Disclosed is a prediction method for monitoring performance of power plant instruments. The prediction method extracts a principal component of an instrument signal, obtains an optimized constant of a SVR model through a response surface methodology using data for optimization, and trains a model using training data. Therefore, compared to an existing Kernel regression method, accuracy for calculating a prediction value can be improved.

Continuous droplet generators and methods are provided. In one embodiment, a continuous droplet generator includes an outer housing that defines a working liquid reservoir configured to maintain a working liquid. The continuous droplet generator also includes one or more heaters configured to change the phase of the working liquid and an evaporation-condensation tube positioned at least partially within the outer housing. The evaporation-condensation tube includes a gas inlet configured to receive a particle-containing gas flow, a gas outlet configured to export generated condensed droplets, a wall, an outer wall surface configured to be in contact with the working liquid, and an inner wall surface in contact with the particle-containing gas flow. The vapor is transported to the particle-containing gas flow through the evaporation-condensation tube by diffusion and vapor pressure difference to increase a relative humidity and grow particles within the particle-containing gas flow by nuclei heterogeneous condensation.

Disclosed is a keylock device for a circuit breaker. The keylock device for a circuit breaker comprises a closing lever configured to generate a closing operation of a mechanism, a trip lever configured to generate a trip operation of the mechanism, and a locking unit configured to allow a locked state of the locking unit to be maintained when the mechanism is in an ‘ON’ state, but to allow the locked state of the locking unit to be converted into a released state when the mechanism is in an ‘OFF’ state. Under these configurations, it is impossible to convert the current state of the keylock device into a locked state unless the mechanism of the circuit breaker is converted into an ‘OFF’ state. This may prevent the occurrence of an accidence due to the operator's unintentional ‘OFF’ state of the mechanism.

A light combined with a cable illuminates a cable-stayed bridge in which a deck slab is fixed by a cable, or a structure in which wires or cables are combined, so as to achieve improved visual landscaping effects. The light of the present invention comprises a frame (110), a lamp (120), a housing (130), and a switch (150). The frame (110) comprises: a through-hole (111) for the a cable (13) to pass therethrough; a plurality of lamp mounting grooves (112) formed along the circumference of the through-hole (111); and fastening holes (114) which are formed along the circumferential surface of the frame and communicate with the through-hole (111) in the horizontal direction, and each of which has an inner surface provided with a female screw thread. The lamp mounting grooves (112) are formed into steps such that lamp mounting grooves closer to the through-hole (111) are deeper than those farther away from the through-hole. The frame (110) further comprises a bar-shaped first fastening bolt (116) which passes through one of the fastening holes (114), and which has a circumferential surface with a male screw thread so as to engage with the female screw thread. The lamp (120) has light sources (121) fixed in the respective lamp mounting grooves (112) to emit light. The housing (130) accommodates the frame (110). The switch (150) controls the flickering operation of the lamp (120), and is installed within the housing (130).

Disclosed is a spectrally encoded coherent anti-Stokes Raman scattering (CARS) endoscope that is capable of spatially encoding spectral dispersions of two light sources having frequency difference as much as a Raman shift and overlapping two laser beams on a position where a sample to be measured is placed, thereby acquiring a spatial distribution of CARS signals.

The present invention relates to a 3-color multiplex CARS spectrometer. In the 3-color multiplex CARS spectrometer, Raman resonance is achieved for multiple molecular vibrations of a sample by the combination of a short-wavelength pump beam generated by a broadband laser light source and a long-wavelength Stokes beam generated by a stable laser light source, and another short-wavelength laser beam having a narrow linewidth is then introduced separately to serve as a probe beam that interacts with the laser-driven sample, thereby generating CARS spectral signals whose wavelength components can be resolved. Accordingly, the 3-color multiplex CARS spectrometer solves problem of the conventional 2-color multiplex CARS spectroscopy in which the wavelength decomposition of CARS signals, necessary for high spectral resolution, is not possible with broadband pump light causing the CARS spectrum distortion.
