摘要： The present invention generally relates to intravascular ultrasound (IVUS) image segmentation methods, and is more specifically concerned with an intravascular ultrasound image segmentation method for characterizing blood vessel vascular layers. The proposed image segmentation method for estimating boundaries of layers in a multi-layered vessel provides image data which represent a plurality of image elements of the multi-layered vessel. The method also determines a plurality of initial interfaces corresponding to regions of the image data to segment and further concurrently propagates the initial interfaces corresponding to the regions to segment. The method thereby allows to estimate the boundaries of the layers of the multi-layered vessel by propagating the initial interfaces using a fast marching model based on a probability function which describes at least one characteristic of the image elements.

摘要： This invention relates to a process for obtaining extruded semifinished products from high resistance aluminum alloy powder.It is characterized in that there is used particularly a powder of an aluminum-lithium alloy obtained by atomization in a neutral gas. This powder is loaded in a jacket of aluminum alloy of the 5000 type, then hot degassed under a pressure less than the atmospheric pressure; after sealing of the jacket, the unit is subjected to hot inverted extrusion and heat treated in the ambient air.The plated composite semifinished product thus obtained exhibits a very high resistance and finds its application particularly in the aeronautical industry.

摘要： In the process, at least one piece of meat is destructured by fragmenting it, and the meat fragments are transformed into a restructured meat article. The fragments are transformed into a restructured meat article by: forming a block of meat fragments by cohesive compaction of the meat fragments; removing at least a portion of the block, termed a preform; and compressing the preform between complementary surfaces for molding the preform. The meat fragment compacting device comprises two conveyor belts for cohesive compaction of the meat fragments, the belts converging from upstream to downstream relative to a direction of movement of the meat fragments. The device for compressing a preform for a meat article comprises pistons having surfaces for molding the preform, which surfaces vary from one piston to another.

摘要： A water-cooled plasma torch specially designed to drill into a refractory material is used in a method for opening a tap hole closed by a plug in a wall of a furnace. This method which is particularly well adapted for robotization, includes the step of melting and breaking up the plug closing the tap hole by means of a jet of swirling gas of high speed and high temperature, generated by the plasma torch. The main advantage of this method is that the stream of plasma gas leaving the torch has a well defined outline ensuring precise and reproducible tapping of the plug and, as a result, efficient closing of the tap hole with a new plug after the furnace has been emptied.
