During the last years the medium voltage world has seen a strong increase in demand of flexibility, simplicity and automation of the distribution networks. The Smart Grids concepts have changed network’s needs and solutions with innovative design are required to satisfy these new demands. The standard IEC61850 is driving the innovation in the energy distribution devices enabling new functionali...

Today many substations exist with a multitude of different communication systems and architectures. Extension and retrofitting of stations are natural opportunities to introduce the IEC61850. It can be that an extended part of a substation is equipped with the new standard and then need to be integrated into the older part that is based on presently available communications. When retrofitting a...

بخش اورژانس یکی از شلوغ‌ترین بخش‌های یک بیمارستان است و بهبود عملکرد این تأثیر بسیاری در کیفیت ارائه خدمات دارد. اخیراً پژوهشگران به­‌دلیل تمرکز مهندسی تاب‌آوری مدیریت ناب بر کارایی سیستم‌ها توجه بسیار زیادی به دو دیدگاه کنار یکدیگر داشته‌اند. هدف پژوهش، رویکردی یکپارچه برای ارزیابی مبتنی شاخص‌های با ارتقای رضایت شغلی کاهش هزینه‌های درمانی واحد خصوصی است. منظور، ابتدا شناسایی مؤثر، مدل مفهومی مس...
