Abstract:
Provided herein are a multi smartphone and a method of controlling the same. The multi smartphone includes a display part configured to output a screen when an input signal is sensed; a memory part configured to store a plurality of operating systems (OSs) which are operated differently based on a time at which the input signal is sensed, a place at which the input signal is input, or a user who inputs the input signal; and a control part configured to perform control such that at least one OS of the plurality of OSs is selected and operated based on any one of a time at which the input signal is sensed, the place at which the input signal is input, and the user who inputs the input signal when the input signal is sensed.
Abstract:
Disclosed is a method for hole-filling in 3D models. The method includes extracting static background information from a current frame of an input image and extracting virtual static background information using the static background information, warping a color image and a depth map of the current frame to acquire a virtual image and a virtual depth map, and labeling a hole area formed in the virtual depth map to extract local background information, performing a first hole-filling onto the virtual image and the virtual depth map using a similarity between the virtual static background information and the local background information, and performing a second hole-filling with respect to remaining holes after the first hole-filling in a manner of an exemplar-based in-painting method to which a priority function including a depth term is applied.
Abstract:
A power converter for a fuel cell is provided. The power converter includes a boost converter connected to the fuel cell and configured to control a load voltage at a predetermined magnitude in a normal operation mode and to induce an output response by applying a predetermined perturbation current to the fuel cell in a diagnosis mode, and a digital signal processor configured to extract an impedance parameter by detecting the output response of the fuel cell in the diagnosis mode, and predict a lifespan of the fuel cell according to the impedance parameter. The normal operation mode is configured to supply a voltage in response to a change of a load and the diagnosis mode is configured to predict the lifespan of the fuel cell.
Abstract:
A method and a system for supporting mobility of a mobile terminal in a distributed mobile network based on a SDN are disclosed. A method of supporting a fast handover of a mobile terminal in a node-B (eNB) includes the steps of: receiving a handover initiation message from the mobile terminal, the handover initiation message including identification information and signal strength of a target eNB; determining whether or not for a fast handover trigger using the signal strength of the target eNB and movement history of the mobile terminal previously stored; and when it is determined as the fast handover trigger, transmitting a handover request message and a rule for the handover to the target eNB by using the identification information of the target eNB.
Abstract:
Provided are a harmful site collection device and method for determining a harmful site by analyzing a connection between harmful sites. The harmful site collection device includes a harmful site database configured to store a URL of a harmful site; a web page collection and extraction unit configured to collect a web page indicated by the URL of the harmful site and extract a linked URL; and a harmful site connection analysis unit configured to calculate a connection with other web pages referenced within a web page of the linked URL to determine whether the web page is a harmful site. Accordingly, the harmful site collection device can determine a harmful site more easily only with information regarding the URL linked to the web page.
Abstract:
A network capable of detecting a DoS attack and a method of controlling the same, a gateway and a managing server included in the network are disclosed. The network capable of detecting a DoS attack comprises gateways. Here, each of the gateways receives packets, generates a self organizing map SOM by learning the packets and detects using the SOM whether or not a packet to be received is a packet of the DoS attack.
Abstract:
Provided is a reaction force compensation device capable of compensating for a reaction force caused by a motor that is continuously rotating. The reaction force compensation device is configured to compensate for a reaction force generated when a motor including a stator and a rotor, which is combined with the stator to be rotatable, is driven, and includes a housing disposed below the motor, and a rotation support member disposed between the housing and the rotor and configured to support the stator to be rotatable with respect to the housing. The stator rotates by a reaction force generated when the rotor rotates.
Abstract:
A method and an apparatus for propagating a message in a social network are disclosed. A method for propagating a message in a social network according to an embodiment of the invention can include: calculating a degree of connectivity of each user; calculating a propagation capability of each user by using the calculated degree of connectivity and a probability of distribution; choosing target users for propagating a message by using the propagation capability of each user; and propagating the message to nodes of the chosen target users.
Abstract:
A method and service server for providing passenger density information are provided. The service server for providing passenger density information of a car according to an embodiment of the invention may include: a motion vector detection unit that detects motion vectors generated by the movements of passengers from a captured image of the inside of the car; a head recognition unit that recognizes the heads of passengers from the image; and a density information generation unit that generates the passenger density information of the car by using one or more of the motion vectors, a result of head recognition of the passengers, and tag sensor information received from sensors installed in the car.
