Methods, systems, and computer program products for hierarchical registration (102) between a blood vessel and tissue surface model (100) for a subject and a blood vessel and tissue surface image for the subject are disclosed. According to one method, hierarchical registration of a vascular model to a vascular image is provided. According to the method, a cascular model is mapped to a target image using a global rigid transformation to produce a global-rigid-transformed model. Piecewise rigid transformations are applied in a hierarchical manner to each vessel tree in the global-rigid-transformed model to perform a piecewise-rigid-transformed model. Piecewise deformable transformations are applied to branches in the vascular tree in the piecewise-transformed-model to produce a piecewise-deformable-transformed model.

An information processing system includes a stream getting section for getting a data stream representing a content and a recording processing section for generating output control information and writing the data stream and the output control information on a medium. The output control information defines an appropriate output method, which is compatible with the output format of the content, following a rule that defines what type of processing should be done according to the type of input source of the content and the output format of the content and in accordance with source related information on the input source of the content. By reference to the output control information, a device that is going to play back the content from this medium can output the content without considering its input source.

A virtual terrain architecture and computer program product for employing a geocentric coordinate system, using a tessellated three-dimensional shape for representing a celestial body, and mapping terrain data to the tessellated three-dimensional shape is disclosed. In one embodiment, the methodology begins with a seed polyhedron such as an ellipsoid model. The seed ellipsoid is preferably composed of a plurality of triangle primitives. After selection of the seed ellipsoid, the ellipsoid is subdivided using tessellation. Each triangular element is subdivided into four sub-elements which are also triangular in shape. As the elements are further subdivided, the triangles of the ellipsoid model create a sphere that is representative of the earth or other celestial body. Tessellation continues until a desired resolution is reached for each triangular element. Once a sphere has been substantially formed, terrain data is mapped to the triangular elements and the data is converted to geocentric coordinates and stored in a database. Each triangular element is separately indexed according to the triangular elements name. By creating a geocentric representation, the earth's curvature and polar regions can be accurately represented. By using a tessellation process, tiling for the geocentric coordinate system is achieved. Thus, the tiles can be paged as discrete elements.

The invention relates to a method for enhancing the surface of magnesium aluminium alloy by laser remelting, aiming at enhancement processing of the surfaces of magnesium aluminium alloy plates and magnesium aluminium alloy rods by the methods of flame spraying of alloyed powder and laser remelting. The method is characterized by cleansing the surface of the magnesium aluminium alloy, carrying out oxy-acetylene flame spraying on the alloyed powder, namely aluminium nickel alloy powder, nickel-chromium-boron-silicon-iron master alloy powder and neodymium powder, carrying out remelting and curing on the surface of the magnesium aluminium alloy on a laser processor, carrying out omnibearing radiation by laser beams according to trace curves set by computer programs so that a nickel base alloy layer is melted and cured on the surface of the magnesium aluminium alloy to form the alloy layer, therefore, the hardness of the surface of magnesium aluminium alloy is greatly improved by 8-10 times as high as that before processing, the wearing resistance and corrosion resistance of the surface of magnesium aluminium alloy are greatly improved respectively by 56% and 56.4%. The method has short process flow, easy realization, safety, stability and reliability and firm solid melting layer, is not easy to fall off and can enhance the surfaces of the magnesium aluminium alloys with various profiles.

A method, system and computer program of planning a dental prosthesis in a patient are disclosed, including steps, units or code segments for virtually planning a dental prosthesis. Envelope data is provided of an envelope guide, including data corresponding to a support surface for facial tissue, which is desired to result when the dental prosthesis is installed in the oral cavity of the patient. An outer envelope of a desired dental prosthesis in the oral cavity is simulated based on the envelope data. A desired dental restoration is provided and adjusted in a virtual environment relative to the simulated outer envelope, and dental prosthesis data is generated based on the adjusted desired dental restoration usable for producing the dental prosthesis.

Systems, methods, and computer program products are provided for ensuring coherency between user data in a client and their corresponding state in enterprise information systems (EIS) wherein data migrates and subscriptions change over time. A mobile business object (MBO) identifies an update to a subscription or a change in set membership in order to provide updates to a client device and EIS systems. Cached data is filtered for client device users who synchronize data they are interested in (i.e., subscribed to). In an embodiment, the method keeps track of set membership by remembering on a per remote identifier / business object basis the set membership for a parent business object. When set membership changes, the method sends delete notifications to the device to remove ex-members. The method recognizes common relationship types in a business scenario and handles reference-type relationships as well as containment-type relationships. The methods include key tracking and membership tracking.
