Accurate modelling of the Electric arc furnace (EAF) is necessary to study its impact on power systems. Here, a new model for EAF presented in which both non-linearity and time-varying characteristics are taken into account. The consists seven parallel current sources represent fundamental harmonic currents. Magnitude phase magnitude second seventh harmonics considered as updated every 0.01 s. ...

Demand forecasting is a key parameter to achieve optimal supply chain management at different levels. The basic metals industry one of the most energy-intensive industries in electricity chain. impossibility large-scale energy storage, reservation constraints, and its high costs, limitations on transmission lines capacity, real-time response priority strategic demands, variety rates hours seaso...

One of the newest advancements in manufacturing and project management is Building Information Modeling (BIM) which uses creative processes for production, analysis, building information. On other hand, output Geographic System (GIS) model includes one or more actual locations, satisfy all needs. It provides points related to BIM tool it creates a 3D visualizing optimum location. Integration GI...

BACKGROUND Regarding the relationship between blood pressure (BP) and shift work (SW), previous studies have reported contradictory results. In the present study, we used Bayesian multilevel modeling to evaluate the association of SW and BP after controlling some confounding factors. METHODS Data of this multicenter historical study were extracted from annual observations of the male workers ...

Background Scorpions are among the world's venomous arthropods, they sting humans every year, suffering painful symptoms or losing their lives because of the venom. Odontobuthus doriae Thorell 1876 (Arachnida: Scorpionida: Buthidae) is a scorpion of medical importance and therefore its geographical distribution in Isfahan Province has been studied. Methods This descriptive cross-sectional stu...
