Pulse Width Modulation is widely used in power electronics as a controller in power conversion and motion control. Among different types of modulating modes the Sinusoidal Pulse Width Modulation (SPWM) and Space Vector PWM are two common strategies in adjustable speed drive system. The Pulse width of SPWM varies with the Sine wave so as to restrain the lower order harmonics with easy control and large D C utilization. With successively improving reliability and performance of digital controllers, the digital control techniques have predominated ....etc

I am trying to model prestress in Hollow Concrete Slabs in Abaqus CAE in 3D. I have set up the model with rebars (truss elements) embedded in the concrete slab (Brick elements).

However there is no CAE usage for prestress which means that presumably, the prestress can only be introduced in the generated script (the journal file .jnl).

Although the manuals indicate how prestress can be introduced ( Initial Conditions' and Prestress Hold'), the problem is that I have no experience with scripting or using python programming.

Would using ....etc

The vibration load subjected to many products is the combination of several random processes corresponding to different application conditions, such as the various field road load inputs for automotive components. Sometimes the input loads are the combination of random and sinusoidal vibration. Due to the convenience of test setup and monitoring, the sinusoidal vibration sweep tests are often used for product durability validation by many automotive and consumer product manufacturers. It is therefore important to correctly correlate the sweep ....etc

ABSTRACT
This paper focused on the development of capacitor voltage
balancing methods in a flying capacitor multilevel inverter
(FCMLI) fed induction motor drive. For improving the
performance of flying capacitor multilevel inverter, a switching
pattern selection scheme is implemented. The proposed method
has been designed a seven-level flying capacitor multilevel
inverter by using sinusoidal pulse width modulation technique.
The selected pattern has been exposed to give superior
performance in load voltage, total harmonics dist ....etc
