Zero-thermal-expansion (ZTE) materials are widely used in precision optics, cryogenic equipment and sensors, where even small ...

We consider the generic problem of steady conduction through a slot traversing a non-conducting plate that separates two semi-infinite conducting regions. The current-density field is conservative; ...

People not in the refrigeration business often think that refrigeration equipment produces cold air; in fact, the equipment is actually removing heat from air and leaving what’s left — the cold. When ...
