What about the good character on the animation? In our past research work, we created a three-dimensional character animation using motion capture data. And then, we tried to make the software to change the three-dimensional animation character into the two-dimensional animation character with a kind of animation movement. The two-dimensional character animation has the different style of movement in comparison with the three-dimensional character animation. In this work, we didn't learn to hope for the audience to be in the character moving that was made by the operation which followed a physical simulation. Then, we got an idea when it was necessary to define the good character moving on the animation what we developed the anime creating system helped by the computer. In this paper, a technique of movement analysis of the animation is described.

"In 1925 Rosenthal and White introduced a bromosulfophthalein (BSP) dye retention test as a sensitive indicator of liver function. Even now it is regared as one of the most sensitive agents for the detection of non-icteric liver disease (liver cirrhosis, early stage of acute-hepatitis and hepatic tumor). BSP accumulates in the liver cells, conjugates with glutathione and is excreted into the bile. Therefore, a disorder in its excretion is due to a disturbance of one of these processes. Since bilirubin and BSP compete for uptake by the liver and increased serum bilirubin interferes with the colorimetric determination of BSP, it has been considered that BSP test is inappropriate for the differential diagnosis of jaundice conditions. It has been generally said that when jaundice is present, the BSP test is useless and should not be performed. In 1955, Taplin et al. labeled rose bengal, a dye similarly metabolized in the liver as BSP, with 131I and measured the hepatic excretion of this dye by external monitoring. Laster, Blahd et al. applied this method to the determination of the peripheral pool, succeeding in the diagnosis of chronic and subacute hepatic diseases without colorimetry. In 1968, Yamada, Taplin et al. suggested the possibility of differentiating so-called medical jaundice from surgical jaundice by scanning the subjects during 24 to 48 hours following intravenous injection of 131I-labeled rose bengal. As mentioned before, many authorities hold the opinion that BSP is not proper for the differential diagnosis of jaundice states. Some have tried to diagnose biliary tract obstruction by a malignant tumor by measuring BSP excretion into duodenal fluid and others by quantitating changes in serum levels of conjugated and free BSP. Furthermore, Burton et al. reported that in patients with extrahepatic obstructive jaundice, BSP retention was observed for 24 days after its administration. From a consideration of all these finding we came to a conclusion that the differential diagnosis of various jaundice states, (medical, surgical and constitutional) is possible by sequential scanning with radioisotope-labeled BSP, as with rose bengal, in accordance with procedures described by Yamada, Taplin et al. The evidence suggested that labeled BSP might make a more important contribution than rose bengal. "

Agricultural crawler tractors that have adopted rubber crawlers are common because of the reduced effects of machine and road surface vibrations. This study targets the oscillating crawler unit that contains a special mechanism in which the unit oscillates around a hitch point that is set separately from the drive axis of the drive sprocket. Half-tracked tractors equipped with an oscillating crawler units have better stability on uneven ground than wheel type tractors, which respond directly to a concavo-convex surface. However, the crawler tension fluctuates according to the variation in the perimeter of the crawler unit when this unit travels on a concavo-convex surface because the hitch point of the oscillating frame is set separately from the drive axis of the drive sprocket. It is suggested that this fluctuation in the crawler tension influences driving performance. Moreover, driving performance factors (e.g., frame oscillation, traction, and drive torque) might be optimized by actively controlling the crawler tension. It is also generally known that some problems such as damage to and dropping of the rubber crawler have arisen during operation because of soil and stones sticking to the track rollers and the tension fluctuations of the crawler. These problems might be also obviated by actively controlling the crawler tension. We have proposed a driving simulation model for half-tracked tractors that has the ability to express the fluctuation in the crawler tension. However, this driving simulation is not verified, because it is very difficult to measure the crawler tension while driving, and little has been reported on the measurement of crawler tension. Therefore, this study aims to propose a measurement method for crawler tension fluctuation, which focuses on the inner structure of the rubber crawler. A fundamental experiment with a test piece cut out of a rubber crawler was carried out to evaluate the effectiveness of the proposed tension measurement, which uses steel cords arranged inner the rubber crawler. In conclusion, it has been demonstrated the possibility for stable measurement of crawler tension.

Development of Sensing Device for Plant Conditions Utilizing Lazer Speckle Method

Japanese smart-agriculture (new agriculture for labor-saving and high-quality products by utilizing advanced technology such as a robot technology and ICT) has been promoted by Ministry of Agriculture, Forestry and Fisheries. For Japanese smart-agriculture, several ambient conditions, such as temperature, humidity, soil moisture, CO₂ concentration, and others are available to optimize the cultivation. To get higher quality than ever, it’s needed to utilize the information of plant conditions such as photosynthetic ability, transpiration rate and respiration activity. However, there are no devices sensing them in the field and at a low price. We focus on laser speckle method (LS) which can detect microscopic motion of the target object. The interference pattern of the light which scattered and reflected on the surface or the inside, was created on the image sensor when coherent light such as a laser is irradiated the target object. This pattern is generally referred to as “Speckle”. It has been reported that the speckle pattern would be also depended on the structure of surface or inner parts of the target object. LS would be able to distinguish the movement reflected physiological phenomenon of plant by analyzing speckle images. In other words, it could obtain the information of plant conditions utilizing LS. The ultimate goal of this study is to develop a new and inexpensive device utilizing LS for sensing plant conditions. Some techniques for analyzing fluctuation of the speckle pattern have been proposed. Fujii method (FM) and Generalized difference method (GD) were used in this study. Both are analysis method for speckle images to quantify the luminance fluctuation of each pixel on consecutive images. The characteristics of the former are that analysis speed is relatively fast, and it could also enable to analyze in low brightness. The latter would clearly distinguish large fluctuation parts. In this experiment of adding the water stress to the plant samples, it was examined whether the water stress can be detected by using LS or not, and which analysis method is suitable to detect plant conditions. Speckle images were obtained from the main vein and the mesophyll cells of the sample soybean’s leaf, under two conditions; water stress and no treatment. Water stress was added to sample soybean by cutting leafstalk. The speckle images were taken at every hour from 7 am to 7 pm. As results, it was confirmed that it is capable to detect the water stress by analyzing speckle images. Comparing results of water stress and no treatment, increasing of water stress after cutting leafstalk was detected by both FM and GD, and GD was able to detect earlier and accurately than FM did. And it would be required to improve better measurement conditions and analysis method from now on.
