The present invention relates to a method of performing a Listen Before Talk (LBT) procedure by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of detecting a LBT failure based on a first LBT failure parameter set; receiving a second LBT failure parameter set before transmitting a LBT failure report; and if the second LBT failure parameter set requires more frequent LBT failure report than the first LBT failure parameter set, transmitting the LBT failure report related to the LBT failure.

An apparatus and method for determining an amount of chemical input, and more particularly to an apparatus and method for determining the amount of a chemical to be added, which is necessary to achieve target water quality, wherein a required chemical concentration can be accurately calculated based on the temperature of the water and the target turbidity of the water includes an information-receiving unit configured to receive at least one of environmental information, chemical information, and water-quality information of the water present in a specific area and a chemical input determination unit configured to derive a multiple regression equation based on the received environmental information, chemical information, and water-quality information and to determine the future input of a chemical that is added to satisfy a target turbidity of the water present in the specific area based on the multiple regression equation.

Apparatus and method for determining chemical input

A apparatus may extract temperature for each region of a feed water and steam system of a thermoelectric power plant with respect to a combustible combination including one or more combustibles, extract one or more vectors for each region from the temperatures extracted for each region, generate one or more combustible clusters, each cluster including one or more combustible combinations having similar properties from the extracted vectors, and extract a characteristic component of a combustible combination that increases or decreases a boiler performance index from among one or more combustible combinations included in the one or more combustible clusters.

Influence analyzing apparatus for analyzing influence of combustibles

An apparatus for detecting abnormal vibrations of a rotor includes a vibration information receiver configured to receive at least one type of information among vibration information regarding one or more dimensions distinguishing locations and directions of the rotor and rotor rotation information including a number of rotations of the rotor, a multivariate management index calculator configured to calculate multivariate management indexes from the vibration information regarding the one or more dimensions, and an operation index extractor configured to determine an abnormality in vibration characteristics of the rotor when a Hotelling's T-squared value is greater than an upper control limit and extracts an operation index causing the abnormality in the vibration characteristics of the rotor from one or more operation indexes. An abnormal vibration in a rotor is detected based on four-dimensional (4D) vibration information distinguishing locations and directions of the rotor.
