Aichi Prefectural University is a public university located in the city of Nagakute, Aichi, Japan. There is a campus in Moriyama-ku, Nagoya which is for the nursing school, namely Aichi Prefectural College of Nursing & Health. The predecessor of the school was founded in 1947, and it was chartered as a university in 1966. Wikipedia.

A stochastic process describes evolutional random phenomena towards future. Corresponding with this direction, there will be a process describing, as it were, backward evolution from future to present. The dual process is a realization of this fact. We restrict our attention to Gaussian processes for which multiple Markov property is well investigated. This property expresses way of dependence of involved randomness as time goes by. We can therefore expect that such a process with multiple Markov property would present an exact form of the dual process. We shall show that having defined generalized Gaussian process with multiple Markov property, we can construct the dual process satisfying the properties that we claim. The analysis for this can be done in the space of Hida distributions. © 2010 World Scientific Publishing Company. Source

Label-equivalence-based connected-component labeling algorithms complete labeling in two or more raster scans. In the first scan, each foreground pixel is assigned a provisional label, and label equivalences between provisional labels are recorded. For doing this task, all conventional algorithms use the same mask that consists of four processed neighbor pixels to process every foreground pixel. This paper presents a simple yet efficient first-scan method for label-equivalence-based labeling algorithms. In our method, foreground pixels following a background pixel and those following a foreground pixel are processed in a different way. By use of this idea, the pixel followed by the current foreground pixel can be removed from the mask. In other words, the mask used in our method consists of three processed neighbor pixels. Thus, for processing a foreground pixel, the average number of times for checking the processed neighbor pixels in the first scan is reduced from 2.25 to 1.75. Because the current foreground pixel following a background pixel or a foreground pixel can be known without any additional computing cost, our method is efficient for any image that contains at least one foreground pixel. Experimental results demonstrated that our method is effective for improving the efficiency of label-equivalence-based labeling algorithms. © 2009. Source

We derive some properties of minimum-error measurements for mixed quantum state signals where a density operator itself has a certain symmetry. In the first case, we show that if there exists a regular normal operator that commutes with each density operator of mixed state signals, then there exists an optimal measurement that consists of detection operators expressed as the direct sum of positive operators with supports in the eigenspaces of the regular normal operator. In the second case, we show that for abelian geometrically uniform state signals, if a matrix which represents one of the signals in a certain basis has all real elements, then the matrix which represents the corresponding detection operator of an optimal measurement in that basis also has all real elements. In addition, we discuss some examples of applications of these properties and derive analytical solutions of optimal measurements for special cases. © 2011 IEEE. Source

This article deals with the critical history of German and Japanese psychiatrists who dreamed of a 'German world' that would cross borders. It analyses their discourse, not only by looking at their biographical backgrounds, but also by examining them in a wider context linked to German academic predominance and cultural propaganda before World War II. By focusing on Wilhelm Stieda, Wilhelm Weygandt and Kure Shuzo, the article shows that the positive evaluation of Japanese psychiatry by the two Germans encouraged Kure, who was eager to modernize the treatment of and institutions for the mentally ill in Japan. Their statements on Japanese psychiatry reflect their ideological and historical framework, with reference to national/ethnic identity, academic position, and the relationship between Germany and Japan. © The Author(s) 2013.

Traffic fatalities and injuries in Japan have declined for twelve years by the comprehensive counter-measure for the reduction of traffic accidents. The efforts include enhancement of vehicle safety performance in both passive and preventive safety area. With regard to passive safety, major reduction effect was brought by airbag system, seat belt and crashworthiness of vehicle. For further reduction of the traffic accident, preventive safety may play more important role. Recently driver's psychosomatic state adaptive driving support safety system has been highlighted to reduce the traffic accident. For that reason reduction effect of psychosomatic adaptive safety function should be clarified to foster its penetration into the market. Statistical analysis of the traffic incident is highly expected to evaluate the reduction effect of the traffic accident of psychosomatic adaptive safety function. To execute the challenge, this study introduced Internet survey by delivering questionnaires to respondents. From the analysis of the collected answer, major psychosomatic state of driver is hasty and distraction. As a first step this study focused driver's distraction, which may cause severe traffic accidents. By using pattern recognition, the detection accuracy of driver's distraction was acquired. The reduction effect of the driver's distraction in the traffic accident was estimated by referring the reduction rate of both ASV (Advanced Safety Vehicle) and Intelligent Transportation Systems. © 2014 IEEE.
