Design information required for producing the test adapter card is output based on the selection result and the division result.

Abstract: A network apparatus connected with a first clock source and at least one second clock source is provided. The network apparatus includes a system clock, a slave port connected to the first clock source, at least one passive port connected to the at least one second clock source, and a processor that controls synchronization of the system clock. The processor determines, from the slave port, a first clock offset between the system clock and a clock of the first clock source. The processor determines, from the at least one passive port, at least one second clock offset between the system clock and at least one clock of the at least one second clock source. The processor determines a true clock offset based on the first clock offset and the at least one second clock offset and synchronizes the system clock using the true clock offset.

Abstract: Disclosed is a membrane surface modification method. The method is applicable to a variety of hydrophobic membranes by doping selected inorganic particles. One act of the method involves the in-situ embedment of the inorganic particles onto the membrane surface by dispersing the particles in a non-solvent bath for polymer precipitation. Further membrane surface modification can be achieved by hydrothermally growing new inorganic phase on the embedded particles. The embedment of particles is for the subsequent phase growth.
