If the two input signals are sinewaves at frequencies f 1 and f 2, then the output signal consists of frequency components at the sum f 1 +f 2 and difference f 1 −f 2 frequencies. In contrast, the harmonic and subharmonic mixers form sum and difference frequencies at a harmonic multiple of one of the inputs.
A slightly revised version of the smaller Essex V6 was introduced in 2004. With the same 96.8 mm (3.81 in) bore diameter as the 3.8 L and 4.2 L engines, but a stroke of 88 mm (3.46 in), displacement was 3,886 cc (237.1 cu in). [1] Overall engine output was unchanged from the earlier 3.8 L.
Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...

In a reciprocating quantum heat engine, the working medium is a quantum system such as spin systems or a harmonic oscillator. The Carnot cycle and Otto cycle are the ones most studied. [9] The quantum versions obey the laws of thermodynamics. In addition, these models can justify the assumptions of endoreversible thermodynamics. A theoretical ...
Social media criticized ESPN for its focus on Georgia's Parker Jones after his sideline interference penalty in the CFP Sugar Bowl quarterfinal game:

By 1957 the engine had grown to 283 cu in (4.6 L). Fitted with the optional Rochester mechanical fuel injection (FI) and a Duntov high-lift camshaft, it was one of the first production engines to produce 1 hp (0.7 kW) per 1 cu in (16.4 cc). The 283 was adopted by other Chevrolet models, replacing the 265 V8s.
