Abstract: Provided is a structural health monitoring system of a rotating object such as a turbine blade, which gives easy and intuitive information to field managers on the damage location and the damage size of the rotating object by computing and visualizing correlations between damage and propagating ultrasonic wave. The structural health monitoring system for a rotating object comprises an ultrasonic generation system which generates an ultrasonic signal by irradiating a pulse laser beam to a point of the rotating object, a pulse laser control system which adjusts the irradiating time of the pulse laser beam, an ultrasonic measurement system which measures a generated ultrasonic signal at a point of the rotating object away from the point irradiated by the pulse laser beam and a damage detection system which provides information of damage existence, damage location and damage severity by visualization of monitored ultrasonic signals.

Abstract: The present disclosure relates to a method for preparing a multi-level pore zeolite, including: (A) a step of mixing a silicon precursor, an aluminum precursor, a phosphorus precursor, a structure directing agent and water; a step of (B) adding phenylphosphonic acid, carbon black or a mixture thereof to the mixture prepared in the step (A) and mixing the same; a step of (C) crystallizing the mixture prepared in the step (B) by heat-treating the same; and a step of (D) calcining the crystallization product, and utilization of the prepared multi-level pore zeolite as a catalyst for hydroisomerization of normal paraffins. The catalyst exhibits improved isoparaffin yield when it is used as a catalyst for hydroisomerization of normal paraffins such as diesel or lube base oil by supporting an active metal component because residence time of reactants and products in the zeolite crystals are decreased due to mesopores and the proportion of external acid sites to total acid sites is low. Also, cloud point and pour point are effectively improved and high hydroisomerization reactivity is achieved without product loss.

Abstract: A class-D amplifier includes an error amplification circuit, a duty signal generator, a level selection circuit, a driver and control block and an output stage. The class-D amplifier divides peal levels of an error signal into multi-level and changes a scheme for modulating the error signal when the error signal crosses each level boundary of the multi-level thereby to have an effect such as the error signal is folded. Therefore, the class-D amplifier drives output nodes with multi-level and thus the class-D amplifier may increasing efficiency while reducing EMI.
