Choosing the operating system (OS) on which to build the application is the first step to building a PDA-based measurement device. Engineers almost always select between Palm OS or Pocket PC since ...

Network tomography is an indirect, measurement-based approach for inferring the internal characteristics of complex networks, such as traffic load, congestion points and failure localisation, ...

Quantum communication and measurement techniques constitute a rapidly evolving field that exploits the principles of quantum mechanics to enhance data transmission, security, and signal detection.

Measuring phase noise with a spectrum analyzer. The primary advantage of dedicated phase-noise analyzers. The cross-correlation method. Using a spectrum analyzer is the oldest, most straightforward, ...

One of the most significant movements in contemporary science within the last few centuries has been an increase in our ability to observe and analyze energy, matter and various interactions at the so ...

The measurement technique of an aspheric surface is mainly for the surface form and parameters. The surface form is the three-dimensional distribution of the surface in the spatial domain. The ...

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...
