Abstract: A computing resource management system using software modularization in a cluster computing environment in which computing devices are connected, including an application process running on each computing device and an algorithm processing process configured to run independently of the application process and perform task processing on the application process, the computing resource management system including: a task managing system configured to receive a task request message from an application process requiring a task from each computing device; a process managing system configured to confirm an algorithm processing process of computing devices connected to the cluster computing environment, and determine whether there is an algorithm processing process in an idle state to which the application process requested for a task will be assigned; and a performed managing system configured to confirm a result of an application process whose task is performed by the algorithm processing process.

Abstract: The inventive concept provides a teaching method for teaching a transfer position of a transfer robot. The teaching method includes: searching for an object on which a target object to be transferred by the transfer robot is placed, based on a 3D position information acquired by a first sensor; and acquiring coordinates of a second direction and coordinates of a third direction of the object based on a data acquired from a second sensor which is a different type from the first sensor.

Abstract: A source node includes a topology information extractor configured to acquire information of a channel state between nodes included in a multicast network, and extract topology information of the multicast network. The source node further includes a relay node selector configured to select, from the nodes, a relay node to relay a packet transmitted from the source node, based on the topology information.

Abstract: A method and an apparatus for performing transmission power selection of a wireless access device and channel allocation in a combination manner, for resource management optimized for a wireless network environment supporting multimedia traffic are provided. In a method for managing a radio resource of at least one Access Point (AP) in a wireless communication network, a transmission power select operation for the AP is performed on each of a plurality of channel settings, and a network performance value is predicted. Optimized channel setting is selected among the plurality of channel settings depending on the predicted network performance value. The optimized channel setting and optimized transmission power corresponding to the optimized channel setting are allocated to the AP.
