Abstract: The present disclosure relates to the technical field of nut-derived fruit oil preparation, in particular to a method for extracting palmitoleic acid from Macadamia integrifolia and use thereof. In the method for extracting palmitoleic acid from Macadamia integrifolia, a fruit oil of the Macadamia integrifolia is purified by vacuum distillation, and an antioxidant is added during the vacuum distillation. A preparation method of the antioxidant includes the following steps: extracting a pulverized Macadamia integrifolia green peel using ethanol by heat reflux to obtain a green peel extract; extracting the green peel extract using petroleum ether, and then using ethyl acetate; collecting an ethyl acetate layer to obtain the antioxidant. The method can avoid easy oxidization and deterioration of oil during extracting and enriching the palmitoleic acid, and can enrich the palmitoleic acid in the fruit oil of the Macadamia integrifolia by not less than 3 times.

Abstract: A model inversion-based iterative learning control method for a printer and a printer system. An error of a desired trajectory and an actual displacement of a printing paper and an error of a reference input and an actual displacement of a motor are considered at the same time to construct an iterative learning control model for the printer based on an inversion model, so as to iteratively modify an error failing to meet requirements.

Each data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective data packet. Data are then assigned to the data length fields of the sequence of data packets according to a second data format. The electronic device encrypts the sequence of data packets including the assigned data. The encrypted data packets are then sent to a receiver device that is communicatively coupled to the electronic device via a wireless network. The receiver device is configured to retrieve the assigned data from the data length fields of the data packets according to the first and second data formats and perform operations in accordance with the retrieved data.
