electromagnetic forming is a high energy rate forming process. in this process, an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for assembly of parts as an innovative method. in this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...

Measuring the level of electromagnetic interference emitted by electronic devices is an important part of the process of production and development of these devices. Today, these measurements are performed by specialized laboratories that are equipped with an anechoic or semi-anechoic chamber. For manufacturers of electronic devices, it would be beneficial if a Gigahertz Transversal Electromagn...

The switching device turn-on and turn-off process will produce high-frequency electromagnetic interference, based on the finite element method ANSYS software with powerful computing capabilities, has been widely used in complex electromagnetic field calculations. In this paper, ANSYS software to model and analyze the insulated gate bipolar transistor (IGBT) and quantitative distribution of elec...

OBJECTIVES The positive aspects of social support and its impact on health have been studied extensively. However, there may also be negative effects of social environments on the diabetic patient. This study developed and validated a new diabetic unsupportive social interaction scale (USIS), including two subscales: interference and insensitivity. METHODS A list of 22 items depicting unsuppo...
