A wavelet-based watermark casting scheme and a blind watermark retrieval technique are investigated in this research. An adaptive watermark casting method is developed to first determine significant wavelet subbands and then select a couple of significant wavelet coefficients in these subbands to embed watermarks. A blind watermark retrieval technique that can detect the embedded watermark with...

objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...

This paper will present a simple, low cost orthotic device designed to be used in underserved areas of the world that is capable of achieving the sequential correction of clubfoot in the newborn that is currently managed almost universally utilizing Ponseti casting. Despite the widely acknowledged efficacy of the serial casting developed by Dr. Ponseti in the 1950s, there are circumstances wher...
