    Abstract: A method of manufacturing new materials for a printed circuit board and Low-Earth Orbit (LEO) spacecraft is provided. The present invention includes dinitro, diamine, various phosphorous-containing polyimides and polyamides, and synthesizing methods thereof. The polymers of the embodiment of present invention exhibit good flame retardancy, high glass transition temperature, good mechanical properties and superior oxygen resistance, so they are good materials for Low-Earth Orbit applications. Besides, these polymers can also be used as matrix for halogen-free flexible printed circuit board.

    Abstract: A method and system for detecting an insufficient coverage location in a mobile network is provided to detect the insufficient coverage location in a systematic and efficient way. The method generates a corresponding cell list for a registered address of a subscriber of the mobile network, where the cell list comprises at least one cell that potentially covers the registered address. Next, the call detail record (CDR) entries associated with the cell list are extracted. Then, it is determined whether the registered address is an insufficient coverage location of the mobile network according to the error codes included in the extracted CDR entries.
