Abstract: The present disclosure provides a database server allocation method and apparatus. The database server allocation method may be performed by an allocation server interfaced with a plurality of database servers each of which collects data from one or more data generators. The method includes: allocating an initial database server for each data generator; receiving information on an amount of data generated by each data generator from the plurality of database servers; analyzing the amount of the data generated by each data generator to determine a data generation pattern for each data generator; and grouping the data generators according to the data generation pattern for each data generator and reallocating a new database server for each data generator.

Abstract: There is provided a method performed by a system for obtaining a relative location of an anchor-free UWB-based node. The method includes obtaining relative distances between a plurality of nodes based on UWB sensor values between the nodes, constructing a relative coordinate system having a center node of the plurality of nodes as a base, and calculating coordinate values of other nodes in the relative coordinate system. The constructing of the relative coordinate system having the center node of the plurality of nodes as a base includes constructing the relative coordinate system based on a relative distance between the center node and another node and absolute values of y axis values.

Abstract: A method for controlling movement of a real object by using an intelligent agent trained in a virtual environment may comprise determining an initial action value for an initial state of the real object by using an intelligent agent trained in a virtual object simulating the real object in a virtual environment; obtaining a first state as a next state of the initial state by inputting the initial action value to the real object; determining a first action value for the first state by using the intelligent agent; obtaining a second action value by correcting the first action value so that a state change of the real object coincides with a state change of the virtual object; and inputting the second action value to the real object.
