Fresnel lens type complex reflection system having a lens function more. Parallelization of nonlinear MHD plasma simulation abstract more. Information Processing. Mechanism of cold fusion more. As a cold fusion mechanism, a fracto-fusion was investigated by which reacting particles are accelerated by the electric field generated between the crack surfaces in a crystal and the beam fusion occurs.

By assuming the possible By assuming the possible magnitude of the potential difference the fusion rate and energy multiplication factor were calculated. These results are consistent with cold fusion experiments. On the basis of a simple model it is conjectured that necessary electric potential difference to accelerate particles can be generated even in a metal crystal with rather low resistivity, and it was concluded that the fracto-fusion mechanism can explain the cold fusion phenomena successfully.

History of Controlled Nuclear Fusion in Japan more. In Japan,Researches of controlled nuclear fusion were began almost fifty years ago by the researchers of astronomy,nuclear physics,elementary particle, cosmic ray,discharge,and welding. At that time,they discussed research systems and At that time,they discussed research systems and restricted the main objectives within basic study.

Since then,large scale devices were developed,and the international collaboration of research and development was promoted. The history of the researches of controlled nuclear fusion in Japan was presented. Tomographic approach to investigate the ionospheric disturbance possibly associated with the off the Pacific coast of Tohoku Earthquake more.

In this paper, neural network based tomography using GEONET data has been performed to investigate the fine structure possibly associated with the off the pacific coast of Tohoku Earthquake Mw9.

Although the possible ionospheric Although the possible ionospheric anomalies preceding large earthquakes have been reported by many researchers, a physical mechanism of the anomalies has not been clarified yet. To understand the mechanism, monitoring of three-dimensional distributions of ionospheric electron density is considered to be effective. As for the off the Pacific coast of Tohoku Earthquake, the significant enhancements are found in G Development and validation of neural network based ionospheric tomography more.

In order to investigate the dynamics of ionospheric phenomena, perform the 3-D ionospheric tomography is effective. However, it is the ill-posed inverse problem and reconstruction is difficult because of the small number of data. They have demonstrated few results in quiet conditions of ionosphere in Japan. Methods of improving the prediction of plasma horizontal and vertical positions are discussed for a neural network. Performance of the prediction is evaluated in terms of root mean square error between true and predicted positions RMS Performance of the prediction is evaluated in terms of root mean square error between true and predicted positions RMS error , and hitting ratio of up-and-down trend.

Input signals are chosen appropriately and the number of input steps are increased in order to improve the performance. Due to the former, the RMS error of the predictions of the horizontal and vertical positions is improved. The improvement of the hitting ratio is insignificant. Due to the latter, both the RMS error and the hitting ratio of the prediction of the horizontal position are improved, although the improvement of the RMS error and the hitting ratio of the prediction of the vertical position are insignificant, Using signals of calculating step and the difference between the signal at the calculating step and signals at past steps, the RMS error can be reduced.

Thus, in the field of optical quantum information processing, which is my specialty, we can enjoy the pleasure of experiencing the physical laws of the microscopic world of light, controlling them with engineering techniques, and creating new value. In the future, we will work on the development of optical quantum computers using our original approach and explore practical applications using the technology.
