A communication scheme for improving the performance of communications utilizing the transport layer connection provided via a radio network, by enabling a control of the transport layer connection according to the radio communication state and property of the radio terminal, without changing implementation of the transport layer of a terminal connected to a wire network. The thermal sensor and image capture devices are usable to help determine whether there is a failure or potential failure of a component of a wheel set by detecting, measuring andor comparing a temperature of various portions of the wheel set. The middle portion is located between the first intermediate portion and the second intermediate portion, and the first end is adapted to fit inside a proximal connector-receiving portion, and the second end is adapted to fit inside a distal connector-receiving portion. Further, preferably, the print data corresponding to the defective nozzle is sequentially distributed between data corresponding to two adjacent normal nozzles. A tension device coupled to the recovery line can absorb forces associated with the impact of the aircraft on the recovery line. The techniques for creating a test database instance enable database testing to proceed without impacting other organization’s access to their data in the database or corrupting an organization’s data.
