این پایان نامه در ارتباط با اصلاح کننده های کیفیت توان و یا active power line conditionersکه به اختصار به aplc معروف است ، می باشد aplcیکی از مهمترین سیستمهایی می باشد که می تواند مشکلات مربوط به کیفیت قدرت ر سیستمهای توزیع را حل نماید. aplc به مجموعه ای از اکتیو فیلترها خطاب می شود. در حال حاضر هیچ تعریف منحصر به فردی جهت محاسبه توان برای شکل موجهای کلی ولتاژ وجریان وجود ندارد....
The world is severely affected by the Covid-19 pandemic health-care workers are hostile to work inside of COVID-19 hospital due social distancing. Supplying essentials food and delivering medicine in hospitals has a challenge. To address need World health organization certified sanitizing system solution for personnel surface decontamination. overcome problem developed automatic portable equipm...
are fitted overhead in the various departments. The number and size of the sprinkler tanks vary according to the requirements of each mill, hut 011 an average each tank is from 30 feet to 60 feet either way, and carries permanently about 6 feet of water. The water is mostly a clean supply derived from the municipal mains, though an emergency connection with the millpond by means of a pump is al...
To maintain a high system-uniformity and also acceptable water use efficiency in a solid-set sprinkler irrigation system, the total committed pressure variation to subunits should not exceed 20% of the pressure head of the sprinkler which operates with the average pressure. Although some references often recommend giving the major part of this pressure variation to laterals, a scientific and pr...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
Sprinkler and Fan Cooling Principles In sprinkler and fan cooling, the sprinklers create droplets that wet the cow’s hair coat to the skin. Fans are then used to force air over the cow’s body (see Figure 1), causing evaporative cooling to take place on the skin and hair coat. Heat from the cow’s body causes the moisture to evaporate. The droplet size must be large enough to wet the skin surface...
