4-Chloro-3,5-dioxaphosphacyclohepta[2,1-;3,4-']dinaphthalene (BINOL-PCl) was found to be an efficient, bulky and selective reagent for the transformation of symmetric and asymmetric benzoins to the corresponding benziles at 0 °C to room temperature under nitrogen atmosphere in good yield.

Huang presented a trade-off problem, taking both product quality and process adjustment cost into account, to determine the optimum parameters (i.e., the process mean and process variance) of the input characteristic in the transformation model. In Huang’s transformation model, the input characteristic, x, is assumed to be normally distributed and the output characteristic, y, is nominal-the-be...

This paper proposes a transformation scheme for rendering the asymmetric watermarking technique into its asymmetric version. The asymmetric technique uses secret watermark as private key and public watermark as public key. The public watermark has a normal distribution and the private watermark is a linear combination of the public watermark and a secret sequence. The detection process is imple...
