A thin film superconducting wire with a copper plating thin film produced on a surface of a laminated structure is inferior in bending properties to a thin film superconducting wire having no copper plating thin film. During a centralized short period, each terminal sends a probe message including a predefined sequence to a network device and the network device estimates the channel characteristics for each sub-carrier with respect to each terminal by estimating the received probe message. \u201c2\u201d is the minimum bet amount which can be specified in the high BET image. Other attributes can be used as well, whether based on the user’s personal driving data or driving data aggregated from a number of users. Hydraulic fluid can be added to the container via the conduit up to the level of the opening of the conduit.
