Acoustic Vector-Corrected Impedance Meter [PDF]
We describe the development of a novel instrument intended for the measurement of the acoustical reflection coefficient of materials. The instrument effectively implements a one-port vector-corrected network analyzer in the acoustic, rather than the ...

A wearable motion capture device able to detect dynamic motion of human limbs
Current wearable motion capture technologies are unable to accurately detect dynamic motion of human limbs due to drift and instability problems. Here, the authors report a wearable motion capture device combining tri-axis velocity sensor and inertial ...

Self-calibration measurement and uncertainty evaluation of lens focal length based on Fabry-Perot Interferometer [PDF]
This paper proposes a self-calibration method for lens focal length measurement based on a Fabry-Pérot (F-P) etalon, and investigates uncertainty evaluation strategies in scenarios where measurement errors affect the results through indirect propagation.

An object-oriented model of measurement systems [PDF]
This paper presents a general object-oriented model for measurement systems. The limitations of the conventional function-oriented models are examined in the light of the generalized concept of measurement and its theoretical framework proposed ...

On the Teleportation of Continuous Variable [PDF]
The measurement procedures used in quantum teleportation are analyzed from the viewpoint of the general theory of quantum-mechanical measurements. It is shown that to find the teleported state one should only know the identity resolution (positive ...

Acoustic measurements and instrumentation [PDF]
A few selected topics will be discussed. Each had a major influence in setting a new trend. The discussion will include: the significance of Wente's condenser microphone in freeing acoustic measurements from the constraints of contemporary microphones; the effect of Maxfield and Harrison's paper on the analysis and synthesis of acoustic devices; the ...

Measurement properties of quality of life measurement instruments for infants, children and adolescents with eczema: protocol for a systematic review [PDF]
Background: Eczema is a common chronic or chronically relapsing skin disease that has a substantial impact on quality of life (QoL). By means of a consensus-based process, the Harmonising Outcome Measures in Eczema (HOME) initiative has identified QoL as
