In the audio world, the debate over closed-loop versus open-loop architectures has raged on for many years. Depending on the end-application or customer preference, valid arguments for both ...

Indian researchers have compiled an extensive review of all existing synchronization techniques for grid-connected PV systems. They divided the methods into open-loop and closed-loop systems and ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

In 2012, Automation World published an article looking at the decision factors faced when choosing electric or pneumatic actuators. More than a decade later, manufacturing engineers and OEMs still ...
