  • Publication number: 20210403754
    Abstract: The purpose of the present invention is to provide a product, in particular, a coating material capable of preventing icing and/or snow accretion. This product includes a first oil component, a second oil component, and a first resin precursor, which is a precursor for a resin component. The first resin precursor including the first and second oil components is cured to form an oil-containing resin layer including the first and second oil components and the resin component. The second oil component constitutes a low-temperature phase-separable oil component that may be phase-separated from the first oil component to exude from the oil-containing resin layer when a temperature decreases to a predetermined value or lower.

  • Publication number: 20200160174
    Abstract: Big data, which is too massive to analyze instantly, could cause various problems, including threats to the security by terrorism and intellectual crimes hiding behind its huge volume and complexity. Using topological information as key unit to encode information, every single piece of information is converted into a topology or geometric shape and encoded in a clock without requiring software programming by a human. Each of the converted piece of information itself indicates an event, a decision, etc. that has its own significance/meaning. Geometric shapes integrate within their single decision time and again to find the intricate pattern of any event, including the above-mentioned threats.

  • Publication number: 20200160147
    Abstract: Artificial intelligence research is failing to produce true intelligence in spite of enormous resources. The reason is that programming is unavoidable for data processing and so there is no way to replace an user. In addition, because of data deluge problem, it is impossible to analyze all data as conventional information. Hardware inspired by prime metric is provided, where a metric of artificial intelligence is built in which unknown random events are linked as a changing geometric shape. All information is converted such that layered geometric shapes clocking in a pattern or event becomes unit of information, not insignificant bits. All complex events are considered as a single point to go ahead on building higher level geometric shapes as part of a time crystal following prime metric.
