    Abstract: Disclosed herein is a system and method that analyze a plurality of types of interactions between devices and between users, predict intimacies therebetween, find small groups within a certain group based on the intimacies, and then detect outcasts. The system for detecting a small group and an outcast includes a data collection unit for collecting data based on interactions between objects. A data analysis unit analyzes the data. An intimacy prediction unit calculates intimacies between objects based on the analyzed data. A small group configuration unit detects one or more small groups from a certain group, based on the calculated intimacies. An outcast detection unit detects an outcast, based on presence or absence of each object in the one or more small groups and the intimacies.

    Abstract: Disclosed herein is an apparatus and method that enable data sharing to be performed between short-range/middle-range/long-range mobile terminals by minimizing specific intervention of a user. The apparatus includes a social relationship management unit for managing social network group information formed by a user while the user utilizes a social network service. A device recognition and authentication unit identifies a mobile terminal of another party attempting to make a connection and allocates a data communication channel for data exchange, based on device information received from the mobile terminal of the other party attempting to make a connection and the social network group information. A shared data setting unit sets data to be shared with the mobile terminal of the other party between which the data communication channel has been established. A shared data transmission unit transmits the data to be shared to the mobile terminal of the other party.

    Abstract: Disclosed herein are a server and method for providing collaboration service, and a sociality management server. The server includes a service provision unit and a space construction unit. The service provision unit sets up collaboration service corresponding to the results of combining functions of at least two collaboration terminals based on sociality values corresponding to the at least two collaboration terminals. The space construction unit constructs a service provision device space via which the collaboration service is to be provided. The service provision unit provides the collaboration service to the at least two collaboration terminals via the service provision device space.

    Abstract: Disclosed herein are a hybrid download method and apparatus for multiview streaming. The hybrid download method includes requesting a group download for an n−1-th segment from a server, playing an n−3-th segment at a viewpoint VP1 of a viewer, when a group download request for the n−1-th segment is completed, making a group download request for an n-th segment, when a change in a viewpoint of the viewer occurs at a time at which an n−2-th segment is played, playing a low-quality n−2-th segment at a viewpoint VP3, when the group download for the n-th segment is completed, requesting a single download for a high-quality n−1-th segment corresponding to the viewpoint VP3 from the server, and when the single download for the high-quality n−1-th segment corresponding to the viewpoint VP3 is completed, playing the high-quality n−1-th segment at the viewpoint VP3.

    Abstract: Disclosed herein are an apparatus and method for removing a self-interference signal. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives an upstream signal for removing self-interference, generates a downstream signal for channel estimation, replicates a self-interference signal in a time domain and a self-interference signal in a frequency domain using the upstream signal and the downstream signal, and removes the self-interference signal from the upstream signal using the replicated self-interference signal in the time domain and the replicated self-interference signal in the frequency domain.

    Abstract: Disclosed herein are a method for estimating a self-interference signal based on iterative estimation and an apparatus for the same. The method is configured to transmit two preamble signals from the transmission antenna of one terminal to the reception antenna thereof, to estimate third-order nonlinear distortion, which distorts a self-interference signal, based on a transmission signal and a reception signal for each of the two preamble signals, to update the reception signal by eliminating the third-order nonlinear distortion therefrom, to re-estimate the third-order nonlinear distortion based on the updated reception signal, and to estimate the self-interference signal based on the final third-order nonlinear distortion, which is acquired by repeatedly re-estimating the third-order nonlinear distortion as many times as a preset number of iterations.
