In recent years, an increasing number of Chemical Engineering Software (CES), which play an important role in improving efficiency in the petroleum industry, has been introduced to the market. Generally, software is the product of intellectual creativity, but protection of the intellectual property residing in software is the subject of some controversy. This paper explores the ...
One of the most important goals of disaster management teams is to protect the assets and infrastructures of the community in the event of accidents such as wildfires and floods. This issue requires appropriate operations of all disaster management teams and analysis of available information for suitable decision making and consequently timely response. A mixed integer mathematical model is pre...
The change in the topology of active distribution networks (ADNs) is one of the essential challenges that might affect the protection schemes. The conventional protection schemes based on base topology result in some coordination constraint violations in other topologies due to the outage of upstream substations and distributed generation units. In this article, new combinational and adaptive p...
The aim of this paper is to extend a hybrid protection plan for Power Transformer (PT) based on MRA-KSIR-SSVM. This paper offers a new scheme for protection of power transformers to distinguish internal faults from inrush currents. Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...
Background and purpose: Mosquito control and personal protection from mosquito bites is currently one of the most important measures to control mosquito born diseases. The use of repellents is an obvious practical and economical means of preventing the transmission of these diseases to human. Dimethyl phthalate (DMP) is one of the safest repellents, which is used alone or in combination with ...
In this paper, the system stability-constrianted optimal protection coordination (SSCOPC) as stochastic problem in the microgrid with grid-connected and islanded operation modes, including renewable energy sources (RESs) and energy storage systems (ESSs), is presented. This problem to optimal regulation of the dual setting overcurrent relays (DSORs) and selecting the reactance size of fault cur...
