The present invention is capable of accurately estimating the density of an object by measuring cosmic rays that are transmitted through the object. A spectrum acquiring unit acquires a first energy spectrum of first cosmic rays that arrive at a predetermined zenith angle without being transmitted through an object, and acquires a second energy spectrum on the basis of a measurement result of second cosmic rays that arrive at the predetermined zenith angle after being transmitted through the object. A spectrum comparison unit compares the first and second energy spectra to analyze the energy loss of the second cosmic rays due to the transmission through the object. An estimating unit calculates, on the basis of the energy loss analysis result, the amount of matter on a path through the object along which the second cosmic rays were transmitted, and calculates an estimated value of the density of the object by dividing the amount of matter by the length of the path.

The present disclosure describes a method for conditioning and preprocessing raw cosmic ray data to extract features and generate a binary string representing the inherent randomness in the data. Measurable characteristics of cosmic ray particles, such as arrival times and amplitudes, are processed to create random binary sequences.

In the GAN framework, the generator creates random sequences resembling the target distribution, which matches the entropy of the conditioned cosmic data. The discriminator evaluates the generated sequences by comparing them to the conditioned cosmic data and assigns a randomness score that characterizes the quality of the generated sequences. This adversarial process ensures the generation of high-quality random sequences that are statistically indistinguishable from the conditioned input data.

To uniformly induce nuclear reactions on the surface of a hydrogen-containing metal in room-temperature nuclear fusion.SOLUTION: In a case where the excitation time 1 / (F×A×V) is estimated when F is the flux density of high-energy excitation source particles such as cosmic rays, A is the capture coefficient of the hydrogen-containing metal for the excitation source particles, and V is the volume of crystal grains constituting the hydrogen-containing metal, the excitation time becomes more than one million years under present background neutron conditions on Earth for typical current grain sizes. Thus, only an extremely small portion of the entire material can undergo nuclear reactions, revealing the need for a fundamental solution. The most effective method is single crystallization or large-grain polycrystallization, which significantly improves the excitation time. Dramatic improvement is also achievable by artificially supplying high-energy particles to the hydrogen-containing metal using LC resonance type accelerators or the like.SELECTED DRAWING: Figure 9
