タイトル: Decomposition of mechanical stress effect on the magnetic property of silicon steel sheet著者: Shimizu, H.; Marumo, Y.; Mishima, Y.; Matsuo, T.抄録: A principal stress decomposition method was examined and compared with the equivalent stress theory to evaluate the stress-dependent magnetic properties of nonoriented silicon steel. A physical magnetization model, the multidomain particle model, was used to simulate the stress dependence of the magnetic properties by applying mechanical stress in different directions relative to the magnetic field direction. Experimental and computational tests show that even though the principal stress decomposition method provides a reasonable evaluation of the stress-dependent properties in the stress direction, it fails to accurately predict the properties in the perpendicular direction. To improve the prediction accuracy, a modified decomposition method is proposed, which gives a reasonable evaluation of the stress dependence of BH ...

タイトル: Grain-scale investigation of swash zone sediment transport on a gravel beach using DEM-MPS coupled scheme著者: Tazaki, Takumi; Harada, Eiji; Gotoh, Hitoshi抄録: Sediment transport in the swash zone directly affects beach changes such as shoreline recession; thus, detailed understandings of sediment transport mechanisms are necessary to accurately estimate the short-time scales sediment transport rate. However, these detailed mechanisms under runup waves have not been elucidated because of the complex solid-gas-liquid multiphase turbulence flow. In this study, we attempt to numerically investigate the sediment grain-scale mechanism to overcome the shortcomings of experimental measurements and the free surface treatment in many numerical simulations. The gravel transport process on a sloped beach under regular waves was simulated using a 2D coupled model of the discrete element method (DEM) and a modified moving particle semi-implicit (MPS) method; a sub-model was built ...

タイトル: Horses’ Social Evaluation of Human Third-Party Interactions著者: Sugimoto, Takuto; Hirata, Satoshi抄録: Humans evaluate others by observing their interactions with third parties that are not directly related to the observers’ interests. Such third-party evaluations have not been well-studied in nonhuman animals. In this study, we investigated whether horses socially evaluate humans based on their third-party interactions. We used a helping paradigm similar to that used in earlier studies with dogs and cats: that is, the horses watched as an experimenter (attempter) tried unsuccessfully to open a container in order to remove an object and then asked another actor on his right (i.e., helper/non-helper) for help. The actor either helped the attempter or refused the request by turning away. After this interaction, the attempter repeated the same procedure with another actor on his left. The actor on the left played the opposite role to the actor on the right. After th ...
