In this paper, we present the comparison of history of measurement displacement and numerical result of displacement by finite element analysis on concrete surface in hammering test. The rectangular concrete test piece was employed as the experimental model and the numerical one, and the analysis for the three dimensional oscillation was carried out. The Galerkin procedure and the Newmark β method were applied to discretize the finite element equation for the three-dimensional oscillation in space and time, respectively.
In this paper, we present an evaluation method of comfortable vehicle using measurement data of brain wave. In general, the comfortable car is evaluated by the actual driving test, and the result depends on the driver. To solve this problem, the measured brain wave is introduced to numerically evaluate the comfortable car. The measured brain wave is evaluated by using the face scale score.
In this paper, we present the estimation analysis of flow field in wave tank based on the ensemble Kalman filter FEM. The ensemble Kalman filter FEM is the fusion method of the ensemble Kalman filter theory and the FEM, and the characteristic of this method is the estimation of flow field can be carried out considering the observed physical variables. In this study, the observed water elevation is utilized for the flow estimation analysis. As the governing equation, the shallow water equation is introduced, and the “Stream Upwind Petrov Gelerkin method” (“SUPG method”) is employed to discretize the governing equation.
In this paper, we present the result of vibration test using the automobile chassis parts fabricated by 3D printer based on the topology optimization results. In the topology optimization analysis, the strain energy minimization analysis was carried out, and the optimized shapes were obtained by changing the initial density conditions. The shapes were fabricated by 3D printer, and the practical vibration tests were performed. Consequently, it was found that same tendency can be obtained between numerical and experimental results.
The study presents the following experiments: the difference between silent and oral reading concerning sentence comprehension; the effect on learners who make phonological encoding during silent reading; and the difference between them caused by involuntary gestures. Through the experiments, phonological encoding was examined through the effect of articulatory suppression. The participants were asked to read sentences under six different conditions: silent with no-tapping & no-gestures; silent with gestures; silent with tapping; oral with no-tapping & no-gestures; oral with gestures; oral with tapping; and articulatory-suppression. Experiment 1 showed no difference between silent and oral reading concerning sentence comprehension. Experiment 2 indicated that phonological encoding during silent reading may improve comprehension of both silent and oral reading. Experiment 3 was designed to test whether non-iconic movements facilitate the retrieval of sentence comprehension during oral reading. Results showed gestural learners’ comprehension improved with gestures. However, non-gestural learners’ comprehension was weaker when required to gesture than when only reading aloud.
A mathematical tablet called sangaku was dedicated to the Kinpujinjya—the shinto shrine in Nagaoka in 1795. The sangaku is a historical work that shows the wasan—the traditional Japanese mathematics in the Edo period of Japan. However, this sangaku does not currently exist and remains only in the literature. Then, we try to reproduce the sangaku through the drawing by computer. The sangaku is constituted of two problems. We infer the solutions at the time.
