Abstract: A ship weighing system and a weighing method thereof include a collection module, a computing server, a wireless router, a display control terminal, and a network switch, which are installed in the ship. The collection module synchronously collects water level data of a stern and trim angle data of a front portion, a middle portion, and a rear portion of the ship. The computing server respectively calculates, based on the water level data collected by the collection module, an accumulated volume of the ship below a slice section parallel to a bottom plane of the ship corresponding to the water level data and a volume of a trim wedge formed by the slice section and an actual horizontal plane. The computing server combines results and corrects a volume of a vertical arch wedge in the middle portion of the ship to obtain a displacement volume of the ship.

Abstract: The existence of physicochemical variables in semiconductor components, such as the edge effect, the ion implantation, the surface state effect, and the variation in charge carrier mobility, is exploited in a method for manufacturing random serial number for integrated circuits. The physicochemical variables are measured with a high gain amplification circuit and then converted into digital signal. Owing to the randomness of variation of the measured physicochemical variables in semiconductor components, multiple random serial numbers are generated by using multiple amplification circuit units.
