摘要： A device for classifying a document comprises a module to generate a data tree structure and configured to assign terms to a first plurality of nodes of the data tree structure, where each of the first plurality of nodes is assigned a weight. In assigning the weights of the first plurality of nodes, a first generation of combinations of possible weights assignable as the weights of the first plurality of nodes is obtained, and a second generation of combinations of possible weights assignable as the weights of the first plurality of nodes is obtained by performing the genetic algorithms in the first generation of combinations of possible weights. The device determines whether the document is in a document class based at least the weights of the first plurality of nodes.

摘要： Methods and systems of determining a trim line in deep draw manufacturing of a sheet metal part are disclosed. A computerized model of a sheet metal part and the addendum surface geometry are defined. At least one flange portion in the computerized model is identified. Perform a numerical simulation of unfolding of the flange towards the addendum surface by applying a first set of numerical loads to each pair of adjacent finite elements. The first set of numerical loads is configured for flattening out the pair of finite elements with a bending moment determined using relative orientations of the pair finite elements and material properties of the part. A second set of numerical loads is applied to close any remaining gap between the unfolded flange and the addendum thereafter. The outer edge of the flange portions in their final unfolded configuration is designated as a trim line.

摘要： A data-driven encoder receives fixed-length bit fields and generates variable length bit fields that are, on average, smaller than the fixed-length bit fields. The data-driven encoder removes leading zeros from a fixed-length bit field and appends a prefix code to the remaining bits that identifies the number of remaining bits. In an embodiment, the data-driven encoder may further append leading zeros before the prefix code to produce variable length bit fields having sizes that are integer multiples of bytes. The decoder identifies the original fixed-length bit fields from the variable length encoded bit fields.

摘要： The present invention relates to apparatus for retroperfusion of tissues and organs. The apparatus comprises a catheter with a proximal end for engaging a supply of the fluid medium, and a distal end having an expandable-contractible chamber for installation into suitable vessels or organs. The expandable-contractible chamber comprises a conduit element having a fluid-filled hollow wall defining a lumen. The conduit element has a first deformable inner-facing section approximate a proximal end of the conduit and a second deformable inner-facing section approximate a distal end of the conduit element. Controlled application of a pressure at a proximal end of the conduit element causes deformation of the conduit into the lumen at its distal end thereby occluding the flow of fluid medium through the catheter. Controlled release of the pressure releases deformation of the fluid-filled conduit at its distal end thereby unblocking the flow of the fluid medium through the catheter.

摘要： Methods and a system to unify reconstruction and motion estimation steps in first pass cardiac perfusion MRI include a global objective function that meets data consistency, spatial smoothness, motion and contrast dynamics constraints. The global objective decomposed into simpler sub-problems which include low pass filtering of a deformed object, TV shrinkage, analytical Fourier replacement and an l2 minimizing problem. A registration tool based on the local cross-correlation similarity measure and enabled to perform both rigid and flexile deformations, is applied. Registration parameters are tuned by rigid, semi rigid and flexible models at different stages of iterations. A system to perform the methods is also disclosed.
