Researchers have developed a powerful computational framework that shows how carefully optimized nanotube shapes can amplify electromagnetic field concentration by more than 30 times compared to ...

Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.

Kristy Ambrose has been writing professionally since 2010. She dabbles in various genres, but her favorites are fantasy and science fiction. She creates everything from fanfiction to serialized novels ...

Typically, when we think about forming metal parts, we think about beating them with hammers, or squeezing them with big hydraulic presses. But what if magnets could do the squeezing? As it turns ...

Electromagnetic fields are all around us — power lines and household appliances produce extremely low frequency EMFs, whereas cell phones and Wi-Fi devices emit radiofrequency EMFs. The general ...

Calculate annual % change by dividing start by end value, raising to inverse years, minus one, times 100. Ex: a drop from $15M to $10M over 2 years is a 18.4% average annual decline. This calculation ...

Among the things some people worry about is living near power lines. Not just because of the obvious danger if a live wire were to break and fall into a yard or on a house, but because they're ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

Abstract: The doubly-fed induction generator (DFIG) is prone to losing control due to high rotor EMF during severe grid faults. Therefore, calculating the maximum rotor EMF of DFIG under different ...

Abstract: In order to improve the performance of the inductive displacement sensor, ANSYS Maxwell was used to compute and analyze the induced EMF(electromotive force) produced by the sensor in this ...

Solvej Balle’s “On the Calculation of Volume” rethinks the familiar story of the endlessly repeating day. By Hilary Leichter Hilary Leichter is the author of the novels “Temporary” and “Terrace Story.

The year 2024 closed out with a significant radio deal as Educational Media Foundation announced it had reached an agreement with Salem Media Group to acquire seven of its FM signal properties, ...
