The reaction of K2[PtCl4] with pyrimidine-2-thiol (pymSH) was reinvestigated. Among the possible four isomers, the major product was the cis isomer of [PtIII2Cl2(pymS)4] (1). The Pt(II) complex cis-[Pt2(pymS)4] (2) was prepared by the addition of NaO

We propose a highly efficient arithmetic coding method for bi-level images. In this paper, our main interest lies in generating bi-level images suitable for arithmetic coding. Hence, a bi-level quantizer is integrated in our coder. Bi-level images ar

An optimal pixel assignment model for objective quality measure of halftone images has been developed. The model is based on the smallest units for tone reproduction and edge reproduction. The correlation of the reproduction error between an original

In a description of a data by using arithmetic coding, coding parameters are estimated for each markov state independently. However, markov states are not completely uncorrelated in many cases. By utilizing the correlation, we can decrease estimation

We propose a highly efficient arithmetic coding method for document images. In the arithmetic coding, series of symbols to be coded are mapped on a coordinate of a numerical line segment which corresponds to a coding space. By using a priori knowledg

We propose an arithmetic coding model for color images processed by the error diffusion. The error diffusion is a dynamic thresholding method of high quality tone rendering. However, there is a problem that probability model of conventional compressi

The third-order optical nonlinearities of silicon 2,3-naphthalocyanine dioctyloxide (SiNc) were measured by a femtosecond degenerate four-wave mixing technique under resonant conditions. The electronic second molecular hyperpolarizability γe of SiNc
