The pneumatic capsule pipeline transportation is a method to transport various materials by utilizing differential pneumatic pressure. It has advantages over conventional methods (e.g., vertical transport using a lift in a shaft) in terms of safety and economical efficiency when it is applied to the deep radioactive waste disposal facilities (Hane, et al., 2002). In this paper, focusing attention on the safety and efficiency of transportation, we propose a concept of the comprehensive transportation system for the high-level radioactive wastes disposal facilities. By introducing a curved pipe section to the pipeline system, we show the applicability and practicability of the system for the facility by analytical study.

We present a perception model of ambiguous patterns based on the chaotic neural network and investigate the characteristics through computer simulations. The results induced by the chaotic activity are similar to those of psychophysical experiments and it is difficult for the stochastic activity to reproduce them in the same simple framework. Our demonstration suggests functional usefulness of the chaotic activity in perceptual systems even at higher cognitive levels. The perceptual alternation may be an inherent feature built in the chaotic neuron assembly., Comment: 10 pages, 9 figures, to be published in Neural Processing Letters
