Most software developers have probably heard of and even had experiences with the object-relational impedance mismatch (often addressed with ORM tools), the object-XML impedance mismatch (often ...

As data-communication speeds increase beyond 3 Gbps, signal integrity becomes crucial for successful data transmission. Board designers try to eliminate every impedance mismatch along the high-speed ...

There are a few classic physics problems that it can really help to have a mental map of. One is, of course, wave propagation. From big-wave surfing, through loudspeaker positioning, to quantum ...

For nanoelectromechanical (NEM) resonators 1, control of vibrational energy exchange between the resonator and its supports is highly desirable: High Q-factor resonators are attained by suppressing ...
