This paper presents the effective and reliable speed control of PMDC motors under variable loads and reference speeds. As is known DC motors are more preferred in industrial practices. This is that, the PMDC motors don’t ...

Power electronics converters are the periodically changing systems because of their switching structures. For this reason, the dynamic attitudes of the converters show nonlinear characteristics. The analysis and design ...

This paper examines globalization’s effects on the change in Turkish foreign policy towards Syria in a comparative perspective. Through the 1990s Turkish foreign policy towards Syria was shaped by realist parameters as ...

The main objective of meta-analysis is to aggregate the results of multiple scientific studies on a specific topic. Instead of aggregating the results of different studies, different methods are aggregated with the help ...

The purpose of this paper is to explore the construct of student satisfaction and analyze its relationship with student loyalty in the context of state and private universities. A 45-item Turkish questionnaire adapted ...

We present electronic structure and transport calculations for hydrogen and lithium chains, using density functional theory and scattering theory on the Green’s function level, to systematically study impurity effects ...

This study is focused on the investigating of a power plant generator in reverse power condition. For this purpose, reverse power data were collected from a Combined Heat and Power Plant generator protection relay. The ...

With arc welding machines, welding is only performed at optimum operating points. Determination of optimum operating points is important so as for welding machines which will be produced in future to be developed in a ...

The most important factor for designs in which friction materials are used is the coefficient of friction. The coefficient of friction has been determined taking such variants as velocity, temperature, and pressure into ...

The transformation process of the data kept in data warehouse into usable information for decision support system is very important. In this process, it is necessary to reveal the useful data that can meet the needs of the ...
