Abstract: A multi-channel drug detection method is proposed. The method may include inputting an electrical signal of a frequency included in a search range set in sensors of a sensor board, comparing magnitudes of electrical signals output by the sensors, and determining a frequency having the largest magnitude as a resonance frequency, the inputting, comparing, and determining being repeatedly performed. The method may also include determining, as a first resonance frequency, a resonance frequency determined in the inputting, comparing, and determining performed before a sample is inserted, and inserting the sample into the sensor board. The method may further include determining a second resonance frequency by repeating the inputting, comparing, and determining while moving the search range to search for a resonance frequency. The method may further include determining presence of a target material based on a difference between the first resonance frequency and the second resonance frequency.

Abstract: There are provided a method and an apparatus for cloud management, which selects optimal resources based on graphic processing unit (GPU) resource analysis in a large-scale container platform environment. According to an embodiment, a GPU bottleneck phenomenon occurring in an application of a large-scale container environment may be reduced by processing partitioned allocation of GPU resources, rather than existing 1:1 allocation, through real-time GPU data analysis (application of a threshold) and synthetic analysis of GPU performance degrading factors.

Abstract: A circuit for preventing power imbalance of a resonance-type power converter is proposed. The circuit may include a rectifier converting input alternating current (AC) into direct current (DC) and frequency-controlled first and second resonant converter modules configured to receive an output voltage of the rectifier divided into two stages. The circuit may further include a controller outputting a first frequency command for controlling a frequency of a pulse width modulation (PWM) signal supplied to a switching element of a first switching unit of the first resonant converter module. The circuit may further include a frequency compensator compensating for the first frequency command and then outputting a second frequency command for controlling a frequency of a PWM signal supplied to a switching element of a second switching unit of the second resonant converter module, so as to eliminate power imbalance between the first and second resonant converter modules.
