Journal of Dental Research, Dental Clinics, Dental Prospects, 2011 Background and aims. One of the major problems of all-ceramic restorations is their probable fracture under occlusal force. The aim of the present in vitro study was to compare the effect of two marginal designs (chamfer and deep chamfer) on the ...

Optimum design of chamfer distance transforms [PDF]
IEEE Transactions on Image Processing, 1998 The distance transform has found many applications in image analysis. Chamfer distance transforms are a class of discrete algorithms that offer a good approximation to the desired Euclidean distance transform at a lower computational cost. They can also give integer-valued distances that are more suitable for several digital image processing tasks. The

Comparative Studies on a Chamfer Technology and a Convex Roll Technology During the Soft Reduction Process [PDF]
Archives of Metallurgy and Materials, 2021 To comprehensively investigate the diversity of a chamfer technology and a convex roll technology under the same soft reduction process (i.e., section size, reduction amount, casting speed and solid fraction), a three-dimensional mechanical model was ...
