Abstract: A method for preparing metal oxide and ceramic oxide nano- and microparticulate materials is described herein. The method comprises irradiating a precursor material with high energy pulsed-light flashes in an oxygen-containing atmosphere. The precursor materials comprise thin films, fibers, or particles of subnano-, nano-, or microscale dimension, which are composed of metal ions dispersed in an amorphous or partially crystalline polymer matrix in a ratio necessary to form target metal oxide or ceramic oxide when reacted with oxygen (i.e., the precursor material does not include any metal oxide phase). The irradiation of the precursor material in an oxygen-containing atmosphere decomposes and removes the polymers and anions from the precursor, and also oxidizes the metal ions within the precursor materials to form metal oxide or ceramic oxide particulates.

The method includes: acquiring an image containing a target object or a target scene; generating simulated image examples for the acquired image, wherein the simulated image examples have adversarial effects on a deep learning algorithm in a target machine vision system; optimizing the generated simulated image examples to obtain an optimal adversarial example and corresponding adversarial parameters; and injecting the adversarial parameters into an inertial sensor of the target machine vision system in a manner of an acoustic wave, such that the adversarial parameters are used as sensor readings that will cause an image stabilization module in the target machine vision system to operate to generate particular blurry patterns in a generated real-world image so as to generate an image adversarial example in a physical world.

Abstract: A system for fabricating anisotropic magnetic nanowire composites includes a chamber for containing an ionic fluid. A hole in a wall of the chamber allows for the ionic fluid to be in contact with a porous template outside of the chamber, and a cathode and an anode provide an electric field across the ionic fluid and porous template. The electric field causes ionic materials in the ionic fluid to migrate into the pores of the porous template, therefore plating nanowires in the porous template. Constant distances and positions of the anode, cathode, a reference probe, and a stirring element allow for the fabrication of longer, more uniform nanowires, and for the generation of consistent magnetic nanowire composites across multiple fabrication sessions.
