Abstract:
An embodiment of the present invention relates to a method for performing spectrum sensing to detect a signal for a terminal of a primary user in each sensing node. The method for performing sensing may comprise the steps of: performing, by the sensing node, spectrum sensing to detect a signal for a terminal of a primary user; computing, by the sensing node, a local test statistic on the basis of the result of the spectrum sensing; calculating, by the sensing node, the transmission probability on the basis of the computed local test statistic; and transmitting, by the sensing node, sensing information to a convergence center on the basis of the calculated transmission probability. In this case, the convergence center can determine whether the signal for a primary user exists on the basis of the transmitted sensing information.
Abstract:
An apparatus for generating microbubbles in water from a mixed fluid in which a gas and a liquid are mixed. The apparatus includes a cylindrical body which includes an inlet coupled to a hose, an outlet, and a cylindrical space section defined therein. The diameter of the space section is greater than each diameter of the inlet and the outlet. An inner container member is fixed in the space section such that a tubular passage is formed. A circular first collision section is provided on the inner container member. The mixed fluid that has been introduced through the inlet collides against the first collision section and is thus stirred. An “L” shaped second collision section is provided on the inner corner of the body adjacent to the outlet. The mixed fluid that has passed through the passage collides against the second collision section and is thus stirred.
Abstract:
A method for receiving a measurement report includes: transmitting, by an apparatus including a coexistence manager (CM), a measurement request message for acquiring a measurement report from at least one device that uses a channel in a TV band to a coexistence enabler (CE); and receiving, by the apparatus, a measurement response message including the result of the measurement results from the CE. The measurement request message includes a first element indicating which of a primary detection, a detection of a device that uses the TV band, and a channel load measurement is requested. The measurement request message includes at least one of a start frequency, an end frequency, a channel list, and a measurement time related to the measurement, and the measurement report includes at least one selected from among the result of primary detection, the result of the detection of the device that uses the TV band.
Abstract:
A failure diagnosis method includes: generating a resource relationship map of resources to be managed on a network; and when a failure occurs in a certain service object within the network, extracting a topology relationship map from the resource relationship map by using the failed service object as a root node. The failure diagnosis method further includes searching a resource object caused the failure while checking related objects, starting from the root node in the topology relationship map.
Abstract:
The present invention relates to a composition for hard tissue formation and dentin, or dental pulp regeneration comprising ameloblasts, apical bud cells, or its culture fluid as an active ingredient. The ameloblasts, apical bud cells, or its culture fluid promotes the differentiation of odontoblasts, human dental pulp stem cells and osteoblasts, increases DSPP promoter activity, induces dental pulp regeneration of dental pulp stem cells, and induces hard tissue formation significantly in vivo, so that they can be effectively used for a composition for promoting hard tissue formation and dentin or dental pulp regeneration.
