Anomalous increases on heat capacity curves of each substance, which markedly disturb melting curves of the triple point, are observed at temperatures just below the triple point. In the case of equilibrium hydrogen, a reduction of the amount of the catalyst suppresses the anomalous increases and allows one to obtain more reliable melting curves of the triple point.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

The hybrid structure means that a GA has 2 structures. One is the most popular chromosome type GA. That is, chromosomes have binary type genes. The other one is real coded GA. The former is used for determining a function type automatically. The latter is used for determining the coefficient of the function, time delay in the system and combination of the functions automatically. Finally, in order to show the effectiveness of the proposed method, computer simulations were done. Furthermore, in the computer simulations, 2-kinds of systems are identified. One is the hammer stain model. The other is a complex model. From these simulation results, the effectiveness of the proposed method is cleared.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

With the proposed method of spatial filter velocimetry, the spatial distribution of image motion or global motion parameters can be estimated by using a large number of small spatial filters arranged regularly in the image plane. Global motion parameters, such as translation, rotation, and dilation, can be isolated, identified and measured by evaluating the frequency distribution of the outputs from the spatial filters along a closed circular contour in the image plane. Experiments were performed in order to maintain the size and position of the object's image by using a camera of which the attitude is controllable. The proposed system, composed of only a commercially available PC, exhibited good tracking performances with processing rate of 15 frames per second.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

Here, we assume that a complete state observation is taken at each random instant t/sub i/, 0 /spl les/ t/sub i/ /spl les/ N - 1 and consider the general situation that the increment intervals are independent, identically distributed random variables (i.i.d.r.v.s) with Erlang probabilistic distribution (type K). The simulation results show that the optimal control obtained from designing is applicable to both random and equally spaced sampling case. Simultaneously the more K value increases, the more optimal control law approaches the standard optimal control law of sampled-data systems.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

Generally speaking, atmospheric flights for plane changes of the Earth orbits save fuel and increase the final mass considerably, but the problem is the aerodynamic heating. The solutions obtained in this research show that the optimal thrust usage is sensitive to the magnitude of the heat rate limit and one should be careful to choose the limit value to design the thrust controller.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.
