The exponential increase in carbon-dioxide resulting Global Warming would make the planet earth to become inhabitable in many parts of the world with ensuing mass starvation. The rise of digital technology all over the world fundamentally have changed the lives of humans. The emerging technology of the Internet of Things, IoT, machine learning, data mining, biotechnology, biometric, and deep le...

Unlike traditional power grids, smart grids have the advantage of bidirectional power flow and having distributed generations. Distributed generation systems are usually supplied by renewable sources which can cause unpredicted voltage fluctuations as a result of being intermittent. While traditional compensating devices deal with the problem of voltage fluctuation and reduced power quality wit...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...

background: in recent years, immunocompromised patients are at high risk for the development of invasive aspergillosis. due to the increase of antimicrobial resistance, natural agents with medicinal and immunomodulatory effects has gained more attention. honey is a natural substance with documented antimicrobial, anti-inflamatory and wound healing effects. objectives: the purpose of this study ...
