    摘要： A hybrid tissue scaffold is provided which comprises a porous primary scaffold having a plurality of pores and a porous secondary scaffold having a plurality of pores, wherein the secondary scaffold resides in the pores of the primary scaffold to provide a hybrid scaffold. The pores of the porous primary scaffold may have a pore size in a range of 0.50 mm to 5.0 mm, and the pores of the porous secondary scaffold may have a pore size in a range of 50 μm to 600 μm. The primary scaffold may provide 5% to 30% of a volume of the hybrid scaffold.

    摘要： A system and method for estimating location and motion of an object. An image of a ground surface is obtained and a first set of features is extracted from the image. A map database is searched for a second set of features that match the first set of features and a geo-location is retrieved from the map database, wherein the geo-location is associated with the second set of features. The location is estimated based on the retrieved geo-location. The motion of the object, such as distance travelled, path travelled and/or speed may be estimated in a similar manner by comparing the location of extracted features that are present in two or more images over a selected time period.

    摘要： A piston for a direct injection engine is provided, the piston having a bowl at an upper end, the bowl forming a portion of a combustion chamber. The bowl includes an inner surface that defines a volume configured to receive a fuel-air mixture, the inner surface of the bowl including a generally concave portion including a flat bottom surrounding a central protruding dome. The relatively flat bottom portion is bounded by two radial concave surface portions which are disposed below two convex separation features for the injected fuel spray. Such surface geometries may reduce soot and improve fuel-air mixing.
