Abstract: The present disclosure provides a method for preparing lithium iron phosphate from ferric hydroxyphosphate, including: purifying ferrous sulfate to form a ferrous sulfate solution, adding hydrogen peroxide, phosphoric acid, an ammonium dihydrogen phosphate solution and ammonia water into the ferrous sulfate solution and then reacting to form a mixed slurry, holding the mixed slurry at a temperature for a period of time, and then washing with water and subjecting to press filtration to form ferric hydroxyphosphate precursors with different iron-phosphorus ratios; then flash drying, sintering at a high temperature, and pulverizing to obtain ferric hydroxyphosphate precursors with different iron-phosphorus ratios and different specific surface areas.

Abstract: The disclosed technology teaches facilitate User and Entity Behavior Analytics (UEBA) by classifying a file being transferred as encrypted or not. The technology involves monitoring movement of a files by a user over a wide area network, detecting file encryption for the files using a trained classifier, wherein the detecting includes processing by the classifier some or all of the following features extracted from each of the files: a chi-square randomness test; an arithmetic mean test; a serial correlation coefficient test; a Monte Carlo-Pi test; and a Shannon entropy test, counting a number of the encrypted files moved by the user in a predetermined period, comparing a predetermined maximum number of encrypted files allowed in the predetermined period to the count of the encrypted files moved by the user and detecting that the user has moved more encrypted files than the predetermined maximum number, and generating an alert.

Abstract: A laminated shielding inductor includes a laminated body, an internal coil, and a shielding cover; the laminated body includes a plurality of insulator layers; shielding conductor through grooves which are located at the periphery of the internal coil are formed in the plurality of insulator layers; shielding conductors are arranged in the shielding conductor through grooves, are electrically and mutually connected and jointly form a shielding conductor laminated layer; a shielding conductor upper layer and a shielding conductor lower layer are respectively arranged above and below the internal coil; and the shielding conductor laminated layer, the shielding conductor upper layer and the shielding conductor lower layer are closed to form the shielding cover. Thus, high shielding effect of the laminated chip inductor can be realized, external radiation of the laminated chip inductor is effectively reduced, and the reliability of a circuit system is improved.
