Abstract: A method of route construction of an unmanned aerial vehicle (UAV) network includes: obtaining transmission information of the UAV network; determining a relay set from the UAV network based on the transmission information; wherein, the relay set includes at least one UAV; determining environment state parameters according to the transmission information and the information of the relay set; inputting the environment state parameters into a Deep Q-Learning network (DQN) to obtain an accumulated reward corresponding to each UAV; and selecting a UAV with the largest accumulated reward as a target UAV. This disclosure also discloses a UAV and computer readable storage medium that can be used to construct routes for a UAV network.

Abstract: A multi-use cloth for cleaning and conditioning metal and non-metal objects includes a two-layer, three-layer or multi-layer structure. Each layer is made of material either capable of retaining an oil, aqueous solution, aqueous suspension or solid or capable of preventing penetration of an oil, aqueous solution, aqueous suspension or solid. In a three-layer or multi-layer cloth, the separation layer is affixed in between two layers having one or both layers embedded with an oil, aqueous solution, or aqueous suspension. In a two-layer cloth, the separation layer is affixed to one side of the layer that is embedded with an oil, aqueous solution or an aqueous suspension. The cloth is folded with the oil, or aqueous solution, or aqueous suspension embedded side on an inner side. A user's hand holds the outside of the cloth and no contamination from oil, aqueous solution, or aqueous suspension or solid occurs.

Abstract: A cleaning and conditioning cloth for an ice skate, including hockey and speed skates, as well as other objects, includes a rectangular body, or a body selected from one of other various shapes such as circle, square, and diamond, of cut-resistant, water-absorbent fabric and an oil impregnated fabric affixed to the approximate center of the cleaning and conditioning cloth body wherein the method includes the steps of holding the cleaning and conditioning cloth in one hand and the ice skate in the other, placing the blade of the ice skate in the middle of the oil impregnated fabric, and moving the ice skate and the cleaning and conditioning cloth relative to each other, so that the blade moves from the cleaning and conditioning cloth body to the oil impregnated fabric. The body and the oil impregnated fabric may be of various sizes.
