a nominal profile in accordance with coordinate values of X and Y, offset 1, offset 2 and Rho set forth in Table I. The shape parameters of offset 1, offset 2 and Rho define the configuration of the fillet at the specified X and Y locations about the fillet to provide a fillet configuration accommodating high localized stresses. The fillet shape may be parabolic, elliptical or hyperbolic as a function of the value of the shape parameter ratio of D1 D1 + D2 at each X, Y location where D1 is a distance between an intermediate point along a chord between edge points determined by offsets O1 and O2 and a shoulder point on the fillet surface and D2 is a distance between the shoulder point and an apex location at the intersection of the airfoil tip and tip shroud.
