Drill and Fill: Installers thread pipe into a hole a few inches wide and over 100 feet deep. As wind and solar hog the alt-energy spotlight, this technology has remained underground. "You're not ...

Abstract: This paper presents an improved lumped element model for clamped, circular-shape, piezoelectric micromachined ultrasonic transducers (pMUTs). A small signal equivalent circuit is developed ...

Have you switched your heating on yet? With temperatures now dropping it's certainly tempting to but, despite living in a draughty house in the north of England, I rather stubbornly am hoping to ...

The electric air taxi race is no longer science fiction — it's a boardroom strategy. Airlines are pouring money and credibility into electric vertical take-off and landing (eVTOL) startups, betting ...

Abstract: A novel small-signal model for bulk FinFETs is presented. A parallel combination of resistance-inductance networks originated from the self-heating is obtained. A new transfer gain model is ...
