The present disclosure relates to a method for producing graphite oxide and an apparatus therefor.

Method for manufacturing graphite oxide and apparatus therefor

Disclosed are a system for managing virtual private networks (VPNs) includes: terminals configured to transmit user data; a manager configured to transmit information for concealing networks and managing the VPNs; border gateways configured to decrypt the user data and perform a network address translation (NAT) procedure and a filtering procedure on the decrypted user data based on the information; and servers configured to receive the user data subjected to the NAT procedure and the filtering procedure, wherein the filtering procedure is a procedure discarding the user data to be transferred to the servers that are not allowed so as to allow the terminals to access only the allowed servers, the NAT procedure is a procedure changing an Internet protocol (IP) address used in a first network to an IP address used in a second network, and the first network and the second network are different networks.

System for managing virtual private network and method thereof

There is provided a method of localizing an object comprising projecting an object located on an object plane and a reference point corresponding thereto on a virtual viewable plane and an actual camera plane; estimating coordinates of the reference point; and prescribing a relationship between a location of the object and the coordinates of the reference point.

Method for object localization using visual images with reference coordinates

A method of recognizing a self location of an image acquisition device by acquiring an image of two or more reference objects is provided. The method of the present invention comprises setting an actual camera plane, two or more reference object planes, and two or more virtual viewable planes located between the actual camera plane and the reference object planes; projecting the reference objects to a corresponding one of the virtual viewable planes; calculating a distance between a viewing axis and the reference objects and a distance between the viewing axis and images on the actual camera plane, the images corresponding to the reference objects; and sensing the self location of the image acquisition device by using an orientation and a zoom factor of the image acquisition device and coordinates of the reference objects, wherein the zoom factor is a ratio of a length of the reference object plane and a distance between the reference object plane and the virtual viewable plane, and the actual camera plane, the virtual viewable plane, and the reference object plane are perpendicular to the viewing axis.
