This paper describes how the response curve of a video camera can be determined with the aid of a sheet of paper and two desk lamps only. The calibration process is based on the superposition law of incoherent light and does not make use of any calibrated measurement instrument.

In this paper the jitter suffered by the cells of the monomedia traffic streams which compose a multimedia data flow loading an ATM Multiplexer is analyzed. To this aim, a multimedia source is modeled as an arrival process defined as the superposition of heterogeneous arrival processes, each of which models one monomedia source. In order to capture the time relationships existing between the mo...

According to the standards, emission measurements are carried out in the frequency domain using a test receiver. In this paper the set-up and procedures of a measuring system in the time domain is presented. The advantage of this system is, that measurements can be done approximately 10 to 100 times faster. A special procedure to measure a pulse was already described in [2]. This paper presents...

The role of the superposition principle is discussed for the quantum-mechanical Carnot engine introduced by Bender, Brody, and Meister [J. Phys. A 33, 4427 (2000)]. It is shown that the efficiency of the engine can be enhanced by the superposition of quantum states. A finite-time process is also discussed and the condition of the maximum power output is presented. Interestingly, the efficiency ...
