ここ十数年の間に,カオス時系列の予測手法はずいぶん進展した.しかし,指数平滑法のような実務的に有用な簡便法で,カオス時系列を扱えるものは少ないようである.そこで本研究では,線形自己回帰モデルにダミー変数を加えた簡便的なカオス時系列の予測手法を考える.Forecasting method of chaos time series have been proceeded for this ten years.But, there is a few convenient methods for chaos time series like exponential smoothing.In this study,we examine convenient forecasting method for chaos time series that is liner autoregressive model adding dummy variables.

Three-dimensional real-space images of the carbon fiber (CF)/polymer composites were obtained by a high-contrast X-ray computerized tomography (CT). Since both CF and polymers do not include heavy atoms, CF has not been supposed to be suitable to X-ray CT observation. In this study, we used the X-ray CT apparatus which is designed to enhance the contrast of the materials consisting only of light-weight atoms. Besides the usage of the appropriate apparatus, the experimental conditions were found to be important : cutting the sample into a thin rod, and obtaining sufficient number of projections. In our case, we used 1mm × 1mm × 4mm sample, and 720 projections with 0.25 degree intervals in order to obtain the 3μm voxel resolution in the reconstructed three-dimensional images. Eventually, each CF in polystyrene was clearly visualized in three dimensions.

The purpose of this study was to investigate the relation of love styles in heterosexal intimate relationships and the size of interpersonal networks. One hundred and ninety-three female college students responded to a questionnaire asking about the six love styles based on Lee's theory (1977) and the size of interpersonal networks with male or female friends. Results showed (1) the network size of the students having a lover or a boyfriend was not smaller than that of the students who did not have such an intimate relationship (a mere friend or one-sided love), and (2) the score of Mania, a style of love, was negatively related to the network size with female (own sex) friends. These results suggest that although a heterosexal intimate relationship is not always closed or exclusive, it might become closed or exclusive when the romantic love feeling of Mania is too strong.
