Tissue-engineered biomaterials have existed approximately 40 years as simple biomimetic structures. Replacement of human tissue with new tissue can be accomplished by generating replacements outside of the body or in situ in the body. In each case, the key elements are described as the tissue engineering triad of scaffolds, cells, and signals. Scaffolds can be produced synthetically or derived ...

Abstract It is largely assumed that conceptual engineering essentially about revising, introducing, or eliminating representational devices, in particular the intension and extension of words concepts. However, tying too closely to representations risky. Not everyone endorses notion representation as theoretically helpful even real. thinks concepts meanings should be understood terms representa...

Scanners operating on the optical principle are devices for recording physical geometry of bodies suitable non-contact measurement which work in visible light range. These use difference contrasts and strength reflected measurement, by using classic triangulation principle. This article focuses reverse engineering technologies scanning process.
