Recently, several digital watermarking techniques have been proposed for hiding data in the frequency domain of moving image files to protect their copyrights. However, in order to detect the water marking sufficiently after heavy compression, it is necessary to insert the watermarking with strong intensity into a moving image, and this results in visible deterioration of the moving image. We previously proposed an authentication method using a discrete wavelet transform for a digital static image file. In contrast to digital watermarking, no additional information is inserted into the original static image in the previously proposed method, and the image is authenticated by features extracted by the wavelet transform and characteristic coding. In the present study, we developed an authentication method for a moving image by using the previously proposed method for astatic image and a newly proposed method for selecting several frames in the moving image. No additional information is inserted into the original moving image by the newly proposed method or into the original static image by the previously proposed method. The experimental results show that the proposed method has a high tolerance of authentication to both compressions and vicious attacks.

＜正＞This paper considers the problem of reducing the roundoff noise in two-dimensional separable-denominator digital filters using error *** error feedbacks are implemented with scaling factors in a two-dimensional separable-denominator digital filter implemented with minimum number of delay elements. For each error feedback,the optimal solution of coefficients is obtained in a closed form to minimize the noise variance at the filter *** illustrative example is given to demonstrate the validity of the proposed technique.

Recently, several digital watermarking techniques have been proposed for hiding data in the frequency domain of audio files in order to protect their copyrights. In general, there is a tradeoff between the quality of watermarked audio and the tolerance of watermarks to signal processing methods, such as compression. In previous research, we simultaneously improved the performance of both by developing a multipurpose optimization problem for deciding the positions of watermarks in the frequency domain of audio data and obtaining a near-optimum solution to the problem. This solution was obtained using a wavelet transform and a genetic algorithm. However, obtaining the near-optimum solution was very time consuming. To overcome this issue essentially, we have developed an authentication method for digital audio using a discrete wavelet transform. In contrast to digital watermarking, no additional information is inserted into the original audio by the proposed method, and the audio is authenticated using features extracted by the wavelet transform and characteristic coding in the proposed method. Accordingly, one can always use copyright-protected original audio. The experimental results show that the method has high tolerance of authentication to all types of MP3, AAC, and WMA compression. In addition, the processing time of the method is acceptable for every-day use.

We tested to use several compositions of a four-component-mixture R32/125/134a/600 as a refrigerant for replacing R22 in refrigeration system of refrigerated warehouses. R32, R125, and R134a are hydrofiuorocarbons and R600 is normal butane. The refrigeration hardware designed for a refrigerant of R22 can be used without any change or with very minor change. By using appropriate composition of the four-component refrigerant, existing refrigeration system can provide best performance because the adjusted properties of the refrigerant can somewhat compensate for the individual hardware problems. Practical operation test was done by using a refrigeration system of nominal cooling capacity of 30.2 kW with a 22 kW two-stage compressor which equipped for a 858 m refrigerated warehouse maintaining at -30 ℃. The pressure condition and the coefficient of performance of R32/125/134a/600 are similar to R22 from a theoretical viewpoint. The power consumption of R32/125/134a/600 was small enough or not to be worse than that in the case of using R22, which was confirmed from the actual test results.
