In this paper, a sliding mode speed observer for direct torque controlled (DTC) induction motor drives is developed. The speed observer accuracy is guaranteed through the current observer. The rotor speed is estimated by ...

Multinational corporations (MNCs) are the creator of globalization. Selling their products on all over the world, using the world resources and spreading their production factors make them the main actor in this globalization ...

Purpose. - To determine the effect of two distinct intravitreal injection (IVI) techniques on the frequency of vitreous reflux (VR) and on treatment response at cumulative dosages in neovascular age-related macular ...

In this study, we define a new type of statistical limit point us-ing the notions of statistical convergence with respect to the Jp power series method and then we present some examples to show the relations between these ...

The present study was undertaken to investigate the effect of harvest time on the bioactive properties of Echinacea pallida and to determine the antioxidant effect of its extract in vegetable oils. E. pallida was harvested ...

The paper investigates the linkage between growth, finance and inequality in the light of inverted-U hypothesis in the European Union member countries in the period 1995-2018. The findings of the multiple equations analysis ...

An alternative way to generate electricity from solar energy is through the use of generators comprising Stirling engines with a parabolic collector. This study describes a parabolic collector with Stirling engine and ...

In this paper, Bertrandian Darboux Frenet ruled surface and striction curve of this surface is defined depending on the angle between the tangent vectors of Bertrand curves pair. Also, we examined the situation of the ...

Fabrication of conducting polymer networks based on polypyrrole/multi-walled carbon nanotubes (PPy/MWCNTs) modified graphite electrodes that were achieved with a single-step electropolymerization and potential use of these ...
