    摘要: A method for the drainage of permeate gases from a flexible tubular pipe and a pipe embodied for carrying out the method. The pipe comprises at least one inner pressure sleeve, for the transport of hydrocarbons, which contain permeate gases which diffuse across the wall of the inner pressure sleeve. The pipe has an outer sleeve and several reinforcement layers, arranged in an annular zone between the outer sleeve and the inner pressure sleeve. The annular zone has transport ducts in which the permeate gases can circulate towards the removal. The method comprises a forced circulation of the permeate gases in the annular zone through the transport ducts towards the removal.

    摘要: In order to progressively transmit a digital image (IM), a method for coding the image comprises the division (E1) of the image into vectors (V.sub.m,n), the selection (E2) of a code vector (VC.sub.d) associated with an index (A.sub.d) for each of the image vectors, and the replacement (E2) of the image vectors by the indices associated with the selected code vectors, in order to produce a plane of indices (PI) representing the image. The method comprises the steps of sub-sampling (E3) the plane of indices (PI) into sub-planes of indices (SPI.sub.1 to SPI.sub.F) respectively comprising indices selected from the plane of indices, and ordering (E4) the sub-planes of indices according to a predetermined order before transmitting them.

At least one continuous longitudinal element made of a deformable material is wound in a helix with short pitch around the layer (18, 20) of armor wires to form a holding layer 24. The at least one longitudinal element is wound under longitudinal tension T0 so as to stretch its deformable material according to a relative elongation corresponding to a tensile stress σ0 less than the elastic limit value σE of the deformable material, and the elastic limit value σE corresponds to a tensile stress beyond which the deformation of the material is irreversible.

    摘要: A method for encoding is adapted to process a digital video signal composed of video frames into a bitstream. Each frame is divided into blocks and at least one block of a current frame is encoded by motion compensation using a block of a reference frame. The method comprises computing a difference frame between a current frame and a reference frame of said current frame, and selecting a subset of data representative of the difference frame computed. The subset of data selected is further encoded to obtain an encoded difference frame. Next, the encoded difference frame is decoded and the decoded difference frame is added to the reference frame to obtain an improved reference frame. Subsequently, the improved reference frame is used for motion compensation encoding of said current frame.
