To obtain the fairing surface model of the loss part of detective skull rapidly, a new modeling method on skull defect repair is proposed in this paper. This method is to adopt the surface reconstruction algorithm to construct the local model of defective skull based on the sub-pixel cube model. The hole’s feature on the surface is automatically(More)
The structure of a tissue engineering scaffold plays an important role in modulating tissue growth. A novel gelatin-chitosan (Gel-Cs) scaffold with a unique structure produced by three-dimensional printing (3DP) technology combining with vacuum freeze-drying has been developed for tissue-engineering applications. The scaffold composed of overall(More)
This paper considers the stabilization of planar switched linear control systems. First, a structure property of not completely controllable pair (A, b) is revealed. Based on it, a simply verifiable, necessary and sufficient condition for the planar switched linear control system to be feedback stabilizable, is presented under the assumption that the(More)
Because web service function is continually strengthened, and web service quantity increases rapidly, it is urgent to solve the problem on automatic service matching and composition to meet service request. The service matching algorithm for bionic manufacturing domain-specific ontology is proposed in the paper. For this algorithm, the semantic similarity(More)
A combined method of tricalcium phosphate (TCP) scaffold production, which comprised negative mold and scaffold fabrication, was reported in this study. The negative mold structure was designed by computer and fabricated by fused deposition modeling (FDM) technology, while the TCP scaffold was produced by freeze-drying technology under different prefreezing(More)
