Abstract: Disclosed are a method and an apparatus for video decoding that support a plurality of layers. The method for video decoding includes acquiring information indicating whether tile information exists and acquiring the tile information based on the information indicating whether tile information exists.

Abstract: Disclosed are a variable antenna and an apparatus for detecting a radio signal. The variable antenna includes: a first receiving unit including at least one liquid metal antenna element; a second receiving unit including at least one liquid metal antenna element having a length different from a length of the first receiving unit; and a gain control unit configured to electrically adjust lengths of the liquid metal antenna elements for one of the first receiving unit and the second receiving unit according to the frequency of a received signal, wherein each antenna array realized by the liquid metal antenna elements of the first receiving unit and the second receiving unit is arranged in a single bay.

Abstract: Disclosed are a parallel computing method for particle based simulation that may decrease a calculation delay due to data communication by simultaneously performing the data communication and a simulation calculation and increasing parallelism of a task, and an apparatus thereof. The parallel computing method for particle based simulation according to an exemplary embodiment to the present invention may include decomposing the whole calculation domain of a manager node into a plurality of sub-domains based on a grid macro-cell based orthogonal recursive bisection (ORB) method; allocating the decomposed sub-domains to worker nodes; and performing load balancing with respect to the worker nodes.

Abstract: A method of iris recognition using a cumulative-sum-based change point analysis and an apparatus using the same are disclosed. The method includes: transforming an iris image to a polar coordinated image having n×m pixel size and dividing the polar coordinated image into at least one cell; grouping the divided iris images into at least one of first groups having a predetermined number of cells, and at least one of second groups each having more cells than the first group has; performing a cumulative-sum-based change point analysis using a predetermined characteristic pattern value of each cell as a representative value; and generating a pattern vector by assigning a predetermined value to a cell having the change point and assigning a different value to other cells.

Abstract: A node disjoint path forming method for a hypercube having a damaged node which is capable of using unused nodes (surplus nodes) in an n-number of node disjoint paths each having a length of n with respect to n-dimensional hypercubes more than 4-cube, so that it is possible to obtain an n-number of node disjoint paths each having a length of n even though there are damaged nodes. The method includes the steps of a first step for forming a linear arrangement consisting of an n-number of integers (0, 1, 2, . . .
