This paper proposes a new structure for digital address decoders based on flip-flops with application in wake-up signal generators of wireless networks nodes. Such nodes equipped with this device can be utilized in Internet of Things applications where the nodes are dependent on environment energy harvesting to survive for a long time. Different parts in these wireless nodes should have an e...

background: decrease of economically accessible uranium resources motivates consideration of breeding of fertile elements such as thorium. material and method: thorium oxide fuel burn up calculation of a simulated research reactor cooled heavy water has been proposed in the present work using mcnpx 2.6 code. two 233u and 235u isotopes have been used as fissile element of thorium oxide fuel. 135...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
To determine the current risk of internal radiation exposure after the Chernobyl accident, the (137)Cs body burden of the inhabitants of Bryansk Oblast, Russian Federation was evaluated, from 1998 to 2008. The study population is composed of 84 666 people who visited Bryansk No. 2 Hospital. A whole-body counter was used for measurement of (137)Cs body burden. (137)Cs concentration was significa...
چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
The conceptual framework of the “Smart Grid” naturally takes the viewpoint of the grid, then works down into the details of its individual components. This is good and necessary, but there is an alternative approach that can complement and strengthen the “macrogrid” — to start from (very) small “nanogrids”. Nanogrids can be interconnected and aggregated into microgrids, and ultimately, through ...
