As mechanical components and systems become more complex, the technology for diagnosing product failures is becoming more prominent. In particular, the use of deep learning methods such as CNN in fault diagnosis brings the accuracy of sorting out failures without screening out fault features to close to 100%. But so much so that what data is input is used as an important factor in determining accuracy. In this paper, when diagnosing faults of a vibration time series data of the compressor rotor with CNN, the type of image conversion performed to input data was largely divded into two parts, RP and Scalogram, depending on the conversion to the frequency domain, and it reveals which algorithms are more suitable for fault diagnosis. Experiments have shown that scalogram that has been converted to frequency domain have higher accuracy, F1-score, etc.

선폭 축소된 반도체 레이저를 이용하여 루비듐 원자의 D₂ 전이선에 대해 도플러 효과가 제거된 편광 분광을 실시하고 광펌핑 편광 분광 이론과 비교하였다. 펌프광이 충분히 약했을 때 실험에서 얻어진 분산모양의 스펙트럼은 단일 주기 광펌핑 이론과 잘 일치하였다. 또한 편광 분광 신호를 직접 오차신호로 사용하여 공진기 길이를 보상한 결과, 주파수 변조를 하지 않고서도 레이저 주파수를 원자의 초미세 전이선에 안정화시킬 수 있었다. Doppler-free circular polarization spectroscopy in (87)^Rb D₂ line has been carried out by using a diode laser whose linewidth was narrowed by an external cavity, and experimental results were compared with an optical pumping polarization spectroscopy theory. A dispersive spectrum obtained in a weak pump beam was completely fitted to a single cycle optical pumping theory. The laser frequency was locked to a Rb atomic hyperfine transition line without any frequency modulation by using the dispersive curve as an error signal.

This paper focuses on the combustion characteristics of blended coals with bituminous and sub-bituminous coals under air and oxy-fuel combustion conditions. The effects of oxygen concentration and blending ratio on the combustion characteristics were experimentally investigated using a thermogravimetric analyser (TGA). Characteristic temperatures including ignition, burnout temperature and activation energy were determined from TG and DTG combustion profiles. As oxygen concentration increased and the presence of sub-bituminous coal, characteristic temperatures and activation energy decreased. The ignitability, reactivity and kinetics have all been greatly improved under oxy-fuel combustion conditions. Based on this, co-firing with bituminous and sub-bituminous coals under oxy-fuel combustion conditions may be suggested as an alternative method to the fuel flexibility and cost-effective power production with carbon capture and sequestration.

In this study, effect of particle size on combustion characteristics and kinetics in the co-combustion with bituminous and sub-bituminous coals is experimentally investigated using a TGA and a laboratory-scale burner. Characteristic parameters including volatile matter release, ignition, burnout temperature and activation energy are determined from TG and DTG combustion profiles. Distribution of flame length and mean particle temperature is investigated from the slit-burner system. The purpose of this study is to provide fundamental information for developing reaction model in the numerical simulation and to provide operating conditions in blended coals power plants. As coal particle size decreased and volatile matter content increased, characteristic temperatures and activation energy decreased. The ignition, burnout characteristics and activation energy showed a linear effect on particle size and blending ratio. These results indicated that the control of the coal blending ratio can improve the combustion efficiency for sub-bituminous coals and the ignition characteristics for bituminous coals.

The purpose of this study was to examine the nature and characteristics of competitive aspect in sporting experience through phenomenological approach. The conclusion was followings: 1. The classified characteristics and result of tough and individual game are appeared in double with classification of meaning category in the physical contacting games. Physical contacting games were mostly appreared toke tough games. Thus, human relationship would be meaning ful in the physical contacting games. The meaning ful category (which is experienced in the competitive aspect of physical contacting game) reflects the characteristics of meaning category experienced in group game. 2. The results of the study indicated that to be time and body affect in women sport such as basketball, bowling, and taekwondo while, body and space influence men sport such as football, golf, boxing, judo and taekwondo and so on.. 3. I could find that the elements of meaning category of participants in this study through experience of competition of non-physical contacting games such as golf, shooting, bowling, skiing etc reflect the elements of meaning category in individual games. This would be caused by that probably the sporting events that doesn't need physical contact are mostly individual games. The common meaning category of participants of non-physical contacting games in this study show time and body. It provides and opposite view about common opinion that non-physical contacting games are static and not active by its attribute of the games. The vivid time and body that are meaning categoty experienced with non-contacting games show that they are the field of vivid meaning experience on the assumption of live movement which th competitive aspect is alive.
