The paper presents a discrete spectrum analyzing method based on DFT, which can effectively reduce the phase error by choosing the window function with a real even function that has the linear phase spectrum. Since the traditional DFT algorithm could result in larger measurement error because of the spectral leakage and fence effect, the phase difference correction algorithm is proposed to cope with...
Experiences over the last decade measuring current profiles with Acoustic Doppler Current Profilers (ADCPs) have demonstrated significant capabilities. This paper briefly analyzed the main error sources of the Doppler profiles, and demonstrated that the measured precision can be quantified as the standard deviation of the horizontal error velocity. On this basis, a measurement quality assessment method...
Traditional Bayesian estimation uses stochastic but precise measurements or measurement models to estimate the state of a dynamic system. However, in many practical applications, interval measurements representing measurements affected by bounded errors or bias of typically unknown distribution are common and convenient. Recently, joint target detection and tracking in the presence of interval measurements,...
A system calibrating electronic instrument transformers with analogue and digital outputs is described. Its design is based on International Electrotechnical Commission (IEC) standards 60044-7, 60044-8 and 61850-9-1. The measurement uncertainty of the system is evaluated to be less than 0.05% for ratio error and less than 2 min for phase error.
3D video is currently attracting increasing interest, as it provides users greatly enhanced viewing experience. For such applications, multi-view video coding is crucial to handle the enormous amount of data. In this paper, an experimental analysis of multi-view video coding for various temporal and inter-view prediction structures is presented. We demonstrate the correlations among temporal and inter-view,...
