The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

Earth has a natural magnetic field that many animals use for orientation and navigation. With the development of technology, these natural systems have been exposed to high levels of man-made electromagnetism from the heavy usage of electric devices. This study aims to understand the possible effects of artificial magnetic fields on the behavioral responses of the earthworm, which is used in this study as a model organism in laboratory conditions. The 3 experimental groups, each composed of 20 earthworms, were exposed to 190–520 µT magnetic fields using a 1.

In this work, we have shown that the spin orientation in FM layer can be controlled by using the electrical field indirectly via the elastic mechanism between these layers. There is a critical electric field for each FM layer such as Fe, Fe3O4, which is the minimum electric field to switch the spin to the different directions in space.

From the principles of electrical engineering it is known that the 3-phase quantities of the 3-phase AC machines can be summarized to complex vectors. These vectors can be represented in Cartesian coordinate systems, which are particularly chosen to suitable render the physical relations of the machines. These are the field-orientated coordinate system for the 3- phase AC drive technology or the grid voltage orientated coordinate system for generator systems.

In the context of object-oriented programming, many solutions have been proposed to the problem of type inference [17,16,1,21,6,20,12], but the increasing interest in dynamic object-oriented languages is asking for ever more precise and efficient type inference algorithms [3,12]. Two important features which should be supported by type inference are parametric and data polymorphism [1]; the former allows invocation of a method on arguments of unrelated types, the latter allows assignment of values of unrelated types to a field.
