Online partial discharge (PD) measurements have long been used as an effective means to assess the condition of the stator windings of large generators. An increase in the use of PD online measurement systems during the last decade is evident. Improvements in the detection capabilities are partly the reason for the increased popularity. Another reason has been the development of digital signal ...
Introduction and Aim: Conventional psychiatric therapies have shortcomings in the treatment of schizophrenia spectrum disorders and have little effect on skills and community-based areas. Therefore, the present study aimed to investigate the role of community return program (CRP) as a community-based complementary therapy method in increasing readiness for discharge and post-discharge adjustmen...
Based on the physical phenomena of optical effects produced by the partial discharge (PD) and on the characteristics of fluorescent fiber sensing of weak fluorescent signals, a PD measurement system using a fluorescent fiber sensor was designed. The main parameters of the sensing system were calculated, an experimental testing platform for PD simulation in the lab was established, and PD signal...
Relative erosion rates of the discharge cathode assembly of a 30-cm ion engine are measured using laser-induced fluorescence. Molybdenum and tungsten erosion products are interrogated downstream of the discharge cathode assembly during beam extraction. Erosion of the discharge cathode assembly is characterized for both keepered and unkeepered configurations. The erosion increases with both disc...
ین پایان نامه با هدف سنتز و شناسایی چهار نوع از نانو ذرات آغاز می شود. نانو ذرات آلوم اکسان از واکنش بوهمیت و کربوکسیلیک اسید مربوطه حاصل شدند. هدف از سنتز این نوع نانو ذرات ساخت غشاهای عامل دار شده با خاصیت آب دوستی و انتخاب پذیری جهت جداسازی روغن از مخلوط های آب و روغن، می باشد. tg-dta، ftir، sem، tem، uv/vis spectrophotometer، digital camera،contact angle measurement goniometer، ultrasonic b...
