    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.

    Abstract: An active-hydrogen-containing (carboxyl or hydroxyl) phosphorus compound is provided. An epoxy resin semi-thermoset formed by bonding the phosphorus compound to an epoxy group is also provided. A flame-retardant epoxy resin thermoset is formed after reacting the epoxy resin semi-thermoset with a curing agent. The epoxy resin thermoset possesses excellent flame retardancy, heat stability, and high glass transition temperature (Tg), does not produce toxic and corrosive fumes during combustion, and thus is an environmentally friendly flame-retardant material.

    Abstract: Processes of synthesizing aromatic amine-based benzoxazine resins are disclosed. The processes provide new routes for synthesizing benzoxazine from aromatic diamines or multifunctional aromatic amines that may solve the problem of insoluble products resulted from the condensation of hydroxymethylamine with amine by using aromatic diamine, phenol and formaldehyde as a raw materials.
